大规模分布式光伏等分布式电源接入电网增大了配电网对调度灵活性的需求及传统集中调控模式的难度。为此,提出一种考虑配电网灵活性供需鲁棒平衡的两阶段日内分布式优化调度方法。第1阶段,考虑净负荷不确定性与配电网灵活性供给能力,提出分布式电源集群的灵活性供需鲁棒平衡指标,并结合模块度指标建立了配电网分布式电源集群划分模型;第2阶段,根据配电网分布式电源集群划分结果,建立适用于分布式电源集群的日内分布式优化调度模型,并采用同步型交替方向乘子法进行了求解。最后,以IEEE 33节点系统为例验证了所提方法的有效性。
The access of large-scale distributed generators (DGs) such as distributed photovoltaics to the power grid increases the demand for dispatch flexibility of distribution network and the difficulty of traditional centralized control modes. Therefore
a two-stage intraday distributed optimal dispatch method for the distribution network considering the robust balance between the flexibility supply and demand is proposed. In the first stage
considering the uncertainty of net load and the flexibility supply capacity of the distribution network
a robust balance index on the flexibility supply and demand of DG cluster (DGC) is proposed
and a DGC partition model of the distribution network is established combined with the modularity index. In the second stage
according to the DGC partition results
an intraday distributed optimal dispatch model suitable for DGC is established
and a synchronous alternating direction method of multipliers (SADMM) is used to solve this problem. Finally
the effectiveness of the proposed method is verified by taking the IEEE 33-bus system as an example.
