Abstract Physical test platform is used to verify the function of photovoltaic inverter, but there is a problem that there are few test conditions and can not reflect all kinds of extreme conditions. The hardware-in-the-loop simulation method of digital physics mixture can provide accurate experimental conditions conveniently and with controllable risk and low experimental cost. By studying the electrical characteristics of weak power grid, a hardware-in-the-loop simulation platform of photovoltaic grid-connected system under weak power grid is built based on real time digital simulation (RTDS) system. Low voltage traverse and high voltage traverse tests are carried out based on this platform. By analyzing the simulation results, the feasibility and effectiveness of the simulation method are proved.
