Custom power: Optimizing distribution services

Abstract

Power disturbances that once would barely have been noticed may now produce costly malfunctions in critical customer equipment. Fortunately, a new generation of power electronic controllers is becoming available for use on distribution systems, which will enable utilities to provide premium-quality electricity to customers with sensitive loads. The first of these controllers, called Custom Power devices, are now entering utility service, providing a cost effective alternative to the power-conditioning equipment previously installed on customers` premises. Eventually, the integration of Custom Power controllers with distribution automation equipment will help create distribution systems that are optimized from both the utility`s and the customer`s point of view.
