“…The transistors are controlled by the SVM predictive method (Space Vector Modulation). The method used was described in detail by the authors of [29]. It is a non-linear method [30] belonging to the group of methods with a Continuous Control Set of output voltage vectors based on Model Predictive Control (CCS-MPC).…”

“…Along with the increase of the distortion time related to the frequency delta, the value of the U GridRMS voltage in the separated circuit slightly decreased during the detection process, despite the constant value of the reference current (yellow wave). The lower value of the voltage in the islanded network results from the current control mode of the converter [29]. The voltage in the network is not a regulated quantity.…”

The article presents a modified standard Active Frequency Drift (AFD) method used to detect unintentional island operation in converters generating electricity from renewable energy sources to the power grid. The primary aim of each of the island operation detection methods is the possibility of shortening the energising of a separate part of the power grid. The proposed method eliminates fragments of the reference current signal when it reaches a constant value for a particular time. This part of the signal is replaced with the hyperbolic sine function. It allows reducing the value of Total Harmonic Distortions (THD) while maintaining the same effectiveness of island operation detection. The article contains a detailed description of the newly proposed type of disturbance generation. The proposed solution is verified by conducting simulation and laboratory tests. The possibility of shortening the island operation detection time is proven by increasing the maximum distortion introduced into the current without exceeding the permissible THD limit for converters connected to the power grid.

“…To date, passive compensators are used in conjunction with power electronic filters (known as active power filters), forming hybrid systems [13,15,22,26,27]. In principle, the approach to hybrid systems is relatively basic, as it involves fitting capacitors or chokes for a chosen amount of reactive power and then adding a power electronics system to compensate for the remaining reactive power, which is a significantly lower value [26][27][28][29][30].…”

This article presents methods of reactive power compensation using passive elements in the form of a capacitor (C) or choke (L) and an LC structure selected in such a way as to lead to the minimization of the reactive current (reactive power) of a single-phase system. The adaptation of the parameters of a passive compensator, reducing reactive power and/or distortion power, was possible through the extended Budeanu theory. In addition, through the extended Budeanu theory and also through the knowledge of the equivalent parameters of the linear load, the obtained results of the increase in distortion power, depending on the structure of the passive compensator, were analyzed. The values listed in the tables, as well as the waveforms of the component currents of a single-phase linear load, were obtained based on calculations and simulation models in MATLAB/Simulink software R2023a.
