Wind Power Variability

Variability of power production is a major issue in wind generated electricity.

Methods for Regulating Wind Power's VariabilityUnder Development by Electrical Engineer

October 16, 2007

AUSTIN, Texas—As Texas' electric grid operator prepares to add power lines for carrying future wind-generated energy, an electrical engineer at The University of Texas at Austin is developing improved methods for determining the extent to which power from a wind farm can displace a conventional power plant, and how best to regulate varying wind power.

"The cost of wind energy has become competitive with that of energy from fossil fuels because of technology improvements," said Assistant Professor Surya Santoso. "Unfortunately, electric power generated from wind energy is intermittent and variable. That means we need to have better measurements of wind power plants' output as we integrate wind energy into existing power systems. We also need to develop a way of managing wind power so it can be more readily called upon when needed."
