Impact of Microgrid towards Power System Resilience Improvement during Extreme Events

Microgrids are considered a promising alternative for handling significant power-disrupting incidents due to their islanding capabilities and the potential to support renewable energy penetration. A two-stage analysis is conducted in this review paper to explain the impact of microgrids in increasing the resilience of the electrical network. In the initial stage, resilience-based modeling methods are presented based on microgrid resilience strategies utilized during various phases of severe disasters. In the next stage, the use of microgrids as a resilience resource is analyzed by building self-sustaining microgrids. The formation of dynamic and interconnected microgrids and the coordination of various energy networks are also investigated. In addition, the importance of the resilience of communication networks to improve microgrid resilience is analyzed. Finally, the research gaps in the existing literature are presented, along with the prospects to enhance the extant resilience-based operating approaches to increase microgrid resilience.
