Full textAbstract:
In traction power supply systems for city electric transport without storage devices, a significant part of the recovery energy is usefully reused for the load in the process of inter-train flows along the contact network. The excess part of the recuperation is dissipated by heat in the braking resistors. The use of on-board storage devices makes it possible to redirect all recovery energy from the car's traction drive to them. The remaining amount of no more than two-thirds of the received recuperation energy is supplied back to the traction drive from the storage device, excluding internal losses, since due to ohmic resistance, the actual efficiency of any type of storage device does not exceed 64 %. The on-board storage device consumes a significant amount of paid energy from the traction substation for its transportation by car, compensation for self-discharge, etc. The total balance of recovery energy returned to traction and losses from additional energy consumption for on-board storage devices is negative. When stationary storage devices operate in the contact network, useful recuperation flows are completely preserved. The excess part of the recovery is redirected to the contact network, where one part of it powers a low-power non-traction load while charging the storage device, and the other goes to the storage device, charging it. After a short period of storage in the storage device, the remainder of the excess recovery is released into the network for the load that appears in it. A stationary storage device has no energy consumption for transportation, and the consumption of paid energy for its own needs and compensation for self-discharge is significantly less than that of an on-board storage device due to its higher load factor. The stationary storage device has a positive balance of recovery energy which allows additional savings of paid energy from the traction substation in the amount of up to 10 % relative to such consumption during useful recovery flows without the use of storage devices.

Wind energy could be generated and captured with a storage device within the customer premises for local utilization and for the provision of various services across the electricity supply chain. To assess the benefits of adding a storage device to an electricity distribution network that has two wind turbines with a base load of 500 kW and a typical peak load under 1500 kW, a 2 MW/4 MWh storage is installed. To observe the effects of adding the storage device to the network, a technical analysis is performed using the NEPLAN 360 modelling tool while an economic analysis is carried out by estimating the likely payback period on investment. A storage potential benefit analysis suggests how changes in integration policies could affect the utility of adding the storage device. With the addition of the storage device, self-consumption of wind energy increased by almost 10%. The profitability of the project increased when the device is also deployed to provide stacked services across the electricity supply chain. Policies that permit the integration of devices into the grid could increase the profitability of storage projects.

Full textAbstract:
In the context of energy transformation, the importance of energy storage devices in regional integrated energy systems (RIESs) is becoming increasingly prominent. To explore the impact of energy storage devices on the design and operation of RIESs, this paper first establishes a bi-level dynamic optimization model with the total system cost as the optimization objective. The optimization model is used to optimize the design of three RIESs with different energy storage devices, including System 1 without an energy storage device, System 2 with a thermal energy storage (TES) device, and System 3 with TES and electrical energy storage (EES) devices. According to the design and operation results, the impact of energy storage devices on the operational performance of RIESs is analyzed. The results show that under the design conditions, energy storage devices can significantly increase the capacity of the combined heating and power units and absorption chillers in System 2 and System 3 and reduce the capacity of the ground source heat pumps and gas boilers; the impact of the TES device on System 3 is more significant. Affected by systems’ configuration, the operating cost, carbon tax, and total cost of System 2 are reduced by 2.9%, 5.5%, and 1.5% compared with System 1, respectively. The EES device can more significantly reduce the operating cost of System 3, with a reduced rate of 5.7% compared with that in System 1. However, the higher equipment cost makes the total cost reduction rate of System 3 less than that of System 1, which is 1.75%. Similar to the design conditions, under the operation conditions, the TES device can effectively reduce the carbon tax, operating cost, and total cost of System 2, while System 3 with an EES device can significantly reduce its operating cost regardless of whether the energy price changes or not. To some extent, this study systematically elucidated the impact of TES and EES devices on the optimal design and operation performance of RIESs and provided a certain reference for the configuration of energy storage devices.

