Abstract:
It is important to improve the dynamic performance and the low-voltage ride-through (LVRT) capability of a grid-connected photovoltaic (PV) system. This paper presents synergetic control for the control of a grid-connected PV system. Modeling of a grid-connected PV system is described, and differential-algebra equations are obtained. Two control strategies are used in normal operation and during LVRT of a PV system. Practical synergetic controllers with two control strategies are synthesized. The mathematical expressions are derived for computing control variables. The design of the synergetic controllers does not require the linearization of the grid-connected PV system. A grid-connected PV system with synergetic controllers is simulated in Simulink surroundings. The control performance is studied in normal operation and during LVRT. Simulation results show that the synergetic controllers are robust and have good dynamic characteristics under different operation states.

Abstract:
This work presents a photovoltaic (PV) system, connected to a three phase grid. This work focuses on fault analysis in a grid connected photo-voltaic (PV) energy system. In this work, a three phase Multi-level Inverter connected with an AC grid fed by photovoltaic systems with advanced sine PWM control scheme is presented. The proposed modulation technique uses single reference signal and number of high frequency carrier signals to generate the PWM signal. Now a days, most of the photovoltaic (PV) power sources are connected to the AC grid. When photovoltaic power sources are connected to grid, the grid connected PV system is affected by various power quality issues like voltage sag, voltage swell, voltage disturbances, waveform distortions and three phase fault. One of the main power quality problems is three phase fault and it is appeared in the grid due to short circuit condition between two phases and ground. Fault analysis is carried out by creating a LG, LL, LLL and LLLG fault in the grid connected systems. Grid side voltage, current and power waveforms at the grid side are analysed with fault conditions. A detailed simulation has been done for the Multi-Level Inverter and the validation of system is verified through MATLAB/SIMULINK and the results are presented.

Kenya's electric power system is heavily reliant on hydropower, leaving it vulnerable during recurring droughts. Supply shortfalls are currently met through the use of expensive leased diesel generation. Therefore, plans for new generation focus on geothermal and conventional thermal sources. While these technologies offer a lower-cost alternative to leased diesel, they require large upfront capital investments in new infrastructure. I propose that grid-connected solar PV offers an alternative solution to displace expensive diesel generation, while capitalizing on Kenya's abundant solar resource and avoiding large upfront financing requirements. Coordinated operation of Kenya's extensive reservoir hydro capacity can overcome intermittency problems associated with solar generation and offer a low-cost path to grid-connected solar PV by eliminating the need for additional investment in storage. This study uses a static expansion planning model of Kenya's power system representing the years 2012 and 2017 to evaluate the feasibility of grid-connected solar PV under different price and hydrological conditions. These results reveal that high penetrations of solar PV can be integrated into the current system without increasing total system costs. By 2017 extensive planned investments in low-cost geothermal, imported hydro, and wind power will significantly reduce production from fuel oil plants and solar PV is no longer economically competitive at current prices. The 2017 analysis does not evaluate scenarios where the price of solar PV decreases, new capacity is delayed, or PV capacity eliminates the need for new transmission infrastructure required for planned generation assets. Any of these scenarios increases the competitiveness of solar PV in the 2017 system. The methodology developed in this study could be used for system level evaluation of solar and other intermittent renewables in other hydro-dominated electric power systems in Africa.

