摘要：
To suppress the voltage fluctuation of DPVG connected in low voltage distribution network, a coordination control strategy of active and reactive power is proposed. According to the equivalent circuit of DPVG connected in low voltage distribution network, the voltage fluctuation mechanism of the grid-connected points is analyzed, and the power adjustment range of the grid-connected inverter is given in combination with the suppression voltage fluctuation requirement. A setting scheme of the inverter PQ reference value is proposed. Combined with PQ power decoupling, the coordination control of active and reactive power is realized. A simulation model is built to verify the coordination control strategy under four weather types such as sunny, cloudy, cloudy and light rain. It is found that the method could effectively suppress the voltage fluctuation of DPVG connected in low voltage distribution network. © 2021, Solar Energy Periodical Office Co., Ltd.
