针对电力系统中负荷类型多种多样，系统综合负荷模型的组合方案不可能一一列出的问题，提出了一种通过建立负荷模型库，以代表负荷模型投入情况的0－1逻辑变量为决策变量的最优负荷模型自动选择的方法：根据实际电力系统的负荷结构组合出各种动态等值模型，并且在众多模型组合方案中自动选择出最优的模型组合，并将传统启发式算法引入优化求解过程。通过对实际电网动态等值模型的自动选择，得到所选模型组合能够较好的描述负荷行为，表明电力系统综合负荷模型自动选择这一方法的可行性和有效性。

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.
