Finally, according to the content shown in Table VI, the average value is normalized, and the relevant opinions of the two experts are assembled, and finally the ranking vector is V = 0.276,0.252,0.250,0.222 , that is, data risk>credit risk>tax risk>policy risk.

C ONCLUSION A method based on triangular fuzzy numbers for risk factor ranking is used in this paper. This method can effectively compare the severity of settlement risk factors in power market. And analysis results can provide a basis for more accurately and effectively selecting the corresponding control measures in power market. The case analysis in the paper shows that when most of the language fuzzification descriptions are selected during analysis, the values of the four power market settlement risks calculated by the triangular fuzzy numbers are not much different, which indicates data risk, credit risk, tax risk and policy risks significantly affect all the security of power market settlements. The calculation results show that when most of the language fuzzification descriptions are selected, the ranking results are that data risk is greater than credit risk, credit risk is greater than tax risk, and tax risk is greater than policy risk. Therefore, in the power market settlement process, data risk is the most important risk and the one that needs to be controlled most. 17
