New Method Monitors Grid Stability With Hydropower Project Signals

Scientists at Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have developed an algorithm to predict electric grid stability using signals from pumped storage hydropower projects. The method provides critical situational awareness as the grid increasingly shifts to intermittent renewable power. Hydropower is a renewable energy source directly … [continued]
