ABSTRACT

With the photovoltaic, fan and other new energy in the proportion of distribution network is growing, the photovoltaic power generation system and the process of accurate simulation is of great significance. Based on Matlab / Simulink, a detailed model of PV array, detailed model of MPPT controller and detailed model of PV inverter control strategy are established according to the actual principle of grid connection, and the process of grid connection of photovoltaic power generation system is simulated. The photovoltaic grid connected waveforms of the mixed-mode simulation system of distribution network of China Electric Power Research Institute are compared with Simulink model simulation waveforms, and the accuracy of the model is verified. The experimental results show that the detailed simulation model of photovoltaic power generation system can accurately re-flect the grid connection process of photovoltaic power generation system.
