Abstract

A method for planning city electric network based on data envelope analysis includes setting up comprehensive evaluation index set of planned region, dividing planned region to be several sub-regions and selecting a typical one to carry out medium voltage distribution plan, collecting required data as per actual condition and selecting relevant index as input index and another relevant index as output index of data envelope analysis model, using Derfeil manner to carry out qualitative treatment on data and substituting data in DEA model for making decision as per super-efficiency value.

Description

technical field [0001] The invention relates to a comprehensive decision-making method for planning schemes, in particular to the technology of the comprehensive decision-making method for urban power grid planning schemes based on data envelopment analysis. Background technique [0002] Urban power grid is one of the important infrastructures of urban modernization and an indispensable energy supply system for modern cities. The scheme formed in urban power grid planning is actually a possibility of investment. Due to different planning principles, technical routes, power point selection, environmental protection, operation and maintenance, equipment status, capital composition, construction period, etc., urban network planning will form many different planning options. Today's urban power grid planning is an uncertain, complex, multi-objective and nonlinear decision-making process. The decision-making of traditional urban power grid planning schemes pursues a single goal...
