摘要：
Typhoons are prone to cause large-scale power outages that result in large economic losses. This paper investigates the power grid resilience assessment and differentiated planning methods against typhoon disasters. First, based on Batts wind field simulation, a fault recovery model for transmission lines is constructed, and a resilience assessment index is proposed considering the supply of critical load. Then, a two-stage optimization model for differentiated planning is constructed, in which the first stage optimizes the line reinforcement strategy based on the differentiated planning scheme. In the second stage, the resilience enhancement effect of the planning scheme is further verified by optimizing the load recovery strategy supported by energy storage. Finally, the solution is performed by the particle swarm optimation algorithm with elliptic function modified inertia weights. The effectiveness of the proposed method is verified by simulation results. © 2023 Automation of Electric Power Systems Press. All rights reserved.
