Analytical Modeling Approach to Study Harmonic Mitigation in AC Grids with Active Impedance at Selective Frequencies
(MDPI AG, 2018)
This paper presents an analytical model, oriented to study harmonic mitigation aspects in
AC grids. As it is well known, the presence of non-desired harmonics in AC grids can be palliated
in several manners. However, in ...
Power Balancing in Cascaded H-Bridge and Modular Multilevel Converters Under Unbalanced Operation: A Review
(IEEE, 2021)
Multilevel Voltage-Source Converters (VSC) based on modular structures are envisioned as a prominent alternative for grid and industry applications. Foremost among these are the Cascaded H-Bridge (CHB) and the Modular ...
Reactive power limits of Cascaded H-Bridge STATCOMs in star and delta configuration under negative-sequence current withstanding
(Elsevier Ltd., 2022)
Flexible AC Transmission System devices (FATCS) and in particular Static Synchronous Compensators (STATCOM) play a key role in the evolution of the modern power grids to the future smart grids. The STATCOM is used in an ...
Zero-sequence controller requirements and comparison for a delta-CHB STATCOM under unbalanced operation
(Elsevier, 2024)
Delta-configured Cascaded H-Bridge (DCHB) topology is a suitable alternative for Static Synchronous Compensator (STATCOM) applications. However, under unbalanced voltage and/or current conditions, zero-sequence current ...
