(2022-06-13)
Article
Open AccessAn in-depth study of harmonic current reduction in European commercial buildings due to the harmonic cancellation effect when a set of single-phase uncontrolled rectifiers and a set of fluorescent lamps are connected at ... -
Aportacions a la modelització de la màquina d'inducció de gàbia d'esquirol
(Universitat Politècnica de Catalunya, 2013-07-27)
Doctoral thesis
Open AccessEn aquesta tesi es tracten en profunditat diversos aspectes sobre la modelització de la màquina d’inducció de gàbia d’esquirol. En el primer capítol, a partir dels paràmetres i de les característiques elèctriques i ... -
Assessment of subsynchronous oscillations in AC grid-connected VSC systems with type-4 wind turbines
(2019-12-09)
Article
Open AccessConverters are the key for increasing the development of renewable energy generation but their dynamic interaction with the grid has an important impact on stability. Oscillatory instabilities in different grid-connected ... -

Comparison of simplified models for voltage-source-inverter-fed adjustable-speed drive during voltage sags when the during-event continue mode of operation is active
(2014-11-13)
Article
Restricted access - publisher's policyThree simplified models for adjustable-speed drives are compared with measurements on an actual drive where the inverter control strategy remains unaltered during the event (also known as continue mode of operation) to ... -
Comparison of small-signal admittance-based models of doubly-fed induction generators
(2023-02)
Article
Restricted access - publisher's policyThis paper reviews and compares the main doubly-fed induction generator (DFIG) models for stability assessment in the literature by PSCAD/EMTDC simulation. The main contribution of the paper is a detailed study on small- ... -
DC Admittance Model of VSCs for Stability Studies in VSC-HVDC Systems
(2023-07-01)
Article
Open AccessHigh-voltage direct current (HVDC) systems linked to AC grids with converters are promising energy transmission systems. These systems present complex AC- and DC-side dynamic interactions. Impedance-based stability studies ... -
Disseny d’un generador eòlic de petita potència
(Universitat Politècnica de Catalunya / Universitat de Barcelona, 2009-06)
Master thesis
Open AccessEn l’actualitat l’energia eòlica està assolint un protagonisme molt important en termes de grans parc de molt alta potència per generador. Tanmateix, un segment encara poc desenvolupat però amb símptomes d’un gran creixement ... -
Effect of wind turbine converter control on wind power plant harmonic response and resonances
(2017-02-01)
Article
Restricted access - publisher's policyWind turbine harmonic emissions due to power electronics are a well-known power quality concern in wind power plants (WPPs). This problem may be increased by resonances because they amplify harmonic distortion around ... -
