URBAN MEDIUM-VOLTAGE DISTRIBUTION NETWORK PLANNING BASED ON SPATIAL GIS AND TABU SEARCH
Chengshan Wang · Power System Technology · 2004
Considering the features of spatial data structure in medium-voltage distribution network, the GIS spatial database and planning model suitable to distribution network planning are designed. On this basis and according to the property that the distribution lines are arranged along the streets, the line structure can be represented by length-varying chromosome encoding strategy and the preliminary radial network is formed by the shortest path method. The preliminary network is optimized by Tabu search algorithm. By means of the analysis on actual calculation examples, a practical method for distribution network planning is discovered in which the spatial GIS is used for platform, the distribution network planning is tightly correlated with geographical environment and the search process is guided by TS algorithm.
