Frequency-adaptive virtual flux estimation for grid synchronization under unbalanced conditions
Suul, Jon Are; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Undeland, Tore (2011)
Text en actes de congrés
Accés obertThis paper proposes a new and explicitly frequencyadaptive method for Virtual Flux estimation and voltage sensorless grid synchronization under unbalanced conditions. The proposed system is based on using Second Order ... -
Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters
Suul, Jon Are; D'Arco, Salvatore; Rodríguez Cortés, Pedro; Molinas Cabrera, Marta (2016-05-12)
Article
Accés obertThis paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference ... -
Power control of VSC HVDC converters for limiting the influence of ac unbalanced faults on multi-terminal DC grids
Suul, Jon Are; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro (2010)
Text en actes de congrés
Accés restringit per política de l'editorialIt will be important for the operation of future multi-terminal HVDC systems that each converter unit is capable of limiting the influence of nearby AC faults on the DC grid. Thus, the local control systems at each terminal ... -
Voltage-sensor-less synchronization to unbalanced grids by frequency-adaptive virtual flux estimation
Suul, Jon Are; Luna Alloza, Álvaro; Rodríguez Cortés, Pedro; Undeland, Tore (IEEE Press. Institute of Electrical and Electronics Engineers, 2012-07)
Article
Accés restringit per política de l'editorialThis paper proposes a simple method for inherently frequency-adaptive virtual flux (VF) estimation intended for voltage-sensor-less grid synchronization and control of voltage source converters. The frequency-adaptive ...
