A fundamental study on the impact of HVDC lines on transient stability of power systems
Sigrist, Lukas; Echavarren Cerezo, Francisco; Rouco Rodríguez, Luis; Panciatici, Patrick (Eindhoven University of Technology (Eindhoven, España), 29/06/2015)An increasing number of HVDC lines are currently deployed all around the world. HVDC links are either based on line-commutated converters (LCC) or on voltage-source converters (VSC) technologies. This paper presents a ... -
A simplified approach to detect undervoltage tripping of wind generators
Sigrist, Lukas; Rouco Rodríguez, Luis (Eindhoven University of Technology (Eindhoven, España), 29/06/2015)This paper proposes a simplified but fast approach based on a Norton equivalent of wind generators to detect undervoltage tripping of wind generators. This approach is successfully applied to a real wind farm. Today, most ... -

Dynamic virtual power plant: a new concept for grid integration of renewable energy sources
Marinescu, Bogdan; Gomis Bellmunt, Oriol; Dörfler, Florian; Schulte, Horst; Sigrist, Lukas (12/09/2022)The concept of Virtual Power Plant (VPP) has arisen over a decade ago from the relatively low competitiveness of the back then emerging non-dispatchable RES. A set of smaller generators imitates the behavior of large ... -
Energy storage systems for frequency stability enhancement in small-isolated power systems
Egido Cortés, Ignacio; Sigrist, Lukas; Lobato Miguélez, Enrique; Rouco Rodríguez, Luis; Barrado Sánchez, Alberto Carlos; Fontela Martínez, Pablo; Magriñá Sole, Jordi (European Association for the Development of Renewable Energies, Environment and Power Quality; Unive (La Coruña, España), 25/03/2015)Frequency stability is one of the most relevant issues in operation of small isolated power systems. High penetration of renewals may significantly affect frequency stability of isolated power systems since renewable energy ... -

Improving scalability and replicability of smart grid projects
May, Kristof; Sigrist, Lukas; Vingerhoets, Pieter; Morch, Andrei; Verboven, Peter; Rouco Rodríguez, Luis (Association des Economistes de l'Energie (París, Francia), 04/06/2015)Today most smart grid projects are still in the R&D or the demonstration phases on small scale. The condition that these projects are implemented in the future on a large scale is that they have a suitable degree of ...
