分布式储能系统向有源配电网提供的能量平衡和辅助服务代表了一个问题的两个方面，该问题需要根据典型的配电网参数进行适当处理。在此背景下，本文重点研究分布式存储系统的最佳选址和规模的问题。特别是，本文提出了一个问题，帐户的制定：（一）存储系统的电压支持电网，（二）网络损耗和（三）的能量流向外部电网的成本。由于所提出的问题是混合整数、非凸和非线性的，其解决方案需要采用启发式技术。在这方面，提出了一个两阶段的迭代过程。该过程的第一阶段利用遗传算法来提供分布式存储系统的位置和大小;第二阶段通过求解每日AC最优潮流来评估由第一部分提供的解决方案的适合度。一个应用实例，参考IEEE 13总线测试馈线，包括为了证明和讨论所提出的方法的效率。
Energy balance and ancillary services provided by distributed storage systems to active distribution networks represent two aspects of a single problem that needs to be properly treated in view of the typical distribution networks parameters. In this context, the paper focuses on the problem of the optimal siting and sizing of distributed storage systems. In particular, the paper proposes the formulation of a problem that accounts: (i) the voltage support of storage systems to the grid, (ii) the network losses and (iii) the cost of the energy-flow towards the external grid. As the formulated problem is mixed-integer, non-convex and non-linear, its solution requires the adoption of heuristic techniques. In this respect, a two-stage iterative procedure is proposed. The first stage of the procedure utilizes a genetic algorithm to provide locations and sizes of the distributed storage systems; the second stage evaluates the fitness of the solution provided by the first part by solving a daily AC optimal power flow. An application example, referring to the IEEE 13 busses test feeder, is included in order to demonstrate and discuss the efficiency of the proposed method.
