Abstract
The cyber-physical deep coupling makes distribution systems face severe operation risks under small-probability and high-impact disasters. To enhance the resilience of cyber-physical distribution systems against typhoons, this paper proposes a resilience-oriented robust optimization model, in which planning-operational restoration measures are incorporated into a prevention and emergency response framework. In the prevention response stage, line hardening, battery storage systems and soft open point deployment, as well as wireless communication configuration are conducted before typhoons. During the typhoons, the emergency response aims at mitigating power outages by regulating battery storage systems, soft open points, local controllers, and distribution generations. Moreover, considering the time-varying characteristics of typhoon path, a spatially and temporally extended N-k uncertainty set is constructed for overhead line status. Thereafter, the proposed robust optimization model is recast to a mixed-integer linear programming problem, which can be solved by a nested column-and-constraint generation algorithm. Numerical results show that the proposed resilience-oriented strategies can respond rapidly to the worst-case scenario of typhoon attacks with cost-effective performance.
