摘　　要：随着人类社会的不断进步和发展,人们对能源品质和数量的需求日益提高.长期以来,在中国能源结构中,以煤和石油为代表的化石能源占比过高,导致区域环境问题不断恶化,可再生能源利用与分布式能源普及应用是解决这一问题的重要手段之一.通过对国外分布式能源和微网的发展趋势,以及对国内分布式能源发展现状和面临的困境进行分析,提出基于可再生能源和天然气融合的分布式能源网络将成为分布式能源的重要发展方向之一.本文给出分布式能源网络的定义和特征,并以中德生态园和河北廊坊分布式能源网络为例,介绍两个典型的分布式能源网络项目,包括物理网络结构、系统结构和实施方法与效果.最后提出分布式能源网络系统的未来发展方向将是能源互联网,并总结出以能源互联网为代表的未来能源体系的基本特征.China＇s energy infrastructure is predominantly fossil fuel based such as coal and petroleum, resulting in the deterioration of surrounding environments. The application of renewable resources, natural gas suppliers and distributed energy systems are a critical component in alleviating the present detrimental situation; by analyzing successful distributed power and micro grid systems internationally and applying it to domestic networks, these systems can be customized and calibrated to maximize efficiency. Furthermore, the demographics of distributed energy users is expanding from exclusive industrial consumers to commercial and residential customers, increasing demand for modular units, attracting the attention of the Chinese central government＇s environmental policymakers. Within China, the implementation of distributed energy networks has been limited to industrial parks, economic and technological development zones. In this article, the characteristics of distributed energy networks is defined utilizing case studies involving the Sino German Eco-Park and Langfang City, introducing the mainstream energy networks including infrastructures, system hierarchy, its implementation methods and overall effects. In the Sino German Eco-Park, a distributed energy network is combined with a centralized system composed of one regional and six energy substations, providing electricity for blocks one through eight whose energy scheduling mode being divided into two inter-network and intra-network scheduling. Using the energy operations center, electrical transmission across the blocks is achieved via energy allocation between micro grids combined with the installation of natural gas, renewables and smart power grids; this enables the Sino German Eco-Park technical index to accomplish higher power distribution levels of efficiency. In Langfang City, the first city-level reconstruction and distributed energy project in China, the micro grid at New Chaoyang block is described in detail. Finally, the future of distributed ene
