Application Weighted Voronoi Diagrams to Determine the Areas of Responsibility of Transformer Substation, with Accounting Heterogeneity of Load Density

This article deals with the accounting for inhomogeneity of the load density in determining the parameters of the elements of urban power supply systems.In the comparative example shows that accounting load density nonuniformity can more accurately determine the values of these parameters.To determine the optimal location of transformer substations and their areas of responsibility proposed to use multiplicative weighted Voronoi diagrams.The author shows that the distribution of consumers by polygons weighted Voronoi diagrams, in which the force center are transformer stations, reduces density nonuniformity consumer load in the neighboring ranges diagrams and as a consequence, reduction of electric power losses in the power flow between adjacent polygons.
