They also serve as the basis for illustrating the negative impact of electrical disturbances on components and for assessing compliance with the required standards and recommendations within a regulating framework. Within these pages lies a comprehensive overview of both the traditional PQ indices in use today and new indices likely to be used in the future. Key features of this book include:a special focus on the metrics for quantifying PQ disturbances;a complete review of methods and indicElectric power systemsQuality controlElectric power system stabilityMeasurementElectric power failuresEconomic aspectsElectric utilitiesElectric power systemsQuality control.Electric power system stabilityMeasurement.Electric power failuresEconomic aspects.Electric utilities.333.793/2333.7932621.312Caramia Pierluigi319435Carpinelli Guido8200Verde Paola1966-319436MiAaPQMiAaPQMiAaPQBOOK9910841155403321Power quality indices in liberalized markets778742UNINA
