Performance Analysis of a Solar-Battery-Fuel cell based Micro-grid System

Abstract

The paper presents a solar-PV, fuel cell and battery based stand-alone system and its associated control schemes to study the performance of the system under varying load and source conditions. Coordinate control scheme is used to manage the power flow among all the units of the considered system and also to maintain constant voltage across the common DC link capacitor. Droop control algorithm is incorporated with the control scheme of the load side converter (LSC) for regulating the magnitude of AC output voltage and load frequency to their rated values at different scenarios. The study model is implemented in MATLAB/simulink environment and the simulation is done extensively. Simulation responses are analyzed and results show that the study system works as per the control schemes aimed at and it gives good dynamic performance under different conditions.
