Cluster Analysis of Grid-Connected Large Scale Wind Farms
摘要
Abstract
A cluster grouping algorithm for grid-connected wind farms based on transient voltage characteristics at the connecting point is proposed, namely according to the different impacting extent of system faults on grid-connected wind farms the wind farm groups with similar dynamic behavior are identified, and further the coordinated control of wind farms in the same group can be implemented. To validate the effectiveness of the proposed algorithm, a simulation model of West Jilin power grid is built by advanced visualization sotiware Powerworld and study of cluster analysis is performed. Simulation results show that the calculation results by the proposed algorithm are relatively stable, besides the proposed algorithm possesses a certain function of dynamically identifying grid-disconnected wind farms.关键词
