基于集群划分的配电网多时间尺度分布式有功-无功协同优化方法
Multi-timescale distributed active and reactive power coordinated optimization method of distributed network based on cluster division
Large scale distributed generation (DG) connected into the distribution network (DN) increases the difficulty of DN to cope with the uncertainty and centralized control. Therefore, this paper proposes a multi-timescale distributed active-reactive coordinated optimization method based on DG cluster (DGC) of DN. At the day-ahead level, a centralized active-reactive power coordinated optimization model is established to arrange the power and start-stop plan of long-time adjustment equipment. Then, considering the influence of DG and load forecast errors on voltage, a DGC cluster partition model is established based on day-ahead scheduling result. At the intraday level, targeting the minimum of optimal cost and voltage deviation, a distributed active-reactive power coordinated optimization model is established based on DGC and SADMM, to revise the day-ahead power plan of each continuous adjustment equipment. Finally, taking the IEEE33-node system as an example, the effectiveness of the proposed method is verified.
