Application research of super-efficiency DEA method in investment efficiency evaluation of power grid enterprises

Scientific evaluation of the development and operational efficiency of power grid enterprises can clarify the development status of the power grid, promote the improvement of the power grid structure, and achieve the improvement of energy utilization efficiency. This article takes H power grid enterprise as the research object. Based on the analysis of the development status of the power grid, the super-efficient DEA model is used to evaluate the development and operational efficiency of H power grid enterprise from multiple perspectives. Finally, based on the evaluation results, suggestions for power grid planning and development are proposed.
