摘　　要：随着城市人口不断增长,能源与环境的矛盾开始制约生态文明的发展,分布式能源是解决这一矛盾的重要方向之一.根据国内外分布式能源的发展趋势,针对我国分布式能源发展所面临的困境,本文提出分布式能源网络系统的基本定义、总体技术架构和主要特征,并分别对各重要组成部分进行了阐述,介绍了分布式能源网络节点的四环节结构设计方法,总结出适用于分布式能源网络系统的协同控制方法.在此基础上,提出了针对分布式能源网络系统的"系统能效理论",并就系统能效理论的三个科学问题进行了阐述,包括结构有序化对系统能效的影响机制,分布式能源网络系统的提质、增量和循环原理,以及基于信息与能量协同的分布式能源网络系统的协同控制原理,指出基于信息与能量耦合的分布式能源网络,是一种具有代表性的新型能源系统发展方向.The exponential growth of urban populations often causes conflict between diminishing energy resources and environmental pollution, hence restricting economic development. As individuals, government agencies and businesses voice their concerns, distributed energy networks promise to provide an essential means to resolve these issues. Within China, the demand for modern distributed energy networks is gaining political and scientific support; however, due to variable end user demands and operating conditions, such energy management systems demand extensive maintenance, require extensive economic investment cost coupled with operational inefficiency. Advanced distributed energy networks are intelligence-based systems developed to integrate multiple power grids and information networks, overcoming current barriers to improve the overall efficiency and economic viability of regional energy infrastructures. Complex distributed energy networks combine advanced energy technologies with micro grids, the internet of things, cloud computing and big data analysis. Fundamentally, the publication describes distributed energy systems from its technical architecture to its primary characteristics while expanding upon its critical components： the four stage design method for energy loops, distributed network nodes, a summary of cooperative control methods and our ＂system efficiency theory＂ for distributed energy networks and its challenges. The first issue involves system infrastructure organization, impacting overall energy efficiency, focusing upon topology influence and stability integration with renewable energy and natural gas units. The second challenge involves quality increments and circulation principles among distributed energy networks, focusing upon active regulation and supply-demand interaction. The final problem is cooperative control principles based upon information and energy integration. The issues involving the four stages energy loop for distributed network nodes was resolved in Hebei Province eco-city
