Application of grid connected multilevel inverter for renewable energy integration

Abstract

This study investigates the integration concerns of next-generation renewable energy systems, in which the grid is turning more disseminate and accessible. In this case, the Permanent Magnet Synchronous Generator (PMSG) based wind energy conversion systems are expected to be more beneficial. Provision of power quality improvement such as Harmonic Reduction is the basic key to obtain higher utilization of wind energy. This functionality for future systems leads to lower energy cost, and reliable power system. To incorporate the advanced features, a five level cascaded H – bridge inverter, with reduced number of power electronic switches is progressed in this study, that is configured within the renewable source systems such as solar and wind. The study is carried out on a 10 KW PMSG based wind energy conversion system interfaced to grid. The proposed concept is elucidated through modelling, simulating and analysing in MATLAB/Simulink environment.
