摘　　要：为了提高综合能源微网的能源利用率和经济效益,结合共享储能服务,考虑风光出力不确定性与相关性,联合共享储能电站服务模式,提出一种兼顾风光出力相关性与共享储能的综合能源微网双层优化模型。上层模型旨在最大化共享储能的服务收益,而下层模型则以降低综合能源多微网系统的运营成本为目标。结合Karush-Kuhn-Tucher条件与大M法将双层优化模型转化为混合整数线性规划问题进行求解。算例验证结果表明,在考虑风光出力不确定性与相关性的基础上,所提出的模型不仅能够提高系统对新能源的消纳能力,而且能够提高系统运行经济性。In order to improve the energy utilization efficiency and economic benefits of integrated energy microgrids with combining with shared energy storage services and considering the uncertainty and correlation of wind and solar output,a dual layer optimization model for the integrated energy microgrid is proposed,which combines the service mode of shared energy storage power stations and takes into account the correlation of wind and solar output and shared energy storage.The upper-layer model aims to maximize the service benefits of shared energy storage,while the lower-layer model aims to reduce the operating costs of the integrated energy multi-mini-grid systems.Combining the Karush-Kuhn-Tucher(KKT) condition with the large-M method,the bi-level optimization model is transformed into a mixed integer linear programming problem for solution.The validation results of the example show that,considering the uncertainty and correlation of wind and solar power output,the proposed model can not only improve the system's new energy consumption capacity,but also improve the system's operational economy.
