Abstract:
Typhoon, as a high-impact and low-probability extreme event, can damage the components in power networks, thereby resulting in power outages or blackouts. To enhance the distribution network resilience against typhoon attacks, this paper proposes a resilience-oriented two-stage robust optimization model, in which resilience-constrained unit commitment schemes and planning-operational restoration measures are incorporated into a prevention and emergency response framework. In the prevention response stage, line hardening, flexible devices deployment, and unit commitment are performed before the typhoon attacks. During the typhoons, the emergency response is conducted to mitigate power outages by regulating soft open points, battery storage systems, and generation units. Moreover, considering the time-varying behaviors of typhoon path, the simulation technique for a sequential typhoon attack is developed to construct the spatially and temporally extended N-k uncertainty set for overhead line status. Thereafter, a tight approximation method is introduced to allow the proposed model to be a tractable mixed-integer linear programming problem, which can be easily solved by a nested column-and-constraint generation algorithm. Numerical results show that the comprehensive resilience-oriented strategies can respond rapidly to the worst-case scenario of typhoon attacks with cost-effective performance. © 2022
