Abstract：This paper studies the selection of grid access location for distributed wind power stations 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 frequencies 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 defined, 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-interference 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.
