| Abstract: | The perturbation and observation(P&O) method is commonly used in the photovoltaic array maximum power point tracking(MPPT) system due to its succinctness and high tracking efficiency.However,the P&O algorithm can be confused during those time intervals characterized by rapidly changing atmospheric conditions.An improved P&O algorithm by tracking reference signal controlled by DC voltage was proposed.The contrastive simulation results of the improved and conventional algorithm were presented to demonstrate i... |