Abstract:
The growth of the photovoltaic market indicates that in the near future PV electricity generation may rise to a significant power source. As the proportion of electric power generated from PV systems becomes significant, the effect of these sources on transmission and distribution networks must be considered. This research work has investigated suitable representations of the PV resource and the output power of dispersed PV systems to study the effects of large-scale deployment of PV systems on the grid operation. The representation of solar radiation is very important since this dictates the output power of PV systems. In this work, the simple and reliable Markov Transition Matrix (MTM) method was selected to generate synthetic horizontal solar radiation data. A single MTM was developed to generate half-hour horizontal solar radiation data for different locations in the UK. Large-scale inclusion of PV systems in the UK electricity supply is expected to take the form of a large number of small, geographically dispersed building integrated PV systems. The study also developed a detailed PV cluster model to represent these dispersed PV systems. The variation of PV output power may impact the demand and generation balance on the network requiring additional reserve generation to ensure the system security. In this work, the variation of PV output power and the impact on the reserve requirement was analysed for different penetration levels. This is also the first study to analyse the correlation of solar radiation for different locations in the UK in regard to the impact on reserve requirements. Using data from three locations and according to the National Grid Company (NGC) requirements, it was found that PV capacities of 3750 MW could be added to the present network without additional reserve requirements. The additional reserve required is not on the basis of "MW of reserve per MW of PV capacity". Rather it is based on the aggregation of load demand and of PV output from all regions. The reduction in the reserve requirement by forecasting the weather profile of the day was also illustrated. In this case, a PV capacity of 22,500 MW, which can generate a little over 5% of the UK electricity demand, can be added with minimal increase in system cost. Therefore, the variation of PV output power is unlikely to be a threat to the system security.

Cette thèse a pour but l'analyse d'un système photovoltaïque connecté au réseau électrique en prenant en compte le contrôle, l'étude de la stabilité et la fiabilité. Un onduleur de type 2-Niveau a été comparé avec un onduleur multi-niveaux appelé Neutral Point Clamped. Les avantages et désavantage de chaque topologie ont été analysé en considérant l'efficacité énergétique, l'optimisation de l'injection de l'énergie sur le réseau électrique et la fiabilité du système. Pour le contrôle du courant de sortie de l'onduleur, ont été proposées deux solutions : un contrôle basé sur la théorie de la platitude et un contrôle par passivité. Ces deux différents contrôles sont comparés par rapport à la robustesse, la complexité et le nombre de capteurs utilisés. Il a été montré que les deux contrôles sont capables de gérer la problématique de la résonance du filtre LCL. Pour augmenter l'efficacité de l'algorithme MPPT dans une configuration Distributed-MPPT avec la connexion en série des deux sorties des convertisseurs boost, une nouvelle technique a été proposé pour l'équilibrage des tension d'entrée d'un onduleur NPC. En utilisant un outil appelé TPtool, un étude de la stabilité large signal par "Higher-Order-Singular-Value-Decomposition" a été présenté et comparé avec une méthode basée sur les modèles Takagi-Sugeno pour des systèmes non-linéaires. Finalement, l'onduleur 2-Niveaux est comparé avec deux multi-niveaux différents (NPP et NPC) en termes de disponibilité, en prenant en compte les niveaux de redondance des convertisseurs. Pour analyser la disponibilité, a été considérée la théorie des chaines de Markov et pour l'implémentation, le logiciel GRIF a été utilisé
The aim of this PhD thesis is to analyze a PV-grid connected system in terms of control, stability and reliability. A comparison between a classical 2-Level inverter and a multilevel NPC is presented. The advantages and weakness of both the converters are analyzed with respect to the power efficiency, optimization of the energy injection to the grid and reliability of the system. In order to control the inverter output current, two different solutions are proposed: flatness-based control and passivity-based control. These controls are compared in terms of robustness, complexity and number of sensors used. It is shown that both the controls may manage the resonance problems due to a LCL filter. For increasing the efficiency of the MPPT in a configuration Distributed-MPPT with connections in series of the boost converters outputs, a novel technique for the dc voltages balancing of a NPC inverter is proposed. A large stability analysis using "Higher-Order-Singular-Value-Decomposition" is presented and compared with Takagi-Sugeno approach for nonlinear systems. Finally, 2-Level inverter is compared with two multilevel inverters (NPC and NPP) in terms of availability, considering the redundancy levels of the converters. To analyze the systems availability, the Markov chains theory is considered and it is implemented on GRIF

