Equivalent Demonstration and Clustering Strategy Analysis of Wind Farm

The large-scale wind farm is usually equivalent to a wind turbine to simplify the calculation model of the power system and improve the calculation efficiency. The capacity weighted method is widely used but lacks proof. In order to study the equivalent principle of wind farm, the detailed theoretical derivation and analysis are carried out on the basis of the mathematical model, which provides theoretical support for the capacity weighted method. According to the found equivalent error sources, different clustering strategies are adopted for analysis. The analysis results are verified by simulation.
