Abstract: As the global energy and environmental problem becomes increasingly serious, distributed generation based on renewable energy has become the developing focus of many countries. Under the background of the smart grid and growing number of distributed generations, home energy management system(HEMS) as an agent of smart grid will be distributed in various households, which is bound to be vigorously promoted. The intelligent home energy management system and its key technology are introduced in this paper, and a relatively practical topology and its control logic are put forward. Based on this logic, a control method, in which fuzzy control method without additional predictive data is used to optimize the household energy distribution, is proposed in this paper. In the end, the feasibility of this method is verified by real-time simulation.
