With the development of global warming, environmental degradation and energy crisis, a new round of energy revolution has been set off all over the world. District energy internet comes into being with this opportunity, which aims to promote the consumption of renewable energy, and improve the efficiency of multi-energy utilization. In this paper, a typical district classification method based on TOPSIS model was proposed, which divided districts into six types. According to the characteristics of different types of districts, implementation routes of Energy Internet development were planned. Last but not least, case studies of several district energy internet were analyzed as well.
