摘要
随着分布式电源并网容量与出力占比的逐渐提升,配电网的运行迎来较大挑战。对配电网进行合理的区域划分,可以减小配电网管理中所需的计算量,减少内存占有。从结构性和功能性两个角度进行考虑,构建区域划分指标体系,包括区域内耦合度、区域间耦合度、无功平衡度、有功平衡度四项指标,进而建立主动配电网区域划分优化模型。为了提高求解效率,采用基于分解的多目标进化算法(MOEA/D)进行主动配电网多区域划分,对主动配电网区域划分优化模型进行求解。通过算例验证模型的有效性,实现光伏、风电、储能装置等分布式电源的合理配置,并在已有方案基础上实现优化,提高配电网控制、管理、调度的效率。
With the gradual increase of grid-connected capacity and output proportion of distributed power source,the operation of distribution network is facing greater challenge.The reasonable regional division of distribution network can reduce the amount of computation required in the management of distribution network and lessen the memory occupation.Considering from both structural and functional perspectives,a regional division index system was constructed,including four indexes:intra-regional coupling degree,inter-regional coupling degree,reactive power balance degree,and active power balance degree,and then an active distribution network regional division optimization model was established.In order to improve the solution efficiency,the multi-objective evolutionary algorithm based on decomposition was used for active distribution network multi-region division,and the active distribution network region division optimization model was solved.The validity of the model was verified through numerical example,and the reasonable allocation of distributed power sources such as photovoltaic,wind power and energy storage devices was realized,and the optimization was achieved on the basis of existing scheme to improve the efficiency of control,management,and scheduling of distribution network.
