In recent year's renewable energy sources have become a useful alternative for the power generation. The power of photovoltaic is nonlinear function of its voltage and current. It is necessary to maintain the operation point of photovoltaic in order to get the maximum power point (MPP) in various solar intensity. Fuzzy logic controller has advantage in handling non-linear system. Maximum power ...

with the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. the novel concept of photovoltaic powered ...

this paper presents a cooperative control which is applied to the secondary control of a microgrid controlled via a multi-agent scheme. balancing power that leads to voltage and frequency stability in a microgrid is essential. the voltage and frequency regulations are limiting within the specified limits and conveying them to their nominal values. limiting and conveying the voltage and frequenc...

Increasing of word demand load caused a new Distributed Generation (DG) to enter to powersystem. One of the most renewable energy is the Photovoltaic System. It is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.In this paper an optimal PID controller for Photovoltaic System systems has been developed. Theoptimization techni...

daily sunshine duration is one of the factors influencing the size of solar panels in a photovoltaic system. when the system is designed and the number of system components is calculated, the average of sunshine hours is usually used. however, sunshine hours are less than average and we are faced to shortage and surplus of electricity in the winter and summer, respectively. in this paper due to...

Pumping water is one of the most popular technologies solar energy for irrigation or drinking supply. Its performance depends on characteristics site (sunlight, ambient temperature, geographical obstacles), modules, as well as, other equipment (converter and pump). The optimal sizing a photovoltaic pumping system makes it possible to guarantee satisfaction demand throughout period model electri...

The performance of a photovoltaic solar water pumping system (PVSWPS) promising in heating has been studied experimentally. design array configuration can affect the (PVSWPS), pump characteristic, flow rate and overall efficiency. aim present work is to determine an optimum that supply with optimal amount energy. Three different configurations have tested (4S, 2S ×2P 4P). experiments carried ou...

Abstract With proper management, the modernization of irrigation systems makes it possible to improve efficiency application and use water at cost an increase in pumping needs and, therefore, increment energy consumed. The recent drastic price for put viability many farms risk. In this context, using photovoltaic solar power stations has become increasingly attractive alternative a cheap reliab...
