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. ...
Evaluation of the frequency response of AC transmission based offshore wind farms
(InTech Europe, 2011)
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 ...
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 ...
Impedance-Based Stability Evaluation of Virtual Synchronous Machine Implementations in Converter Controllers
(IEEE, 2018)
This paper presents a stability evaluation of two Virtual Synchronous Machine (VSM) implementations in the control of Voltage Source Converters (VSCs): a current-controlled (CCVSM) and a voltage-controlled (VCVSM) version ...
Experimental test bench for testing DC microgrid control strategies
(IEEE, 2017)
During the last decades the number of microgrids and their research have increased notably, as they offer a high versatility for the integration of distributed generation (DG) units and renewable energies. Among the different ...
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 ...
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 ...
