Description

Technical Field

[0001] This invention relates to the field of coupled system evaluation and energy system analysis technology, and in particular to a method and equipment for evaluating the coupling coordination degree of an integrated energy system in an industrial park. Background Technology

[0002] Industrial parks, as concentrated areas of energy consumption and carbon emissions, are transforming their energy systems into highly intelligent integrated energy systems (IES) that integrate multiple energy forms. IES, by integrating renewable energy, energy storage, and combined cooling, heating, and power technologies, form a complex system with a high degree of integration of "source-grid-load-storage." A scientific and comprehensive evaluation of its planning and design scheme is a key prerequisite for ensuring its technical and economic viability and environmental friendliness.

[0003] Existing IES evaluation methods have the following key shortcomings:

[0004] First, the evaluation dimensions are singular, lacking consideration of system coupling: Traditional evaluation methods often focus on a single dimension, such as only evaluating economic or technical aspects, while ignoring the IES as a whole, where there are profound coupling and interaction relationships between its internal physical energy network, information and communication network, and market transaction mechanisms. This fragmented evaluation approach cannot reveal the synergistic effects or constraints between the various subsystems of the system, leading to one-sided evaluation results and potentially guiding planning decisions that are "locally optimal but overall suboptimal."

[0005] Second, the methods for assigning indicator weights have inherent flaws: Indicator weight allocation is a core element of multi-criteria decision-making evaluation, and its rationality directly affects the accuracy of the evaluation results. Subjective weighting methods, such as the analytic hierarchy process (AHP), heavily rely on expert experience. When there are numerous evaluation indicators, this not only increases the cognitive burden on experts but also easily leads to distorted weighting results due to subjective judgment biases and logical inconsistencies. Objective weighting methods, such as the traditional entropy weighting method, rely entirely on the distribution characteristics of the original data to determine the weights. While avoiding subjective arbitrariness, they completely ignore the valuable experience of experts in specific fields, potentially leading to calculated weights that contradict the actual engineering situation. Simple combined weighting methods, such as arithmetic averaging of subjective and objective weights, lack a solid theoretical foundation to scientifically balance the conflict and complementarity of the two types of information. The combination method is relatively arbitrary and cannot guarantee the scientific validity and robustness of the final weights.

[0006] Therefore, there is an urgent need for a comprehensive evaluation method for the integrated energy system of industrial parks that can fully consider the multi-layered coupling characteristics of physical architecture, information communication, and market transactions, and adopt a scientific and rigorous combined weighting mechanism, in order to address the shortcomings of existing technologies. Summary of the Invention
