Internet technology and new energy technology are driving the energy revolution

and the new generation of green and highly-efficient energy utilization system merging smart grid and energy-net is now emerging. Against this background

three different prospective modes of the merger of smart grid with energy-net i. e. Smart Grid 2. 0

Interconnected Energy Network and Internet+ Energy Network are dealt with. Then

from the perspective of morphological characteristics

constraining conditions and application scenarios

three different merging modes are further discussed. Finally

it is concluded that different merging modes of smart grid with energy-net in different periods of time or different regions are the typical forms of development. And the distribution pattern is constrained by the development of related technology

the energy resources and macro-oriented policies. This work is supported by the Major Consulting Program of Chinese Academy of Engineering (No. 2015-ZD-09-09).
