In this study, we develop a hardware-in-the-Loop (HIL) simulation platform for the investigation of Vehicle - Grid Integration (VGI) at campus-level distribution network. The VGI HIL simulation is performed with a real-time simulator, OPAL-RT. The VGI HIL model can communicate with a Smart Energy Plaza at Argonne National Laboratory through Message Queuing Telemetry Transport (MQTT) communication protocol. A hierarchical energy management system is also developed, which manages VGI operation at both campus-level and node-level. At the distribution network level, it distributes available power to individual nodes. At the node-level, it coordinates PEV charging load and non-PEV load to track the assigned power reference, meanwhile, fairly dispatches the limited power to PEVs within the node. To validate the developed VGI model and evaluate the effectiveness of the hierarchical energy management algorithms, HIL simulations are performed with different power limits. The generated simulation results are further analyzed and compared.
