| 摘要: |
| 针对局域能源互联网发生多故障时的失电负荷快速恢复问题，在考虑交通网与电网信息耦合关系的基础上，提出了一种融合交通网的局域能源互联网多故障修复策略。当局域能源互联网发生多故障时，首先能源路由器将故障信息传递给各虚拟微网；然后，虚拟微网通过控制分布式电源出力，再联合交通网信息对电动汽车进行调度，以优先恢复重要负荷和失电负荷恢复价值最大化为目标制定恢复策略；在此基础上，考虑到微网恢复能力以及电动汽车电池容量限制，当局域能源互联网仍有失电负荷时，结合交通网信息以网损最小为目标优化抢修小队路径，从而实现对关键故障点的抢修，提高恢复效率；最后，以IEEE 69节点系统为例，验证所提策略的可行性。 |

| Abstract: |
| Aiming at the rapid recovery problem of power loss load in case of multiple failures of local energy internet, considering the coupling relationship between the transportation network and power grid, a multi-fault repair and recovery strategy for the local energy internet integrated with transportation network is proposed. When the local energy internet has multiple failures, firstly the fault information is transmitted to virtual microgrids through the energy router. Then, the virtual microgrid controls the distributed power generation, and dispatches electric vehicles in conjunction with the transportation network information to set recovery strategy with priority to restore important loads and maximize the recovery value of power loss load. On this basis, considering the recovery capacity of microgrids and the battery capacity limit of electric vehicles, when the local energy internet still has power loss load, the optimal path is selected for the repair team combined with the transportation network information, so as to repair the critical fault and recover the power loss load as soon as possible. Finally, taking IEEE 69-bus system as an example, the feasibility of the proposed strategy is verified. |
