Study on Grid Access of Distributed Wind Power Stations Based on Frequency Control of Two-layer Network
This paper studies the selection of grid access location for distributed wind power sta-tions in a two-layer grid with a communication control layer.The power grid layer adopts the second-order Kuramoto-like model for modeling,and the communication control layer collects the information of the generators and their neighbor nodes to form control signals and adjusts the fre-quencies of the generator nodes.According to the average distance from each load node to the generator nodes of the original grid,three access models of the distributed power stations are de-fined,and the optimal grid access locations for distributed wind power stations with intermittent power fluctuations is studied.Study shows that the synchronization performance and anti-inter-ference ability of the power grid can be effectively improved by adding the frequency control of the two-layer network.In addition,the distributed wind power stations can improve grid stability by selecting load nodes with a small average distance from the generator nodes of the original grid to be connected to the grid.
