“…Existing literature lacks an efficient voltage dip detection method that aligns with LVRT schemes. While digital signal processing methods have been extensively explored for signal analysis across various applications, the Goertzel algorithm stands out for its simplicity and speed in evaluating signal characteristics with minimal computations, making it promising for power system applications [28][29]. However, the Goertzel's voltage dip detection scheme [14] fails to respond quickly enough for LVRT conditions.…”

Low-voltage ride-through (LVRT) is one of the most important criteria for integrating wind energy into the power grid. Based on grid connection codes, wind generators must remain connected during fault conditions. However, this requires a careful protection scheme design for addressing the successful ride through of the brushless doubly fed induction generator (BDFIG) during severe voltage dips. This paper proposes a comprehensive solution for enhancing the BDFIG ride through during asymmetrical faults. Furthermore, since the proposed solution is dependent on the type and severity of voltage dips, an updated harmonic resilient scheme is developed to detect the dip level and type of faults. Performance of the proposed protection scheme is investigated for further improvement of the brushless DFIG LVRT capability based on series dynamic resistor (SDR) circuit design in order to limit post-fault oscillations. With the proposed solution, the BDFIG can satisfy ride through requirements for severe voltage dip scenarios. The proposed framework which includes a voltage detection method, appropriate SDR value determination procedure, and SDR control circuit was implemented and validated with a coupled circuit model in MATLAB/Simulink for a BDFIG prototype.INDEX TERMS Brushless doubly fed induction generator, low voltage ride-through, series dynamic resistor, grid code, voltage dip detection.

“…Međutim, u realnom slučaju ovo nije uvek ostvarivo, pa su potrošači podvrgnuti raznim smetnjama, od kojih su najnezgodniji propadi napona. Oni mogu da izazovu trenutan prekid rada pogona (reagovanje podnaponskih zaštitnih relea) ili resetovanje računara is l., što ima i značajne finansijske posledice [1][2][3]. Da bi se obezbedio nesmetan rad potrošača i umanjile posledice po elektroenergetski sistem u slučajevima propada napona, preduzimaju se mere u dva pravca.…”

“…Kako bi se obezbedila stabilnist mreže za vreme kvarova u slučaju velikog učeća ovakvih izvora potrebno je da oni imaju LVRT sposobnost. Ona podrazumeva da elektrana nastavlja da pruža podršku mreži za vreme propada napona injektiranjem odgovarajuće aktivne i reaktivne snage u zavisnosti od propada napona [3,5].…”

Očekuje se da vetroelektrane iskažu sposobnost da pružaju podršku mreži u toku propada napona (tokom kvara) u skladu sa zahtevima LVRT i da time utiču da se poboljšaju naponske prilike [3].…”

There is a global trend to reduce emissions from cars through the adoption of other alternatives, such as electric vehicles (EVs). The increasing popularity of EVs has led to a growing demand for electric vehicle chargers. EV chargers are essential for charging the batteries of EVs. Since the EV charger stays connected to the grid for long periods of time to charge the EV battery, it must be able to handle disturbances in the power grid. The goal of this paper is to present an overview of the impact of grid events on EV battery chargers. As well as the impact of grid unbalances on EV chargers, this paper also provides an overview of the impact of grid faults on other, similar power electronics interfaced resources such as PV and energy storage systems.
