Microgrid controlling in grid connected mode using fuzzy logic controller with optimization of Der’s

Abstract

As the price of fuel is rising and GHG emission affecting environment adversely, we need to switch to renewable energy resources. To integrate all Renewable energy sources Microgrid came into existence. This paper presents a simulation and mathematical model of Microgrid in grid connected mode. This proposed system consists of two renewable sources i.e. solar energy and fuel cell energy. Modeling of solar PV system and fuel cell stack system with boost converter is explained. Main focus area of this paper is controlling of Microgrid in gird connected mode using fuzzy logic controller which enhances the power quality of system while feeding nonlinear load. Optimization of DER’S is done to utilize the resources at most keeping the cost in mind.
