摘　　要：在微电网集成配电系统中集成可移动式储能有助于改善配电系统的运行性能。针对微电网内部可移动式储能的最优分布及系统结构调整后对系统运行特性的改善进行了研究。首先,针对系统中分布式电源的发电特性,考虑其能量管理的作用,构建了数学模型;然后,提出了可移动式储能优化分布和系统重构的目标函数及系统特性评估指标;最后,采用了PG&E69总线配电系统进行了仿真和案例研究,并使用基于启发式的粒子群优化算法来寻求最优解。仿真结果表明,在可移动式储能最优分布和系统结构的重新调整后,配电系统的运行特性得到了显著的提升。Integrating mobile energy storage in microgrid integrated distribution systems can help improve the operational performance of distribution systems.A study was conducted on the optimal distribution of mobile energy storage within microgrids and the improvement of system operating characteristics after system structure adjustment.Firstly,a mathematical model was constructed by targeting the distributed power generation characteristics in the system and considering the role of energy management;then,the objective function and system characteristic evaluation indicators for optimizing the distribution and system reconstruction of mobile energy storage were proposed;finally,simulation and case studies were conducted using the PG&E69 bus distribution system,and a heuristic based particle swarm optimization(PSO)algorithm was used to seek the optimal solution.The simulation results show that after the optimal distribution of movable energy storage and the restructuring of the system structure,the operational characteristics of the distribution system have been significantly improved.
