Apparent impedance analysis: A new method for power system stability analysis
Rygg, Atle; Amin, Mohammad; Molinas Cabrera, Maria Marta; Gustavsen, Bjørn Alfred (IEEE Workshop on Control and Modeling for Power Electronics, COMPEL;2016, Chapter, 2016)In this paper a new method for power system stability analysis is introduced. The method is based on injection of a small voltage or current in an arbitrary point of the system. The apparent impedance is defined as the ... -
Exploring the Potential for Increased Production from the Wave Energy Converter Lifesaver by Reactive Control
Sjolte, Jonas; Sandvik, Christian Mclisky; Tedeschi, Elisabetta; Molinas Cabrera, Maria Marta (Journal article; Peer reviewed, 2013) -
High-Power Machines and Starter-Generator Topologies for More Electric Aircraft: A Technology Outlook
Nøland, Jonas Kristiansen; Leandro, Matteo; Suul, Jon Are Wold; Molinas Cabrera, Maria Marta (Peer reviewed; Journal article, 2020)More electric aircraft (MEA) architectures consist of several subsystems, which must all comply with the settled safety requirements of aerospace applications. Thus, achieving reliability and fault-tolerance represents the ... -
Optimal Shaping of the MMC Circulating Currents for Preventing AC-side Power Oscillations from Propagating into HVDC Grids
Bergna-Diaz, Gilbert; Suul, Jon Are Wold; Berne, Erik; Vannier, Jean-Claude; Molinas Cabrera, Maria Marta (Journal article; Peer reviewed, 2019)A constrained optimization problem based on the Lagrange multipliers method is formulated to derive the circulating current references of Modular Multilevel Converters (MMC) directly in abc coordinates. The resulting ... -
Parametric Stability Assessment of Single-Phase Grid-Tied VSCs Using Peak and Average DC Voltage Control
Chen, Zhang; Isobe, Takanori; Suul, Jon Are Wold; Dragicevic, Tomislav; Molinas Cabrera, Maria Marta (Peer reviewed; Journal article, 2021) -
Static and dynamic eigenvalues in unified stability studies
Khodaparast, Jalal; Fosso, Olav B; Molinas Cabrera, Maria Marta; Suul, Jon Are Wold (Peer reviewed; Journal article, 2022)A framework for unified analysis of small-signal and large-signal power system stability based on static and dynamic eigenvalues is proposed in this paper. The presented implementation is based on Gear's method, which is ... -
Switching sequences for non-predictive declutching control of wave energy converters
Garcia Rosa, Paula Bastos; Fosso, Olav B; Molinas Cabrera, Maria Marta (Peer reviewed; Journal article, 2021)Aiming at improving the energy absorption from waves, a number of studies have considered declutching control - a phase-control method that consists of disengaging the power take-off (PTO) system from the oscillating body ...
