“…Switching models established using commercial simulation tools such as PSIM, EMTP, and MATLAB/ Simscape provide insight into the inverter's dynamics and its interaction with the grid [4]. These models allow for various studies, including (i) efficiency assessment and power loss calculations [5], (ii) evaluation of deadtime effect on inverter performance [6][7][8], (iii) investigating harmonic content for facilitating filter design [9] or verifying harmonic compensation techniques [10], (iv) examination of DC bus utilization [11], and (v) investigation into the impact of PWM scheme on inverter operation [12]. The advantage of such switching models is to represent faithfully the inverter behavior in real practice.…”

This paper presents a performance comparison between switching and reduced-order models of grid-following inverters. Different models have been developed to study the inverter’s operation using MATLAB and PSIM simulation tools. These models offer a tradeoff between accuracy and computational burden. The switching model fully represents the discontinuities in the inverter due to switching, but such a model demands high computational resources. The inverter representation is simplified using reduced-order models, which is common in the literature. However, the fidelity of these simplified models might not be adequate for some applications. Therefore, it is essential to investigate the performance of such models closely to ensure their suitability depending on the purpose of the analysis. Hence, a comparative study between switching and reduced-order models is presented here by simulating different scenarios and operation conditions. The results have validated the efficacy of the reduced-order model in representing the grid-following inverter’s operation in both steady state and response to a step change resulting from active or reactive power variation. Unlike the switching model, the findings illustrate that the reduced-order modeling fails to represent harmonics and losses. After simulating different scenarios, this work highlights the main differences between the switching and reduced-order models to facilitate the choice of the proper modeling method for researchers.
