Fault Reconfiguration in Distribution Networks through Multi-Energy Cooperative Networks

This paper develops a novel configuration for fault recovery in a distribution network by implementing a multi-energy cooperative energy network. The interconnected energy subsystems enable a coordinated response to system disruptions, leveraging coupling elements. Upon active network segmentation of the distribution network, the system transitions to an islanded operational mode, with distributed generation (DG) supplying power to each island. Simultaneously, parts of the loads are reconfigured as non-electrical systems, facilitating the transfer of energy across different forms. Coupling elements, such as gas turbines and combined heat and power (CHP) units, enhance electrical output, contributing crucial support for the network. These elements play a pivotal role in restoring energy supply and directly influence the effectiveness of the recovery process. The innovation significantly enhances the resilience and reliability of distribution networks, offering a robust solution for modern energy systems.
