Intelligent electricity utilization method of household appliances

The invention discloses an intelligent electricity utilization method of household appliances. The intelligent electricity utilization method controls household load strategy based on predicted electricity price and load condition as well as considering user comfort level, so as to satisfy the optimization purpose of maximizing the user comfort level or minimizing electricity expenditure. The intelligent electricity utilization method comprises the specific steps of: collecting load parameters of the household appliances and daily electricity price signals at first, and establishing corresponding load models for the household appliances based on operation rules of different household appliances; then acquiring an optimization model containing constraint conditions according to the acquired preference condition set by the user and the ambient environment temperature changing conditions; and solving the optimization model finally to obtain the predicted optimal operation method of a load and corresponding electricity utilization cost condition. The intelligent electricity utilization method of the household appliances has the advantage of being fast, robust and flexible, and can be applied to a household/building energy management system to help the owner or building managers to create an intelligent electricity utilization strategy automatically according to different electricity utilization costs and comfort levels.
