“…Also, in this paper, time-domain simulations have been used to analyze the performance of VSC-HVDC for soft energization of major generating units. Similarly, [110] deals with functional validation of the control system of the HVDC interconnection between France and Spain to be employed in blackstart operation, using a real-time simulator.…”

More than thirty-six partial or whole blackouts, from 2016 to 2021, prove that neither the probability of blackouts can be ignored nor the required plans and the readiness of the utilities for power system restoration can be forgotten. To properly deal with blackouts and minimize the social and economic costs, utilities should prepare a suitable restoration plan in advance to quickly restore the system to the normal state and minimize the restoration time and loss of energy. In this paper, after summarizing major blackouts occurred from 2016 to 2021, the progress in the research reports, industrial documents, and books in the context of power system restoration is reviewed to show and classify the different aspects of power system restoration plans and strategies presented during these years. This review indicates that although there are many published methods and techniques which have tried to give more autonomous solutions, there are still more complexities in power system restoration. However, this paper respects all efforts and attempts and tries to illustrate the achievements, up to now, in power system restoration, as well as research gaps.

“…With the continuous progress of HVDC technology, DC transmission projects are developing rapidly all over the world. [1][2][3][4] As one of the core components in the process of DC transmission, the state of converter transformer will directly affect the reliability of power grid. [5][6][7] Compared with ordinary AC transformer, converter transformer will produce more harmonic and DC components due to the converter process, and then affect the grounding current.…”

When the converter transformer core is grounded at multi-points, a fault loop will be formed and a circulation will be generated, leading to local overheating of the magnetic core and decomposition of insulating oil. Therefore, the converter transformer core will be single point grounded. As a rare internal lead of converter transformer, the ground current on the core ground lead can often reflect the running state of converter transformer. In this paper, theoretical analysis, modeling simulation and experimental research are carried out on the ground current of converter transformer at one point. Firstly, according to the structure characteristics of converter transformer, the analytical modeling of ground current is carried out. Secondly, based on the structure characteristics of oil paper insulation, the equivalent capacitance of converter transformer is calculated. Then, the analytical and finite element simulation model of converter transformer is established, and the ground current of converter transformer is calculated. Finally, the correctness of the proposed scheme is verified by measuring the grounding current of converter transformer core.

Çok seviyeli inverterler (ÇSİ), iyileştirilmiş çıkış dalga formu ve azaltılmış harmonik distorsiyon gibi avantajlarıyla dikkat çekmektedir. Ancak, ÇSİ sistemlerinde hala harmonik sorunu bulunmaktadır. Araştırmacılar, bu sorunu çözmek için seçici harmonik eliminasyonu-darbe genişliği modülasyonu (SHE-PWM) tekniğini kullanmıştır. Ancak, seçilen harmoniklerin ortadan kaldırılması için gereken SHE denklemleri karmaşık ve yoğun hesaplamalar gerektirir. Bu makalede, ÇSİ'lerde SHE denklemlerini çözmek için nispeten yeni bir Afrika Akbabaları Optimizasyonu (AVO) algoritması sunulmaktadır. AVO tabanlı SHE-PWM tekniği, 7, ve 11 seviyeli kaskad ÇSİ üzerinde test edilmiştir. Önerilen algoritma, 0.1 ile 1.0 modülasyon indeksi aralığında uygun çözümler bulmayı başarmıştır. 0.5 ile 1.0 arasındaki modülasyon indeksi aralığında seçilen harmoniklerin başarılı bir şekilde yok edilebildiği ve temel gerilimin %0.5'ten daha az hata ile kontrol edilebildiği gözlenmiştir.
