Abstract: In this paper proposed result analysis of control scheme for a stand-alone wind energy conversion system. Wind energy conversion system (WECS) is nowadays deployed for meeting both grid-connected and stand-alone load demands. However, wind flow by nature is intermittent. In order to ensure continuous supply of power suitable storage technology is used as backup. In this paper, the sustainability of a 4-kW hybrid of wind and battery system is investigated for meeting the requirements of a 3-kW stand-alone dc load representing a base telecom station. Present energy want greatly depends on the quality sources. But the inadequate accessibility and steady increase inside the value of typical sources has shifted the main focus toward renewable sources of energy.

Keywords: Maximum power point tracking (MPPT), pitch control, state of charge (SoC), wind energy conversion system (WECS).
