Modelling and simulation of distributed generation system using HOMER software

A microgrid is an integrated form of Distributed Energy Resources (DERs) which are connected together to serve electrical power to the selected consumers or can exchange power with the existing utility grid under stand alone or grid connected mode. Distributed generators can provide high reliability by providing on-site generation. As a result of this many hybrid systems came in existence like PV cells, fuel cells, micro turbines, wind, diesel and small hydro systems. The distributed generation system having Photo Voltaic (PV), wind turbine and diesel generator is simulated and analyzed. This paper gives simulation results of PV-Wind-Diesel hybrid system. HOMER (Hybrid Optimization Models for Energy Resources) power optimization software by NREL (National Renewable Energy Laboratory) is used to simulate and analyze the PV-Wind-Diesel hybrid system.
