Intelligent electricity utilization method of household appliances

Abstract

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.

Description

technical field [0001] The invention provides an intelligent electricity utilization method for household appliances, which belongs to the field of intelligent household electricity utilization. Background technique [0002] From 2010 to 2013, millions of smart meters, sensors, and automatic control devices were deployed between the power distribution grid and residential and commercial buildings through communication networks. A variety of retail electricity price schemes, such as real-time electricity price, time-of-use electricity price, and peak electricity price, have been designed and applied to public electricity consumption equipment, so as to encourage users to actively participate in demand response dispatching schemes. In addition, it is also possible to wirelessly control the operating mode and switching status of household appliances through the home energy management system. Electric water heaters, fan heaters, and thermostat settings in air conditioners can b...
