The DC power packet scheduling system achieves on-demand allocation of electrical energy. However, since it is transmitted on a single distribution line, how to save transmission time becomes an important issue. This paper focuses on the analysis of power packets in DC power packet transmission systems, and proposes a concept of super power packets. This combines multiple powers into one super power packet for transmission and distribution. Considering that the load is different for different power demand, on the basis of the super power packet, a concept of an adjustable super power packet is proposed. This can control the power required to be forwarded to the load. In addition, when synthesizing the super power packet, the power distribution heuristic algorithm is designed according to the urgency and the power of the load demand power. Finally, Matlab software is used to simulate the time relationship and power distribution algorithm of the super power packet. The results show that transmission and distribution through the super power packet can save transmission time, and the super power packet under the heuristic algorithm can meet the needs of more users.
