【摘要】：针对主动配电系统中分布式电源(DG)和负荷的不确定性特点,提出了适用于配电网的线路潮流介数的概念,并将其应用于软常开开关(soft normally open points,SNOP)的配置分析。在此基础上,将SNOP优配置与配电网重构相结合,以网络损耗和电压偏差最小为目标,建立了配电网联合优化运行模型。该模型可以实现配电网多时间尺度上的全面优化,不仅能保证SNOP输出功率具有一定的裕度而且可以减少重构动作次数。以改进的IEEE33节点系统为例,进行了SNOP的优化配置分析、SNOP和重构联合优化性能分析及短时动态调整分析,验证了所提SNOP配置原则和联合运行优化策略的可行性和有效性。
[Abstract]:In view of the uncertainty characteristics of DG and load in active distribution system, the concept of line power flow medium for distribution network is put forward, and it is applied to the configuration analysis of soft normally open points and SNOP. On this basis, the SNOP optimal configuration is combined with the reconfiguration of distribution network, and the joint optimal operation model of distribution network is established with the goal of minimum network loss and voltage deviation. The model can realize the overall optimization of the distribution network on multiple time scales, which can not only guarantee the output power of SNOP with certain margin, but also reduce the number of reconfiguration operations. Taking the improved IEEE33 bus system as an example, the optimal configuration analysis of SNOP and reconfiguration combined optimization performance analysis and short-term dynamic adjustment analysis are carried out. The feasibility and effectiveness of the proposed SNOP configuration principle and joint operation optimization strategy are verified.
