Yong Liu, research assistant professor of electrical engineering and computer science at UT, is researching problems inherent to current photovoltaic power generation, its effect on the US power grid frequency stability, and how to mitigate its effect in order to avoid large blackouts.

Photovoltaic power, or PV power, converts solar energy to electricity without burning fossil fuels and is considered the carbon-free solution for our energy problem. While the best-known example is the standard solar panel that has been around for decades, breakthroughs in technology have provided reduced cost as well as increased efficiency, which in turn greatly increases the potential capacity of PV plants.
