Abstract

This article addresses two main issues concerning the maximum loading point in three-phase distribution systems. Initially, a tool was developed using OpenDSS to generate PV curves tailored to the reality of unbalanced distribution systems. Subsequently, the impact of Volt/Var control implemented by smart inverters was investigated in photovoltaic systems connected to the network. The results demonstrate significant improvements in the voltage profile and an increase of about 17.6% in the maximum loading point for a 34 nodes network, highlighting the efficiency of reactive power injection controlled by voltage in photovoltaic systems.
