“源-荷-储”多异质分布式资源参与配电网自我恢复方案与补偿机制

Self-Recovery Scheme and Compensation Mechanism of Distribution Network with "Source-Load-Storage" Multi Heterogeneous Distributed Resources

  • 摘要: 为应对新型电力系统所面临的大停电风险,从“源-荷-储”多环节挖掘分布式资源参与配电网恢复的潜力与价值,制定安全、快速的恢复方案成为必然需求。为此,考虑多时间尺度下的黑启动恢复过程对灵活性需求的不同,提出了一种考虑多异质分布式资源参与的配电网自我恢复方案。首先,针对含有多类型分布式资源的配电系统,以最大化可用发电量和有功负荷恢复量为目标,构建分布式资源启动顺序优化模型;其次,基于节点重要度和路径恢复时间,构建综合路径评价指标,实现待启动机组的恢复路径优化,进而分时步投入停电负荷以降低停电损失;第三,考虑恢复过程中的分布式资源黑启动能力与使用度,提出包含能力补偿费与使用补偿费的黑启动激励机制,有效促进服务费公平、合理分配;最后,以改进的IEEE33节点系统为例,通过多个停电场景分析证明,所提方法可有效调配恢复资源,提升配电系统恢复的快速性与稳定性。

     

    Abstract: To cope with the blackout risk of the new power system, it is an inevitable requirement to explore the potential and value of distributed resources participating in distribution network recovery from the multiple links of "source, load and storage", and work out a safe and fast recovery plan. For that reason, considering the different flexibility requirements of the black-start restoration process under multiple time scales, a self-restoration scheme of distribution network considering the participation of multiple heterogeneous distributed resources was proposed. Firstly, for the power distribution system with multiple types of distributed resources, an optimization model of the start-up sequence of distributed resources was constructed with the goal of maximizing available power generation and active load recovery. Secondly, a comprehensive path evaluation was constructed based on node importance and path recovery time to optimize the recovery path of the unit to be started, and then the outage load was put into operation step by step to reduce the outage loss. Thirdly, considering the black-start capacity and utilization of distributed resources in the recovery process, a black-start incentive mechanism including capacity compensation fee and utilization compensation fee was proposed to effectively promote the fair and reasonable distribution of service fees. Finally, taking the improved IEEE33 node system as an example, the analysis of multiple power outage scenarios shows that the proposed method can effectively allocate restoration resources and improve the speed and stability of power distribution system restoration.
