The traffic mapping and delay analysis of GOOSE (Generic Object Oriented Substation Event) traffic in IEC61850 over TSN were studied in [27]. The time-aware shaping (TAS) mechanism of TSN was evaluated in substations compared with traditional Ethernet [28]. However, how to apply TSN to VPP has not been reported so far according to our knowledge. The 3 GPP 5G technology is also promising for applications in VPP. The 5G network provides three typical services: enhanced mobile broadband (eMBB), ultra-reliable and ultra-low-latency communication (URLLC), and massive machine-type communication (mMTC). The research on the distributed energy scheduling method of VPP in 5G communication environments was reported [29]. [PERSON] et al. proposed the application of 5G radio access network (RAN) slicing to assist the VPP in participating in frequency regulation services [30]. However, how to utilize the 5G technology for the transmission performance guarantee of time-critical traffic in VPP communications is still a research problem. The 5G and TSN integrated networks are studied in 3 GPP. The 5G system acts as a TSN bridge to connect TSN networks or TSN end systems. There is some reported research on 5G and TSN integrated network architecture [31; 32], time synchronization [33; 34], coordinated scheduling [35; 36; 37], network redundancy [38], and so on. However, to the best of our knowledge, there is no research on 5G and TSN integrated networks for VPP. This paper presents a three-layer VPP communication architecture with 5G and TSN integrated networks. It proposes a semi-persistent scheduling with reserved bandwidth sharing and pre-emption (SPS-RBSP) for the time-critical traffic of VPP to guarantee bounded latency and reliability. Performance evaluation results show that the proposed SPS-RBSP effectively reduces the end-to-end delay for both time-triggered traffic and event-triggered traffic in VPP compared with the dynamic scheduling method. It improves the resource utilization compared to the static scheduling method when the network load increases. The contributions of this work are as follows:  
1. We presented a three-layer VPP communication architecture with 5G and TSN integrated networks to provide a guaranteed bounded low-latency and reliable communication service. 2. We analyzed the service types and traffic requirements of VPP and performed traffic mapping in 5G and TSN integrated networks to guarantee the consistency of QoS (quality of service). 3. We designed a semi-persistent scheduling with reserved bandwidth sharing and pre-emption (SPS-RBSP) for the time-critical traffic of VPP and verified its advantages through extensive simulation results. The rest of the paper is organized as follows: Section 2 presents the three-layer VPP communication architecture as well as the service types and traffic requirements of the VPP. Section 3 presents the 5G and TSN integrated network architecture for VPP communications. Section 4 explains the semi-persistent scheduling with reserved bandwidth sharing and pre-emption in 5G and TSN integrated networks for VPP. Performance evaluation and simulation results are shown in Section 5. Finally, the paper is concluded in Section 6.
