Household power consumer energy management method

Abstract

The invention provides a household power consumer energy management method. The household power consumer energy management method comprises the following steps: firstly dividing common household electric appliances into three types according to operation characteristics of different electric appliances, namely a non-thermal control non-interruptible electric appliance, a non-thermal control interruptible electric appliance and a thermal control electric appliance; defining a target optimization function J of a power consumer energy management optimization module weighted by a user dissatisfaction penalty function J2 and a target optimization function J1 for the daily electric charge of a household power consumer; as for a piecewise function describing the dissatisfaction of the thermal control electric appliance, introducing a nonnegative number, 0 and 1 to linearly express the piecewise function; determining different restraints to be met by the target optimization function J, acquiring data needed for a power consumer energy management optimization model; using a CPLEX solver to solve a target function of the power consumer energy management optimization model; acquiring optimization results like an estimated electric charge for the day, estimated operation time frames and starting and stopping moments of the electric appliances, and feeding back the results to a consumer through a human-computer interaction interface.

Description

technical field [0001] The invention relates to an energy management method for power users. Background technique [0002] In recent years, the degree of intelligence of household electric power user terminal appliances has been continuously improved, and the number and type of electric appliances have continued to increase, making the unified management of intelligent electric appliances by electric power users a real and urgent demand of users. The development of the Internet of Things technology and smart home has provided many management and control solutions for power users, and the functions implemented are mainly concentrated in remote control or convenient management, without providing effective electrical appliance coordination and energy-saving solutions for power users. [0003] With the development of smart grid technology, reducing the cost of power supply and demand balance through the demand side response of end power users has gradually attracted people's att...
