Enhancing Resilience of Distribution Systems Considering Electric Vehicles and Network Reconfiguration in Post-Extreme Events

After extreme events, the uninterrupted power supply to critical loads in the distribution network faces significant challenges. Electric vehicles (EVs), as mobile energy storage units, can supply power to the distribution network through Vehicle-to-Grid (V2G) technology, assisting in the restoration of the distribution network after outages. A collaborative fault restoration strategy is proposed considering the spatiotemporal distribution of EVs supplying power to the distribution network, while also considering the network reconfiguration strategy of the distribution network. The probability of EVs selecting V2G stations and the energy distribution of EVs are characterized. Based on this, a collaborative load restoration strategy considering network reconfiguration of the distribution network is constructed, and the model is formulated as a mixed-integer second-order cone programming (MISOCP) problem. Finally, a case study is conducted using the IEEE 33-node distribution network configuration to verify that the proposed strategy can enhance the load restoration capability in extreme scenarios.
