Due to the uncertainties introduced with this high penetration, better monitoring and control of the assets becomes crucial for the system stability. Multiple standards are available to enable interoperability in PV inverters. In this paper, an interoperable controller, enabled by DNP3 communications protocols, is developed for a grid-connected, three-phase PV inverter. Advanced inverter control function setpoints like VVAR curves, ride-through curves are sent from a data management system application to the PV inverter through DNP3. The DNP3 server for the PV inverter is programmed on the real-time layer of the inverter controller. A controller hardware-in-the-loop experimental setup is used to validate the developed communications capability of the PV inverter. This work will enable grid integration of smart PV inverters with advanced grid-support functions as well as allow better monitoring and control of assets for grid stability.
