Demand side response control method based on temperature control load electric water heater and system thereof

Abstract

The invention provides a demand side response control method based on a temperature control load electric water heater and a system thereof. Electric water heater equipment is molded to form an electric water heater polymerization load demand model; a water use amount of the electric water heater is considered, and an upper temperature limit, a lower temperature limit and a switch state of the electric water heater are reasonably controlled, so that a dynamic process and electric energy consumption of the electric water heater can be changed; various relevant factors such as an electric water heater parameter, an external factor and a communication process which affect response of the electric water heater are calculated so as to form a control framework for controlling the electric water heater, so that the electric water heater can effectively participate in a DR (data recorder); therefore, service is provided for a power grid, the application reliability of the electric water heater participating in the DR is improved, the relevant factors can be adjusted, and the application effect of the electric water heater to the field of the DR can be enhanced; resources are saved, and the electric energy quality can be improved.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a demand-side response control method based on temperature-controlled load electric water heaters, and a demand-side response control system based on temperature-controlled load electric water heaters. Background technique [0002] With the introduction and development of the concept of smart grid, Demand Side Management (DSM) has gradually become a research hotspot in the power industry. It uses advanced measurement communication technology and effective control methods to make load a responsive scheduling resource. [0003] Demand response (Demand Response, DR) is an important means of DSM, it refers to when the electricity wholesale market price rises or the system reliability is threatened, the power user receives the direct compensation notice or the power After the price rise signal, change its inherent customary power consumption mode, to reduce or shift the power cons...

Problems solved by technology

[0006] Aiming at the problem that the existing electric water heaters cannot participate in the response control process of the power demand side, resulting in insufficient demand-side response, the present invention provides a demand-side response control method and system based on temperature-controlled load electric water heaters. The modeling of electric water heaters and the synthesis of various related factors such as electric water heater parameters and external factors that affect the response of electric water heaters enable the response control process on the power demand side to incorporate the influence of electric water heaters and improve the accuracy of response control on the power demand side
