Global control method for solar power generation with maximum power point tracking
Solar power generation is easily affected by unstable power grid monitoring equipment and feedback signals,resulting in poor control performance of the solar power generation process and significant power loss when connected to the grid.Therefore,a global control method of maximum power point tracking for solar power generation is proposed.Build the current voltage equivalent mathematical model,analyze the output characteristics of photovoltaic system,and determine the unique point for the maximum power output of the solar power generation system.Use the Boost circuit as the front-end circuit of the maximum power output point to solve the maximum power output point.Quickly track new maximum power points using step size adjustment points to achieve global control of solar power generation.The simulation results show that the maximum power point tracking accuracy of the proposed method is good at different temperatures,and the steady-state generation output power can be achieved in only 1.8 seconds,ranging from 71～73 kW.
