Micro grids are maturing technically as well as commercially over the past few years. Micro grids are now used for islanded operations where conventional energy sources are not available. This is very helpful to remote mine sites and also for electrifying isolated islands. Maintaining reliability is a crucial matter for islanded micro grids. Hence load and supply balancing is very essential. This paper suggests a prioritized load balancing technique which ensures reliability of service. The loads are studied and prioritized based on which balancing is done. The micro grid is powered by renewable sources like wind energy, solar PV panel and a backup DC generator. This approach always ensures continuity of crucial services while shutting down unnecessary loads during shortage of power. In the advanced stage, in order to improve power quality FACTS devices are installed. Also to harness maximum energy, Maximum power point tracker (MPPT) is installed for wind mill and solar PV panel.
