Resilient Electricity Network Recovery Operation Following Seismic Events

Seismic events, globally, are known to impact electricity networks, causing disruptions in the provision of energy and affecting the recovery well-being of communities. Contingency analysis is an established method for understanding network vulnerability, evaluating possible failure situations, and developing specific measures to minimize, which enhance the security of supply. However, current N-1 approaches often fail to effectively handle the dynamic and evolving natures of highimpact natural disturbances. This paper presents modelling based approach illustrated using scenario-based simulations to illustrate network recovery operational planning using contingency analysis. In this study, the N-2 contingency analysis is performed and solutions are proposed to improve the system resilience using the IEEE 39 bus. The identification of potentially viable credible islands is a major contribution of this work.
