与电力系统协同区域型分布式冷热电联供能源系统集成方案

在分析了分布式冷热电联供系统(DES/CCHP)的研究和发展面临的新机遇的基础上,提出了与电力系统协同的区域型DES/CCHP的总体集成思路和技术集成方案。通过变结构的集成方式来实现系统结构与功能的协同优化,提出了多个区域型DES/CCHP、区域内其他形式的分布式能源系统、多源链式微网、多源环状热网和大电网的整合集成技术,并通过能源利用流程的动态组合,提出了协同互补运行方式。为清洁能源的高效、梯阶、互补利用及分布式可再生能源的规模化应用提供一种通用的集成方案。该集成方案将在湖南省创建国家示范性工程中得到应用。

An Integration Scheme for DES/CCHP Coordinated with Power System

Based on an analysis of research and development of the distributed energy system and combined cold, heat and power generation system (DES/CCHP), this paper presents an overall integration thought and technological integration scheme for regional DES/CCHP coordinated with the power system. With the coordinated optimization of structure and function based on the integration modes of variable structures, this paper presents the integration technology scheme on several regional DES/CCHP, the multi-source energy network system and the distributed renewable energy system. In the meantime, the collaborative and supplementary operation mode is employed on the basis of the dynamic composition of the energy utilization process to provide a common integration scheme for efficient, cascade use of clean energy and large-scale application of distributed renewable energy. The integration scheme is expected to be applied in a national demonstration project in Hunan Province.
