Abstract
Considering the order-reduction problem of power system model,an order-reduction method based on proper orthogonal decomposition(POD)is proposed in this paper.First,a systematic sample vector set is established based on a dynamic power system model,and an orthogonal matrixis constructed by using the singular value in a descending order and the corresponding singular value vectors based on the sample vector set.Then,a POD base vector matrixis construct?ed by selecting a parameter that can keep the basic characteristics of the sample set.Finally,based on the base vector matrix,the order-reductionmodel of power system is obtained.The simulation calculation results show that the POD or?der-reduction model can keep the stability of the original system and its dynamic behavior of input/output,which verifi?esthe practicability of the proposed method.关键词
