摘　　要：随着园区综合能源系统(integrated energy system,IES)对系统状态感知、调控水平要求不断提高,关键信息在通信网络中的高效传输成为综合能源系统状态快速感知、快速调控的关键。首先提出基于物联网的园区综合能源系统信息采集、传输、控制体系,结合综合能源系统物理3层架构建立基于物联网的园区综合能源系统3层星型通信网络模型。在该模型中通过基于端口的虚拟局域网(virtual local area network,VLAN)划分实现综合能源系统通信网络的低延时、高吞吐性能。在VLAN划分的基础上,设置链路利用率、业务应答时间阈值,探究了通信网络在所设条件下的临界运行状态,为综合能源系统快速通信网络规模设置提供了定量分析依据。仿真验证了所提方案的可行性。With the increasing demands of park integrated energy system(IES)for system state perception and regulation level,the efficient transmission of key information in the communication network has become the key to the rapid perception and regulation of the IES state.Firstly,this paper proposes an information collection,transmission,and control system for the park IES based on the Internet of Things(IoT).Combined with the physical three-layer architecture of the IES,an IoT-based park IES three-layer star communication network model is established,in which the low-latency and high-throughput performance of the IES communication network is achieved through port-based virtual local area network(VLAN)division.On the basis of VLAN division,the link utilization rate and service response time threshold are set and the critical operating states of the communication network are explored under the set conditions,which can provide a quantitative analysis basis for the setting of the IES fast communication network scale.Simulation results have verified the feasibility of the proposed scheme.
