Natural disasters have been causing severe power outages in recent years. For example, in 2012, afterHurricane Sandy struck the East Coast of the U.S., approximately 8.35 million customers were reportedwithout power. Hurricane Harvey recently has caused severe power outages in Houston. It dumped anestimated 27 trillion gallons of rain over Texas and Louisiana during a 6-day period. Nearly 300,000customers were without power after Hurricane Harvey hit the coast near the town of Rockport. ERCOTreported the power loss as due to more than 150 damaged transmission circuits. ERCOT oversees 90percent of the state's electricity grid. This presentation will introduce a two-phase mathematical stochasticframework for enhancing the power grid resiliency in the presence of extreme events using defensiveislanding, mobile truck-mounted substation and emergency response generators scheduling during aHurricane. In the first phase, a damage assessment model is presented for detection of possible damagesand doing preventive maneuver action in the grid to minimize the followed damages by Hurricane. Thefirst stage determines the optimal truck-mounted substation and emergency response generators sizes andnumber anticipating, and initial state of the grid defensive topology for an arrival extreme event, and thesecond stage adjusts the truck numbers and grid reconfiguration, if necessary, when the arrival time of thepredicted extreme event becomes closer with updated information. The truck driving paths to feed thetemporary Point of Interconnection (POI) points of the split power distribution grid is generated in thesecond phase while with considering the operation and travel costs (including time) of the truck. Two setsof scenarios are considered for numerical studies from the west area of the city of Houston which wasaffected by Hurricane Harvey in 2017.
