“…In [19], the impact of power amplifier (switched mode) on the stability of PHIL setups was analyzed and concluded that the approximation of power amplifier as time delay in s-domain was inappropriate as the power amplification itself impacted the stability of the PHIL setup. A number of techniques to improve the stability of PHIL setups have been proposed, such as the addition of hardware inductance in [26], feedback current filtering in [27], shifting impedance method in [17], multi-rate partitioning in [28], multi-time-step transmission line interface in [29], use of open-loop inverter as power amplifier in [30], with a comparison of a few of these approaches ( [17], [26]- [28]) presented in [31].…”

“…P HIL simulation, an advanced and efficient tool incorporating the physical power apparatus and large-scale power network into a real-time testing environment, has been widely utilized to promote the research and development in the power industry [1]- [11]. Owing to the merit of carrying out repeated, non-destructive, and in-depth investigation of the power apparatus and their interactions with the power network, PHIL has been extensively employed for prototyping applications [4]- [6], the verification of novel control paradigm [7], the black start testing of grid-forming converter [8], or the dynamic modelling and prototyping of renewable energy systems, such as variable-speed wind turbines [10], solar energy [6], and energy storage resources [5], [11].…”

“…The impact of the non-ideal characteristics and the dynamics stemming from the PI on the PHIL system stability and accuracy has been extensively discussed in literature [20]- [24]. Many research efforts have been devoted to improve the stability and accuracy of the PHIL simulation, such as the impedance shifting method [4], multi-rate partitioning interface [19], Bergeron transmission line model based multitime-step interface [6], Smith-predictor based compensation [23], H ∞ optimal control based interface [5], the optimal compensation filter design [24], and other advanced methods as summarized in [25]. Detailed modelling principles, block diagrams, stability criteria, and accuracy metrics have been developed for the assessment of system properties such as stability and accuracy of respective approaches.…”

“…Most of the contributions on PHIL in the literature acknowledge that time delay is important [13]- [23], however a detailed study of time delay has not been published yet. Appropriate understanding of the time delay and its effect will lead to a reduced risk of instabilities and inaccuracies when performing PHIL experiments, allowing more resilient and accurate evaluation of complex power components [24]. A thorough characterization of delays in PHIL can also help to reduce the total loop delay and increase its accuracy.…”