Full textAbstract:
Monolithic self-charging storage device with Stable 3 V Operation The energy paradigm has been changing from the traditional power plant system to micro-gride system based on renewable energy. However, renewable energy including wind, solar, and vibration, is intermittent and influenced by time, weather, and location. Thus, the suitable storage device is required for efficient utilization of renewable energy. The representative combination of renewable energy and energy storage device is an energy storage system (EES) consisting of photovoltaic systems and Lithium-ion batteries. The EES is mainly applied to social infrastructure system that generate large amounts of energy. As the Fourth Industrial Revolution progresses, the rechargeable power supply including Lithium-ion batteries is widely applied to wireless system such as sensor network, wearable device, and electric vehicles. However, the batteries have only storage function, so periodic charging is required. Thus, it is necessary to develop technologies for portable and small energy generation/storage as standalone power sources that can continuously supply power to various electronic devices. Large-scale energy production/storage system has entered the maturity stage, but the development of portable and small energy generation/storage systems based on IoT is in its early stages. To date, research on this system is conducted by simply connecting energy harvesting and energy storage device to external wires after manufacturing them independently. However, the introduction of additional wires is complicated in system design and manufacturing and has difficulty in miniaturization. These problems have motivated the integration of both functions into one device. The integrated device is fabricated by sharing one electrode, called a common electrode between the energy harvesting and storage components. Currently, research on a monolithic photo-charging storage device that integrates solar cells and energy storage devices into one device has been developed. This structure can miniaturization and flexible design, thereby it is suitable for the wearable and smart device. Although the importance of an integrated device is emphasized, the current research of monolithic device is limited to the fabrication of an integrated device without considering their practicability. In other words, most studies focus on simply connecting two devices to achieve the highest overall efficiency. In this case, since the open circuit voltage of single solar cell is under 1 V, the operation of photo-charging storage device is limited to 1 V. Thus, we proposed the monolithic photo-charging storage device operating at 3 V. We fabricated the multiple series-connected perovskite solar cell to increase the operating voltage. Since the secondary batteries are difficult to be charged by the high current density of 20 mA cm−2 solar cell owing to their storage mechanism, we choose the supercapacitor with the rapid response to an applied electric field change. We select the silver paste as the common electrode owing to its strong adhesion, high electric conductivity, and lack of chemical/mechanical damage to the solar cell and supercapacitor. Based on density functional theory (DFT) calculation, we prove the common electrode exhibits good compatibility with our supercapacitor and solar cell. For this reason, the proposed photo-charging storage device exhibits an ultra-fast charging time of less than 3 sec under AM 1.5 G illumination and high overall efficiency of 13.17 % at 1 mA cm−2 and 9.87 % at 20 mA cm−2. For electric double layer supercapacitors integrated with a solar cell, higher discharging current densities that 20 mA cm−2 have not been reported so far. We firstly demonstrate the behavior of photo-charging storage device under light/dark state by the impedance analysis. By the impedance analysis, we demonstrated that the solar cell provides a stable power supply to the supercapacitor under light condition. Further, the additional encapsulation ensures the long-term stability of photo-charging storage device and demonstrate the indoor cycling performance. We prove the photo-charging storage device has high potential as an IoT sensor power source. Figure 1

Due to the broad application prospect, flexible and transparent electronic device has been widely used in portable wearable devices, energy storage smart window and other fields, which owns many advantages such as portable, foldable, small-quality, low-cost, good transparency, high performance and so on. All these electronic devices are inseparable from the support of energy storage device. Energy storage device, like lithium-ion battery and super capacitor, also require strict flexibility and transparency as the energy supply equipment of electronic devices. Here, we demonstrate the development and applications of flexible and transparent lithium-ion battery and super capacitor. In particular, carbon nanomaterials are widely used in flexible and transparent electronic device, due to their excellent optical and electrical properties and good mechanical properties. For example, carbon nanotubes with high electrical conductivity and low density have been widely reported by researchers. Otherwise, graphene as an emerging two-dimensional material with electrical conductivity and carrier mobility attracts comparatively more attention than that of other carbon nanomaterials. Substantial effort has been put on the research for graphene-based energy storage system by researchers from all over the world. But, there is still a long way to accomplish this goal of improving the performance for stretchable and transparent electronic device due to the existing technical conditions.

Full textAbstract:
This study represents effects of an elastic support on the power generation and storage capability of piezoelectric energy harvesting devices. The governing equations were derived and solved for a piezoelectric energy harvesting device made of elastic support, multilayer piezoelectric beam, and a proof mass at its free end. Furthermore, a Thevenin model for a rechargeable battery was considered for storage of the produced power of the piezoelectric energy harvesting device. Analyzing the time-domain and frequency-domain responses of the piezoelectric energy harvesting device on an elastic support shows that the elastic deformation of the support significantly reduces the power generation and storage capability of the device. It was also found that the power generation and storage capability of the piezoelectric energy harvesting device can be enhanced by choosing appropriate physical parameters of the piezoelectric beam even if the elastic properties of the support are poor relative to elastic properties of the piezoelectric beam. These results provide an insightful understanding for designing and material selection for the support in order to reach the highest possible power generation and storage capability for piezoelectric energy harvesting devices.

