Fault-Ride-Through Coordination Strategy for Offshore AC Islands with Multi-Infeed HVDC Interconnections
Eleni Tsotsopoulou, Vasileios Psaras, Dionysios Moutevelis +2
Large-scale offshore Wind Farms (WFs) are considered key assets towards realizing a sustainable power system. These systems are often configured as offshore AC islands and their in…
Open-source implementation of distribution network reconfiguration methods: Analysis and comparison
Ferran Bohigas-Daranas, Oriol Gomis-Bellmunt, Eduardo Prieto-Araujo
This paper presents a critical and practical approach to the evolution of distribution network reconfiguration algorithms, tracing their development from foundational heuristic met…
Shaping Frequency Dynamics in Modern Power Systems with Grid-forming Converters
Carlos Collados-Rodriguez, Daniel Westerman Spier, Marc Cheah-Mane +2
In this paper, frequency dynamics in modern power systems with a high penetration of converter-based generation is analysed. A fundamental analysis of the frequency dynamics is per…
Cell-based VSC Analysis Methodology: From Graph Laplacian to Converter Degrees of Freedom
Daniele Falchi, Eduardo Prieto-Araujo, Oriol Gomis-Bellmunt
Power-electronics-based converters are being considerably employed through the power system to interconnect multiple heterogeneous electrical layers. Furthermore, the intrinsic ver…
Data-Driven Decision Making for Enhancing Small-Signal Stability in Hybrid AC/DC Grids Through Converter Control Role Assignment
Francesca Rossi, Sergi Costa Dilme, Josep Arevalo-Soler +2
Hybrid AC/DC transmission grids incorporate Modular Multilevel Converters functioning as Interconnecting Power Converters (IPCs). The control role assigned to each converter signif…
A Dynamic Similarity Index for Assessing Voltage Source Behaviour in Power Systems
Onur Alican, Dionysios Moutevelis, Josep Arevalo-Soler +5
Due to the fundamental transition to a power electronic dominated power system, the increasing diversity of dynamic elements underscores the need to assess their similarity to matu…
