A high-performance voltage sag detection algorithm for a dynamic voltage restorer
Roldan Perez, Javier; García Cerrada, Aurelio; Ochoa Giménez, Miguel; Zamora Macho, Juan LuisDynamic Voltage Restorers (DVRs) are a costeffective solution to protect sensitive loads against voltage sags in medium- and high-power applications because the power required to compensate sags is only a fraction of the ... -

Discrete repetitive controller with a non-integer number of samples per cycle
Roldan Perez, Javier; García Cerrada, Aurelio; Zamora Macho, Juan LuisRepetitive controllers are used to track periodic references or to reject periodic disturbances exactly. This letter presents a simple addition for a discrete repetitive controller to tackle applications in which the period ... -
Discrete repetitive controller with a non-integer number of samples per cycle and its application to an active power filter
Roldan Perez, Javier; García Cerrada, Aurelio; Zamora Macho, Juan LuisRepetitive 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 ... -
Diseño de reguladores resonantes en tiempo discreto para un restaurador dinámico de tensión
Roldan Perez, Javier; Rodríguez Cabero, Alberto; Ochoa Giménez, Miguel; García Cerrada, Aurelio; Zamora Macho, Juan LuisLa calidad de la potencia se ha convertido en una temática muy relevante en los sistemas eléctricos de potencia debido al número creciente de cargas sensibles, así como de fuentes generadoras de armónicos. En este escenario, ... -

The effect of wind generation and weekday on Spanish electricity spot price forecasting
Cruz García, Alberto Miguel; Muñoz San Roque, Antonio; Zamora Macho, Juan Luis; Espínola Vílchez, RosaThis paper empirically compares the predictive accuracy of a set of methods for day-ahead spot price forecasting in the Spanish electricity market. The methods come from time series analysis and artificial intelligence ... -
Wind generation in weak systems
Rouco Rodríguez, Luis; Zamora Macho, Juan Luis; García Cerrada, AurelioControl systems of wind generators are usually designed neglecting the effect of the external grid (the impedance of the grid is much smaller than the impedance of the step-up transformers). Wind generator manufacturers ...
