摘要 信息物理融合系统(CPS)是实现能源互联网中信息技术和电网技术融合的重要技术体系。针对在CPS中采用传统调度策略导致的高丢包率、低利用率和网络延时长等问题,提出了一种多重优先级的调度策略,该调度策略能够保证信息在网络中传递的灵活性;基于该调度策略,针对CPS不同组成部分的特点,提出了两种变采样周期算法,该算法能够同时兼顾网络资源情况和系统控制性能,使系统在网络资源受限的情况下能够达到稳定状态。最后,根据能源互联网的特点,描述了如何将该调度策略应用于能源互联网中。

Abstract:Cyber-physical systems(CPS)is a key technology system for combining information technology and power grid technology in energy internet.Aiming at the high packet loss rate,low utilization ratio and the network delay problems caused by the traditional scheduling strategy in CPS network,a multiple priority scheduling strategy is proposed,this scheduling strategy can guarantee the flexibility of information transmission in the network.Based on this scheduling strategy,according to the characteristics of different components of a CPS,two variable-period sampling algorithms are proposed.These algorithms can balance network resource situation and system control performance,promote a CPS with limited network resource to reach steady state as soon as possible.Finally,according to the characteristics of energy internet,this paper shows how to apply the variable sampling period-based CPS multiple priority network transmission scheduling to energy internet.
