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 ...
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 ...
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 ...
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 ...
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 ...
Hybrid AC/DC microgrid mode-adaptive controls
(InTech, 2017)
The lack of inertial response at microgrids is usually compensated by configuring primary controllers of converter‐interfaced devices to contribute in the transient response under power disturbances. The main purpose of ...
A Dynamic Frequency-and-Voltage Power Flow Simulation Tool for Hybrid AC/DC Power Systems based on Simulink
(IEEE, 2022)
A more renewable energy generation model entails the replacement of synchronous generator-based power plants by converter-interfaced renewable sources, resulting in more susceptible power systems in terms of frequency and ...