The article analyzes the possibilities of using wind energy in Uzbekistan and studies the possibility of using energy storage devices to build a reliable electricity supply in the regions. In areas with weak winds, a device that first stores wind energy and then generates alternating electricity has been proposed. Energy storage systems have been analyzed, and it is recommended to use mechanical energy storage systems in the energy system consisting of renewable energy sources in the Republic of Uzbekistan. It has been noted that the use of such devices is particularly effective in areas far from centralized power supply, where power supply is not available or where reliability is low. An experimental model of a mechanical energy storage device using an elastic cord braid in a storage system and some equations for its design are given. The possibility and necessity of using this storage system is highly valued in our country. Despite the low power of the original model of the device, it is possible to achieve high results in the future by conducting research in this area and changing the type and composition of the elastic cord. This article presents the results of preliminary research on the development of a new design of mechanical energy storage devices using mechanical elastic cord.

Full textAbstract:
The application of capacitive energy storage devices in the electric starting systems for automobile internal combustion engines is considered, when instead of a standard battery, a battery of a smaller capacity is used, and in the remainder of the standard battery volume, the energy storage device is mounted. In this case, at the high specific indicators of the energy storage device, the reliability of the engine start can be increased with the same total volume and mass of the electric starting systems at low temperatures. The paper presents a methodology for a determination the parameters of the battery and the energy storage device which are connected in parallel for the electric starting systems, in the case when the type of internal combustion engine and its main parameters are specified, as well as the type of the starter motor and its characteristics. The conducted theoretical investigations made it possible to obtain the dependence of the required mechanical energy for starting the internal combustion engine from the value of the capacity of the energy storage device, as a result of which the required capacity of the energy storage device and its internal resistance, its initial energy, as well as its necessary volume and mass are determined. The volume and mass of battery can be determined from the reference literature or under certain methods for the specific energy of battery by volume and mass. If the ratio of the total volume of the battery and the energy storage device to the volume of the battery is less than unity, then at the given starting frequency of rotation, the usage of the energy storage device is reasonable, due to the reduction of the total volume of the electric starting systems. Similar calculations are conducted for other values of the average starting frequency of rotation. The optimal parameters of the battery and the energy storage device are in which the total volume will be minimal. The parameters of the electric starting systems with the energy storage device and the battery for the VAZ automobile engine with M6z/10G1 engine oil were calculated at a temperature of -20°C with a starter 35.3708 and the gear ratio of the drive gear 11,62. The results of the calculations are shown that for a specific energy of the energy storage device 1 Jcm3 at all starting rotational speeds, the usage of the energy storage device does not allow to reduce the total volume of the energy storage device and the battery in comparison with the volume of the battery required for scrolling the internal combustion engine shaft with this starting frequency.

Purpose. The main purpose of our work is to develop a method of rational control of dynamic operation modes of electrochemical energy storage devices to increase the efficiency of their operation as part of the energy supply systems of vehicles. Methodology. The authors reviewed the world literature on the topic of the work. The existing control methods of electrochemical energy storage devices were systematized and classified. Peculiarities and possibilities of their application taking into account the specifics of operation on vehicles, which are characterized by dynamic modes with unpredictable changes in the energy balance due to uncontrolled undercharges and overcharges were taken into account. The analysis of existing control methods showed that their common disadvantage is the use as information parameters to control and manage the operation modes of storage device, such as voltage and operating current, the values of which do not correspond to the current energy state of the device due to the fleeting nature of transient electrochemical processes in the device during operation in dynamic modes. The conclusion is made about the need to take into account the energy parameters of storage devices in the process of managing dynamic modes, which most fully and objectively reflect their performance. The advantage of pulse control methods of storage devices in dynamic modes of operation over DC methods is shown. Findings. The authors substantiated and experimentally confirmed the versatility of the developed galvanostatic method, which allows simultaneous control of the current energy state of the storage device and operational management of dynamic modes of its operation using a common criterion of control and management – the utilization factor of active materials, the information equivalent of which is the value of the area under the depolarization curve on the response signal of the device to the test pulse. Originality. For the first time it is proposed to combine the functions of control of the current energy state of the storage device and operational management of the dynamic modes of its operation with the use of the utilization factor of active materials. Practical value. The obtained results can be used to ensure the optimal operation mode of energy storage in the power supply systems of vehicles.

