摘　　要：文章建立了基于Copula理论的风光互补配电网经济运行模型,联合配网重构进行求解。分析了风光输出功率以及互补发电模型,考虑了Copula相关性函数对风电和光伏输出功率的影响。说明了风光互补相关性在经济运行联合配网重构优化模型中的应用原理,建立了以网损、运行成本、购电成本等最小为目标的多目标优化模型。提出采用改进的帕累托强度算法(SPEA2)进行求解,在仿真算例中说明了考虑相关性对结果的影响,验证了文章所提模型的有效性。The economic operation model of wind-solar complementary distribution network based on Copula theory is established to solve the joint distribution network reconstruction.The wind and solar output power and the complementary power generation model are analyzed,and the influence of the Copula correlation function on the output power of wind power and photovoltaic power is considered.Explains the consideration method of wind-solar complementary correlation in economic operation joint distribution network reconstruction optimization model,and establishes a multi-objective optimization model with the goal of minimizing network loss,operating cost,power purchase cost,etc.An improved Pareto strength algorithm is proposed to solve the problem.In the simulation example,the influence of whether the correlation is considered on the result is illustrated,and the validity of the model proposed in this paper is verified.
