【摘要】 随着新型城镇化的加速，城市普遍出现空间布局紧凑化、功能集中化的发展模式。大力推动低碳综合能源系统高效应用成为了建筑节能低碳运行的关键举措。虽然目前综合能源系统在国内外应用较多，但供需精准匹配一直是其高效应用的瓶颈。本项目以提升综合能源系统能效和规模化应用效果为目标，针对需求侧用能和供应侧供能的全要素，围绕“需求侧负荷特征及用能机理-综合能源系统多目标优化设计-综合能源系统协同精准调控”全过程，构建了基于供需精准匹配的综合能源系统优化关键技术体系，实现系统投资节约15%-20%，设计成本降低50%以上，系统运行节能量为17%-30%，集成可再生能源的系统节能量达到40%以上，并进行了大规模工程应用，对推进建筑领域运行节能减排起到了重要支撑作用。更多还原

【Abstract】 With the acceleration of new urbanization, cities generally appear to have compact spatial layouts and centralized development patterns.Vigorously promoting low-carbon integrated energy systems has become a key initiative for building energy-saving and low-carbon operation. Although such systems are widely used worldwide, the precise matching of supply and demand remains a bottleneck in its efficient application. Aiming at improving the energy efficiency and scale application effect of the comprehensive energy system, this project focuses on the full elements of demand side energy consumption and supply side energy supply, revolves around the entire process of "demand side load characteristics and energy consumption mechanisms-multi-objective optimization design of the comprehensive energy system-collaborative and precise regulation of the comprehensive energy system", and constructs a key technology framework for integrated energy system optimization based on precise matching of supply and demand, achieving system investment savings of 15%-20%, design cost reduction of over 50%, operation energy savings of 17%-30% and energy savings in integrated renewable energy systems of more than 40%. The large-scale engineering applications have played an important supporting role in promoting energy conservation and emission reduction in the building field.更多还原
