Research on Black Start Scheme of Distribution Network Based on Multi-type Distributed Resources

With the "carbon peak, carbon neutral" energy strategy goal, accelerate the construction of new energy-based power system has become the development value direction of China's energy field for a long period of time in the future. In order to cope with the risk of blackout in the new power system, it is necessary to explore the potential and value of distributed resources in blackout from "source-load-storage" and develop a safe and fast blackout recovery plan. Considering the black start process in the complete time scale, a self-recovery scheme for distribution network based on multiple types of distributed resources is proposed in this paper. Firstly, considering the distribution system containing multiple types of distributed resources, a distributed resource start-up sequence optimization model is constructed for different types of power sources with the objective of maximizing the available generation capacity and active load recovery, and then the outage load is input in time steps to minimize the outage loss; secondly, considering the black-start capacity and utilization in the restoration process, a distribution network black-start incentive mechanism including capacity compensation fee and utilization compensation fee is proposed to effectively promote the black-start Finally, taking the improved IEEE33 node system as an example, the analysis of multiple outage scenarios shows that the proposed method can effectively deploy restoration resources and improve the rapidity and stability of distribution system black start.
