Design and Simulation of Renewable Energy Based Photovoltaic Power Plant using Matlab Simulink

Only a small fraction of the available solar energy is used in practice..To harvest the solar energy, the most common way is to use photovoltaic panels which will receive photon energy from sun and convert to electrical energy. The efficiency of PV module is very low and power output depends on solar irradiation level and ambient temperature, so maximization of power output with greater efficiency is of special interest. In this project, Advance DC- DC Converter use for a photovoltaic (PV) power-generation system is proposed. The topology used raises the efficiency for the dc/dc converter of the PV power conditioning system (PVPCS), and it minimizes switching losses by adopting a resonant soft-switching method. The proposed controller scheme utilizes PWM techniques to regulate the output power of dc-d converter at its maximum possible value. This converter is able to turn on both the active power switches at zero voltage to reduce their switching losses and evidently raise the conversion efficiency. Output of DC DC converter is given to in novel H-bridge inverter which maintain sinusoidal output with less harmonic distortion. The resulting system has high-efficiency, lower-cost. The circuit will be simulated using MATLAB.
