Abstract

Abstract: To deal with the issue of load resilience enhancement of distribution systems under extreme weather, this paper studied the integrated optimal allocation method of multi energy supply and demand side resources considering the effects of hurricane events. Firstly, the load characteristics of end consumers and the distributed energy resources in the prosumer community were modelled. On this basis, a two-stage robust optimization model was further constructed with the objective of minimizing the cost of multi-energy resources, realizing the emergency optimal allocation of mobile emergency generator(MEG), distributed energy coupling equipment and demand side resources in distribution system. Besides, the impact of hurricane on distribution lines was described via the uncertainty set with adjustable conservative degree. In addition, the column-and-constraint generation (C&CG) algorithm was used to efficiently solve the above model. Finally, the IEEE 33-bus distribution test system was adopted for simulation analysis, and the results show that the comprehensive utilization of multi-energy resources can effectively enhance the load resilience of the distribution systems under hurricane events in a more economical way.

Key words: resilient urban distribution system, demand response, mobile emergency generator, distributed energy resources, two-stage robust optimization
