[0002] The traditional power supply system is mainly responsible for processing the electric energy output by the power plant and delivering it to the user. The structure of the system is simple. With the development of science and technology, the use of household appliances is becoming more and more frequent. Among them, the power load of high-power appliances such as air conditioners and electric water heaters The rapid growth has had a great impact on the operation of the power grid. Existing technical means are difficult to implement demand-side management. To improve the efficiency of power grid operation, it is necessary to control the increase in user load during peak hours of the power grid by adjusting the power consumption behavior of end users to ensure Safe, stable and economical operation of power grid

[0003] In the process of using electricity, the behaviors that cause energy waste mainly include not effectively managing high-power electrical appliances, not turning off standby appliances, etc. These electricity usage habits not only lead to energy waste, but also bring safety hazards
