Abstract

The structure of large-scale grid-connected photovoltaic system and the control strategy of photovoltaic inverter have been researched. This paper develops the mathematical model of photovoltaic cell array based on physical mechanism. The mathematical model of the photovoltaic inverter and MPPT controller has been established based on incremental conductance method and the inverter controller modeling has been made based on voltage-oriented space vector control scheme. An actual model of a 10 MW PV power plant in Inner Mongolia Province has been built on RTDS digital simulation device. By analyzing the operation of photovoltaic systems with different irradiance and temperature, the simulation results verify the correctness of the simulation model as well as the availability of engineering simulation analysis.
