Query: Microgrid Control Using Remote Controller Hardware-in-the-Loop Over the
  Internet   A centralized microgrid power management and control system is developed and
tested with a Hardware-In-the-Loop (HIL) Real-Time Digital Simulator (RTDS)
model of an existing microgrid that communicates in real-time with the
controller over the Internet. The controller leverages Phasor Measurement Units
(PMUs) for measuring power flow and adjusting inverter power references in
real-time. The control objectives are power and State-of-Charge (SoC) control,
subject to inverter power amplitude and rate limits and communication
constraints. The controller incorporates units of power control, SoC control,
and adaptive reference scheduling to achieve seamless microgrid operation.
Real-time, over the internet, hardware-in-the-loop tests between the controller
and the simulator are realized and indicate stability and performance of the
microgrid control system.
