Intelligent control method and system for interactive home appliances on basis of time-of-use electricity price response

Abstract

The invention provides an intelligent control method and system for interactive home appliances on the basis of time-of-use electricity price response. The method is characterized by comprising the steps that the home appliances are automatically classified according to types of home appliance loads; use habits of the home appliances of users are determined according to historical home appliance running status data collected in 30 days; according to time-of-use electricity price policy information of a receiving power grid, basic load demand ranges corresponding to all time periods are predicted and determined for the users; according to obtained user home appliance use habit characteristics and load settings, controllable degree indexes of the home appliances are calculated, and running status models of the home appliances are determined; according to the controllable degree indexes of the home appliances, dynamic control priorities and a control algorithm of the home appliances are determined, and intelligent control over the home appliances is achieved. The method and system have the advantages that interactivity is good, the receiving degree of the users is high, the users can be guided to reasonably avoid the peak hours for electricity utilization, and electricity utilization cost is remarkably reduced.

Description

technical field [0001] The invention relates to the field of home appliance intelligent control, and relates to an interactive home appliance intelligent control method and system based on time-of-use electricity price response. Background technique [0002] With the rapid development of smart grid, household users have more smart home appliances, and the load of home appliances continues to increase. In order to reasonably reduce electricity consumption and scientifically guide users to cut peaks and fill valleys, intelligent control of home appliances is imperative. At the same time, smart The emergence of two-way interactive technology and demand response technology makes it possible for users to actively participate in time-of-use electricity price response by controlling home appliances. [0003] At present, the home intelligent control methods include: Chinese invention patent application number: 201110044875.8, which discloses a method, device and intelligent home app...

Problems solved by technology

It extracts the narrowband power line carrier communication PLC signal from the power grid, then converts the PLC signal into a logic level TTL, determines the current power grid electricity price information according to the converted logic level TTL, and then converts the electricity price information into The control command corresponding to the electrical appliance is finally sent to the electrical appliance through the control interface of the electrical appliance to achieve the function of controlling the electrical appliance. However, it only considers the influence of the power grid load change factor on the control of the household appliance, and ignores the user's electricity consumption habits and distribution. Timely electricity price response and satisfaction and other factors, the control process is not humane enough, it has a great impact on the normal life of users with electricity, and the degree of user acceptance is limited
