Active distribution network （ ADN） is the power distribution system which can actively control and manage distributed energy; it is an effective way to solve the problem of high proportion of distributed clean energy in power system and energy internet. The definition and basic characteristics of ADN are introduced, and the practical significance of the ADN orienting to energy internet is summarized. Some key technologies of AND are presented, including integrated planning, demand response and distributed cooperative dispatch, etc. Also some technical support of ADN are introduced, such as AC and DC active distribution network, energy storage technology, information and communication technologies, electric vehicles and vehicle - to - grid （V2G）. ADN is one of the effective approaches to admit large scale distributed energy resource （DER） into grid. With the developing of technologies, ADN will transit to the core of smart distribution network orienting to energy internet, and accelerate to cooperate with energy internet,and it has a wide range of application areas and considerable application value.
