Abstract:

In order to make full use of the growing renewable energy and promote energy structure reform， energy internet is considered as an effective way to promote the reform because it can make full use of energy and increase the permeability of renewable energy. The technical characteristics and connotation of energy internet has been elaborated. Important parts of the energy internet which are energy interconnected microgrid, its three layer architecture and key devices on each layer of structure. The connection between photovoltaic, wind energy storage microgrid and active distribution network is put forwards. The architecture of software and hardware applied to a campus energy internet has been achieved, which demonstrates the validity of the structure of energy internet microgrid.

Key words:

energy internet, microgrid,  renewable energy, three layer architecture
