A Review of Smart Grid Restoration to Enhance Cyber-Physical System Resilience

The growth in electricity demand and the development of grid modernization have increased the complexity of power grid and driven the grid more vulnerable to extreme events like environmental disasters or man-made attacks. Those disruptions can cause outages, cascading failures, and blackouts. The objectives of this paper are to 1) review the recent development addressing the aforementioned challenges with the focus on the impact of extreme events on power system resilience, and 2) discuss the application of smart grid technologies to provide faster restoration techniques and enhance power system resilience. Moreover, challenges and opportunities for future work to enhance smart grid resilience have also been discussed in this paper. The ultimate goal is to present a summary of state-of-the-art and stimulate interests in the area of cyber-physical- human resilience of smart grid.
