本文研究并提出了笔者课题组提出的电力分组调度系统有别于传统配电系统的一个优势功能。重点介绍电力分组调度的安全特性，主要包括信息安全（保护分组信息不受攻击者攻击）和电力安全（保证分组供电负载安全）两个方面。为了实现信息安全和电力安全，我们在发送电力包之前引入了简单的调制。特别是为了保护数据包的信息，首先提出了部分数据包调制，即调制数据包的部分信息标签。基于混沌信号的调制方案是实现这一目标的一种可能，本文采用差分混沌移位键控（DCSK）方案。接下来，可以通过对数据包的有效负载应用脉宽调制（PWM）来实现电源安全性。同时，考虑到噪声对分组调度的影响，提出了利用DCSK方案对有效载荷进行进一步调制，使噪声的频谱得到扩展。因此，我们引入了全包调制的概念，其中PWM首先应用于数据包的有效载荷，然后使用DCSK方案在整个数据包中应用调制。这样既能保证信息安全和电力安全，又能扩大噪声的频谱。另外，值得一提的是，严格审查调制方法并不是目前的目标。
This paper investigates and proposes one advantageous function of a power packet dispatching system, which has been proposed by authors’ group with being apart from the conventional power distribution system. Here is focused on the feature on safety of power packet dispatching which covers two aspects: information safety (protect the information of packet from attackers) and power safety (keep loads safe regarding supplied power from packet). For the purpose of achieving the information safety and the power safety, we introduce simple modulations of power packets before sending them. In particular, in order to protect the information of packets, partial packet modulation is proposed first, i.e., modulating partial information tags of packets. Modulation scheme based on chaotic signal is one possibility for this purpose and we adopt the differential chaos shift keying (DCSK) scheme in this paper. Next, the power safety can be achieved by applying pulse width modulation (PWM) to the payload of packets. Meanwhile, considering the effect of the noise on the packet dispatching, further modulation of the payload using the DCSK scheme is proposed, which can spread the spectrum of the noise. Consequently, we introduce the concept of whole packet modulation, in which PWM is applied to the payload of packets first, and then modulation using the DCSK scheme is applied throughout the whole packet. In this manner, both the information safety and the power safety can be achieved and the spectrum of noise is spread as well. Additionally, it is worth mentioning that the rigorous examination of the modulation method is not the target in this moment.
