The VPP integrates various distributed energy resources (DERs), such as distributed power generation, energy storage, controllable loads, and electric vehicles, to incorporate them into the grid as a single administrator [6; 7]. It provides the power auxiliary service with numerous advantages and incentives for customers, prosumers, and operators [8]. The VPP is implemented based on a software and network for sending and optimizing the distributed energy resources remotely and automatically [9]. The VPP consists of a group of dispersed generator units, loads, and storage systems. It operates as a single power plant. The VPP control center platform coordinates the power flow, load, and generator storage. The VPP consists of three component technologies [1]. They are generation technology, storage technology, and information and communication technology (ICT). The generation technology consists of stochastic natural energy sources (e.g., wind, water, and sunlight) and traditional dispatchable power plants and energy storage. The energy storage technology balances the energy production and supply according to the electricity demand change. The information and communication infrastructure connects the components of VPP and it enables efficient communication among them for the smooth and reliable operation of the VPP. The current VPP communication technologies include Ethernet and LTE (long-term evolution) [10; 11; 12]. Ethernet and LTE are utilized for wireline and wireless communications between local DER systems and the remote VPP control platform. The dynamic operation of VPP requires low latency and a reliable communication service. For example, the fast frequency regulation dispatchable commands from the VPP control platform are expected to arrive at local DER system within tens of milliseconds without loss [11]. However, Ethernet frames may get lost due to network congestion and the delivery delay of Ethernet frames cannot be guaranteed [13]. The LTE technology provides flexible wireless access service but it lacks the capability for bounded low delay and a reliable communication service for critical traffic [14]. A hybrid wired and wireless deterministic network based on time-triggered Ethernet (TTE) and 5G for smart grids was proposed in [15]. However, the TTE protocols are private and the compatibility remains a problem to be solved. [PERSON] et al. studied the device access optimization problem in heterogeneous networks of VPP considering the packet loss constraint [16], and this paper focuses on resource scheduling to guarantee packet delay. A decentralized IoT architecture of DER in VPP based on information pipe technology and cloud/fog computing was proposed in [17]. However, it is only for applications in DER management systems. The challenge in current network solutions for VPP is the packet delivery latency guarantee for critical delay-sensitive messages. Time-sensitive networking (TSN) is a set of standards defined in the IEEE 802.1 working group to enhance the capabilities of Ethernet technology [18]. TSN has four enhancements compared with traditional Ethernet. The first part is traffic shaping and scheduling for the performance guarantee of bounded latency [19]. The second part is frame replication and elimination for reliability (FRER) [20; 21]. The third part is high-precision time synchronization based on the generalized precision time protocol (gPTP) [22]. The fourth part is flexible network management and configuration based on the stream reservation protocol (SRP), centralized network configuration (CNC), and YANG (Yet Another Next Generation) data model [23]. The TSN is promising for applications in industrial automation systems, smart grids, in-vehicle communication networks, and so on. It guarantees the transmission performance of the critical traffic while providing a converged transport platform for other types of traffic at the same time. TSN technology and its application in energy internet were presented in [24]. Research on TSN tests for smart substations was reported in [25; 26].
