摘要
Integration of wind power generation is increasing rapidly worldwide, hence bringing more challenges to the safe operation of the power system. In this paper, the basic construction method of dynamic security region (DSR) boundary is introduced. A model is established based on DSR, whose object is the minimization of controlling cost in dispatching operations. The coordinated control strategy based on DSR is proposed, with which transient risk assessment of the power system connecting wind farms is studied. The risk indexes calculation and comprehensive analysis method of wind power integration system are defined based on DSR, which can give quantitative indicators to the system day-ahead scheduling plan and present the risk sources as well as weak buses information. Test results on the New England 10-genrator 39-bus system are presented and prove the effectiveness of this approach.
