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.

Key words： Cyber-physical systems(CPS) network transmission scheduling variable sampling period energy internet
