Problems solved by technology

[0003] The current research on how residential users participate in demand response either only considers the demand response scheduling problem of part of the load in residential users, and cannot fully tap the controllable resources on the user demand side; or establishes an accurate and complex electrical energy consumption description model With the scheduling strategy, it takes a lot of calculations to get the scheduling result

Abstract

The invention discloses a power demand response control system and method, and the system comprises a controller and intelligent sockets disposed at positions of all users. Each intelligent socket is configured to achieve the start / stop control of an electric appliance, the current data collection and the transmission of current data to the controller. The controller is used for building a relation model of a corresponding period power consumption quantity and the working time according to the load type of each electric appliance in the house of a user, determining the operation time of the electric appliance through combining the electricity charge of each time period and taking the minimum electricity expenditure as the precondition, formulating an electric appliance control strategy, transmitting the electric appliance control strategy to the intelligent sockets, and enabling the user to automatically participate in the demand response based on time-of-use electricity price. The method is small in calculation burden, is easy to implement in a common embedded controller, and is higher in practical value.

Description

Technical field [0001] The invention relates to a power demand response control system and a load control method thereof. Background technique [0002] As the electricity consumption of residential users increases year by year, the peak-to-valley difference of power load gradually increases, which is not conducive to the economic operation of the power grid. To solve this problem, electricity demand response projects based on time-of-use electricity prices have been widely implemented. However, due to the lack of a demand response controller that can operate automatically, and the timeliness and urgency of residential load electricity consumption, residents are unwilling to adjust the running time of electrical appliances and reduce electricity costs even if electricity costs are high most of the time . Therefore, it is necessary to design demand response controllers for residential users and promote their participation in power demand response. [0003] The current research on ...
