A comprehensive evaluation method for economic collaborative planning evaluation of main distribution network based on rough set and scale extension method

Abstract The urban 35kV substation is the link between main network and distribution network, economic power supply site selection optimization are keys to coordinated planning of network. A comprehensive evaluation system established for collaborative from three aspects: social benefit, construction economy, operation combination scale expansion method rough set applied determine combined weight indicators. Based on this index system, a model coordination an intelligent established. It effect company optimal location substations. results show that proposed new grid planning. Under premise ensuring economy reliability supply, level has been significantly improved, better than traditional results. not only expands but also provides guidance
