Comprehensive Assessment of Integrated Energy Systems Based on an Improved AHP-Gray Assessment Methodology

In the context of the increasing depletion of traditional energy sources and environmental problems, it is imperative to establish a sound energy system and solve new energy consumption problems. This will facilitate energy transformation and promote the green and low-carbon development of the energy industry. To ensure that the integrated energy system can operate economically and efficiently, it is crucial to establish a complete and accurate evaluation system. Therefore, based on the perspective of integrated energy system, this paper focuses on the problems of imperfection and inaccuracy of the evaluation system, and constructs a relatively comprehensive evaluation system for integrated energy system, including relevant indicators such as technical benefits, energy use benefits, environmental benefits, economic benefits and social benefits. In addition, this paper proposes a scientific evaluation method based on the improved AHP-grey evaluation method, which provides a comprehensive evaluation system for the integrated energy system.
