Modern Electrical Network Restoration Strategy Using Resilience Analysis

Network Restoration following a blackout is a challenging process that faces most network operators from technical, social, and economic points of view. In the case of power grids, economic, social, and political impacts of power system outages will be minimized by using resilience analysis in power system restoration. This paper analyzed the generation/ transmission restoration strategies. The available transmission line paths between the black start units and the nonblack start units are compared based on proposed resilience factors and identified the different resilience paths accordingly. Moreover, comparative performance arrangements of the nonblack start units are analyzed and the best arrangement of the nonblack start units’ restoration based on a proposed resilience metric is determined. The proposed resilience metric is depending on resilience factors and the actual nonblack unit’s starting time. IEEE 24-bus test system is used to assess the proposed resilience method's ability to restore the network rapidly and with high technical performance.