Abstract:
This research applies a recently developed dynamic state-estimation based protection scheme, the settingless protection, to the photovoltaic (PV) industry for the first time. At this time, the proposed protection algorithm has been implemented on traditional protection zones for individual power system devices, but this research extends this protection to a microgrid, specifically, a system of PV network composed of several PV modules. Several illustrative examples on various anomalies such as high impedance faults and shorted-out PV modules have been provided to demonstrate the effectiveness of this protection scheme. The detection of these anomalies has been demonstrated in the presence of changing atmospheric conditions, and with the operation of maximum power point tracking (MPPT) equipped dc-dc converters. This protection scheme requires an accurate model of the PV module, therefore, a two-diode PV model has been developed using quadratic integration modeling. In this PV model development, a scaling factor is applied to the Taylor series expansion of the exponential terms of the model of the PV module. Then the higher order terms of the Taylor series expansion are reduced to at most second order terms using the quadratization technique. Furthermore, a novel approach for extracting the PV parameters, namely, the ideality constants, leakage currents, PV module internal current, shunt and series resistances, has been presented. A comparison was performed between numerically generated data using the determined PV module parameters and data measurements from a physical PV module. It was shown that the maximum error from this comparison was below 0.12A, and less than 0.05A around the maximum power point region of the PV modules used for this research. The residual data from the PV array protection scheme has been used to develop a method for identifying the location of faulted PV modules. Also, condition-based monitoring of the PV array system has also been presented with examples. From the PV array system monitoring, the shading and underperformance of a PV module have been identified. From the contributions of this research, an accurate module of the PV array has been developed in a form that can be integrated with other power system devices. This accurate module can be used for state estimation of the PV array, load flow analysis, short circuit analysis, and other power system analytical studies. Also, by determining the location of the faulted PV module, the time to identify this faulted PV module in a large PV installation is drastically reduced. Lastly, by identifying shading conditions and underperforming PV modules, the PV system operator can quickly bring the underperforming module or modules to optimal performance, thereby, maximizing the power yield of the PV array, and maximizing the revenue of the PV system owner.

Dissertation (DTech(Electrical Engineering))--Cape Peninsula University of Technology, 2012
The confluence of the limited resources of fossil fuels (e.g. coal, oil and natural gas), environmental degradations leading to climate change, security of supplies and fossil fuels high costs have demanded a tremendous efforts on humanity to seek for a sustainable and unlimited natural energy sources. Amongst these renewable energy sources stands out solar energy because of its ubiquitousness. Solar energy is converted to DC electricity by the photovoltaic effect. Photovoltaic (PV) power systems installed in commercial and industrial buildings are a good example of distributed power generation. Here the energy consumption and production match and thus electricity taken from the grid during daytime peak hours can be reduced. This is beneficial as the transmission losses in the grid are avoided and also transmission need is reduced. The cost effectiveness of a solar energy system has hindered its wide adoption and deployment in terms of the initial capital cost even though it has a zero energy cost and very minimal operating and maintenance costs. Different governments have instituted many financial incentives for fast adoption of PV systems for both residential and commercial applications. However, all these incentives are not sustainable in the longer term forecast. For PV system to attain grid parity requires more than unsustainable approach of many governments providing time limited subsidies. The technical solution to the problem is to reduce the overall system cost through technical innovations. One such method is the adoption of transformerless inverter technology as the grid interface system. Transformerless inverter topology provides galvanic isolation through innovative inverter topology and switching strategies that eliminates problems created by not employing the service of transformer.

