A New Restoration Strategy in Microgrids after a Blackout with Priority in Critical Loads

The danger of a total blackout in wide area or, even worse, country is always present. restoration methods after mainly focus on the strategy that dispatchers control centers Transmission System Operator will follow than abilities distribution’s microgrids have. This study suggests technique to improve distribution system resilience following blackout, using distributed generation for important loads. goal problem maximize number critical loads are restored catastrophic incident. Under restrictions DGs and network, with good black start capability first. Load weight node importance degree suggested during recovery path selection procedure, while taking topological load into account. A mixed-integer linear program (MILP) used simulate issue, modified IEEE 39-bus test verify efficacy approach.
