A challenge in grid planning and operation is the identification of optimal Volt-VAR settings in combination with existing voltage regulation schemes applied by the utility. This paper features a technical assessment of smart inverter Volt-VAR settings in combination with an advanced load tap changer control. Quasi-Static Time Series (QSTS) simulation using the IEEE 13 node test feeder and different distributed PV penetration scenarios is carried out. The results show a clear trend for optimal Volt-VAR settings for the different PV penetration scenarios.ensmart invertervolt / var controlphotovoltaic (PV) systemload tap changer controlDIgSILENT Powerfactoryconference paper
