Abstract :
The introduction of communication systems to power system controllers have brought in another layer of complexity in their design and operation. In this paper a Plug-in Hybrid Electric Vehicle (PHEV) charging facility is studied. A linearized model of the facility is built including both the dc/dc and dc/ac converters of the Distributed Energy Resources (DER). In addition, a control strategy that includes both local and networked loops is proposed to monitor and control the dc bus voltage of a Local Energy Storage (LES) unit. This dc bus voltage is crucial to the self-sustaining capabilities of the system. Impacts of different communication factors to the system stability are analyzed. Lastly, the small signal model, control strategy, and stability analysis are verified with real time simulations.
