Hardware-in-the-loop (HIL) test of demand as frequency controlled reserve (DFR)

Abstract

This paper presents the hardware-in-the-loop (HIL) test of the demand as frequency controlled reserve (DFR). The HIL test refers to a test in which parts of a pure simulation have been replaced by actual physical components. It is used to understand the behavior of a new device or controller. The DFR has been tested by offline simulations to illustrate the efficacy of this technology. 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.

“…The parameters of TCLs are listed in Table II. P rate and COP are derived from the installed Bosch EHP AA 6.5 Air Source Heat Pump (ASHP), according to [21]. Due to the variety of different customers, P rate is assumed uniformly distributed between 6 kW and 8 kW.…”
