Leveraging Electric Vehicles to Enhance Resilience of Interconnected
Power-Transportation System Under Natural Hazards
Abstract
The rapid development of transportation electrification brings about the
popularity of interconnected power-transportation systems (IPTS).
However, the escalating frequency and uncertainty of natural hazards,
such as typhoons, pose threats and potential damage to the operation of
IPTS. Electric vehicles (EVs) can serve as mobile energy sources, whose
proper scheduling in transportation networks can provide power support
for the damaged power networks caused by natural hazards, thus enhancing
the system’s resilience. This paper proposes a two-stage scenario-based
scheduling framework using EVs for the restoration of an IPTS under
natural hazard risks. In the first stage, EVs are pre-allocated and
pre-charged at the charging stations to maximize their support potential
against the predicted hazards; in the second stage, EVs are
re-dispatched among different charging stations to help restore the
power demands given the damaged IPTS topology. To address the real
hazard scenarios and reduce the computational burden, a scenario
generation approach indicating the real hazard’s impact on the IPTS is
proposed followed by a scenario-reduction algorithm. Numerical
experiments are conducted to validate the effectiveness of the proposed
method based on the IEEE 33-bus distribution network and the Sioux Falls
transportation network.
