NREL, Duke Energy Explore Smart Inverters for Grid Stability
NREL is working with Duke Energy and Alstom Grid to explore ways that smart inverters can increase grid stability. Using data from Duke Energy, NREL is validating the voltage control capabilities of smart inverters in modeled, real-world scenarios.
Adding renewable energy sources such as solar to a utility's existing distribution systems can introduce much faster power dynamics and potentially stress voltage control devices to the point of premature failure. Smart inverters—devices that convert direct current solar power into alternating current power for the grid—have features that could be used to help control voltage and make the grid more stable.
