Research and Application of Renewable Energy Panoramic Monitoring Technology

Abstract

With the continuous development of renewable energy power generation and the rapid increase of grid-connected capacity, the impact of its power generation instability on the power system cannot be ignored. Especially under the background of building a new power system based on renewable energy, it is urgent to improve the perception and control level of renewable energy power generation units. At present, the control methods for renewable energy power stations are relatively extensive. Generally, the grid-connected circuit switch of the renewable energy station or the collection circuit switch at the low-voltage side of the transformer is directly turned off, which is likely to cause a large over-cut and increase the workload for re-gridding. At the same time, the supporting capacity of the reactive equipment in the renewable energy station has been lost. The construction and promotion of renewable energy panoramic monitoring system can comprehensively monitor the operation status of renewable energy stations, enable renewable energy stations to participate in the power grid security and stability control in a more flexible way, enrich and improve the security control methods of the large power grid, and reduce the impact of power system faults on the power generation of renewable energy stations.
