Study on Credit Evaluation of Power Supply Company in Power Market Based on KPCA-MEE

doi:10.11930/j.issn.1004-9649.201711287

Abstract

Abstract: Establishing a complete power supply company credit evaluation system is helpful for regulating power market trade and improving the mechanism construction and management level of power market. In this paper, the kernel principal component analysis method and the matter-element theory are combined together to establish a KPCA-MEE power supply company credit evaluation model. Based on the power supply company credit evaluation index system, the KPCA is applied to realize the dimensionality reduction and to determine the index weight. And then the matter-element extension theory is used to describe the process of credit rank evaluation. Finally, based on the data of four power supply companies, a case study is made to verify the validity of the proposed KPCA-MEE model.

Key words: power market, credit evaluation, kernel principal component analysis, matter-element extension, power-retailing company