Full textAbstract:
The introduction of an energy storage system plays a vital role in the integration of renewable energy by keeping a stable operation and enhancing the flexibility of the power flow system, especially for an islanding microgrid which is not tied to a grid and for a self-contained microgrid which tries to stay independent from a grid as much as possible. To accommodate the effects of power fluctuations of distributed energy resources and power loads on power systems, a power flow assignment under power balance constraint is essential. However, due to power limitations of power devices, the capacity of storage devices, and power flow connections, the power balance may not be achieved. In this paper, we proposed a system characterization which describes the relation among power generators, power loads, power storage devices, and connections that must be satisfied for a system to operate by keeping SOC limitations of power storage devices. When we consider one power generator, one power load, and one power storage device connected at a single node, the generated energy by the generator minus the consumed energy by the load from some start time will increase/decrease the state of charge (SOC) for the storage device; hence, keeping SOC max/min limitations relies on whether the difference between the generated energy and the consumed energy stays within a certain range or not, which can be computed from the capacity Ess and other parameters. Our contribution in this paper is an extension and generalization of this observation to a system that consists of multiple fluctuating power generators, multiple fluctuating power loads, multiple storage devices, and connections that may not be a full connection between all devices. By carefully enumerating the connection-dependent flow paths of generated energy along the flow direction from generators to storages and loads, and enumerating the connection-dependent flow paths of consumed energy along the counter-flow direction from loads to storages and generators, we have formulated the increase/decrease of SOCs of storage devices caused by the imbalance between generated energy and consumed energy. Finally, considering the max/min limitations of SOCs and fluctuations of power generators and power loads, the conditions that the power generators and the power loads must have for SOCs of storage devices to maintain individual max/min limitations have been derived. The system characterization provides guidelines for a power flow system that can continue safe operation in the presence of power fluctuations. That is, in order for a system to have a feasible power flow assignment, there are the issues of how large the capacity of a power storage device should be, how large/small the maximum/minimum power/demand levels of the power generators and the power loads should be, and how the connection should be configured. Several examples using our system characterization are demonstrated to show the possible applications of our results.

Solar conversion devices are generally connected with energy storage systems to overcome the influence of sunlight variability. Developing an integrated solar energy conversion and storage device is an attractive approach to compensate for the energy loss of directly connecting these separate devices. In this work, a photocapacitive device is developed based on the Cu2O/CuO heterostructure, with Cu2O as a light absorber and CuO providing a platform for electron and ion storage. The coupling of Cu2O and CuO leads to a high specific capacitance of 135 mF/cm2 under bias and an open-circuit potential of 0.62 VRHE. A photo-charge and dark-discharge ability of Cu2O/CuO system under zero-bias is also discovered and explained based on the concept of Faradaic junction. This work presents an avenue for the investigation of high-performance Cu2O-based solar energy storage devices.

There are many mechanical and/or electrical energy storage devices nowadays which can be mounted on standard bicycles. The current trend regarding bicycle energy storage devices is to develop and improve electrical and electronic systems that can ease transportation. However, this paper shows the design process of a purely mechanical energy storage device, with no electrical components, which instead aims to entertain the user, producing a stimulus related to speed and physical exertion. The mechanical device has been designed according to an aspect or fashion known as steampunk, so that the mechanical elements forming the device (springs and spur gears) are visible to the user. The storage and discharge of energy are only produced by the user. In order to charge the device, after reaching an appropriate speed, the user uses the pedals in reverse motion. Alternatively, the mechanism can also be charged with a controlled braking system by actuating on a crank. The design process was based on the total design of Pugh and the AHP and QFD techniques.

Recent prosperity of artificial intelligence is undoubtedly making global data increase at a phenomenal rate. This obviously poses more stringent requirements on current storage devices. Unfortunately, considerable effort is only devoted to the development of on-chip storage device, while off-chip storage technology, particularly for archival storage device, remains slowly progressed. To further innovate the archival storage device, and thus revive its market, we here proposed a novel concept of an archival storage device based on scanning nanoprobe and oxygenated amorphous carbon having metal nanoclusters. A comprehensive numerical model was developed to mimic the write and readout performances of such archival storage device. It was found that the introduction of metal nanoclusters induced much stronger electric field inside the amorphous carbon layer than the case without metal nanoclusters. This beneficially facilitated the growth of conductive filament along metal nanoclusters, and the feasibility of using the proposed device to achieve an areal density of terabit per-square-inch area density, a write energy of picojoule energy per bit, and a switching speed of tens of nanoseconds, was demonstrated.

