Abstract:

The article describes the diesel generator complex which consists of two diesel generators. In order to save fuel, it is advisable to choose one diesel generator of inverter type, i.e. to switch it to a variable speed mode. The buffer storage device is used as a part of the power plant in order to ensure the required parameters of the generated electricity under peak loads, as well as when the generator is operating at the limit of rated power. There has been given the control algorithm and transient processes of the charge / discharge of the buffer storage device in a diesel generator power plant. The power plant that consists of a classic diesel generator and a variable speed diesel generator unit (valved generator) has been chosen as an object research. A block diagram of the power plant conducting is proposed, as well as a power transformer topology of a variable-speed diesel generator based on a step-down pulse-width converter. There has been presented an algorithm for controlling the connection of a buffer storage device depending on its charge and the load power value both in stand-alone mode and in parallel operation of generator sets. In the MatLab Simulink computer environment a simulation model of a power plant was developed and transient processes of load switching, as well as charge / discharge of a buffer energy storage device were studied. An electrical circuit diagram of an experimental bench of a variable-speed diesel generator set is illustrated. The results of experimental studies of dynamic modes of operation on a prototype variable speed diesel generator with a power of 3.2 kW are also presented.

Abstract:

Feedback energy recycling is one of the most important energy-saving technologies of diesel generator sets. The current methods of recovering feedback energy are mainly by the energy storage device. However, this method has disadvantages such as the big cost and large area of space. In order to improve the efficiency of feedback energy recycling, the use of feedback energy saving diesel generator set is an effective solution. By improving diesel generator set control system algorithm and ensuring the safety of diesel generator sets, the feedback energy can drive diesel generators running. After the actual verification, this solution is correct, the improved algorithm is effective and the energy-saving effect significantly.

Abstract:

Telecommunications industry requires efficient, reliable and cost-effective hybrid power system as alternative to the power supplied by diesel generator. This paper proposed an operational control algorithm that will be used to control and supervise the operations of PV/Wind-Diesel hybrid power generation system for GSM base station sites. The control algorithm was developed in such a way that it coordinates when power should be generated by renewable energy (PV panels and Wind turbine) and when it should be generated by diesel generator and is intended to maximize the use of renewable system while limiting the use of diesel generator. Diesel generator is allocated only when the demand cannot be met by the renewable energy sources including battery bank. The developed algorithm was used to study the operations of the hybrid PV/Wind-Diesel energy system. The control simulation shows that the developed algorithm reduces the operational hours of the diesel generator thereby reducing the running cost of the hybrid energy system as well as the pollutant emissions. With the data collected from the site, a detailed economic and environmental analysis was carried out using micro power optimization software homer. The study evaluates savings associated with conversion of the diesel powered system to a PV/Wind-Diesel hybrid power system.

Abstract:

Particulates from diesel generator operation are a known air pollutant with adverse health effects. In this study, we used low-cost particulate matter (PM) sensors to monitor PM2.5 in a diesel generator plant. We compared the measurement results from a PM sensor and a reference instrument (DustTrak), and we found a high correlation between them. The data overestimation or underestimation of PM sensors implied the need for data calibration. Hence, we proposed a data calibration algorithm based on a nonlinear support vector machines (SVM) model, and we investigated the effect of three calibration factors on the model: humidity, temperature, and total volatile organic compounds (TVOC). It was found that the TVOC correction coefficient has great influence on the model, which should be considered when calibrating the low-cost PM sensor in diesel generator operation sites. A monitoring network with six low-cost sensors was installed in the diesel generator plant to monitor PM2.5 concentration. It was found that normal diesel generator work, diesel generator set handling work, and human activity are the most dominant ways of producing particulate matter at the site, and dispersion is the main cause of increased PM2.5 concentrations in nonworking areas. In this study, PM2.5 emissions from two different diesel generators were tested, and PM2.5 concentrations at monitoring points reached 220 μg/m3 and 120 μg/m3, respectively. This further confirms that diesel generators produce many respirable particles when working.

Abstract:

Various faults in ship’s electrical power system, primarily those connected with diesel-generators, governors and automatic voltage regulators, may lead to oscillations in generator load, voltage and frequency. If those transients are large enough, a partial or total blackout may occur. In order to prevent such events, it is very important to get an insight into dynamic behaviour of electrical energy sources on board vessel. In this paper, a dynamic model in the time domain of marine diesel-generator is presented. The model is realized in the MATLAB/SIMULINK environment and consists of three main parts: the synchronous generator model, diesel-engine governor model and voltage regulator model. Simulation of a sudden loss of one generator when two generators are running in parallel is performed. Simulation results show that the presented model is fully applicable for the purpose of analysis of the marine diesel-generator dynamic behaviour during transient periods.

