DYNAMIC RECONFIGURATION OF DISTRIBUTION NETWORKS CONSIDERING THE REAL-TIME TOPOLOGY VARIATION
Network reconfiguration is a vital analysis process for optimizing and controlling distribution systems (DSs). Under normal operating conditions, active losses of the network are reduced to balance the load of the system fades. Given a stable initial DS, the distribution feeders can be reconfigured by changing the status of the switches to improve the operational performance. Owing to the fault trip, equipment maintenance, and system extension, the removal or addition of a branch can change the structure of the initial topology. This project proposes a dynamic reconfiguration method that considers the real-time initial topology variation. The method combines the dynamic topology analysis with network reconfiguration to address the optimization problem of the real-time distribution network. A set of independent topological parameters represents the initial topology of a DS. After the changes in the initial topology are detected, the dynamic topology analysis is used to restore network connectivity and identify out-of-service areas. Then the real-time initial topology is obtained by updating the topological parameters. In accordance with network reconfiguration, the optimal configuration is identified to reduce power loss and improve the voltage profile of the real-time distribution network. The design is tested in IEEE-33 and 118 Bus System to verify the effectiveness of the proposed method.
