[0002] In today's energy-saving and environmentally conscious world, the efficient operation and energy use of thermal systems have become crucial aspects in both industrial production and everyday life. Conventional, pre-optimized control methods for thermal systems lack adaptability, real-time performance, accuracy, and energy efficiency optimization. Therefore, they cannot meet today's energy efficiency and environmental protection requirements. The introduction of optimized control methods can address these shortcomings and improve the energy efficiency and operational efficiency of the system.
[0003] Conventional control methods for thermal systems typically employ static control strategies that often struggle to adapt to changing system operating conditions. This can result in the system not fully utilizing current operating conditions, leading to energy waste and reduced system efficiency. Furthermore, conventional methods often lack real-time optimization capabilities, preventing them from monitoring and adjusting the system's operating state in real time. Consequently, the system cannot respond promptly to changing environmental conditions, resulting in reduced energy efficiency and resource waste. Additionally, conventional control methods often rely on engineers' experience and rules, without requiring thorough analysis and utilization of extensive historical data.This can lead to the system's control strategies being inaccurate and inefficient, and unable to adapt to the control of multiple interacting parameters and constraints.

[0020] This step allows for a comparison of real-time energy efficiency data and energy efficiency forecast data in the frequency domain to determine their similarity. This contributes to a more comprehensive understanding of the relationship between the two signals and provides support for further analysis and decision-making.
[0021] In one embodiment of the present application, a method for optimizing and controlling thermal systems is provided, which involves evaluating and calculating the energy efficiency difference of the thermal system based on the results of the comparative analysis in order to obtain an energy efficiency difference rating of the thermal system; determining the similarity between the real-time energy efficiency data and the energy efficiency forecast data, as well as a first average value and a first number of curve segments of the first category and a second average value and a second number of curve segments of the second category; evaluating and calculating, respectively, the first average value of the curve segment of the first category and the second average value of the curve segment of the second category to determine a first difference rating and a second difference rating.Calculating the assessment value of the energy efficiency difference of the thermal system based on the similarity between the real-time energy efficiency data and the energy efficiency forecast data, the first difference assessment value and the first number of curve segments of the first category, and the second difference assessment value and the second number of curve segments of the second category; The formula for calculating the assessment value of the energy efficiency difference of the thermal system is:; L=S×(g1×Xm+g2×Yn), where L is the energy efficiency difference rating of the thermal system, S is the similarity between the real-time energy efficiency data and the energy efficiency forecast data, g1 is the preset weighting of the curve segment of the first category, X is the first difference rating of the curve segment of the first category, m is the first number of curve segments of the first category, g2 is the preset weighting of the curve segment of the second category, Y is the second difference rating of the curve segment of the second category, and n is the second number of curve segments of the second category.
[0022] Specifically, the first average value of the curve segment of the first category and the second average value of the curve segment of the second category are evaluated to obtain the first difference assessment value and the second difference assessment value;
[0023] The similarity between the real-time energy efficiency data and the energy efficiency forecast data is used as S; the preset weight of the curve segment of the first category is used as g1, the first difference score of the curve segment of the first category is used as X, and the first number of curve segments of the first category is used as m. The preset weight of the curve segment of the second category is used as g2, the second difference score of the curve segment of the second category is used as Y, and the second number of curve segments of the second category is used as n; the energy efficiency difference score L of the thermal system is calculated.In this step, the similarities between the real-time energy efficiency data and the energy efficiency forecast data, as well as the difference rating and the number of curve segments in the first category and the second category, are comprehensively considered to determine the energy efficiency difference rating of the thermal system.

[0025] Specifically, the energy efficiency difference rating is divided into different intervals, for each of which corresponding optimization coefficients are preset. These optimization coefficients can be proportional coefficients used to adjust the system parameters, allowing different optimization measures to be taken based on the different energy efficiency difference ratings. During system operation, the real-time energy efficiency difference rating is determined and compared with the corresponding relationship between the predefined optimization coefficient and energy efficiency difference rating interval to determine the associated interval.Select the optimization coefficient that corresponds to the energy efficiency difference rating interval based on a mapping relationship of the interval to which the energy efficiency difference rating belongs within the corresponding relationship of the optimization coefficient-energy efficiency difference rating interval. Based on the selected optimization coefficient, real-time characteristic parameters are adjusted. These real-time characteristic parameters can be control parameters in the system, such as temperature and flow rate, etc. The adjusted real-time characteristic parameters can be used to control the operation of the thermal system to achieve energy efficiency optimization. This step enables the selection of appropriate optimization coefficients based on the real-time energy efficiency difference rating and the corresponding adjustment of the real-time characteristic parameters to control the operation of the thermal system.This real-time adaptation and optimization method can help the system to better adapt to the operating requirements of different energy efficiency conditions and improve the system's energy efficiency performance.