Abstract:

The paper discusses the possibilities of using hybrid composite structures to overcome the energy shortage in Iraq, as well as the development of an efficient system of solar, wind turbine diesel generators. In this article, a Diesel Generator is combined with a wind turbine and batteries on the basis that the sun’s energy is not constant over time. The simulation was carried out using the HOMER program, which allows a detailed analysis of the volume and power of energy generated by the proposed system. The HOMER program is used for technical, economic, and environmental assessments. According to the results of the study, it was established that the most effective solution for saving electricity and overcoming energy shortages is a system consisting of renewable sources, as well as a diesel generator with batteries. The results also show that renewable energy sources used in the hybrid system provide about 69.2% of the electricity generated. This certainly improves the reliability of the electricity generated and reduces the fuel and maintenance costs of diesel generators, as well as saving the environment. The analysis of optimal systems is explained in detail to find the most achievable autonomous system.

Abstract:

The article considers the problem of improving power efficiency of the diesel generator power plants as one of the priority objectives for development of low power generation in Russia. Improving energy efficiency for autonomous facilities is directly related to the optimization of hydrocarbon fuel consumption by marine diesel engines. It is possible to optimize the fuel consumption of internal combustion engines by creating variable-speed diesel generators (VSDG), which are diesel-generator units with semiconductor converters, i.e. systems with valved generators. Optimization of specific fuel consumption by VSDG is provided by the forced regulation of the rotational speed of the shaft of the internal combustion engine in accordance with its multi-parameter characteristic in the shared load conditions of the power plant. The synchronous electric machine is used as a generator as part of a ship power station. Its use in the classic constant-speed diesel generators is more preferable than an asynchronous electric machine. In the development of VSDG - valved power plant - the use of an electric machine with a phase rotor as a generator is technically justified, because the installed capacity of the frequency converter in the rotor circuit of an asynchronous generator with a phase rotor is determined by the sliding power and, with a limited range of speed control, SDGV significantly reduces the installed capacity of the electrical equipment. Such power topology of a ship’s power plant is called VSDG based on a dual-power machine. There has been proposed to consider a variant of a ship power plant based on VSDG with a dual-power machine. Its functional diagram and mathematical model are developed. A structural diagram is presented and dynamic modes of the amplitude and frequency of the generated voltage are modeled during electrical load switching.

Abstract:

The use of electric propulsion systems in PSVs in Brazil has recently increased, leading to be the standard for most support vessels. In those ships, the common arrangement uses high speed Diesel generator sets for power generation and induction motors driving propellers, reporting significant reductions in the fuel consumption and exhaust emissions compared with mechanically propelled PSVs. However, further abatements in these parameters could be achieved by implementing other technologies for power production. In this work, the use of medium- speed Diesel generator sets and energy storage technologies in electrically propelled PSVs is evaluated. For the above, the fuel consumption, exhaust emissions, mass, volume and acquisition costs of four arrangements are estimated and compared. Two of the arrangements are equipped with medium-speed Diesel generator sets, two with energy storage units and one with high-speed Diesel generator sets. Energy storage appears as interesting alternative for decreasing fuel consumption and emissions by optimal loading of Diesel engines. Medium speed generators also showed reductions in fuel consumption, but highest emissions. The arrangements with high-speed generators presented the lowest mass, volume and acquisition costs.

Abstract:

Some communities in Thailand located on Island with high wind velocities but an unreliable utility supply, will typically install diesel powered generators and wind generators to form a microgrid. Microgrid projects have been developed in many parts of the world, and commercial solutions have started to appear. Such systems face specific design issues, especially when the wind penetration is high enough to affect the operation of the diesel plant. The dynamic behavior of a medium penetration hybrid microgrid is investigated. It consists of a diesel generator set, a wind power generator and several loads. The diesel engine drives a 3x2,000 kW synchronous generator with excitation control. The wind turbine drives a 6x800 kW (full power converter) synchronous generator. The total load of the microgrid is about 4 MW which varies during the day. The excitation controller and speed controller for the diesel’s synchronous generator are designed, as well as the power control of the wind turbine. The system is modeled and simulated using software DIgSILENT PowerFactory. The study evaluates how the power generation is shared between the diesel generator set and the wind generator, the voltage regulation during load connections, and discusses the need of battery energy storage, the system ride-through-fault capability and frequency control. The results of several case studies are presented. The results have shown that the systems are stable under various ratio of PWIND / PLOAD from 10% to 100%, except ratio of PWIND / PLOAD from 110%.

