Research on Green Performance Evaluation of Distribution Network Material Suppliers Considering Carbon Footprint

Abstract

The green performance evaluation of distribution network material suppliers considering carbon footprint is crucial for promoting low-carbon development in power grids. This paper constructs a comprehensive evaluation system from economic, technical, and green dimensions, defines a carbon footprint accounting method for suppliers, and proposes an improved AHP-SVR evaluation model.Validated on a provincial power box project, the AHP-SVR model achieves a prediction error within ±4.2%, significantly outperforming the traditional AHP method (±8.7%). It also demonstrates superior performance across key metrics—MAE, RMSE, R² and Deviation Rate. The model effectively distinguishes suppliers’ green performance and provides reliable decision support for distributor supplier selection.
