Perturb And Observation Based Mppt Control Of Solar Pv System Using Boost Converter

Abstract

The model is used for observing and studying the performance of photovoltaic system in nonideal conditions that causes multiple maximum power points (MPPs) on the powervoltage (PV) characteristics curve. a typical solar generation system consists of a solar array and a DC/DC converter. Making the output of the solar array maximum does not certainly result in the maximum DC/DC converter output. Therefore, it is suggested that the PV array and the DC/DC converter should be considered as one system to maximize the overall system output. Since the efficiency of PV-panel is low, advanced power electronics converter are employed to improve the overall system efficiency. The solar panel is modeled and analyzed in MATLAB/SIMULINK. To get the maximum efficiency and maximum power the entire system must be linked with MPPT technique. Perturb and Distribution algorithm is used to obtain MPPT. Boost DC-DC converter is used for matching load impedance with PV arrays.
