Abstract: The renewable energy grid integration system in the near area of the solar power and wind power converter realizes at a certain extent the multi-energy complementary under the random fluctuation of renewable energy. However, the intensive grid integration of renewable energy may trigger wide-band oscillations. At present, the converter impedance reshaping is usually used to suppress the wide-band oscillations of the voltage source converter-grid coupling system, only to find that this method has a limited suppression of the high-frequency resonance. A damping complementary control strategy of renewable energy converter is proposed in this paper. Using the complementary characteristics of the solar power and the wind power in the time scale, the solar power and the wind power inverters are respectively reshaped into the active dampers in the intermittent stage. In this way, the damping complementation and the wind-solar energy complementation are both achieved, which suppresses the wide-band oscillations caused by the renewable energy power generation connected to the grid. Finally, the effectiveness of the proposed control strategy is validated by the hardware in the loop based on the RT-Box.
