摘　　要：针对大量分布式电源与储能系统接入电网,为有效对配电网系统进行配置、实现其优化经济运行,提出了配电系统中电池储能系统和分布式发电机的最优配置方法,建立混合整数非线性规划模型并采用规划-运行分解方法进行求解。采用一种定义邻域结构的模拟退火算法,提出分解方法来求解储能系统运行状态问题,以较低计算量来保证近全局最优解。最后,在一个包含230个节点的中低压配电系统上测试了所提出的规划-运行分解方法,利用规划-运行方法进行配置。结果表明,同时接入储能系统和分布式发电并进行合适的配置,其收益较高,虽成本也有所增加,但具有长期收益。同时验证了配置方法的有效性和可行性。For a large number of distributed power generation and energy storage systems connected to the power grid,in order to effectively configure the distribution network system and realize its optimal economic operation,the optimal configuration method of battery energy storage system and distributed generators in the distribution system was proposed,and a mixed integer nonlinear programming model was established and solved by the planning-operation decomposition method.A simulated annealing algorithm that defines the neighborhood structure was adopted,and a decomposition method was put forward to solve the operation state problem of the energy storage system,so as to ensure the near-global optimal solution with low computational cost.Finally,the proposed planning-operation decomposition method was tested on a medium-voltage distribution system with 230 nodes and the planning-operation method is used for configuration.The results show that if the energy storage system and distributed generation are connected at the same time and properly configured,the benefits will be high.Although the cost will also increase,it will have long-term benefits.At the same time,the effectiveness and feasibility of the configuration method are verified.
