In various studies on photovoltaic, major progresses have been observed, both concerning the cells and also in the field of their use. In order to take advantage of the energy it has been paramount to focus on parallel High Voltage bus. This High Voltage generation requires dedicated converters. In fact, using classical converters implicates important losses in the MOSFET used for switching. In a prior study we could ascertain important losses on transistors when submitted to high voltages as we assumed. It was shown then that only the transistors supporting a voltage less than 100V can be used for our application. A systematic investigation led to the Magnetically Coupled Boost converters. Thanks to the recycling of parasitic losses, our tests show an efficiency superior than 90%. Among the different power extraction strategies, the incremental conductance MPPT was used because of its top of the arts performances and convenience. Every DC/DC implemented panel converter supplies the HVDC bus which, itself, is connected to the SMA inverter

Etude comparée des méthodes de mesure des coefficients électro-optique : application à LiNbO3 by Michel Aillerie( Book )

2 editions published in 1991 in French and held by 2 WorldCat member libraries worldwide

The thesis presents a study and the development of optical arrangements and measurement techniques for the determination of electro-optic coefficients (E/O). This work belong to the optoelectronics area in which electro-optic applications are numerous and promising (in fields such as optical transmission, parallel processors, ...). The crystal under study is the lithium niobate, very often used for bulk modulators and in integrated optics. Nevertheless, its ferroelectric, thermo-optic and electro-optic behaviour is very complex and, as yet, not perfectly know. To determine the electro-optic coefficients, we have considered various kinds of methods, based on optical arrangements using either one beam, such as the compensator setting configurations, or two beams, such as the interferometric methods. To extract the E/O coefficient, we can perform measurements of the beam intensities, the half-wave voltage or the shift of the minimum transmitted intensity value. These methods are used with static (DC) and/or dynamic (AC) applied voltages. The report describes for each method the principle, the experimental results obtained for the rc coefficient of LiNbO3, and then a critical analysis of the results with a view to the accuracy. After a brief presentation of the thermo-optic (T/O) effect, comparisons and discussion of the results follow. The consequences of the TIO effect on the validity of the measurement are also considered. In the last pan of this report, we describe the one beam F,IO null-setting method developped in the laboratory. In addition, we present the control and âc\ruiSition systems which enabled an automaûc executing of the experiment

Defect Modulation Doping for Transparent Conducting Oxide Materials by Getnet Kacha Deyu( )

1 edition published in 2019 in English and held by 2 WorldCat member libraries worldwide

The doping of semiconductor materials is a fundamental part of modern technology.Transparent conducting oxides (TCOs) are a group of semiconductors, which holds the features of being transparent and electrically conductive. The high electrical conductivity is usually obtained by typical doping with heterovalent substitutional impurities like in Sn-doped In2O3 (ITO), fluorine-doped SnO2 (FTO) and Al-doped ZnO (AZO). However, these classical approaches have in many cases reached their limits both in regard to achievable charge carrier density, as well as mobility. Modulation doping, a mechanism that exploits the energy band alignment at an interface between two materials to induce free charge carriers in one of them, has been shown to avoid the mobility limitation. However, the carrier density limit cannot be lifted by this approach, as the alignment of doping limits by intrinsic defects. The goal of this work was to implement the novel doping strategy for TCO materials. The strategy relies on using of defective wide band gap materials to dope the surface of the TCO layers, which results Fermi level pinning at the dopant phase and Fermi level positions outside the doping limit in the TCOs. The approach is tested by using undoped In2O3, Sn-doped In2O3 and SnO2 as TCO host phase and Al2O3 and SiO2-x as wide band gap dopant phase
Gestion et conversion électrique dans une architecture distribuée d'énergies renouvelables by Thế Vịnh Nguyễn( )

1 edition published in 2014 in French and held by 1 WorldCat member library worldwide

Managing the distribution of electrical energy from renewable sources such as solar and wind energy is a technological barrier to improve performance and stability of the whole process of transfer of energy sources. Thus, research on power lines used as communication media are very promising for the facility management of small and middle powers with many generators, not necessarily initially designed in a process reliability. In addition, this new option allows management to improve performance and stability in the overall process of energy transfer. This study is particularly directed to a distributed parallel management for photovoltaic and / or multi-generators including other technologies such as wind, for example connected to a DC network also serves as a communication such as PLC system architecture. The PLC, using the modulation technique, allows the transfer of information such as temperature, the instantaneous power, the self-test etc. ... needed to optimize the energy production. The aim of this work is the study of a CPL solution designed to work on HVDC bus connecting renewable energy production systems. Circuits developed for the CPL will be considered as interfaces between the DC-DC converter and smart HVDC bus. They will be based on a hardware part consists of a transceiver interface incorporating a modulation-demodulation on the HVDC bus and a signal processor which processes the information exchanged between the various input sensors and monitoring
Capacitance Evolution of Photovoltaic Solar Modules Under the Influence of Electrical Stress( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: The main purpose of this work was to study the effect of electric currents reverse stress on the capacitance and in general the performance of photovoltaic modules. Different levels of reverse stress current are injected into the solar cell structure and the C-V characteristic are measured in the dark and illuminated conditions, at room temperature for several common periods of time. A digital double exponential model was used to analyze the experimental measurements. The dramatic changes in capacitance characteristics are caused from the effect of a reverse current introduced for different stress levels, simulated the effect of accumulated extreme reverse currents that can occur in the solar cells and modules for different reasons. The paper contributes to research on the adverse effects of reverse currents on the capacitance and normal functioning of cells and solar modules
Technical and Economic Sizing of the Energy Storage in an Autonomous Hybrid Power Generator for Rural Electrification in Sub-equatorial Area of Africa( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: This paper analyzes and evaluates the possible technical and economical optimization of electricity production by autonomous hybrid power generator from renewable sources integrating an electrochemical storage system. A progressive combination of wind-turbines to photovoltaic modules is carried out in order to minimize the size of the electrochemical storage system over the cost of the resulting autonomous generator. An autonomous system with solar PV is dimensioned with respect to the needs in electricity of a given electrical installation. Beyond the original methodology presented in this paper, the case of the Maroua-Kongola High School site is investigated as applicative example. Considering the "weight" of storage in the overall financial costs of such an autonomous system, the generator is hybridized by attaching wind-turbines to it, adding a possibility of energy production during night and, consequently making the system technically more reliable with a less need of storage capacity and finally, a global production system economically cheaper. By the so called "down approach" dimensioning method, the optimum combination (f, (1-f)) of photovoltaic and wind power contributions in the hybrid system PV-wind power generator is thus determined by adjusting the storage capacity to the source capacities and the operating requirements of the investigated site

