An Improved MPPT Algorithm for Off-Grid Wind Power Generator Based on Hill Climbing Method

Abstract:

The control algorithm of maximum power point tracking (MPPT) plays a key role in improving the wind energy conversion efficiency. This paper proposes an improved MPPT control algorithm based on hill climbing method, which combines proportional control with hill climbing method, with the advantage of precise steady-state control from hill climbing method, the combination with proportional control enhances the speed of dynamic response. By using this algorithm in the wind power simulation system based on Matlab, we get the simulation results for both fixed and variable wind speed. The result shows that this improved algorithm can track the maximum power point of wind power generation system quickly and precisely.
