This presentation introduces the hardware-in-the-loop (HIL) test of demand as frequency controlled reserve (DFR). The DFR control logics have been implemented in the SmartBox. The HIL was conducted by having the SmartBox connected to the real time simulations and the performance of the SmartBox was tested with difference frequency events in the simulated power systems. The HIL test results show that the implemented DFR in the SmartBox can efficiently arrest the system frequency during frequency events and help recover the system frequency.
