“…Afterward, the analogous strategy to obtain unterminated models is applied to this kind of models in [33]. Furthermore, a detailed description of the tests needed to perform the identification of three-phase Voltage Source Inverters (VSI) is presented in [34]. Finally, a preliminary work to consider the large-signal behavior of grid-connected DC-AC converters with droop control is presented in [35] at simulation level.…”

Modern electric power distribution systems are progressively integrating electronic power converters. However, the design of electronic-power-converter-based systems is not a straightforward task, as the interactions among the different converters can lead to dynamic degradation or instabilities. In addition, electric power distribution systems are expected to consist of commercial-off-the-shelf converters, which implies limited information about the dynamic behavior of the devices. Large-signal blackbox modeling approaches have been proposed in order to obtain accurate dynamic models of commercial converters that can be used for system-level analyses. However, most of the works are focused on DC-DC converters. In this work, a large-signal blackbox model is proposed to model grid-connected three-phase DC-AC converters. An experimental setup has been used to demonstrate the limitations of small-signal models and the capability of the proposed modeling approach to capture the dynamic behavior of the converter when large perturbations are applied. Finally, the automation of the model identification process is discussed.

“…The most advantageous solution can be derived in the three-level PWM rectifier, and the three-phase buck plus boost PWM rectifier topology proposed in [35] was demonstrated to have a high system reliability, since the output capacitor is not required to be charged in advance and load current limitation for the short circuit case is avoided for startup. In addition, the black-box modelling of three-phase voltage source inverters (VSIs) was carried out in [36] for system-level analysis in MEA, where the model is simple, the large-signal behaviour of the converter can be derived, and no internal data is required for the converter. On top of that, for the purpose of eliminating the harmonics produced by the on-board nonlinear loads, the design of a fully digitally controlled 400-Hz active power filter (APF) was presented for aircraft applications in [37].…”

“…For example, References [10,11] studied identification modeling method of DC/DC converter, and nonlinear models were selected to describe converters' output behaviors. In Reference [12], the black-box modeling process for a single three-phase inverter was proposed, and the dynamic parameters of the system were obtained through the step response. Moreover, the model also took the effects of cross-coupling into account, which further improved the accuracy of the model.…”

The voltage and frequency response model of microgrid is significant for its application in the design of secondary voltage frequency controller and system stability analysis. However, most models developed for this aspect are complex in structure due to the difficult mechanism modeling process and are only suitable for offline identification. To solve these problems, this paper proposes a black-box modeling method to identify the voltage and frequency response model of microgrid online. Firstly, the microgrid system is set as a two-input, two-output black-box system and can be modeled only by data sampled at the input and output ports. Therefore, the simplicity of modeling steps can be guaranteed. Meanwhile, the recursive damped least squares method is used to realize the online model identification of the microgrid system, so that the model parameters can be adjusted with the change of the microgrid operating structure, which makes the model more adaptable. The paper analyzes the black-box modeling process of the microgrid system in detail, and the microgrid platform, including 100 kW rated power inverters, is employed to validate the analysis and experimental results.
