In recent years, major power outages caused by extreme natural disasters have incurred large economic losses in distribution systems. This study proposes a transient simulation and verification method for resilience-enhancement strategies and proposed a graphics processing unit-based parallel simulation method. The proposed method can be used to verify the transient feasibility of the distribution system before a strategy is actually executed. Simulations are performed to verify the proposed method.
