摘要：
In order to evaluate the risk of power system optimal scheduling brought by wind power over/under-estimation more reasonably and flexibly,and reduce the conservativeness of scheduling decision,a quantitative calculation method of wind power over/under-estimation confidence risk power derivation is proposed based on wind power chance constraints,the transformer ratio regulation and reactive power compensation capacity optimization are introduced into the decision variables,and a multi-objective optimal eco-nomy/risk scheduling model considering wind power confidence risk and source-grid coordination operation is established. A FNSBS(Feasible and Non-dominated comprehensive Sorting Backtracking Search) algorithm is proposed to achieve efficient and accurate solution of the scheduling model. Case results of IEEE 30-bus system verify the effectiveness and superiority of the proposed method. © 2021, Electric Power Automation Equipment Press. All right reserved.