With demand for the natural resources exceeds a certain threshold, it leads to a global ecological threat like the “Amphhan” catastrophe that had ravaged the eastern part of West Bengal during the month of February 2020 that resulted in the loss of lives and economic activity which is yet to be regained with its earlier momentum. The inflicted calamity has given a “blow” as well as “boost” to renewable energy sector that leads to greater seriousness on development of the energy storages devices/stations in the country. While India has already achieved 374 GW of total installed capacity of power generation in which the contribution from the thermal sector is about 62 per cent and that of the RP is about 22 per cent that comes to 90 GW as of today and 60 GW is under pipeline or under construction or under tendering process. The year 2020 is undoubtedly a year of change and the COVID-19 pandemic situation together with enforced lockdown in several parts of the country and even in globe has forced people to think differently to remain relevant against the New-Normal. In order to choose the sources of energy that does not cause pollution to the surrounding environment, the RET is the best and most favourable options to opt for along with the battery storage devices for making the power available throughout the day-long and even when the sun sets. Most of the batteries currently produced and used in our country is lithium-ion based and is mostly imported. To be on the self-reliant mode and moving towards “Atmanirbhar Bharat” through “Make in India” we need to have more and more indigenous manufacturer of Li-ion batteries. Good news is that 10 Indian companies have already procured manufacturing technology from DRDO and large scale production of indigenous Li-ion batteries is expected soon. The National Energy Mission of the Government of India has just rolled out with a focus on the Make in India and is envisioned to take all necessary formalities and policy decisions to be adopted to incentivise advanced energy storage manufacturing in India through the application of innovation and new technology options that are available. As a science communicator, the authors strongly opine that with the appropriate support from the Government of India through the policy decisions by the Niti Aayog, India will be one of the top markets for the energy storage adoptions and manufacturing and is another way forward to mitigate the climate change by producing electricity free from carbon dioxide emissions into atmosphere and provide green energy for sustainable path of development. As we see that the energy storage is a new thrust area along with introduction of FGD technology retrofitting with the thermal power plant, we look forward to the new ecosystem to be achieved by 2030.

The possibility of integrating storage devices with renewable energy sources is being considered. The analysis of the averaged load schedules for the winter and summer periods is performed; the feasibility of using the drive to smooth out the peaks of the consumption load schedules is justified. A schematic solution for connecting an electric power storage device with a control system for a medium-voltage power supply network is proposed. The connection of the drive in such a system is provided on the 0.4 kV side using converter devices. The using of an AC-DC converter with a control system in such a system regulates the flows of active power in order to perform a two-way energy conversion in the case of energy accumulation by the storage device and energy return to the network.

Abstract We evaluate the storage performance of an integrated energy harvesting and storage system using a thermoelectric generator (TEG) and an organic energy storage device. The power generated by the TEG is obtained by varying the temperature of the heat source on the bottom surface of the TEG while keeping the opposite surface at a constant cooling temperature. The difference in temperature gradient (Δ T) increases the power generated by the TEG. Capacitance-voltage measurements were performed on the organic storage device to evaluate the storage capabilities of the embedded storage elements, CdS nanoparticles. The objective is to assess the possibility of the integrated system and evaluate the effectiveness of the storage device. Voltage, current and power density values are determined and compared for different load resistance. The results revealed that for the 100 Ω load resistor, the voltage across the capacitor was the maximum at a lower temperature gradient with a charge density of $5.14 \times 10^{-3} \frac{C}{m^2}$.

