Research on Control Simulation of Photovoltaic Power Generation System Based on MPPT

Output power of photovoltaic cell will change along with the change external environment and load. In order to give full play to the photovoltaic device efficiency and response external environment change fast, A maximum power point tracking circuit is need to be used. In this paper power voltage curve of photovoltaic cell is analyzed exactly. According to the analyzed results, the fuzzy control is applied into maximum power point tracking control of photovoltaic power generation system. This approach can make system working in the maximum power point without interfering with the normal work of the system. It improves that system stability. The simulation results prove that this approach can track the maximum power point of solar cell quickly and accurately.