Abstract:
Considering the long term target set by the Swedish government of having an energy system basedexclusively on renewable sources, the potential for different renewable sources need to beinvestigated. When analyzing the sources used for electricity production in Sweden today, solarPV represents a very small share. This relatively small share also mainly consists of grid-connecteddistributed PV systems, and to analyze the possibilities of making solar energy a larger share inthe electricity production in Sweden this study will focus on grid-connected centralized PV farms.The main purpose of the study is to identify the potential for grid-connected centralized PVsystems for large scale production in Sweden. This will include an identification of the mostimportant key factors influencing the profitability, an investment calculation to be aware of theprofitability, a prediction of the future development of the PV industry in Sweden and lastly themain challenges that the PV industry is facing.To conduct this study a collaboration with Vattenfall Vind AB has been made, where a case studybased on three specific locations has been implemented when analyzing both the profitability andthe key factors. These three cases are based on places where Vattenfall has existing wind farms orhas assigned for upcoming ones. These areas could be seen as a potential benefit since the companyalready has started to inspect the land area, and that wind and PV farms might be able to sharenecessities such as infrastructure.The results of the study mainly indicate that the PV industry most likely will continue develop andgrow, but the profitability of investing in grid-connected centralized PV farms does not lookpromising today or in the next coming years. This mainly due to low prices for electricity anduncertainties in the future development of the financial support policy. The location is also veryimportant for this type of installation. There are places in southern Sweden with enough insolation,but these areas can be seen as limited. To make solar energy a larger share of the electricityproduction in Sweden in a profitable way today, more investments should be made in gridconnecteddistributed PV systems rather than grid-connected centralized PV farms. PV farms forlarge scale production might though be more profitable in the future when the prices for modulesand inverters will decrease further and when the spot price increases.

Abstract:
This thesis focuses on the single-phase voltage-source inverter for use in photovoltaic (PV) electricity generating systems in both stand-alone and grid-tied applications. In many cases, developments in single-phase PV systems have followed developments in three-phase systems. Time-variant systems are more difficult to control than time-invariant systems. Nevertheless, by using suitable transformation techniques, time-variant systems can often be modelled as time-invariant systems. After the transformation, the control signals that are usually time-variant (often varying sinusoidally in time) become time-invariant at the fundamental frequency, and are hence much easier to deal with. With this approach, synchronous rotating frame control techniques have been previously proposed for high performance three-phase inverter applications. The transformation theory cannot be applied directly in single-phase systems without modification, and the d-q components would not be time-invariant in situations where harmonics, resonances or unbalance is present. Single-phase inverter controller designs based on the use of a synchronous rotating reference frame have been proposed, but such designs do not always perform as well as expected. This thesis aims to improve single-phase voltage-source inverters. The main objective is to address, in terms of cost, efficiency, power management and power quality, the problems found with single-phase designs based on a synchronous rotating frame single-phase inverter controller. Consequently, this thesis focuses on a novel controller approach in order to obtain a more reliable and flexible single-phase inverter. As the first step, this thesis investigates the single-phase inverter switching gate-drive algorithms and develops a form of space-vector pulse-width-modulation (SVPWM) in order to reduce total harmonic distortion. The results of the new SVPWM algorithm demonstrate its superior performance when compared with sinusoidal pulse-width-modulation (SPWM) which is often used with single-phase inverters. The second step, which is further reviewed and presented in this thesis, is the modelling of the single-phase inverter control based on the synchronous rotating frame. A mathematical analysis is conducted to determine the mechanism of the coupling that exists between the voltage phase and amplitude terms, and a new transformation strategy is proposed based on using the voltage phase as a reference at the Park transformation stages, and the current phase as a reference for the current at the transformation stages. The line-frequency components of the feedback signals are transformed to time-invariant components, thus eliminating the ripple and reducing the computational burden associated with the controller stage. Consequently, the inverter feedback controller stage is designed so that the coupling terms are decoupled within the controller itself. The effectiveness of the techniques proposed in this thesis are demonstrated by simulation using the MATLAB/SIMULINK environment. The proposed technique was also investigated through a practical implementation of the control system using a Digital Signal Processor (DSP) and a single-phase inverter. This practical system was tested up to 1 kW only (limited by the available inverter hardware). Nevertheless, the correlation between the simulation and the practical results is high and this gives confidence that the developed mechanism will allow the 2.5kW goal to be achieved. Practical test cases illustrate the effectiveness of the models. In addition, the comparisons between experimental and simulation results permit the system's behaviour and performance to be accurately evaluated. With the development of the new controller, small-scale single-phase renewable energy systems will become more useful in the field of power quality management through their ability to separately control the phase and amplitude of the output voltage. Consequently, incorporation of this type of generator within the national electrical distribution network, as distributed generators (DG) at low-voltage level, can assist with power quality management at the consumer side of the grid. In addition, such a generator can also operate in stand-alone mode if the grid becomes unavailable. The third step in this thesis investigates small-scale single-phase renewable energy systems operating as decentralized distributed generators within a local network. This operation is achieved by controlling the inverter side using the quantities measured at the common coupling point between the grid and the inverter, without requiring other extensive communications. Thus, the small-scale single-phase renewable energy distributed generator systems will contain only a local controller at each installation.

