摘要

大量间歇性分布式电源并网可以使配电网在故障时形成计划孤岛，降低配电网运行时的风险。考虑到孤岛形成需要配置新的开关，文中提出一种考虑失负荷风险的配电网光/储与计划孤岛协同规划方法。建立以总成本最少、失负荷风险最低为多目标，电压稳定等为约束条件的规划模型，采用基于非支配排序遗传算法(NSGA-Ⅱ)的多目标进化算法进行求解。规划中考虑了计划孤岛开关的位置与孤岛内光伏、储能电池的选址和定容。以RBTS Bus 6配电系统为例分析了开关配置方案、用户类型对优化结果的影响，结果表明了所提优化模型和方法的有效性。

Abstract

With the high penetration of intermittent distributed generators(DGs)

the distribution network can form a planned island when the fault occurs to reduce operation risks. As successful operation of the planned island needs allocation of new circuit breakers

this paper proposes a coordinated planning method of photovoltaic/battery energy storage and planned island in the distribution network with the risk of lost load taken into account. First

a coordinated planning model is developed with objectives to minimize the total cost and risk of lost load under the constraints on maintaining voltage stability. Then the model is solved by the multi-objective evolutionary optimization algorithm based on the non-dominant sorting genetic algorithm(NSGA-Ⅱ). The location of circuit breakers of the planned island and the siting and sizing of photovoltaic

energy storage battery in the island are considered in the planning. Finally

the influences of the planning programs of circuit breaker and the type of customers are analysed by simulation of RBTS Bus 6 distribution network. The results show the effectiveness of the proposed model and method.
