Abstract

Voltage Unbalance and voltage rise are power quality concerns for low voltage residential distribution networks due to the random location and rating of single-phase rooftop photovoltaic cells. In this paper, application of series (DVR) and parallel (DSTATCOM) custom power devices are investigated to mitigate these problems. Load flow analysis is first carried out to investigate the effects of rooftop PVs on network voltage profile. Then the effectiveness, locations and ratings of these two custom power devices are compared for urban and semi-urban networks through load flow analysis. Finally the efficacy and applicability of these devices are verified through PSCAD/EMTDC simulations.
