Photovoltaic inverters with fault ride-through capability
(ISIE, 2009)
Conference lecture
Open AccessThis paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in ... -
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 ... -
Influence of the ICFF decoupling technique on the stability of the current control loop of a grid-tied VSC
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThe control scheme of grid-tied converters is often implemented in the dq-frame due to simplicity of design. However, with this transformation, there exists an inherent cross-coupling term between the d-and q-channels which ... -
