PERFORMANCE ENHANCEMENT OF A PMSG-BASED WIND– SOLAR HYBRID ENERGY CONVERSION SYSTEM USING FUZZY LOGIC CONTROL

Abstract

Energy continuity is one of the important factors in the energy generation, transmission and consumption cycle. The continuous increase in energy demand causes diversity in energy resources. Alternative energy is getting more regarded because of aspects such as the fact that fossil resources are depleted and not sustainable. The hybrid energy conversion systems (HECS) are designed using two or more energy sources. The aim of this study is on the hybrid energy conversion system. A photovoltaic solar energy system and a permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) are utilized in this hybrid energy conversion system. These energy systems enable us to feed a single-phase load independent of the grid by using a seven-level the Packed U Cell (PUC7) multilevel inverter. In this study, the proposed of HECS is designed and simulated using Matlab/Simulink. The simulation results demonstrate that under changing wind speed and irradiation circumstances, the hybrid energy conversion system can produce the appropriate output voltage and output power for the load. KEYWORDS: wind energy, solar energy, hybrid energy conversion system, PUC multilevel inverter.
