Self-recovery Scheme and Compensation Mechanism of Distribution Network With Source-load-storage Multi Heterogeneous Distributed Resources
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 par-ticipation of multiple heterogeneous distributed resources was proposed.Firstly,for the power distribution system with mul-tiple 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 evalu-ation was constructed based on node importance and path re-covery time to optimize the recovery path of the unit to be star-ted,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 pro-posed to effectively promote the fair and reasonable distribu-tion 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 alloc-ate restoration resources and improve the speed and stability of power distribution system restoration.
