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 indic 606 $aElectric power systems$xQuality control 606 $aElectric power system stability$xMeasurement 606 $aElectric power failures$xEconomic aspects 606 $aElectric utilities 615 0$aElectric power systems$xQuality control. 615 0$aElectric power system stability$xMeasurement. 615 0$aElectric power failures$xEconomic aspects. 615 0$aElectric utilities. 676 $a333.793/2 676 $a333.7932 676 $a621.312 700 $aCaramia$b Pierluigi$0319435 701 $aCarpinelli$b Guido$08200 701 $aVerde$b Paola$f1966-$0319436 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830882803321 996 $aPower quality indices in liberalized markets$9778742 997 $aUNINA
