A Novel Method of Flexible Transmission Network Planning Based on Set Pair Analysis
Teng Le-tian · Proceedings of the CSEE · 2006
The Set Pair Analysis(SPA)theory to solve the indeterminacy problems in the transmission planning is introduced,and a novel multi-objective flexible transmission network planning model based on SPA is also proposed in this paper.In the object function SPA method is adopted to organically integrate economy and reliability of planning scheme to get the best general benefit of optimal project,and in the restricted conditions certain limited flow overloads of some lines are permitted under “N-1” environments so as to improve its economies.Firstly relative nearness degree is presented to estimate the candidate projects in the relative determinacy conditions,and then relative indeterminacy information is utilized to make both qualitative and quantitative analysis of sequence stability in order to search sequence stability areas and seek other possible sequence results.The sample results indicate that this method is available,efficient,and can provide more information for transmission network planning strategies.
