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 energy network system is the energy internet as summarized an ecological, diversified and multilateral commodity whose logistics are intelligent and standardized.
