Study on the Impact of Large-scale New Energy Power Station on Near-zone of DC Receiving End Power Grid

The impact of the large-scale new energy power station on the near-zone of DC receiving end power grid was studied in this paper. Firstly, the basic situation of the new energy power station and the near-zone of DC receiving power grid was introduced, and the structure of the power grid and installed power supplies in the near-area grid were analyzed. Secondly, the model analysis of thermal power units in the near area and the new energy power station was carried out. Finally, a simulation analysis of the fault recovery capability of the new energy power base connected to the near-zone of DC receiving end power grid based on PSASP was conducted, and it was concluded that the commissioning of Multi-energy complementary megawatt new energy base has no noticeable impact on the voltage recovery capability of the near-zone of DC receiving end power grid.
