An energy internet and energy routers

The increasing energy demand seriously challenged the current energy system, carbon emission limitation required to change traditional energy production forms, therefore renewable and green energy resources shall play the most important role for the coming energy supply system. The development and mature of electric transmission and storage, information communication and high performance computing have provided solid foundation of efficiently applying distributed and intermittent renewable resources. For the imagination of energy internet, we study an energy routers based scheme to construct an energy internet. Moreover, we discuss comprehensively all kinds of key technologies including the object of designing energy routers, possible deployment schemes and existing related techniques. In the end, we point several research aspects which need urgently to make breakthrough based on our current results.
