In response to the issues of large-scale growth in distributed energy resources and new types of loads in rural areas, coupled with the lack of coordinated management and control for source-grid-load-storage, this study examines typical energy consumption scenarios covering all voltage levels in rural areas. On this basis, a rural energy internet system architecture featuring the “integration of wind-solar-vehicle-storage-charging” is designed. The paper describes the main networking modes and control technologies of this system in multi-element scenarios of rural microgrids, and analyzes the application and demonstration cases of this technology in a full-scale test base. This full-scale test system possesses a series of test functions, including grid-connected performance testing of multiple new-type elements, aggregation of resources from various entities and flexible networking, multi-energy conversion and autonomous operation of micro-energy grids, and collaborative interaction between micro-energy grid clusters and the upper-level power grid.
