Abstract

The invention relates to a water supply temperature regulation and control method based on target energy consumption management and control, which is used for calibrating model parameters according to historical data of a heat supply network in combination with a specific scene, and carrying out periodic calibration and dynamic correction in an operation process. According to the water supply temperature regulation and control method based on target energy consumption management and control, the water supply temperature is determined based on the target load and the flow constraint of an actual system, the self-learning, self-adaption and self-optimization-approaching capabilities are achieved, and target energy consumption accurate management and control of on-demand heat supply under the dual-carbon target background can be achieved.

Description

technical field [0001] The invention belongs to the technical field of central heating, relates to the operation adjustment of a central heating system, and in particular to a water supply temperature control method based on target energy consumption control. Background technique [0002] Central heating is the most common form of heating in northern my country. "Heating on demand" is the basic path to ensure users' heat demand while achieving significant energy saving and emission reduction. Due to the large thermal inertia of the system, the thermal inertia of the building, and the time-varying nature of the user's heat consumption mode in central heating, the transient adjustment response capability of the system is limited, and there are different degrees of mismatch between supply and demand and energy waste in the actual heating process. . [0003] In recent years, with the application of Internet of Things technology and the development of automatic control tech...
