“…Due to different operating conditions between CSC and VSC, its application on the latter remains to be investigated. Wavelet transform has been popularly researched for disturbance study in conventional power system, some literature supports that it can applied to HVDC system too [17,18,19]. However, the wavelet-based method typically requires thresholding.…”

“…Internal fault location in an HVDC line is executed through a detection criterion utilizing the phase-frequency information extracted from the complex WT applied to a DC current signal [82]. The sheath voltage of positive and negative cables is processed through WT to extract the detail coefficients during several kinds of faults in a VSC-HVDC system [120]. Proper thresholding is provided for differentiating the AC and DC faults [121].…”

The extensive application of power transfer through high-voltage direct current (HVDC) transmission links in smart grid scenarios is due to many factors such as high-power transfer efficiency, decoupled interconnection, control of AC networks, reliable and flexible operation, integration of large wind and photovoltaic (PV)-based off-shore and on-shore farms, cost-effectiveness, etc. However, it is vital to focus on many other aspects like control, protection, coordinated operation, and power management to acquire the above benefits and make them feasible in real-time applications. HVDC protection is needed to focus further on innovative and devoted research because the HVDC system is more vulnerable to system faults and changes in operational conditions in comparison to AC transmission because of the adverse effects of low DC-side impedances and sensitive semi-conductor-based integrated power electronics devices. This paper provides a comprehensive review of the techniques proposed in the last three decades for HVDC protection, analyzing the advantages and disadvantages of each method. The review also examines critical findings and assesses future research prospects for the development of HVDC protection, particularly from the perspective of smart-grid-based power systems. The focus of the review is on bridging the gap between existing protection schemes and topology and addressing the associated challenges and issues. The aim is to inform power engineers and researchers about potential research avenues to tackle the challenges in HVDC protection in smart-grid-based power systems.

This paper presents the procedures for universal models preparation of components and devices that can be used in various simulation software environments that can be used for electro-thermal systems analysis. Such approach is applicable for multiphysical analyses in areas such as electrical engineering, electronics and physics. The proposed method that involves generation of DLL libraries is explained based on multiphysical model comprising electric and thermal subsystems. The paper highlights a complementary benefit of models black-boxing that may play an important role for know-how protection. The analyses performed herein revealed that proposed universal models are able to produce credible quantitative results in case of all considered software environments (PSCAD, Matlab, DIgSILENT), however with significant differences in the recorded computation time. Streszczenie. Niniejszy artykuł przestawia metodę przygotowania uniwersalnych modeli komponentów, możliwych do użycia w różnych środowiskach symulacyjnych służących do analiz multifizyczyny w dziedzinach takich jak elektrotechnika, elektronika i fizyka. Zaproponowana metodyka uwzględniająca generację bibliotek DLL została przedstawiona w oparciu o multifizyczny model składający się z części termicznej i elektrycznej. Przeprowadzona analiza wykazała dużą zbieżność wyników pomiędzy rozpatrywanymi programami symulacyjnymi (PSCAD, Matlab, DIgSILENT), jednakże z zauważalnymi różnicami w długości trwania obliczeń. Uniwersalne modele komponentów bazujące na bibliotekach DLL do symulacji multifizycznych systemów elektro-termicznych
