Study of the Input-Output Overall Performance Evaluation of Electricity Distribution Based on DEA Method

Power is the most important, the most widely used and the most convenient energy in modern society. However, grid system and the scale of construction and operation efficiency research are less coordination. This paper is mainly based on the grid, through the research of grid input-output characteristic, based on which establishing a more objective evaluation system from the economic angle and using the data envelopment analysis to evaluate their relative effectiveness. Finally, through the analysis for grid construction, this paper provides a set of scientific assessment method for the grid construction according to different state.
