A Resilience-Oriented Incentive Pricing Strategy for Power-Transportation Network Against Flood Hazards

Extreme weather events, such as flood hazards, may superimpose damage on coupled power-transportation networks (PTNs). An effective approach is to guide electric vehicle (EV) owners to enhance grid resilience. However, the EV emergency response and incentive prices are not sufficiently quantified for the post-flood recovery of power distribution network (PDN). Thus, this paper develops a fault scenario generation method to capture the capacity attacks on coupled PTNs during flood hazards. Then, a resilience-oriented tri-level incentive pricing strategy of EV emergency response is proposed for PDN post-flood recovery. At the upper level, EV charging station (EVCS) operators decide incentive pricing strategies for EV emergency response services by assessing the coupled relations of EV discharging/path strategies and PDN subsidy. At the middle level, a modified traffic model is proposed to capture the EV owner’s inconvenience cost associated with emergency response. At the lower level, a resilience metric incorporating EV discharging responses is introduced to mitigate load curtailment of PDN. Furthermore, a decomposition method based on column generation and optimal path set pre-assignment is proposed to address the urgency and destination uncertainty in emergency responses. Numerical results illuminate that the proposed strategy could reduce 41% of the peak load power shedding.
