Customized operation of solar-variable speed diesel generator hybrid system for remote power applications

Abstract

Now a days, the off grid hybrid energy system is increasingly popular for remote area power applications. Conventionally, the constant speed diesel generator (CSDG) is used for the most of reliable power supply. The use of CSDG causes the poor efficiency at part/low loads. The integration of renewable energy with CSDG may lead to the inefficient operation of CSDG and high fossil fuel consumption. In this paper demonstrate the solar-variable speed diesel generator (VSDG) 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 VSDG in to solar energy system gives advantage over the conventionally used CSDG. Fuel effectiveness and economic operation can be accomplished by variable speed diesel generator. Direct feeding of power from photo-voltaic 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 hybrid Energy System with variable speed Diesel generator. Simulation of the system using MATLAB/Simulink is presented.