Abstract:

For electrification of decentralized energy consumption facilities, as a rule, constructed an autonomous diesel power station, the operation of which involves the use of diesel fuel mainly to start the unit, and the rest of the time the diesel generator sets operate on treated oil. To reduce fuel consumption (treated oil) and reduce the load on diesel generators, it is proposed to use as the main power source for oil pumping stations, located in regions with high wind energy potential – an autonomous hybrid power-supply system – wind-diesel power station with a parallel operation of the wind and diesel power station. The article provides an operation scheme of a wind-diesel power station. In case when there is no possibility to place diesel generator sets of the equivalentcapacity in the powerhouse hall, then the article describes the optimal calculation algorithm for power distribution between diesel generator sets with different capacity, based on solving simultaneous equations by using the Lagrange multiplier method. The article also provides a practical example of the algorithm.

Abstract:

<abstract> Renewable energy has grown in popularity in recent years as a solution to combat the effects of pollution on the environment. The main purpose of this research is to design a microgrid system in Lakshadweep Island to determine the cost and dependability of a solar photovoltaic system that is combined with biomass, wind energy and diesel generator. Two types of hybrid systems like solar/biomass generator/wind turbine and Solar/diesel generator/biomass are investigated to get an optimal solution using HOMER Pro software. The hybrid microgrid system is optimized with low cost of energy (COE) and less environmental pollution. The reliability indice like unmet load is determined for each case to access the performance of the system. The influence of different Weibull shape parameter in solar/biomass generator/wind turbine hybrid system with sensitive variation of solar irradiation and wind speed are discussed. The scheduling of diesel generator in solar/diesel generator/biomass generator with various scenarios are analyzed based on minimum net present cost. The optimization results shows that the solar/diesel generator/biomass hybrid system has low net present cost of 432513 ＄ and cost of energy of 0.215 ＄/kWh as compared to solar/biomass/wind turbine for the selected site location. The proposed solar/diesel generator/biomass system produces emission of 7506 kg/yr. The emission produced in Lakshadweep Island using the proposed model is reduced since this Island currently produces electricity mainly with diesel generators. The optimal sizing of various components in microgrid system is performed to get the optimal solution. </abstract>

Abstract:

This study aims to analyze the amount of electric power and the profit achieved under the installation of the Photovoltaic array. Solar panel tested was laid on the surface of the Training Ship 02 Sultan Hasanuddin. The technical analysis, namely the calculation of electrical power and economical use of Solar-Powered Electric to support the diesel-powered electric generator as the main source of electrical power. A comparison of power was made by measuring the electric current and voltage variable as well as the financial calculation between the diesel-powered and solar-powered electric generator. The financial calculation was analyzed by using NPV, IRR and PI methods. The results showed that since the power capacity of the Solar Panels was almost similar to the capacity of the Diesel Generator with the output power assumed to be similar, the Solar Panel that supports the Diesel Generator was more profitable than the use of Diesel Generators without supporting solar cells.

Abstract:

Purpose: Development and approbation of the methodology of definition of energy expenses on excitation of traction generator of diesel locomotive on the stage of locomotive traction characteristic prediction. While definition of diesel power spent on traction generator excitation during prediction of traction-energy characteristics of diesel locomotive it’s necessary to consider current technical state of an exciter and traction synchronous generator. This task can be solved as a result of statistical analysis of information being registered by subsystem of board diagnostics of contemporary diesel locomotives. Methods: It’s used in the work the methods of preprocessor handling of information volume and statistical analysis of formed sampling. Results: There have been obtained the dependences allowing to predict with high precision the expenses of power for traction generator excitation in various work modes of diesel locomotive on the basis of preliminary analysis of data of board diagnostics subsystem. The necessity of such analysis is preconditioned by large scatter of parameters of magnetic system of traction synchronous generators and, hence, power values spent on their excitation which reaches 100% for generators 2TE116U at 40 kW power. Practical significance: The obtained results help to rise definition accuracy of traction-energy properties for particular locomotive.

Abstract:

In the article, using MatLab dynamic simulation modeling, a study was made of the excitation systems of powerful synchronous generators of stationary diesel generator sets, which are the main sources of emergency power supply for nuclear power plants. The optimal structural complexity mathematical model of a synchronous machine in relative units and orthogonal synchronous coordinate system is used. A comprehensive simulation of diesel generator sets was carried out with the reproduction of both the dynamics of the automatic control system for excitation of a synchronous generator and the diesel engine control system. The simulation takes into account the features of starting a diesel generator to accelerate a synchronous machine, its initial excitation from a battery. Particular emphasis is placed on the study of self-excitation modes through a transformer connected to the stator circuit of the generator and a thyristor rectifier with an excitation winding as a load, as well as parallel operation with the power system. As a result, the processes of starting a diesel generator set in idle mode, effective self-excitation, autonomous operation of the generator at idle, and applying a load to the generator up to the values of permissible overload were simulated. The work of all channels of the control system is shown, including the signals of the regulators of the automatic control system and mechanical variables that are inaccessible in practice. The adequacy of the developed model is proved by comparison with a real physical experiment when testing a diesel generator at a nuclear power plant. The possibility of using the model developed in MatLab as a virtual test site for testing a diesel generator set and a computer simulator for specialized engineering personnel of a nuclear power plant is demonstrated.

