The invention discloses a smart home optimization method based on dynamic load management. Based on advanced application methods such as intelligent electric equipment and advanced measuring systems in an existing intelligent power grid, according to factors relating to smart home user comfortableness and the natural environment and factors relating to electricity prices, the operation state of the electric equipment is reasonably arranged and organized, and the electric equipment can operate more efficiently. According to the smart home optimization method, the electric equipment is divided into four types according to the operation characteristics of the electric equipment, and setting of the control state and calculating of electricity cost of the electric equipment are conducted respectively. Through smart homes, the electricity utilization behavior of a user is changed at the appropriate period, and the total electricity utilization cost and the user comfort degree of the electric equipment are used as a multi-objective function to manage the operation state of the equipment. According to the smart home optimization method based on dynamic load management, the weight can be flexibly adjusted according to different demands (minimizing the cost or maximizing the comfort degree) of clients, an optimal objective function is obtained, and equipment operation schemes capable of meeting the various demands of users are obtained.
