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.
