Benefit Assessment of Integrated Energy Systems Considering Hydrogen Utilization in the Context of Dual Carbon Goals

In traditional comprehensive energy system benefit assessment studies, it is common to rely on a single weighting method, considering only subjective or objective weights to determine the importance of assessment indicators. This approach often fails to adequately combine subjective and objective factors. To integrate the advantages of both methods, this paper proposes a comprehensive evaluation model that combines the Best-Worst Method (BWN) and an improved entropy method with the coefficient of variation. The model adds a hydrogen production process to the common integrated energy systems for self-use or external sale of hydrogen. By selecting the scenario of a green hydrogen industrial park project, the newly constructed comprehensive evaluation model is applied for benefit assessment and case analysis. Through case verification, this study’s method has been confirmed to be scientific and effective.
