Abstract

Higher penetration of distributed generation units (DG) into the distribution network (DN) has imminent influence on DN’s power quality and system losses. With DG units being properly placed and sized, numerous positive effects on DN can be achieved. This paper focuses specifically on influence of active and reactive power generation from photovoltaic (PV) systems on voltage profiles and power losses in DN. Main goal of the paper is to evaluate, if power injections from installed PV systems can contribute to the power loss reduction. A case study on realistic model of medium voltage part of DN in town Maribor has been performed. Sizing and suitable location for PV systems that can be installed in the future has been obtained by assessment of buildings’ roof photovoltaic potential. The results presented in the paper show that proper power injections can help reducing power losses in the discussed DN.
