摘要：
Taking the regional integrated energy system as the research object，the study firstly conducts an optimization strategy analysis. Then，a multi-objective optimization is carried out，specifically targeting energy efficiency，economy，and environment. Subsequently，using an improved BWM method（HWBM）combined with the entropy weight method，an objective-subjective weight evaluation system is established，leading to the determination of an optimal system configuration and operational planning. Findings reveal that the design strategy effectively addresses the multi-energy coordination issue. Compared to the traditional combined cooling，heating，and power system，the optimal system achieves a 14.9% reduction in fossil fuel consumption，8.9% in annual investment costs，4.7% in energy costs per degree，14.9% in carbon emissions，and 18.1% in water consumption. The outcomes emphasize the notable advantages in energy，economy，and environmental protection. © 2024 Science Press. All rights reserved.