Abstract:
Backup diesel generator (DG) systems continue to be a heavily polluting and costly solution for institutions with unreliable grid connections. These systems slow economic growth and accelerate climate change. Photovoltaic (PV), energy storage (ES), grid connected, DG – Hybrid Energy Systems (HESs) or, PV-HESs, can alleviate overwhelming costs and harmful emissions incurred from traditional back-up DG systems and improve the reliability of power supply. However, from project conception to end of lifetime, PV-HESs face significant barriers of uncertainty and variable operating conditions. The fit-and-forget solution previously applied to backup DG systems should not be adopted for PV-HESs. To maximize cost and emission reductions, PV-HESs must be adapted to their boundary conditions for example, irradiance, temperature, and demand. These conditions can be defined and monitored using measurement equipment. From this, an opportunity for performance optimization can be established. The method demonstrated in this study is a techno-economic and environmental approach to improving the performance of PV-HESs. The method has been applied to a case study of an existing PV-HES in Kenya. A combination of both analytical and numerical analyses has been conducted. The analytical analysis has been carried out in Microsoft Excel with the intent of being easily repeatable and practical in a business environment. Simulation analysis has been conducted in improved Hybrid Optimization by Genetic Algorithms (iHOGA), which is a commercially available software for simulating HESs. Using six months of measurement data, the method presented identifies performance inefficiencies and explores corrective interventions. The proposed interventions are evaluated, by simulation analyses, using a set of techno-economic and environment key performance indicators, namely: Net Present Cost (NPC), generator runtime, fuel consumption, total system emissions, and renewable fraction. Five corrective interventions are proposed, and predictions indicate that if these are implemented fuel consumption can be reduced by 70 % and battery lifetime can be extended by 28 %, net present cost can be reduced by 30 % and emissions fall by 42 %. This method has only been applied to a single PV-HES; however, the impact this method could have on sub-Saharan Africa as well as similar regions with unreliable grid connections is found to be significant. In the future, in sub-Saharan Africa alone, over $500 million dollars (USD) and 1.7 billion kgCO2 emissions could be saved annually if only 25 % of the fuel savings identified in this study were realized. The method proposed here could be improved with additional measurement data and refined simulation models. Furthermore, this method could potentially be fully automated, which could allow it to be implemented more frequently and at lower cost.

