Fuzzy Logic based MPPT Control of Hybrid Power Generation System

This paper describes the modeling of integrated hybrid renewable energy system. The wind and solar are used as input sources for the hybrid system. The proposed system involves the design of photovoltaic (PV) and wind energy conversion system (WECS).The system is designed for constant wind speed and varying solar irradiation and insolation. Maximum power point tracking (MPPT) algorithm is used to extract the maximum power from PV array. The integration of two input sources is done by current-sourceinterface multiple-input (MI) cuk converter. Fuzzy logic controller is used to control the duty cycle of one of the converter switch thereby extracting the maximum power from solar array. The system consists of photovoltaic (PV) array, wind energy conversion system (WECS), multiple input current- source-interface cuk converter, voltage source inverter (VSI), LC filter and three phase load. The entire proposed system has been modeled and simulated using MATLAB/simulink software. The simulation results show that the proposed system generates a power of 30KW at low cost