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: This paper proposes a new microinverter topology dedicated to photovoltaic off-grid systems or connected to the grid. This Microinverter is based on simple boost with high gain in the aim of a reduction of the total number of active components allowing, thus a high efficiency conversion. In a first part of this contribution, we describe the general topology of this micro-inverter and present the simulation tests developed in order to validate its functioning. Finally, the last part is dedicated for discussion of the simulation results, the efficiency of this topology and the feasability of its used in a photovoltaic generation system connected to the grid
Photovoltaic panels characterization and experimental testing( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: In the current work, we have analyzed the modeling in MATLAB Script similator and the electrical characterization of photovoltaic (PV) panels currently commercialized. By taking account the electrical characteristics provided by the supplier. Using the MATLAB Script simulator we deduce the optimal electrical quantities of the PV panel (current, voltage and power) according to the variable climatic conditions (irradiation and temperature). In our case, we have chosen the panel ZT180S, we have deduced from the analysis of the results of its electrical characterization that its optimal electrical quantities are 5% lower than those deduced by the electrical characteristics supplied by the manufacturer. Finaly, the model has been validated with experemental data of a commercial PV module, ZYTECH 180S

Technical and economic analysis of hybrid solar/wind energy source for the site of Tlemcen-Algeria( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: The use of renewable resources is experiencing a great boom in industrialized countries and even in some underdeveloped countries. Algeria has provided a great effort for rural electrification and Saharan. Indeed, the rate of national electrification in 2001 was equal to 96%. Despite this high rate, there are still scattered households with electrification, by extension of the conventional network, is very expensive. The hybrid power generation system (wind - PV), fully autonomous, is a solution for this problem. We present in this work, first, a method to determine the size and optimization of a photovoltaic-wind hybrid system for medium power. Secondly, determine the optimum techno economic configuration two different methods: the annual monthly average and that of the worst month. For that, load is fixed a 2kWh/d, the worst month of the method gives a higher cost of the system compared to that of the average monthly values per year. The results also show that the use of a wind system as a backup system with a photovoltaic system generates an increase in the price of the hybrid system to the site of Tlemcen
Capacitance evolution of PV solar modules under thermal stress( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract: The main purpose of this work is the study of the performance of PV modules under influence of thermal stress. Different levels of temperature were applied into the solar cell structure and the C-V characteristic was measured, in passive and active conditions, for using 10 minutes periods of time for each dose of stress. The changes in characteristics, caused the temperature parameter introduced for different stress levels, were monitored. Experimental evidence confirmed that different levels of temperatures are major degrading factor affecting the performance, efficiency, and power of solar cells and modules. The paper contributes to research on the adverse effects of temperature on the capacitance and normal functioning of cells and solar modules
Optimization of Power Line Communication System Using a Resonant HVDC Bus in a Distributed Renewable Energy Generator( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: The development of smart grid architecture for renewable energy production system is intensively studied for the possibilities that this architecture offers to optimize the global production and to increase the efficiency of the generator by monitoring individually the various sources subjected to diverse working conditions. To assume monitoring and intelligence in the grid and to communicate between remote stations and a central master one, a communication system needs to be associated to the power grid of the global production equipment. In this contribution we analyzepower line communication solutions in terms of quality of transmitted signal, efficiency and electromagnetic compatibility. We analyze the working modesof communication interfaces based on power line communication using the amplitude-shift-keying (ASK) modulation and integrating a light protocol of Modbus type. We point out that basic solutions offer poor quality of signal and generate a lot of harmonics of the fundamental carrier inducing important electromagnetic perturbations. An original solutionis thus developed, based on a narrow spectrum carrier on resonant HVDC bus working at a low frequency allowing to minimize the generation of harmonics and thus to increase the quality of the transmitted information. A PLC interfaceis then implemented in a hardware circuit and test pointing out the advantages of the PLC communication based on a resonant HVDC bus with sinusoidal carrier for renewable energy generator
