Fault Recovery Strategies for Active Distribution Substation with Distributed Photovoltaic Integration

The study of fault recovery methods for active distribution substations is of significant importance in enhancing power supply reliability and reducing user power outage losses. Incorporating distributed photovoltaic generation into these substations not only enhances outage recovery efficiency but also introduces the risk of secondary outages due to its output uncertainty. To bolster the safety of distributed photovoltaic involvement in substation outage recovery, this paper delves into fault recovery strategies for active distribution substations considering photovoltaic integration. A load recovery model involving photovoltaic participation is formulated, while safety constraints during the grid res-toration process are compre-hensively considered. The model is tackled using the particle swarm algorithm. Simulation outcomes illustrate that, with the integration of distributed photovoltaic generation, not only can safe recovery be achieved while adhering to constraints, but a higher load can also be restored.
