Resilience Evaluation of Power-transportation Coupled Network with Electric Vehicles' Restoration Service

Extreme weather events, such as natural hazards, deepen the interaction between the power and transportation network, which underscores the significance of resilience issues for the operation of the two networks, i.e., the power-transportation coupled network (PTCN). Widely distributed electric vehicles (EVs) can provide energy support for the PTCN, which can restore the damaged power network and enhance the resilience performance. The effect evaluation of the PTCN and the EVs' support is fundamental to the resilience enhancement process. This paper proposes a quantified resilience evaluation framework for the PTCN with EVs' participation. The operation modes under normal PTCN, PTCN without considering EVs' mobility and separate operation are analyzed. The traffic flow strategy for EVs during the restoration process of the power network is analyzed. The resilience evaluation of different operation cases is conducted to compare the resilience performances and validate the effectiveness of the proposed operation strategy.