Promoting the use of solar energy resources has always involved the challenges of instability and supply–demand mismatch. The key to solving these issues is to efficiently store and utilize solar energy resources using high-performance heat storage devices. This study designed a high-performance shell-and-tube phase-change thermal storage device and established a numerical model using ANSYS software to summarize the device’s dynamic melting law. To verify the accuracy of the numerical simulation, a performance testing platform for the phase-change thermal storage device was built to investigate the impact of various factors, such as the inlet water temperature, inlet water flow rate, type of heat storage, and initial temperature of the device, and to reveal the change law of the device’s performance. The results show that the inlet water temperature has the most significant impact on the device’s heat storage and release performance. When the device’s heat storage or release is used for heating, changing the inlet water flow rate has a weak and limited effect on the device’s performance. However, when the device’s heat release is used to provide domestic hot water, increasing the make-up water temperature and reducing the inlet water flow rate can significantly improve the device’s effective heat release. Furthermore, based on the experimental validation of the model’s correctness, this study further simulated and studied the impact of different factors on the device’s heat storage process to optimize its structural design and provide technical references for the device’s actual operation and installation. The results show that the placement of fins has a negligible effect on the performance of the heat storage device while reducing the fin spacing and increasing the fin thickness can significantly improve the melting efficiency of the phase-change material (PCM). Additionally, the heat storage characteristics of the device are significantly better in the vertical installation mode than in the horizontal installation mode. This study provides theoretical guidance and technical references for the design and use of phase-change thermal storage devices.

Firstly, the architecture of distributed compressed air energy storage system based on regional microgrids is constructed. Then, considering the thermodynamic characteristics of the air storage device under constant volume and insulation, a cogeneration model of distributed compressed air energy storage is established. The model includes compression subsystem, air/heat storage subsystem, and expansion subsystem. Finally, the results of combined heat and power supply of distributed compressed air energy storage system are discussed by case study simulation in different air storage chamber models. The results show that constant volume insulation as the air storage device is the best choice, which improve the system efficiency by up to 25.6%.

The best solution to exploit renewable energy sources (RES) together is by using the application of microgrid (MG). This indeterminate of resources such as solar panels, wind farm, diesel generator, and battery storage system paired with load profile result in random changes within the generation and the load phases, which create it is challenging to properly manage an MG. Due to this problem energy management technique for real-time scheduling of an MG takes into consideration the uncertainty of load demand, renewable energy, and electricity price are proposed. In this paper, linear programming with two methods (optimized problem and solver based) of dual-simplex are suggested to tackle the energy management issue of the renewable microgrid. The simulation is done in each method using four cases fast wind speed with clear solar irradiance, fast wind speed with cloudy solar irradiance, slow wind speed with clear solar radiation, and slow wind speed with clear solar irradiance. The result showed that the first and second cases in the first method are higher cost than the two corresponding cases in the second method. In addition, the third and fourth cases in the first method are lower cost than the two corresponding cases in the second method.

ABSTRACTThe electrodeposition of hydrated ruthenium dioxide (hRuO2) on Ti interdigitated current collectors deposited onto silicon substrate has been investigated with the objective of preparing a high capacitance and high power micro-supercapacitor (µ-SC) device. Ti current collectors were synthesised by typical photolithography processes, and hRuO2 thin films were electrodeposited from ruthenium chloride precursors. Device specific capacitances exceeding 20 mF·cm−2 were obtained, and more than 80 % of that value is retained even at scan rate as high as 1 V∙s−1 in 0.5 M H2SO4. The mean specific power per active surface area of the device is 368 mW·cm−2. The device is stable and 90% of the initial capacity is retained after 105 cycles (1 V potential window). The characteristic response time of the hRuO2 µ-SC is 250 ms, with low ESR (0.61 Ω cm−2) and EDR (0.07 Ω cm−2) values. All these characteristics demonstrate the potential of such µ-SC devices to be part of the next generation of micro-supercapacitors.

