A LargeScale Testbed
as a Virtual
Power Grid
For Closed-Loop Controls
in Research and Testing

By Fangxing Li, Kevin Tomsovic,
and Hantao Cui

T

THE ELECTRIC POWER GRID IS UNDERGOING
unprecedented modernization toward higher reliability,
higher efficiency, and lower cost through the integration of
renewable energy, wide-area monitoring, and advanced control technology. This integration is making the transmission
grid overwhelmingly complex to understand and model to
apply new control or actuation technologies. This calls for
a fast-prototyping platform for research and testing under
the new transmission technology paradigm. Such a platDigital Object Identifier 10.1109/MPE.2019.2959054

form should be highly integrated, closed loop, and capable
of mimicking a real power grid for testing new controls or
algorithms. However, traditional software simulation packages usually perform specific tasks such as dynamic simulation or state estimation but lack the capability of providing
an integrated closed-loop platform.
In other words, power system researchers often struggle to
obtain realistic data for research under the new transmission
paradigm since they do not own or operate a real power grid.
Typically, a researcher in a power system control study will
employ a few tools and manually create interactions among
simulation programs and scripts to achieve various goals.
