Demand response client with input data from building 90 at LBNL |
Demand response client with input data from building 90 at LBNL
Information
Model that demonstrates the demand response client,
using as an input for the actual electrical consumption simulated
data from building 90 at LBNL.
Output of the data reader are the outdoor dry-bulb temperature,
the total electrical consumption,
and a signal that indicates whether load shedding is required.
Output of the demand response blocks are the predicted power consumption.
If the input signal shed is true,
then the predicted load is reduced by the amount of power that is shed,
as received from the input signal yShed.