Abstract:
The task of this master thesis is to evaluate the potential and economic feasibility of a solar photovoltaic project at the Castle Château de la Chaize, situated near Lyon in France. The domain of the Château de la Chaize aims to be more ecologically responsible, by producing organic wine, using geothermal energy and producing its own electricity, using solar energy. The solar system would hence be used to produce the electricity that the castle and the vineyard would use. Since the whole domain is changing in order to be more sustainable, the energy consumption is still unclear. Three consumption scenarios are thus studied to model: the current situation (108 MWh), the change in energy needs due to the renewal of the wine making process (568 MWh), and finally the additional energy demand due to the construction of a spa on the domain lands (1056 MWh). The project site is also situated in the domain, near the Castle. The meteorological data and the shading scene are gathered from databases and site visits. Since the site is oriented towards the North-West and the South and East sides are blocked by a forest, significant shading losses are expected. In order to maximize the potential of the PV system, the use of Li-Ion batteries, to increases the self-generated part of the consumed electricity, is also considered. Simulations for the system production and the matching of the consumption and production is lead using the PVsyst software. Standard modules and inverters are used to run the simulation. The different configurations (energy consumption, size of the PV system, battery,...) are compared using the self-generation rate (part of the energy that is consumed that comes from the PV system) and financial criteria such as the Internal return rate or the profit at year 20. The results show that using a solar system to provide electricity for the current scenario would not be financially viable. For the renovation scenario, the best system design is the southward oriented fixed tilted plane at 350 kWp. It generates a profit of 71 k€ and has a self-generation ratio of 31.5 %. For the spa scenario, the 350 kWp south-oriented system is also the most interesting, with a self-generation rate of 29.8 % and IRR of 9.33 %. The financial analysis of the systems with batteries shows that the investment costs of the storage system are too high, and its lifetime is too short to be profitable. It would be interesting to see the evolution of the energy storage market, that is expected to develop, to see the economic interest of installing storage systems.
Uppgiften för detta examensarbete är att utvärdera potentialen och den ekonomiska genomförbarheten för ett solcellsfotovoltaikprojekt vid slottet Château de la Chaize, beläget nära Lyon i Frankrike. Domänen för Château de la Chaize syftar till att vara mer ekologiskt ansvarig, genom att producera ekologiskt vin, använda geotermisk energi och producera sin egen elektricitet med solenergi. Därför skulle solsystemet användas för att producera den elektricitet som slottet och vingården skulle använda. Eftersom hela området utvecklas för att bli mer hållbar är energiförbrukningen fortfarande oklar. Tre konsumtionsscenarier studeras sålunda för att modellera: den aktuella situationen (108 MWh), förändringen i energibehov på grund av förnyelsen av vinframställningsprocessen (568 MWh) och slutligen den extra energibehovet på grund av ett nytt spa på domänen landar (1056 MWh). Projektplatsen ligger också i domänen, nära slottet. Meteorologiska data och skuggningsscenen samlas in från databaser och webbplatsbesök. Eftersom platsen är inriktad mot nordväst, och södra och östra sidan blockeras av en skog, förväntas betydande skuggningsförluster. För att maximera PV-systemets potential övervägs också användning av Li-Ion-batterier för att öka den självgenererade delen av den förbrukade elen. Simuleringar för systemproduktion och matchning av konsumtion och produktion är bly med hjälp av PVsyst-programvaran. Standardmoduler och inverterare används för att köra simuleringen. De olika konfigurationerna (energiförbrukning, storleken på PV-systemet, batteriet, ...) jämförs med hjälp av självproduktionshastigheten (en del av energin som förbrukas som kommer från PV-systemet) och ekonomiska kriterier som intern avkastning eller vinsten vid år 20. Resultaten visar att användning av ett solsystem för att tillhandahålla el till det aktuella scenariot inte skulle vara ekonomiskt hållbart. För renoveringsscenariot är den bästa systemdesignen det söderutorienterade fasta lutningsplanet med 350 kWp. Det ger en vinst på 71 k € och har en egenproduktionsgrad på 31,5 %. För spa-scenariot är det sydorienterade systemet med 350 kWp också det mest intressanta, med en egenproduktionshastighet på 29,8 % och IRR på 9,33 %. Den ekonomiska analysen av systemen med batterier visar att investeringskostnaderna för lagringssystemet är för höga och att dess livslängd är för kort för att vara lönsam. Det skulle vara intressant att se utvecklingen av energilagringsmarknaden, som förväntas utvecklas, att se det ekonomiska intresset av att installera lagringssystem.

Abstract:
Fossil fuels and non-renewable resources are being replaced with, as modern day society has coined the term, green energy. This movement towards green energy creates a demand for renewable energy resources, such as solar photovoltaic (PV) systems. This study used Geographic Information Systems (GIS) in conjunction with Remote Sensing (RS) practices and two weighting systems the Analytical Hierarchy Process (AHP) and Rank-Order methods for PV site selection. Six multi-criteria models were developed using spatial factors and constraining images to locate potential photovoltaic power plant sites for three settings of fixed axis PV arrays. This analysis was performed at a macro regional scale and further analysis is encouraged for micro site selection.
