Review of Sequential Steps to Realize Power System Resilience

Natural events have been identified as one of the major causes of cascading faults on the electricity grid globally. The impact of these events always brings service interruption in all spheres of life with a high loss of revenue. Natural disasters' attack on the electric grid has defeated the reliability criterion of N-1 recently. A more robust resilience measure is needed to prepare and take proactive decisions based on the predictable natural disaster on the power grid to mitigate the impact of natural events (hurricane, cyclone, ice storm, solar geomagnetic storm, et cetera), and recover fast in case of any contingencies. Achieving a resilient electric grid system involves the use of cutting-edge technological approaches such as microgrids, smart-grid, wide-area monitoring system, and optimal dispatch of repair resources for the reduction of restoration time. While considering how important the research on power system resilience enhancement is, for timely system recovery during a contingency, this paper presents a review of the approaches used to realize power system resilience and suggests a future research area to enhance the power system against natural events.
