Abstract

Abstract:

Extreme weather brings many challenges to the construction and operation of new power system, and the continuous enrichment of the flexible resources of power system provides the power grid new ideas to deal with extreme weathers. Considering the scenarios of energy storage and other resources aggregation participating in power grid load recovery under extreme conditions, a study is made on the strategy and method for resource aggregation participating in power grid resilience improvement. Firstly, based on the operation status of energy storage resources, a resource surplus adjustment ability model is proposed. And then, a resource aggregation regulation model is established considering the resource surplus adjustment ability, and through "domain" characterization of the correlation between the surplus adjustment ability of resource aggregate and operation power, a power grid optimization operation and resilience improvement model is further built. Finally, the effectiveness of the proposed strategy for power grid resilience improvement is verified through case study.

Key words: energy storage, resource aggregation, residual regulation capacity, resilience improvement
