Effectively deploying renewable power sources can significantly improve the power system restoration efficiency, and their inherent uncertainty should be carefully handled. Moreover, promising research trends are provided to improve the power system restoration with large renewable penetration. 1. Introduction
Conclusion To deal with restoration problems after extreme events, this paper proposed a new restoration strategy considering BSDGs, NBSDGs, SESSs, and the dispatch of MESSs in the transportation system. The MESS as a flexible unit was introduced to mitigate the black start service after events.
Simulation results show that the proposed restoration strategy can perform a successful service restoration under multiple faults and damaged roads with different number of static and mobile energy storage systems while satisfying the network constraints.
