综合能源系统建模及效益评价体系综述与展望

Review and Prospects of Integrated Energy System Modeling and Benefit Evaluation

构建清洁低碳、安全高效的现代能源体系是能源革命、《能源发展＂十三五＂规划》的共同目标和要求。在此背景下,综合能源系统的理念应运而生,它是电、气、热、冷等各类能源统一规划、统一调度的综合性能源系统。目前,综合能源系统的系统建模是能源领域研究的热点问题,但已有研究大多是围绕某一特定/假定的区域能源系统进行建模,对综合能源系统的典型架构和系统模型尚缺乏统一的定义和梳理,同时对综合能源系统的效益评价体系研究仍处在起步阶段。在已有研究基础上,提出了区域型综合能源系统的典型物理架构,围绕系统中的独立型设备和耦合型设备构建了对应的物理和经济模型,并对当前综合能源系统的效益评价指标体系和评价方法进行了梳理,提出了未来综合能源系统建模及效益评价体系研究领域的研究重点和发展方向,以期为相关研究和项目落地提供参考和借鉴。

Building a clean, low-carbon, safe and efficient modern energy system is a common goal and requirement of energy revolution and the ＂13 th Five-Year Plan for Energy Development＂. Based on this background, the concept of integrated energy system comes into being. Integrated energy system is a comprehensive energy system with unified planning and unified dispatching of electricity, gas, heat, cold and other energy sources. At present, modeling of integrated energy system is a hot issue in the field of energy research. However, most of existing researches model a certain/assumed regional energy system without systematic review and summary of physical and economic models. At the same time, the research on benefit evaluation system of the integrated energy system is still in its infancy. This paper summarizes existing researches in China and abroad, and proposes a typical physical architecture of regional integrated energy system. Corresponding physical and economic models are built around independent devices and coupled devices in the system. In this paper, current benefit evaluation index system and evaluation method of comprehensive energy system are reviewed, and the research focus and development direction of future integrated energy system modeling and benefit evaluation system research is put forward to provide reference for related research and project implementation.
