The increasing integration of distributed energy resources (DERs) into distribution grids can pose challenges to power quality. Specifically, distributed photovoltaic (PV) systems can cause issues, such as voltage fluctuations, due to their intermittent nature. PV inverter control deployment is necessary to minimize these issues. The existing local inverter control methods might not adequately address the broader grid concerns. As such, this work proposes an optimization-based volt-varwatt centralized control method to optimize the output of PV across the grid and solve the voltage issues with high levels of PV integration. The proposed methodology is validated on a medium IEEE 123-bus and a large 3,989-bus distribution network. Simulation results show significant improvement in the overall voltage profiles, and thus, the proposed method proves to be effective in enhancing the overall system performance.
