With increasing penetration of distributed generation, surplus energy at some critical buses in distribution network will extremely challenge the stable operation of conventional power system. Energy routers (ERs) can be placed at the critical buses so as to achieve flexible management of power flow in active distribution network. It will offer more flexibility to realize the interaction between source and load. In this paper, energy routers are mainly catalogued as source-type and load-type, and then a novel distributed source-load interaction strategy for energy router based active distribution network is proposed, which only requires information exchange between neighbor routers. The interaction strategy includes three parts: the strategy for source-type ERs, the strategy for load-type ERs and the cooperation strategy for multiple source-type and load-type ERs. Moreover, a novel calculating method of power loss is proposed to make strategies applicable considering reverse and forward power flow. Finally, the correctness and effectiveness of the proposed strategies are verified by comparison with optimal routing paths derived by the typical centralized Dijkstra algorithm in the case study.
