Abstract
Advanced control techniques including Volt-Watt and Volt-VAR have been developed for high penetration integration of photovoltaic (PV) inverters. These techniques typically focus on voltage regulation as measured at the Point of Common Coupling (PCC). Designing advanced control functions is challenging in applications with distributed inverters not installed at the PCC due to the voltage rise in the low voltage network. This work proposes a method for control for distributed microinverters by utilizing readily available data. It is shown that this approach could reduce unnecessary PV microinverter tripping and power curtailment while supporting voltage control schemes as measured at the PCC. Test results are provided from simulation-only scenarios and a Power-Hardware-In-The-Loop (PHIL) test platform.