Abstract:

The power generation efficiency and power cost of an independent microgrid that distributes the power from a small diesel engine power generator was investigated using numerical analysis. The fuel consumption of a small diesel engine and the relation between power generation and heat power were obtained in experiments using a prototype. The independent microgrid built using one to six sets of 20 average houses in Sapporo and the distributed engine generators were examined using these test results. However, the operation of a diesel engine power generator controls the number of operations according to the magnitude of the power load of the microgrid. When a diesel engine power generator is distributed, since the power generation capacity per set decreases compared with the central system, the load factor of each engine generator rises. As a result, the operation of an engine at partial load with low efficiency can be reduced. When the number of distributions of the engine generator increases as a result of numerical analysis, the cost of the fuel decreases. However, when the rise in facility cost is taken into consideration, the number of engine generators for distribution is in fact 3 or 4.

Abstract:

Diesel Generator set was found to be a favorite power generator in a remote area. In this area, diesel genset usually consumes a significant amount of diesel fuel with higher fuel price than an urban area. Diesel Generator capacity conventionally prepared twice bigger or more than the existing load to prevent any load spike from designated equipment. This work implements an Energy Management System to cut the spike with the support from battery storage unit and photovoltaic module. Once the Energy Management System cut the load spike using battery/photovoltaics, Diesel Generator loads no longer need to be irrelevantly bigger than the existing load. The current experiment in the remote island at Raja Ampat archipelago indicates that the using of 80 kVA Diesel Generator can be reduced to 42 kVA Diesel Generator. This Diesel Generator replacement induces fuel consumption up to 50 %. With this designed work, a smart microgrid with PV-Battery-Diesel can be installed in a designated remote area with lower fuel consumption.

Abstract:

In the era of digital devices, many industries still use traditional methods of pen and paper to maintain records. One such industry is the diesel generator industry where these generators are operated without any proper supervision. The current management of these generator vans is highly unorganized. This causes a lot of miscommunication between the owners and the customers. The idea focuses on monitoring the different parameters of a diesel generator using internet-connected sensors. Parameters such as fuel consumption, AC power ON time, RPM of the turbine, and temperature are measured in real time. The system helps the owners to monitor their generators vans through one mobile application rather than depending on the on-site operators. Both the owners and customers can see how much power was consumed and how their bill was generated. Rather than using pen and paper to maintain records in the current method, the new system completely transforms the old methods into a highly digitalized modern business.

Abstract:

The article highlights an important scientific and technical problem: increasing the operation efficiency of the diesel generator power plants. One of the possible solutions of the problem is developing the diesel generators that operate in a variable speed mode with shared loads on the power plant. Introducing such diesel power plants into practice in recent decades has become possible due to the necessary converting semiconductor equipment, as well as a significant increase in prices for hydrocarbon fuels and objectively formulated requirements to improve the environmental performance of technical complexes. There is presented a comparative analysis of the energy efficiency of two power plants: with classic diesel generators and with a variable speed diesel generator. It has been proposed to compare the energy efficiency of the power plants by calculating the specific and absolute fuel consumption. The method of determining parameters of fuel consumption is considered. The method is based on using a multi-parameter characteristic of a diesel engine and the values of the efficiency ratios of the elements of the power equipment of plants. The results of calculating the specific fuel consumption of the power plants when changing the load power subject to the operating mode of the generators are presented. The results confirm the energy efficiency of the power plant with a variable speed diesel generator. Efficiency is increased due to saving the hydrocarbon fuels. The maximal savings correspond to the power plant operation under the load 20% less than the nominal.

Abstract:

Nigeria has a large number of remote areas that are not being electrified, this is because the power generated is less than the demand of the country. Garundole village is a typical example, with a population of about 270 is not connected to the main grid. Currently load shedding is being practiced by the Power Holding Company of Nigeria (PHCN) to dispatch the power being generated. Moreover, majority of the people leaving in these remote villages depend mostly on diesel power generator. Thus, there is a need to have an independent generating station for such kind of remote village to ease the living conditions of its inhabitants. This paper therefore, reports the economic assessment of PV/diesel/battery hybrid off-grid energy system as an alternative solution to these remote villages. In this regard, three different system configurations is being be studied and analyzed using HOMER optimization software to carry out the economic analysis of the systems and its technical feasibility. The systems include; standalone diesel generator, hybrid PV/diesel with battery storage and hybrid PV/diesel without battery storage. The result obtained from the study shows that a hybrid PV/diesel with a backup battery has the potential capabilities of replacing diesel powered generator used by individual households independently.

