Abstract
The types of load model in power system are various, thus the combination of power system aggregate load model can not be completely listed.In view of the above problems, through the establishment of load model library, an automatic selection method of the optimal load model is put forward in this paper, which regards the minimum fit-ting error that represents the proximity of fitting response and practical response as objective function , and put the 0-1 logic variables that represents the investment situation of load model as decision variable.A variety of dynamic e-quivalence models are composed according to the actual power system structure and the optimal model combination is automatically selected.Traditional heuristic algorithm is introduced to optimize the solution process.The effectiveness and feasibility of the proposed method is verified by the automatic selection of the actual power grid dynamic equiva-lent model, and the selected model combination can describe the load behavior well.关键词
