Heat Pump Model• The dynamics of a direct air heating system can be sufficiently

described by three thermal masses.• The ambient air of the building interior has smaller storage

volume, and defines a faster dynamics of the system.• the larger storage volume of the building envelope, or structure,

describes a slower dynamics of the system

• The DFR technology has been developed to utilize the demandside resources to provide fast reserves needed in the futurerenewable based power system.

• The DFR technology has been tested by offline simulations in theprevious work.

• The real time HIL tests were conducted to verify the effectivenessof the DFR technology.

• The HIL test results show that the DFR technology cansuccessfully arrest the system frequency and illustrate the efficacyof the SmartBox.
