Analysis of Evaluation Model of Power Grid Energy Conservation Based on Improved Entropy TOPSIS Method

摘要

With the energy shortage，energy efficiency level of the power grid is playing an increasing role on sustairIable development of power grid and the steady growing of the national economy．In this paper according to analysis of energy-saving nature of Chinese power grid，a comprehensive，scientific and practical indcx system of energy-saving nature of Chinese poWer grid is proposed．The syrstem is constructed from the generation side，the transmission side，the distribution side and the power side,and improved entropy method is used to determine the weight．In the Paper，power grid energy-saving evaluation model based on improved entropy-based TOPSIS method iS established to comprehensively evalnate the energy conservation．Finally, data from five regions is used to empirically analyze the model．
