Reduced Switch Count Multilevel Inverter for Renewable Energy Source Application

Abstract

This concept focus on one of the challenging andimportant situation of the all the countries around the globe i.e, remote areas rural electrification. In this concept, economical andreliable hybrid renewable energy system for remote areas hasbeen implemented. The hybrid system uses a combination ofsolar and wind energy system as they are complementary andavailability is plenty in nature. It can work in standalone mode orin hybrid mode depending on the availability of the sources. Forthe efficient utilization of the solar and wind energy, a modifiedPWM inverter with minimum components is used to obtain highquality output ac power that can feed directly the loads in remoteareas. Direct drive PMSG, MPPT control, the modified PWMinverter with minimum power electronics, feeding ac and dc loads makes the system more economical, reliable for the remoteareas electrification.. The implemented hybrid energy system is used to generate and distribute power among the remote areas as the solar energy and wind energy are plenty in nature. Depending on the availability of the solar and wind energy, this system feeds the loads in standalone mode or hybrid mode. The proposed concept is implemented to 7 level, 9 level, 11 level multilevel inverterMATLAB/Simulink software is used for themodeling and simulation of the hybrid energy system
