Quantifying Power to Voltage and Frequency Dynamics for Oscillation Propagation Assessment
Onur Alican, Dionysios Moutevelis, Marc Cheah-Mañe +2
The integration of Inverter-Based Resources (IBRs) into power systems introduces multi-timescale dynamics and oscillations which may propagate to distant areas and endanger the saf…
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…
A Matlab-based Toolbox for Automatic EMT Modeling and Small-Signal Stability Analysis of Modern Power Systems
Josep Arevalo-Soler, Dionysios Moutevelis, Elia Mateu-Barriendos +5
The intensive integration of power converters is changing the way that power systems operate, leading to the emergence of new types of dynamic phenomena and instabilities. At the s…
Voltage Stability and Control of Electrical Distribution Systems with High Penetration of Power Electronic Converters
Dionysios Moutevelis
Power systems are currently undergoing a rapid paradigm change in their operation. Centralised energy production is being replaced by a number of Distributed Generation (DG) units…
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…
Equivalent modelling for the fundamental frequency dynamic variation: State-space, impedance, and power-frequency representations
Pablo Rodriguez-Ortega, Dionysios Moutevelis, Javier Roldan-Perez +1
Stability of power electronic converters connected to power grids is commonly assessed by using the impedance criterion while the stability of power grids is typically analysed by…
Recursive Secondary Controller for Voltage Profile Improvement Based on Primary Virtual Admittance Control
Dionysios Moutevelis, Javier Roldan-Perez, Njegos Jankovic +1
This paper proposes a recursive, virtual admittance based, secondary controller for DG units that improves the voltage profile in distribution networks. First, the adaptation of th…
Taxonomy of Power Converter Control Schemes based on the Complex Frequency Concept
Dionysios Moutevelis, Javier Roldan-Perez, Milan Prodanovic +1
This paper proposes a taxonomy of power converter control schemes based on the recently proposed concept of complex frequency. This quantity captures local frequency variations due…
