After almost two decades of research, Vijay Vittal, a Fulton Schools professor of power systems engineering, has helped overcome a major challenge in his field by discovering ways to reliably integrate renewable resources into conventional electrical power grids. The news publication of the Institute of Electrical and Electronics Engineers reports on Vittal’s progress in maintaining power grid stability in ways that enable the use of renewable energy sources such as photovoltaic solar systems. Along with related advances by colleagues in power electronics, Vittal is contributing to efforts to incorporate renewable energy sources into existing power infrastructure without disrupting grid operations.
