Abstract: The simulation analysis of wind/photovoltaic power generation system has become an important part of the development of renewable energy generation technologies. The critical technologies for wind/photovoltaic power generation system is studied based on real-time digital simulation, and electrical power architecture and communication architecture are built by using real-time digital simulator as a research tool. Each micro-power single control system model is built based on pure software RTDS and micro-power single physical hybrid simulation model, and simulation is analyzed in steady state and dynamic state. The differences between both properties are studied, the validity of the model is proved, and selectable guidance for two models is provided. Conditions of hybrid simulating analysis are close to the actual situation, which not only can both test and debug control strategy performance on the physical platform, but also can correct control parameters and control strategy in real-time, and it provides an important basis for the actual engineering design.
