Research on Wind Farm Clustering Modeling for Power Grid Dynamic Equivalence

Building a dynamic equivalent model that can accurately describe the dynamic characteristics of power grid with wind farms is the basis of studying the operation and control of power system with high proportion of wind power. In this paper, a practical method of wind farm clustering modeling for power grid dynamic equivalence is proposed. The dynamic equivalence of wind farms is carried out step by step, and the equivalence of clusters, wind farms and networks with multiple wind farms is completed in turn; The calculation formula of aggregate equivalence of parameters of each part is given. The effectiveness of the method is verified by an example.
