A review of resilience enhancement strategies in renewable power system under HILP events

With the increasing attention to residential and industrial electricity reliability, resilience recovery of smart grids under extreme events, such as intentional attacks and natural calamities, has been considered a crucial technology. Power system, integrated with renewable energy, built complex and multielement energy structures to realize low carbon emission and clean. In recent years, there has been a lack of favorable research on resilience under renewable power systems, which is necessary to be sorted out in detail. Thus, this paper address this issue by exploring scientific consensus on principle, and diverse strategies of resilience under the circumstance of conventional and high proportions of renewable energy. It also presents the perspective of a hybrid equipment combination strategy to achieve power system recovery. Finally, this paper expounds on the prospects and opportunities in the context of power system resilience from the viewpoints of existing renewable energy devices and emerging technologies.
