A Tabu Search Approach for Distribution Network Reconfiguration Based on GIS

Geographic Information Systems (GIS) are designed to support the management, manipulation, analysis, and modeling of spatial data. At present, GIS has been extensively used in the energy management system and distribution management system. It provides visualized platform to electrical distribution system analysis, design and operation, that is, AM/FM/GIS. Once AM/FM/GIS integrate with SCADA, the real time operational data can be displayed in the platform. Distribution network reconfiguration is an important measure for network optimization and loss reduction. Tabu search is a new heuristic searching algorithm which is suitable for solving complex and multiple objectives optimization problem. In this paper, the algorithms used in solving distribution network reconfiguration are introduced. Based on GIS, the distribution network is modeled as geometric network. All electrical distribution system facilities including the network buses, branches, switches and transformers were abstracted into edges and nodes. An improved approach based on TS is presented to match the model. At last, the presented method is validated by typical testing system and some city district electrical distribution system.
