Active Support Strategies for Power Supply in Extreme Scenarios with Synergies Between Idle and Emergency Resources in the City
There are numerous idle electric vehicle (EV) resources in urban distribution networks, which hold significant potential for emergency power supply support following network failures. Based on this, a proactive power supply support strategy is proposed, integrating urban idle resources and emergency...

| description | There are numerous idle electric vehicle (EV) resources in urban distribution networks, which hold significant potential for emergency power supply support following network failures. Based on this, a proactive power supply support strategy is proposed, integrating urban idle resources and emergency resources under extreme scenarios. First, an emergency dispatch model is established for EVs in public parking lots and electric power supply vehicles (EPSVs), considering the impact of road congestion. Next, the costs of various emergency resources are analyzed, and a multi-source collaborative power restoration strategy is proposed. This strategy includes EPSVs, EVs, photovoltaics, line repair teams, and other resources, with load shedding loss costs incorporated into the optimization framework. Finally, the proposed strategy is validated through simulations using an IEEE 33-node distribution network and a 32-node transportation network. The results demonstrate that the line topology of the faulty distribution network is restored to normal after the repair team’s intervention. Moreover, the strategy enables efficient utilization and economic dispatch of urban idle and emergency resources while improving system reliability. |
