Based on demand response (demand response, DR), a kind of electrical appliances using demand priority evaluation index is established on the premise of DR time electricity requirement. And this paper proposes a smart home based on the theory of fuzzy control strategy. In DR, with electricity price, home appliance sensor and break-time as input, using fuzzy controler to evaluate appliance dynamic priority and generate appliances realize controllable appliances at DR reasonable scheduling priority sequence. The role of different household appliances in improving load curve is analyzed, The simulation results validate the proposed control strategy is effective in DR.
