In this paper an integrated system of WECS, battery storage and controller is proposed to supply electrical energy to a small community in a remote area in Egypt. The layout and the configuration are presented and discussed. Also, a new wind speed frequency distribution model is proposed based on the prevailing wind speed in this area. The validity of the model is tested for different sites in Egypt. The model and the relevant equation express the wind speed frequency distribution in terms of the prevailing wind speed in the site and it frequency distribution, hence it can be applied for any site all-over the world with known wind speed profile. Based on this model, the size and rated speed of the WECS to provide electrical energy to the specified loads in this remote area can be determined.
