The aim of this work is to improve the power quality for Distributed Generation (DG) with power storage system. A microgrid consists of several Decentralised Generations connected near the load. In this paper wind, PV array is used as primary generations and Proton Exchange Membrane Fuel Cell is used as a secondary DG. A storage battery is used as a backup to meet the demand. The microgrid is operated in grid connected mode and islanded mode. The control of DG inverters is based on hysteresis controller. An energy management algorithm is implemented using Kalman filter. A test scenario is presented under different conditions.