The main reason of voltage instability in stand-alone power supply systems is the electric drive motors inrush current, which are usually higher than their nominal value. The most reasonable way to solve this problem is using capacitive energy storage. The purpose of research is shape and measurement monitoring of battery-capacitive energy storage device inrush current characteristics. Parameters comparative analysis for lithium-ion battery (LIB) part and capacitive part of the energy storage device was holding with the twochannel digital oscilloscope.Measuring testing bench included parallel connected LIB part and capacitive part of the storage device and connected to the power source. The LIB part of the storage device is made on the basis of the ATOM 10 multifunctional motor drive device of the new generation, which contains 15 V lithium-ion battery and 9.4 A·h capacity. The capacitive part of the storage device is the INSPECTOR Booster supercapacitor with an 80 F electrostatic capacitance and 15.5 V voltage. A 12 V AC/DC step-down converter was used as a power source. An electric air automobile compressor M-14001 was used as a current drain. The testing bench measuring part consisted of a two-channel digital oscilloscope and two standard measuring shunts with 15000 μOm resistance serial attached to LIB part and capacitive part of the storage device. Shape and measurement monitoring of inrush current characteristics of LIB part and capacitive part of the energy storage device was held synchronously using a two-channel digital oscilloscope with recording data to FAT32 file system USB flash drive. Obtained data was transferred to a personal computer and analyzed.The measurement results showed that 82.3 % of the energy losses compensation of the motor start is taken over by the capacitive part of the energy storage device, what makes longer LIB’s life. By adjusting the oscilloscope sweep trace index you can analyze more detailed time response shape and its duration. The values of the inrush current amplitudes were calculated in proportion to the voltage drop on the shunts and their resistances.The developed method for monitoring shape and measurement inrush current characteristics can be used in various technical applications: smart stand-alone photovoltaic system, uninterruptible power supply devices, electric drive control systems, etc.

Wind curtailment and weak inertia characteristics are two factors that shackle the permeability of wind power. An electric hydrogen production device consumes electricity to produce hydrogen under normal working conditions to solve the problem of abandoning wind. When participating in frequency regulation, it serves as a load reduction method to assist the system to rebuild a power balance and improve the wind power permeability. However, due to its own working characteristics, an electric hydrogen production device cannot undertake the high-frequency component of the frequency regulation power command; therefore, an energy storage device was selected to undertake a high-frequency power command to assist the electric hydrogen production device to complete the system frequency regulation. This paper first proposes and analyzes the architecture of a wind storage hydrogen-generating station for centralized hydrogen production with a distributed energy storage, and proposes the virtual inertia and droop characteristic mechanism of the wind storage hydrogen-generating station to simulate a synchronous unit. Secondly, an alkaline electrolysis cell suitable for large-scale engineering applications is selected as the research object and its mathematical model is established, the matching between different energy storage devices and their cooperation in power grid frequency regulation is analyzed, and a super capacitor is selected. A control strategy for the wind storage hydrogen-generating power station to participate in power grid frequency regulation with a wide time scale is then proposed. Using the first-order low-pass filter, the low-frequency component of the frequency regulation power command is realized by an electric hydrogen production device load reduction, and a high-frequency component is realized by the energy storage device. Finally, the effectiveness and rationality of the proposed control strategy are verified by establishing the simulation model of the wind storage hydrogen-generating power station with different initial wind speed states, comparing the system frequency dip values under the proposed multi-energy cooperative control strategy and a single energy device control strategy.

As the energy source a solar battery was used, with a 12 V nominal voltage and 100 W peak power. A 6 Om rheostat with 15 A consumption current was used as a load during the storage device discharge. A Morningstar ProStar-15 charging/discharging controller with a pulse-width modulation function was used to monitor and control the photovoltaic system. Quantitative charging and discharging characteristics of a battery-capacity energy storage device were obtained for the use in the development of standalone photovoltaic system.

Full textAbstract:
A solution to the problem of increasing the efficiency of traction electric drive systems, taking into account the steady increase in electricity prices, is proposed by using storage devices. Promising types of energy storage devices are considered. A comparative analysis of the main types of batteries and supercapacitors is carried out. The description, types, and main technical characteristics of batteries and supercapacitor energy storage devices are given. The choice of the best energy storage device is justified. The technical characteristics of specific models of supercapacitors are compared and the required number of individual storage devices of different models is calculated in accordance with the supply voltage of the engine and the energy consumed by them in the acceleration mode. The supercapacitor model for forming a storage battery was selected according to the following optimality criteria: minimum mass, minimum price, and minimum number of individual capacitors.

With the growth of industry manufacturers and population, power quality becomes more and more important issue, and is attracting significant attention due to the increase in the number of sensitive loads. A distribution static compensator (DSTATCOM) is a voltage source inverter (VS1)-based power electronic device, which is usually used to compensate reactive power and sustain the system voltage in distribution power system. Compared with the traditional STATCOM, multilevel STATCOMs exhibit faster dynamic response, smaller volume, lower cost, and higher ratings. A multilevel inverter connected to an energy storage device can control both active and reactive power flow, providing more flexible and versatile power transmission operation. SPWM is actually a kind of multi-pulse trigger mode and used to trigger the switches in DSTATCOM.
