Abstract
The disturbance and threat of natural disasters and human attacks often lead to the failure of power system equipment, which will cause large-scale power outages and severe economic losses. Consequently, the research on power system resilience has attracted wide attention. This paper proposes a post-disaster power system resilience enhancement strategy, synthetically considering the failure components repair and power system operation dispatching. According to the damage assessment result, the repair tasks, the unit output and transmission switching plan are formed. Combined with the vehicle routing problem (VRP) and the power system DC power flow model, a mixed integer linear program (MILP) is proposed to minimize the power outage loss and rapidly restore the power supply of load with the minimal repair expense. The proposed model is applied on the IEEE RTS 79 system and verifies its effectiveness.
