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 ...
Equivalence of primary control strategies for AC and DC microgrids
(MDPI, 2017)
Microgrid frequency and voltage regulation is a challenging task, as classical generators with rotational inertia are usually replaced by converter-interfaced systems that inherently do not provide any inertial response. ...
Dual Inertia-Emulation Control for Interlinking Converters in Grid-Tying Applications
(IEEE, 2021)
Electric grids are undergoing several changes, mostly driven by the replacement of classical highly-inertial generators by converter-interfaced generation and storage systems. This entails the reduction of inherent inertia ...
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 ...
Stability tool for electric power systems with a high penetration of electronic power converters
(Elsevier B.V., 2022)
The increasing use of electronic converters is making possible the development of more sustainable, efficient, and reliable electric power systems, but it is also introducing new challenges that need to be addressed. Power ...
Hybrid ac/dc microgrids. Part I : Review and classification of topologies
(Elsevier, 2015)
Microgrids have been widely studied in the literature as a possible approach for the integration of distributed energy sources with energy storage systems in the electric network. Until now the most used configuration has ...
Comparative small-signal evaluation of advanced grid-forming control techniques
(Elsevier B.V., 2022)
This paper presents the small-signal modelling and analysis of the most recent grid-forming control techniques, namely the matching control (MC) and the dispatchable virtual oscillator (dVOC). These are compared to more ...
Droop control operation strategy for advanced DC converter-based electrical railway power supply systems for high-speed lines
(Elsevier Ltd., 2022)
Advanced DC converter-based electrical railway power supply systems are very promising power supply configurations for the electrification of high-speed lines. Their full controllable converter-based traction substations ...
Hybrid ac/dc microgrids. Part II : Review and classification of control strategies
(Elsevier, 2015)
Microgrids are envisioned as one of the most suitable alternatives for the integration of distributed generation units in the utility grid, as they efficiently combine generation, energy storage and loads in the same ...
