摘要：
In the trend of large-scale penetration of renewable energy and transformation of traditional power grid to energy Internet, conventional equipment of power grid systems cannot meet the requirements of multi-directional energy flow ability, active control ability of power flow and accurate power supply ability in future power grid. Also, it is difficult to meet the demand of future power market. On this basis, power packetization technology and power packet dispatching system emerge in response top roper time and condition. It can supply power accurately and quantitatively by means of power packetization, and realize active management and regulation of network power flow by using power packet router. This paper summarizes existing research achievements in three aspects, including DC distribution network construction, power supply control, and power packet transmission strategy. Then their problems and shortcomings are analyzed. Based on existing researches, the model structure and future research scheme are put forward. Finally, the difficulties and future directions of related researches are summarized and prospected. © 2019, Power System Technology Press. All right reserved.
