Design and Simulation Based Stand-alone Solar Micro Grid System for Island Areas

Nowadays photovoltaic (PV) based power generation is developing progressively fast as a sustainable power source. This paper presents the designing of a smart distributed of stand-alone solar Micro-grid system, which is suitable for islanding areas as conventional power system is very tough and costly to supply electricity in island areas. The proposed method can offer improvement of system reliability and efficiency for the stand-alone solar micro-grid which is composed of circulated load, generation and energy storage device combined together in the region to one another. All these models of Micro-grid system are simulated by using MATLAB/Simulink. The stand-alone solar micro-grid has been analyzed with single phase full bridge DC to AC inverter, DC to DC Boost converters, battery discharge condition, and backup condition. Finally, different cases of this method are analyzed by simulated in this paper and the results have verified the validity of models successfully.
