Review of Research on Resilience of Distribution Network with Massive Resources Considering Uncertainty Disturbance

  • 摘要: 分布式电源、微电网、储能装置等海量灵活资源接入配电网使得弹性配电网成为可能。然而,上述资源在协同抵御外界冲击、恢复电网正常运行方面的潜力有待进一步挖掘。配电网中,海量资源的时空深度耦合使得其结构与控制日趋复杂,源网荷任意侧的波动都可能引发连锁故障,影响配电网安全运行。为此,文中提出考虑不确定性扰动的含海量资源配电网弹性研究框架,将抵御外部灾害与平抑内部波动纳入研究范畴。首先,拓展配电网弹性内涵,总结配电网现有灵活资源,提出含海量资源高弹性配电网结构并对其特征进行分析;其次,分别从静态拓扑与动态响应角度提出结构弹性指标、系统弹性指标实现定量分析;然后,将不确定性扰动划分为外部冲击与内部波动,并提出配电网弹性研究框架,对其数据基础、理论支撑与弹性提升技术、应用场景进行了详细梳理与讨论;最后,对含海量资源高弹性配电网进行了展望。

     

    Abstract: The access of massive distributed generators,microgrids,energy storage devices,and other flexible resources to the distribution network makes a resilient distribution network possible.However,the potential of these resources in cooperatively resisting external shocks and restoring the normal operation of the power grid needs to be further explored.The deep spatialtemporal coupling of massive resources makes its structure and control more and more complex in the distribution network.Fluctuations on any side of the source-grid-load can trigger chain failures and affect the safe operation of the distribution network.For this purpose,this paper proposes a resilience research framework for the distribution network with massive resources considering uncertainty disturbances.The framework incorporates resilience to external hazards and suppression of internal fluctuations into the research scope.Firstly,this paper expands the connotation of distribution network resilience,summarizes the existing flexible resources of distribution networks,proposes the structure of a highly resilient distribution network with massive resources,and analyzes its characteristics.Secondly,structural resilience indexes and system resilience indexes are proposed from static topology and dynamic response perspectives respectively to realize quantitative analysis.Then,the uncertainty disturbance is divided into external shocks and internal fluctuations.And the research framework of distribution network resilience is proposed.Its data foundation,theoretical support and resilience enhancement technology,and application scenarios are sorted out and discussed in detail.Finally,an outlook on the highly resilient distribution network with massive resources is presented.
