Power Hardware in the Loop (PHIL) systems are used to test a power system with the help of combined software and hardware. Generally, to construct a PHIL system, a switched-mode power amplifier that has a stable performance is used, because of their large, linear signal control-to-output characteristics. However, the fundamental limitations of a switch-mode power amplifier (PA) are the dynamic performance and output bandwidth. In this paper, a compound controller has been used for the rectifier part of a PA, which can ensure the stability of a PA under transient or fault operating conditions. Moreover, a compound controller, which involves a feed-forward controller, a proportional controller and a repetitive controller, is proposed in the inverter part of a PA, and it can be used for PHIL applications. Experimental results are obtained under various operating conditions, such as transient responses under load step change, and output voltage bandwidth testing for a PHIL system, it is concluded that a proposed switched-mode power amplifier is useful for the PHIL system.

“…In this way, the monitoring and control hardware/software can be readily evaluated and, if necessary, fine-tuned or debugged before interconnection with the actual power system. Recently, there has been impetus to extend HIL concepts to interconnect computer models of selected components/subsystems, such as individual motor drives or generators, with the actual power system at the higher voltage and power levels commensurate with the power system [6]- [8]. Specifically, in [6] the dynamics of an inverter/induction machine is studied using a hardware-based inverter and a real-time simulation of an induction machine.…”

“…In [8], the researchers suggest possible approaches to partition hardware/software components for ac radial distribution systems. As described in [6]- [8], an HIL in which models and hardware are interconnected at the voltage/power levels of the power system [herein referred to as model-in-the-loop (MIL)] capability enables system integrators to identify potential source/load interactions and, if necessary, address these issues through computer modeling, thereby reducing risk and overall implementation costs.…”

Abstract-A model-in-the-loop capability (MIL) has been developed to emulate the dynamics of alternative power sources in a hardware-based dc zonal electrical distribution system. Using this tool, models of the power sources are simulated in real-time and interfaced with hardware components at the voltage and current levels of the power system. Coupling between simulation and hardware is established through a dc/dc power converter using model/wall-clock time synchronization. The MIL capability is illustrated in the emulation of a synchronous machine/converter power source. Results of time-domain and frequency-domain studies are provided to validate the approach.

“…There lacks a generalized discussion of how to implement power HIL simulations, especially the selection of interface algorithms. A generic design procedure is proposed in [11]. But the discussion stops at an abstract level, making it difficult to be applied in practice.…”

the closed-loop stability and the simulation accuracy are two paramount issues in power Hardware-In-the-Loop simulation in regard to the operational safety and the experiment reliability. In this paper, the stability issue of the Power HIL simulation is first introduced with a simple example. A stability analysis and accuracy estimation method based on the system's loop transfer function is later given. Five different interface algorithms are described and their respective characteristics with respect to the system stability are compared. Through Matlab simulations and field experiments of two representative Power HIL examples, it is revealed that certain interface algorithms exhibit higher stability and accuracy than the others under the given conditions. A recommendation for selecting appropriate interface algorithms is finally proposed at the end of the paper.
