【 摘 要 】

According to the characteristics of the development of regional power grid, the regional power grid evaluation system is studied and explored as viewed from the power grid input-output. Using data envelopment analysis method and taking the power grids with 220 kV∼110 kV and 35 kV and below as objective respectively, the input-output evaluation model is established. Through the comprehensive efficiency analysis and projection analysis, the grid efficiency value based on the inputs and outputs, the gap between non-effective unit and the target value and other information elements are obtained, which comprehensively evaluates the input-output efficiency of the regional power grid. It provides a scientific decision support for optimizing the allocation of resources and improving the efficient use of resources, which is conducive to promoting the coordinated development of power grids at all levels. The results of calculation examples demonstrate the effectiveness of the proposed method.
