A Novel Power Management Strategy for Solar-Variable Speed Diesel Generator Hybrid System

Off grid hybrid energy system is increasingly popular in remote area applications. In this paper demonstrate the Solar-Variable speed diesel generator hybrid energy power system without energy storage element. This setup maintains a strategic distance from the high cost of battery installation and the related complex control. Incorporation of the variable speed diesel generator in to hybrid energy system gives advantages over the conventionally used constant speed diesel generators. Fuel effectiveness and economic operation can be accomplished by variable speed diesel generator. Direct feeding of power from PV and VSDG without cycling through the battery is further increase the efficiency of the system. This paper covered the theoretical analysis, modeling and simulation of Highbrid Energy System with Variable speed Diesel generator. Simulation of the system using MATLAB/Simulink is presented.