Currently load shedding is being practiced by the Power Holding Company of Nigeria (PHCN) to dispatch the power being generated. Moreover, majority of the people leaving in these remote villages depend mostly on diesel power generator. Thus, there is a need to have an independent generating station for such kind of remote village to ease the living conditions of its inhabitants. This paper therefore, reports the economic assessment of PV/diesel/battery hybrid off-grid energy system as an alternative solution to these remote villages. In this regard, three different system configurations is being be studied and analyzed using HOMER optimization software to carry out the economic analysis of the systems and its technical feasibility. The systems include; standalone diesel generator, hybrid PV/diesel with battery storage and hybrid PV/diesel without battery storage. The result obtained from the study shows that a hybrid PV/diesel with a backup battery has the potential capabilities of replacing diesel powered generator used by individual households independently.

Abstract:

Owing to the intermittent nature of renewable energy, microgrids in islanding operation mode require backup power sources. The diesel generator is the most popular backup source, but does not offer an instantaneous start-up and cannot immediately provide the necessary power. Therefore, supercapacitors are used to assist the power balance during diesel generator start-up thanks to their responsiveness and high-power density. This paper proposed a power management strategy for an autonomous DC microgrid based on a photovoltaic source, electrochemical storage, a supercapacitor, and a diesel generator. The proposed control system aimed at power balance while accounting for the slow start-up characteristic of the diesel generator, the self-discharge of the supercapacitor, the dynamic load management, and the economic operating mode of the diesel generator. The main contribution of this paper centered on a power management strategy solving the above issues integrally, and economic analysis for the diesel generator and microgrid. Experimental studies were carried out for different scenarios and the results obtained confirmed the effectiveness of the proposed strategy. Furthermore, the study provided a comparison between the economic operating and load-following modes of the diesel generator and demonstrated that the economic operating mode of the diesel generator can reduce the total energy cost of the DC microgrid.

Abstract:

Hybrid photovoltaic-diesel generator power system is important for rural electrification with the diesel generator supplying electricity when battery bank fails to meet the load demand. However, the operation of diesel generator could also be very costly due to high operation and maintenance cost when compared to photovoltaic-battery system. As a result, proper sizing must be conducted to determine the economic indicators of the hybrid photovoltaic-diesel generator system throughout its lifetime. This paper presents the design of such system for an island resort in Langkawi, Kedah, Malaysia. HOMER software was used to simulate the design parameters and economic performance of the system as compared to the existing diesel generator system. Apart from that, different capacities of PV array, battery bank and inverter were investigated in this study to determine the optimum configuration of these components such that the total cost of supplying the load demand at the resort could be minimized. The results showed that the hybrid photovoltaic-diesel generator system is more economically feasible than the existing diesel generator system used at the resort.

Abstract:

PT. X (nama disamarkan), merupakan suatu perusahaan yang bergerak di bidang industri. PT. X di-supply dengan listrik tegangan menengah yaitu 20 KV yang berlangganan premium dari PLN (Perusahaan Listrik Negara) sehingga diberikan keunggulan berupa keandalan pasokan listrik yang lebih baik. Dengan demikian, risiko adanya pemadaman listrik sangat minim sehingga membuat diesel generator sebagai sistem backup tenaga listrik jarang digunakan. Hal ini berpotensi dapat menyebabkan performa diesel generator menurun, bahkan dapat mengalami kerusakan. Untuk itu diperlukan pemanasan diesel generator secara rutin menggunakan beban tiruan berupa heater dengan nilai beban yang dapat diatur secara bertahap sesuai kebutuhan. Pemanasan genset setidaknya seminggu sekali selama minimal 10 menit. Namun pada praktiknya pemanasan diesel generator pada PT.X dilakukan setiap 10 hari sekali dengan durasi pemanasan sekitar 30 menit. Meskipun pada saat pemanasan semua diesel dioperasikan, namun hanya 2 buah diesel saja yang dilakukan pengecekan. Hasil dari pemanasan ini adalah kemampuan diesel generator dalam mem-backup tenaga listrik selama blackout dengat cukup baik. Namun pemeliharaan yang selama ini dilakukan dinilai tidak optimal. Hal ini dikarenakan kemampuan diesel generator tidak dimaksimalkan, namun hanya seperempat dari kemampuannya.

