| Abstract: | Taking the physical and mathematical model of photovoltaic cells as the research object, a concise control method of maximum power point tracking （MPPT） with stepless voltage disturbance superposition adaptive based on conductance increment method is proposed by analyzing the output characteristics of photovoltaic cells. In the PSIM simulation environment, it is compared with the conventional fixed step incremental conductance method. The simulation results show that the proposed method can achieve maximum power tracking control quickly and effectively in the case of sudden change of sunlight intensity or load and steady state, which provides a reference for the design and application of MPPT control for photovoltaic power generation. |
