From the user's perspective,this paper constructs an optimal smart power consumption model of residential users by considering the satisfaction in the process of utilizing electricity. First,the characteristics of intelligent electric appliances are analyzed,and the operation constraints of non-interruptible and interruptible appliances are established. Meanwhile,the satisfaction of residential users in the process of utilizing electricity is defined according to their requirement for comfort. In order to distinguish users' preference for different electric appliances,the non-scheduling coefficient is introduced into the constructed model and is solved by means of the analytic hierarchy process. Finally,a simulation in the NYISO real-time pricing environment is conducted. The results show that the optimized consumption strategy can satisfy users' electricity demand and cut down their electricity bills.
