Abstract
A new numerical control and optimum gradient method is proposed. This method can track MPPT changes rapidly when the external environment changes rapidly, at first, it can mostly track the MPP based on numerical control method, and then on this base it can track the MPP rapidly and accurately. Simulation and research show that this method has good transient characteristics and it also reduce the power oscillation around MPP.
