摘　　要：为考虑分布式电源接入及源荷不确定性对配电网供电单元划分的影响,提出一种考虑模糊机会约束的有源配电网供电单元划分方法。首先,建立考虑分布式电源接入及其不确定性影响的供电单元划分框架;其次,以供电单元数量最少和负荷均衡度最优为目标,建立考虑模糊机会约束的供电单元划分模型;再次,基于模糊变量的清晰等价处理,提出站间站内供电单元迭代求解方法;最后,通过算例仿真对所提出的模型和方法进行说明,并验证其有效性与实用性。To consider the impact of distributed power source integration and source-load uncertainty on the division of supply units in the distribution network,a method that takes into account fuzzy chance constraints is proposed for supply unit division in an active distribution network.Firstly,a supply unit division framework that takes into account the impact of distributed power source integration and its uncertainty is established.Secondly,with the goals of minimizing the number of supply units and optimizing load balance,a supply unit division model that considers fuzzy chance constraints is built.Thirdly,based on the clear equivalence treatment of fuzzy variables,an iterative solution method is proposed for supply unit division between and within stations.Finally,the proposed model and method are explained by calculation example simulation.And their effectiveness and practicality are verified.
