Green Power Zone

Abstract

This paper presents the concept, prospect and operation of Green Power Zone (GPZ). The GPZ is defined as part of power grid which provides electrical energy with varying quality depends on customer requirement. Different power quality levels in the premium zone can rang from better than normal utility supply to a supply close to an ideal situation. Electrical energy to the zone is supplied through two feeders from two independent substations. The GPZ center is fully equipped with custom power devices, namely dynamic voltage restorer (DVR) and distribution static compensator (DSTATCOM) or even unified power quality conditioner (UPQC). The GPZ can also contain a distributed generator (DG) to take care the power interruption situations from the utility. The incoming feeders to the zone can be designed with improved grounding, insulation, arresters and reclosing. The simulation results are shown the performance of GPZ by using digital computer simulation program.
