  This paper is the second part of a two-part series presenting the results
from an experimental demonstration of frequency regulation in a commercial
building test facility. In Part I, we developed relevant building models and
designed a hierarchical controller for reserve scheduling, building climate
control and frequency regulation.
  In Part II, we introduce the communication architecture and experiment
settings, and present extensive experimental results under frequency
regulation. More specifically, we compute the day-ahead reserve capacity of the
test facility under different assumptions and conditions. Furthermore, we
demonstrate the ability of model predictive control to satisfy comfort
constraints under frequency regulation, and show that fan speed control can
track the fast-moving RegD signal of the Pennsylvania, Jersey, and Maryland
Power Market (PJM) very accurately. In addition, we report the observed effects
of frequency regulation on building control and provide suggestions for
realworld implementation projects. Our results show that hierarchical control
is appropriate for frequency regulation from commercial buildings.
