摘要：

The real-time pricing mechanism is an ideal method of the smart grid in the future. Based on the social welfare maximization model, the real-time pricing strategy of smart grid is studied in this paper. According to the working characteristics of appliances, appliances are divided into three categories, which are must-run appliances, elastic appliances and semi-elastic appliances. For the coupling property about time of power consumption of elastic and semi-elastic appliance, a multi-time slots model is established. The multi-time slots model is decomposed into a set of single-time slot optimization problems by the relaxation method. Based on the theory of duality, a distributed algorithm is proposed. The real-time electricity price is obtained. In this algorithm, users do not need to disclose their specific power consumption information to the energy suppliers and other users, which protects users' personal privacy. Numerical simulation verifies the rationality of the model and the effectiveness of the algorithm. © 2019, Editorial Board of Journal of Systems Engineering Society of China. All right reserved.
