Abstract: Aiming at the application requirement of the energy router in the energy Internet demonstration projects, this paper proposes one type of chain routing network and an edge diffusion way, thus it can solve the energy management issue in the user’s level in the demonstration projects. Firstly, based on introducing a single energy router, a chain routing network which consists of several energy routers is designed, and completes the regional division for the whole demonstration project. Then the edge diffusion strategy is given, in which a single energy router is regarded as a decision center, which can realize the power balance by passing the power’s imbalance to an adjacent energy router, until the external low-voltage grids. Finally, a communication network and an application scenario are respectively illustrated, so the feasibility of the chain routing network in the demonstration projects can be shown preliminarily.