Abstract:

This paper presents a method for determining optimal sizes of PV array, wind turbine, diesel generator, and storage battery installed in a building integrated system. The objective of the proposed optimization is to design the system that can supply a building load demand at minimum cost and maximum availability. The mathematical models for the system components as well as meteorological variables such as solar energy, temperature, and wind speed are employed for this purpose. Moreover, the results showed that the optimum sizing ratios (the daily energy generated by the source to the daily energy demand) for the PV array, wind turbine, diesel generator, and battery for a system located in Sohar, Oman, are 0.737, 0.46, 0.22, and 0.17, respectively. A case study represented by a system consisting of 30 kWp PV array (36%), 18 kWp wind farm (55%), and 5 kVA diesel generator (9%) is presented. This system is supposed to power a 200 kWh/day load demand. It is found that the generated energy share of the PV array, wind farm, and diesel generator is 36%, 55%, and 9%, respectively, while the cost of energy is 0.17 USD/kWh.

Abstract:

As the global diesel generator market grows and generators gain wider use, various methods are being developed to increase their energy efficiency. One of these methods entails integrating a Li-ion battery with diesel generators (DGs). This method did not attract attention until recently because it was economically unappealing. A significant decrease in the price of Li-ion batteries in recent years has made hybrid diesel generator/Li-ion battery systems more viable. We present a model-based economic analysis of a hybrid DG/Li-ion battery system with the aim of increasing the energy efficiency of diesel power generators. Special blocks were developed for calculations and comparisons with a MATLAB Simulink model, including 457 kW DG operating modes with/without a Li-ion battery. We simulated the system in order to calculate the conditions required to achieve savings in fuel and the level of savings, in addition to the payback time of the Li-ion battery. Furthermore, we present the additional savings gained by postponing the investment in a new diesel generator thanks to the Li-ion battery. Based on our findings, the payback period of the Li-ion battery system varies between 2.5 and 4 years. According to our 12-year economic analysis, the cost savings resulting from postponing new investments can reach 40% of the profit gained from the savings during such a period.

Abstract:

Isolated communities are progressively integrating renewable generation to reduce the societal, economic and ecological cost of diesel generation. Unfortunately, as renewable penetration and load variability increase, systems require greater diesel generation reserves, constraining renewable utilisation. Improved diesel generator flexibility can reduce the requirement for diesel reserves, allowing increased renewable hosting. Regrettably, it is uncommon for utilities to modify diesel generator control during the integration of renewable source generation. Identifying diesel generator flexibility and co-ordination as an essential component to optimising system hosting capacity, this paper investigates improved diesel generator flexibility and coordination via low-load diesel application. Case study comparisons for both high- and low-penetration hybrid diesel power systems are presented in King Island, Australia, and Moloka`i, Hawai`i, respectively. For King Island, the approach details a 50% reduction in storage requirement, while for Moloka`i the application supports a 27% increase in renewable hosting capacity.

Abstract:

The electronic speed governor plays an important role in diesel generator sets. The ideal method for developing and debugging the electronic governor is to simulate the diesel engine’s dynamic characteristics with the hardware-in-the-loop simulation system. In this system, the diesel engine can be replaced by a mathematical model. Our research proposed a novel diesel engine modeling method using the long short-term memory neural network for simulating dynamic characteristics of the rotational speed of diesel generator sets. The proposed model is trained and tested on the data of the real diesel generator sets. With different power loads and unloads, experimental results demonstrated that this method was able to successfully simulate the dynamic characteristics of diesel generator sets. In addition, comparing to other existing methods provided a conclusion that the performance of the model was better than others. Finally, the proposed model was deployed on an established hardware-in-the-loop simulation system. The results further demonstrated that this model was able to reproduce the diesel generator sets’ dynamic characteristics.

Abstract:

The advancement in the Internet of Things (IoT) has made an application in all areas. Presently, IoT is causing ripples in the automation of devices. The rampant energy crisis made it necessary to control alternative electricity sources such as electrical generators. An electrical generator is a piece of handy equipment when it comes to power shortages. They are reliable but require human intervention to keep them from opportunity to time. The framework presented in this work changes the manual Monitoring of generators to auto-monitoring. An embedded system monitors various activities when the generator is up and running, including status and alarms for multiple scenarios. This paper addresses issues recently raised that only hint at greater challenges in this domain. To make things easier to handle in operating and Monitoring of generator, an IoT-based android application is designed that provides status update information about the generator when it is operational. The embedded system uses sensors that provide up-to-date information on fuel, oil, temperature, flow, and voltage and delivers that information to the person responsible for handling these issues. The embedded system is based on a small, scaled Arduino controller, which generates results in its propelled condition and then sends the information to an android device to monitor the generator status in real-time.

Based on a mathematic model of diesel generator mechanical centrifugal governor and the traditional PID control and fuzzy control, a fuzzy PID controller is designed so as to accomplish the self-adjustment of diesel generator mechanical governor parameters. The fuzzy PID controlling diesel generator mechanical governing system is simulated by Simulink and the simulation results suggest that the fuzzy self-adjusting PID control owns the merits of well dynamic property, strong robustness and better adaptability compared to the traditional PID control. Therefore, the performance of diesel generator rotate speed governing system is largely advanced.

