A trust evaluation model of electricity customers based on cloud model

In the competitive electricity market, large power customers who consume a large quantity of electricity through the behaviors of malicious arrears of electricity fee and evasion of electricity will seriously affect the normal operation of electricity supply enterprises. Therefore, a trust evaluation model based on the specific characteristics index system of evaluation object' operating environment is constructed, which is based on cloud model, shows experts' opinions with trust vectors. The paper describes the generating method of trust evaluation cloud, and proposes synthetic formula of trust evaluation cloud and decision-making algorithm, which are applied to the trust evaluation of large power customers, provides decision-making basis for the power supply companies choosing trustworthy power customers. Experimental results show that the model is feasible and effective.
