This paper gives a manager of a micro-grid at isolated vicinity the energy is generated by the use of wind and sun based natural energy resources. The main tool that is used for wind energy conversion is doubly fed induction generator (DFIG) and separate battery financial institution is connected to a commonplace DC bus of them. A sun photovoltaic (PV) array is used to convert sun energy that is evacuated at the common DC bus of DFIG the usage of a DC-DC boost converter in a cost effective way.
