A method for energy management of household power users

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 a power user energy management method. Background technique [0002] In recent years, the degree of intelligence of household power user terminal appliances has continued to increase, and the number and types have continued to increase, making unified management of smart appliances by power users a real and urgent demand for users. The development of Internet of Things technology and smart home provides many management and control schemes for power users. The functions realized are mainly concentrated in remote control or convenient management, but no effective electrical appliance coordination and energy-saving schemes are provided 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 attention. Therefore, with the help of smart measuring devices in the smart grid and the...

In addition, the vigorous development of renewable energy, home charging vehicles, energy storage and other power terminal appliances has improved the diversification of power supply and brought huge challenges to power users' energy optimization management

[0004] Invention patent CN103413381 A "A Home Energy Management System and Its Work Plan" proposes a home energy control method that requires the user to input a target electricity cost value, which is not the optimal value obtained by the global optimization of the system, so it cannot reach the most economical state

Invention patent CN103676846 A "Intelligent control algorithm for a new type of home energy management system" takes whether the actual electricity demand exceeds the renewable energy generation as the trigger condition for load shedding, and considers whether the user's comfort exceeds the limit, but does not affect the family Effective optimization of electricity costs

Invention patent CN103676846 A "An Intelligent Control Algorithm for Home Energy Management System" adjusts and controls electrical appliances according to the importance of electrical comfort, so as to meet the power limit requirements of power companies. This scheme also cannot effectively reduce household electricity costs. optimization
