摘　　要：针对区域内新能源场站群联合出力场景的集中式共享储能配置规划问题,提出考虑资源相关性,即风光出力互补特性、各新能源场站出力空间相关性的新能源场站群共享储能优化配置策略。该策略首先利用Copula方法进行典型场景生成,以剖析风光资源的相关性与互补性;在此基础上,建立新能源场站群集中式共享储能的优化配置模型,以实现多主体间储能的共享与互补利用,同时尽可能利用风光资源的相关性。最后通过仿真分析验证所提方法的正确性和有效性。An optimal allocation strategy for shared energy storage systems in a cluster of renewable energy stations is proposed,which considers the complementary characteristics of wind and solar energy and the spatial correlation of the power output of each renewable energy station.The strategy first uses Copula method to generate typical scenarios to analyze the correlation and complementarity of the renewable resources,then establishes an optimal allocation model for centralized shared energy storage systems in the cluster of renewable energy stations to realize the sharing and complementary use of energy storage among multiple entities,while exploiting the correlation and complementarity of wind and solar resources as far as possible.Finally,the correctness and effectiveness of the proposed method are verified by simulation analysis.
