【Abstract】 In the photovoltaic power generation system, the traditional maximum power point tracking control method is difficult to satisfy both tracking accuracy and tracking speed. A new improved P&O method combining MPC algorithm was proposed to control MPPT. First, the voltage and the current after the disturbance as parameters were inputted to the MPC controller, and then the two-step function of the controller could predict the action of future variables and generate the output curve. The simulation results show that the algorithm can meet the requirements of both tracking precision and tracking speed comparing with the traditional disturbance observation method.更多还原
