NREL Study Finds Integrated Utility Control Can Improve Grid Voltage Regulation Beyond Advanced Inverters Alone

As demonstrated in a recent study by NREL, General Electric (GE) Grid Solutions, and Duke Energy, when a large solar photovoltaic (PV) system is connected to the electric grid, a utility’s centralized control system can regulate the voltages on the grid’s distribution feeder lines better than advanced inverters alone. Researchers found that coordinated voltage control can complement advanced inverters and manage cost-effective integration of high PV penetrations on the local distribution system. This study was one of two NREL publications that made the Advanced Energy Economy short list of essential articles that demonstrate the value and benefits of distributed energy resources.
