摘　　要：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。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.