Abstract:

The measurements of oil properties of crude Jatropha oil and its blends of 10%, 20%, 30%, 40%, and 50% with diesel fuel have been carried out in this study. Our results suggested that the viscosities of crude Jatropha oil (CJO) blends decrease gradually with increasing temperatures, but they increase gradually with rising ratio of crude Jatropha oil compared to those of diesel fuel. Analysis of physical properties suggested that cold filter plugging point, calorific value, gravity and cetane index decrease gradually with rising percentages of crude Jatropha oil, but the flash point and mid boiling point increase gradually compared to those of diesel fuel. In this study, the prepared oil blends are applied to a power generator for a real application test. Results of electricity generation suggested that crude Jatropha oil blends may be used as an alternative fuel compared to that of diesel fuel. Results of gas emissions in a power generator suggested that CO, CO2 and NOX emissions from crude Jatropha oil blends are lower, but O2 emissions are higher compared to those of diese fuels.

Bangladesh is a land of rivers, canals, and lakes where water transportation is an essential means of transport. The country use boats as one of the leading resources of a carrier in its widespread inland waterways. Most of the currently used boats use only diesel for fuel. Appropriate use of renewable energy sources, particularly solar energy with diesel generators, could reduce diesel consumption. In this paper, a typical boat energy requirement was calculated to be 42.10 kWh/day. A boat could be driven by a DC motor using electrical power generated using an onboard PV system, battery, and a small generator. The carrying capacity of the vessel is 20passenger for 8hours a day. The designed system consists of a 10.6 kW PV, 1.6kW rated small gas generator, onboard battery storage consists of 16 batteries, each placed 6V, 333 Ah, and a 48 V DC motor rated 5 kW 3000 rpm with a speed controller.

Abstract:

In the context of electricity production in remote areas, the use of diesel generators, either alone or in hybridization with renewable energy sources, faces many technical problems. Indeed, the electrical instability that often characterizes the isolated networks, due to the fluctuating character of renewable resources and the high variability in the load profile, leads to the operation of the diesel generator in transient dynamic conditions, at low loads or outside prescribed environmental conditions. Furthermore, the extended operation of the diesel generator at low charge results in the condensation of combustion residues on the engine cylinder walls, which, after a certain time, increases friction, reduces the efficiency and increases fuel consumption. One way to solve this problem and to eliminate these deposits is to operate the engine at a higher speed until the operating temperature is reached. This paper explores the impact of the wind turbine penetration rate for hybrid wind–diesel systems and the effects of cold temperatures, high altitude, and other environmental operation conditions on diesel generators’ performances. We outlines the impacts of low load and environmental conditions such as ambient temperature, humidity, moisture, abrasive dust, cold and corrosive environments on the operation of modern diesel generators. The problem has been approached by examining the existing literature, researching damage cases, analyzing existing data, and assessing industrial experiences.

However it is required the best system design that complies with the real site conditions which is very different from site to site. The differences are not only the incoming solar radiation but also, the availability of open land for locating the arrays, the conditions of existing diesel engine, and load profile. The goal of the PV-diesel hybrid system is reducing the diesel operation hours but delivering the electricity for 24 hours to the customers.

Abstract:

A substantial share of the electric energy is generated with synchronous generators that provide sustained alternating current (AC) voltage and frequency energy to regional and national power systems, which subsequently transport and distribute it to diverse users. In an attempt to reduce environmental effects, electric energy markets have recently become more open, resulting in more flexible distributed electric power systems. In such distributed systems, stability, quick and efficient delivery, and control of electric power require some degree of power electronics control to allow for lower power in the electric generators to tap the primary fuel energy potential better and increase efficiency and stability. This is how variable-speed electric generators (VSEG) recently came into play, up to the 400-megavolt ampere (MVA)/ unit size, and which have been at work since 1996. This paper provides coverage of variable-speed electric diesel generators (VSDEG) in distributed generation and their impacts on fuel efficiency and greenhouse gases (GHG). It discusses permanent-magnet-(PM) synchronous generators, solutions based on power electronics such as diesel-driven wound-rotor-induction generator, doubly-fed-induction generator (DFIG), rotating stator generator, and the application of continuously variable transmission to a VSEG. The benefits and limitations of the selected technologies are also presented. The list of references given at the end of the paper should offer aids for students and researchers working in this field.

