摘　　要：分布式供能系统为直接面向用户的可持续发展能源动力系统,对开拓能源利用新模式、推动可再生能源发展应用、优化能源结构以及系统节能等将发挥重要作用。文章基于作者团队有关的研究成果和国内外相关的研究情况,综述分布式供能系统:概述了新系统概念、技术特点与梯级利用节能理念及国内外研究发展简况;全面归纳新系统集成的主要关键技术(系统集成技术和主要过程部件关键技术);凝练归纳新系统开拓集成的主要核心科学问题(系统设计优化和评估基础问题,多能源互补的多功能梯级综合利用机理,不同循环的耦合机理以及变工况主动调控机制和优化基础等)。Distributed energy systems （DES）, which are typically composed of a number of modular and small scale technologies and situated close to the end users, can be regarded as an essential complement to conventional centralized power network. They make contributions for renewable energy promotion, energy conservation, energy structure optimization and emission reduction. Based on the research achievement of authors＇ group, this paper has summarized the system concept and development status; technological features, key technologies associated with both system integration and key processes; key scientific issues including system performance evaluation, mechanism of muhiple energy comptementation and their cascade conversion, off-design operation strategies.
