利用电参数的工业用户能效模糊综合评估
Fuzzy Comprehensive Evaluation for Energy Efficiency of Industrial Consumers Employing Electric Parameters
摘要
Abstract
It is necessary to accurately evaluate the energy efficiency of an industrial consumer before implementing an energy-saving scheme. Several existing evaluation methods for energy efficiency have some problems such as limited selection of indices, limited access to data and strong subjectivity. Given this background, this paper presents a fuzzy comprehensive evaluation method for the energy efficiency of industrial consumers based on electric parameters. Specifically, the electric parameters are candidate evaluation index, which can be accurately measured and recorded by smart meters. Firstly, we adopt principal component analysis ( PCA) to identify and remove secondary indicators, on this basis determine the comprehensive energy efficiency evaluation index system for industrial consumers. Then, we calculate the weights of all selected indices with using entropy weight method and evaluate the energy efficiency of industrial consumer with using fuzzy evaluation method, considering the exhibited fuzziness of evaluation results. Finally, the actual data from Guangdong province are served for demonstrating the feasibility and features of the proposed method.关键词
