Battery Sizing and Location for Provision of Network Support Services
Jankovic, Njegos; Nogales Balderrama, Marcelo; Roldan Perez, Javier; Prodanovic, Milan -
DFT-based controller for sag and harmonic mitigation with a series-connected compensator
Roldan Perez, Javier; Zamora Macho, Juan Luis; García Cerrada, Aurelio (European Association for the Development of Renewable Energies, Environment and Power Quality (EA4EP (Santiago de Compostela, España), 2012-03-28)Voltage-quality problems in power distribution networks include harmonics, voltage sags and swells and unbalances. These problems may seriously affect sensitive industrial loads causing production interruption or equipment ... -
Enabling the Seamless Coordination and Synchronization of Microgrids using Batteries
Morán Río, Diana Patricia; Roldan Perez, Javier; Prodanovic, Milan; García Cerrada, AurelioLas microrredes se han convertido en una alternativa común para integrar fuentes de energía renovables en redes de distribución Estas redes están formadas por una variedad de recursos renovables y almacenamiento, que pueden ... -
Finite-gain-current repetitive controller for synchronverters with harmonic-sharing capabilities
Roldan Perez, Javier; Prodanovic, Milan; Rodríguez Cabero, Alberto; Guerrero, Josep M.; García Cerrada, Aurelio (Institute of Electrical and Electronics Engineers; Institute of Electrical and Electronics Engineers (Ljubljana, Eslovenia), 13/05/2018)Power electronics interfaces are commonly used for renewable energy integration in microgrids and their control as synchronverters represents an alternative to typical control configurations. This control technique introduces ... -
Improving the accuracy of a discrete repetitive controller applied to an active power filter when the mains frequency is unknown
Roldan Perez, Javier; García Cerrada, Aurelio; Zamora Macho, Juan Luis (Universidad de País Vasco (Bilbao, España), 2010-07-07)Repetitive controllers are used to track periodic references or to reject periodic disturbances, exactly. When implementing this type of controllers digitally, the sampling period has to be chosen so that there is an integer ... -
Modeling and sensitivity analysis of consensus algorithm based distributed hierarchical control for DC microgrids
Meng, Lexuan; Dragicevic, Tomislav; Vasquez, Juan Carlos; Guerrero, Josep M.; Roldan Perez, Javier (Sin editorial (Charlotte, Estados Unidos de América), 15/03/2015)Distributed control methods for microgrid systems become a popular topic in recent years. Distributed algorithms, such as consensus algorithms, can be applied for distributed information sharing. However, by using this ... -
Periodic and non-periodic disturbance rejection techniques for an advanced Dynamic Voltage Restorer
Roldan Perez, Javier; García Cerrada, Aurelio; Zamora Macho, Juan Luis; Roncero Sánchez-Elipe, Pedro Luis; Acha, Enrique (PE&ES: Sistemas Eléctricos y Electrónicos de Potencia; GTE: Grupo de Tecnología Electrónica; GISS: G (Badajoz, España), 2011-07-05)Voltage sags and swells, voltage harmonics and voltage imbalances in power systems may affect sensitive loads causing production interruption or equipment damage. Now-adays series voltage compensation using power electronics ... -
Phase-matched frequency adaptive repetitive controller for a grid-supporting STATCOM
Roldan Perez, Javier; García Cerrada, Aurelio; Rodríguez Cabero, Alberto; Prodanovic, Milan (Power Electronics and Motion Control Council (Budapest, Hungría), 26/08/2018)STATCOMs are widely used to provide voltage support in electrical distribution systems. However, if the grid voltage is distorted, the output current of a STATCOM may also be distorted unless a harmonic current controller ...