Abstract:

Renewable energies are the best solutions to reduce CO2 emissions and supply reliable electricity. This study aims to find the best combination of various components considering economic, environmental, and technical factors together. The most important consideration factors are the limitation of using PV panels due to the land constraints and applying CO2 penalties where diesel generators and the grid are generating electricity. Findings show that providing electricity by hybrid systems would be useful even in the well-provided electricity regions by the grid with the least blackouts. The best combination of the proposed components, including PV, bio generator, diesel generator, batteries, and grid for the case study region where the load demand is 890 kWh/day and peak load is 167.2 kW, would be an off-grid hybrid system including PV, bio generator, diesel generator, and battery. The optimization results show an NPC (present value of the costs of investment and operation of a system over its lifetime) of $1.02 million and a COE (the average cost per capital of useful electricity produced by the system) of 0.188 $/kWh. Finally, due to the showing of the effect of different conditions on the optimization results and making the study usable for other circumstances of the case study region, some sensitivity analyses have been carried out.

Abstract:

This paper presents an optimized energy system model for a small locality in Kutubdia Island, Bangladesh at latitude of 21.82 °N, longitude of 91.86 °E. This isolated island is located at the southern coast of Bangladesh, separated from the main land by the Kutubdia channel. At present, grid connection from the mainland is not present and is not planned in the near future. The proposed energy system comprises Solar PV, Wind turbines, Biogas generators for power generation whereas a diesel generator has been used as backup power supply and batteries have been considered to facilitate energy storage. Hybrid Optimization Model for Electric Renewable (HOMER) has been used to obtain an optimized system comprising all the renewable energy resources present. The designed energy system consists of 28 kW Solar PV panels, 30 kW Wind Turbines, 8 kW Biogas Generator, 9 kW Diesel Generator. The system generates electricity with a renewable fraction of 97%. The cost of electricity has been estimated as US$ 0.42/kWh considering 10% Rate of Return with an initial capital cost of US$ 199,541.

Abstract:

This study investigates the technical and cost-effective performance of options renewable energy sources to develop a green off-grid telecommunication tower to replace diesel generators in Malaysia. For this purpose, the solar, wind, pico-hydro energy, along with diesel generators, were examined to compare. In addition, the modeling of hybrid powering systems was conducted using hybrid optimization model for energy (HOMER) simulation based on techno-economic analysis to determine the optimal economically feasible system. The optimization findings showed that the hybrid high-efficiency fixed photovoltaic (PV) system with battery followed by 2 kW pico-hydropower and battery are the optimal configurations for powering off-grid telecommunication towers in Malaysia with the lowest net present cost (NPC) and cost of energy (COE). These costs of NPC and COE are more down than diesel generator costs with battery by 17.45%, 16.45%, 15.9%, and 15.5%, respectively. Furthermore, the economic evaluation of the high-efficiency solar fixed PV panels system annual cash flow compared to the diesel generator with the battery system indicated a ten-year payback period.

Abstract:

Telecommunication network nodes located at very hostile environments require, among other rigorous demands, highly reliable backup power supplies. Current solutions, which are mostly based on diesel generators, have several drawbacks such as unreliable start of a diesel generator at low temperatures, maintenance of the generator due to rotary parts, and the pollution of the environment which is caused by exhaustive fumes from a diesel engine. This paper proposes the implementation of backup power supply based on proton exchange membrane (PEM) fuel cell and solar panel. In addition, it is also depicted the implementation of high-efficiency boost converter which provides adequate supply voltage for telecommunication devices. The benefits of the proposed solution are improved energy utilization, decreased need for maintenance and zero emission.

Abstract:

Due to unreliability of power supply from national grid, high cost of diesel and maintenance of generators being an alternate for national grid, there is need to adopt a renewable energy source for efficient and reliable power supply. Savings associated with conversion of a stand-alone diesel generator powered system to a reliable PV/Diesel hybrid power system with energy storage in batteries for Bayero University Kano Library using HOMER software was presented in this study. The economic parameter of merit used in selecting an optimum energy system from set of configurations was total Net Present Cost (NPC) in billions of naira. Generator + PV + Battery system has a total NPC of (₦ 1.17B) and saves (₦ 0.9B), Generator + PV system has a total NPC of (₦ 1.68B) and saves (₦0.4B), Generator + Battery system has a total NPC of (₦ 2.05B) and saves (₦ 0.03B), PV + Battery system has a total NPC of (₦ 2.28B) and saves (₦ - 0.2B) when all compared with Generator-only system (₦ 2.08B). It can be seen that the best case is the PV + Gen + Battery system. Even though it has the highest capital cost, but it resulted to the least net present cost (NPC); as such, PV + Gen + Battery system is the optimized model to fulfill the load demands. Therefore, this research work shows that the integration of PV with battery storage into the existing diesel stand-alone system in the University library is more reliable at the lowest lifecycle cost.
