Resilience improvement strategy of distribution network based on energy storage soft open point combined with network reconfiguration

In response to the shortcomings of traditional tie switches in the face of extreme disasters, this paper proposes a resilience enhancement strategy for distribution network (DN) based on the integration of energy storage soft open point (ESOP) and network reconfiguration. Firstly, the dynamic response process of the distribution network under extreme disasters is analyzed, and the resilience of the distribution network (DN Resilience) is quantified using the total power supply load capacity as a performance metric. Secondly, an operational model for the ESOP is established, taking into account the importance of load. A resilience enhancement model for the distribution network integrating ESOP and network reconfiguration is developed, and the model is solved using second-order cone programming (SOCP). Finally, simulation tests are conducted on the IEEE 33-node distribution network, validating the effectiveness of the proposed strategy in enhancing the resilience of the distribution network.
