| 摘要: |
| 直流电力分组调度系统实现了电能的按需分配。然而，由于是在单个配电线上传输，如何节省传输时间成为一个重要问题。着重对直流电力分组传输系统中的电力包结构进行了分析，提出一种超级电力包的概念，将多个电力包合为一个超级电力包进行输配电。考虑到负载对于电力需求的多少是不相同的，在超级电力包的基础上，又提出一种可调节超级电力包的概念，能够控制转发给负载各自需要的电力。另外，在合成超级电力包时，根据负载需求电力的急迫性和数量设计了电力分配启发式算法。最后，使用Matlab软件对超级电力包的时间关系式和电力分配算法进行了仿真分析。结果表明，通过超级电力包进行输配电能够节省传输时间，另外，按启发式算法合成的超级电力包能够满足更多用户的需求。 |

| Abstract: |
| 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.
