以区域综合能源系统为研究对象,首先开展能源系统的优化策略分析工作,然后针对能效、经济、环境进行多目标优化求解,最后引入犹豫评价,建立并应用改进最优最劣法（HBWM）-熵权法的主客观权重评价体系,得到最优系统配置和运行规划。结果表明：优化设计策略有效解决了多能协同问题;相较于传统冷热电联供系统,最优系统减少14.9%化石燃料消耗、8.9%年投资成本、4.7%度能成本、14.9%碳排放量和18.1%用水消耗,在能源、经济、环保3个方面有明显优势。
Abstract
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.
