Large generation facilities turning coal, gas, and water into electricity have been the mainstay of the electric power system for decades. They produced a steady flow of power—24/7. But as more, smaller intermittent generators, like wind turbines, and solar panels are added to the system, that predictability diminishes. In this episode, Purdue University Professor Dr. Steve Pekarek joins Dave Whitehead for a discussion about how this challenge is driving new methods of power system control.
