Abstract :
This paper proposes an overall power management control strategy of a stand-alone power supply system consisting of wind turbine and battery storage system. The overall control strategy consists of two layer structure. The upper layer is overall power management controller that generates the reference signal for the local controller. Based on reference signal, the local controllers control the wind energy conversion system and energy storage system. The wind energy conversion system is controlled in order to achieve optimum power from the changing wind. The energy storage system is controlled by a bi-directional dc-dc controller. The performance of the controller is verified in a simulated wind and load conditions and results are presented.
