State-space model of qZSI based PMSG-WPGSs for transient dynamic studies
(2021-09)
Conference lecture
Restricted access - publisher's policyThe use of permanent magnet synchronous generators (PMSGs) with full-scale back-to-back converters is rising as a common option in wind power generation systems (WPGSs). An efficient grid integration of PMSG-WPGSs is ... -
Explore courses: virtual vs face-to-face
(2020)
Conference report
Restricted access - publisher's policyThe “EXPLORATORI” is a project from the Universitat Politècnica de Catalunya (UPC) and the Berga Town Council. The main objective of the project is to bring science closer to secondary school students, their teachers and ... -
On resonance instabilities in VSCs connected to weak grids
(2019)
Conference report
Restricted access - publisher's policyThis paper addresses the oscillatory stability phenomena studied in the literature and reported by network operators in grid-connected VSC systems. Negative interactions have been observed at different frequencies in these ... -
Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability
(2009)
Conference lecture
Open AccessThis paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ... -

DC-DC buck converter parameter identification based on a white-box approach
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessThis paper proposes to use a white-box approach to identify the parameters of an electronic DC-DC buck converter. It discretizes the differential equations governing the dynamic of such system, which are used to identify ... -
Detailed off-line parameter identification of synchronous generator based on frequency response tests
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessThis work presents a general methodology, based on standstill frequency response tests. Once the circuit topology is chosen, it allows a systematic calculation of the circuit parameters for a salient pole synchronous ... -
Modeling and control of a three-phase grid-connected inverter under fault conditions
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThe aim of this paper is to study the behavior of a three-phase inverter with an RL filter powered by a renewable energy source and connected to a grid under fault conditions. The novelty of the work lies in proposing a ... -
Power control strategies during voltage sags according to Spanish grid code
(2018)
Conference report
Open AccessIn order to connect any power converters into the grid there are some grid requirements to insure the safe operation of the grid. So, the control of the converters especially during abnormal ... -
