“…To achieve better power quality, to reduce the size and cost of the output filter, control complexity, reliability and availability, the selection of inverter configuration is the main challenge [50]. In [51], different topologies found in the literature are summarized. The main differences are found according to the number of legs; PWM levels and the type of filters used.…”

In the past decade, inverter-integrated energy sources have experienced rapid growth, which leads to operating challenges associated with reduced system inertia and intermittent power generation, which can cause instability and performance issues of the power system. Improved control schemes for inverters are necessary to ensure the stability and resilience of the power system. Grid-forming inverters dampen frequency fluctuations in the power system, while grid-following inverters can aggravate frequency problems with increased penetration. This paper aims at reviewing the role of grid-forming inverters in the power system, including their topology, control strategies, challenges, sizing, and location. In order to facilitate continued research in this field, a comprehensive literature review and classification of the studies are conducted, followed by research gaps and suggestions for future studies.

“…Various topologies of the shunt‐connected static distribution compensator (DSTATCOM) for power quality enhancement have been suggested by the researchers, that is, single‐phase, three‐phase three‐wire, and three‐phase four‐wire strategies 5,6 . In Maurya et al 7 and Huang et al, 8 a single‐phase DSTATCOM topology is presented for the residential system, whereas in Naqvi and Singh 4 and Singh et al, 5 the three‐phase three‐wire and three‐phase four‐wire topologies are presented.…”

SummaryThis paper presents the performance of a single‐phase utility‐tied distribution static compensator (DSTATCOM) with nonlinear load operating under weak grid conditions. The DSTATCOM is controlled by a complex kernel risk‐sensitive p‐power (CKRSP) algorithm. Ever‐increasing nonlinearity of the load, rapidly increasing renewable energy system installed capacity, and rising heating loads, especially during the winter season, lead to various power quality issues that worsen during weak grid conditions. An advanced adaptive control scheme, that is, CKRSP, enforces the system to perform various multifaceted operations, including harmonics suppression, handling rapid load variations, voltage sag and swell, and active and reactive power control at the point of common coupling (PCC) during weak grid conditions. The proposed CKRSP algorithm outperforms conventional control algorithms regarding steady‐state error, convergence speed, and accuracy. During weak grid conditions, the proposed system ensures stable DC bus voltage with a reduced second harmonic component. This further assists the CKRSP control in better extracting the fundamental load current component using a smoother loss component of current . The proposed system can handle various power quality issues during weak grid conditions while ensuring the overall system's stability. The laboratory prototype results show that the presented system performs satisfactorily under weak grid conditions per IEEE 519‐2014 standards.

“…Li et al, 2021;Rocabert et al, 2012). O controle formador de rede, também é conhecido na literatura como controle V-f e é utilizado principalmente em sistemas UPS e microrredes ilhadas, pois nestes casos a frequência e a amplitude da tensão devem ser controlados de forma autônoma, ou seja, sem suporte da rede elétrica (Antunes et al, 2017;Lliuyacc et al, 2017;Rajesh et al, 2017;Zhang, C. et al, 2016). Deve ser destacado que neste tipo de controle existe a necessidade de controlar a potência fornecida à microrrede para manter o balanço carga-geração.…”

“…Como consequência, a segunda estratégia consiste na GD suprir simultaneamente potência ativa e a parcela de correntes não lineares das cargas locais, a fim de fornecer/drenar unicamente correntes puramente senoidais. Neste caso o inversor seria controlado a operar tanto como FAPP, bem como sistema de GD, similar aos conversores multifuncionais estudados em (Brandão, Marafão, Paredes, et al, 2013;Busarello et al, 2018;Campanhol et al, 2017 (Gothner et al, 2019;Lorzadeh et al, 2017;Micallef et al, 2017;Peng, Shuai, Liu, et al, 2020;Sreekumar e Khadkikar, 2016, 2017.…”
