Resilience Assessment and Enhancement Strategies of Transmission System under Extreme Ice Disaster
Ice storm event with high impact and low probability causes a huge challenge to the normal operation of the transmission system. To assess and enhance the resilience of the transmission system under an ice disaster, this paper constructs a resilience assessment and enhancement method for the transmission system. Firstly, the failure rate model of the transmission line is established according to the characteristics of the ice disaster scenario. Then, the resilience assessment metrics are constructed by analyzing the whole process of the system resilience under an ice disaster. On this basis, a resilience enhancement method under the ice disaster is proposed by using the transfer entropy of power flow to screen the lines that need deicing. Finally, the IEEE-30 bus transmission system is utilized to assess the resilience of the transmission system and verify the effectiveness of the proposed resilience enhancement method.
