Title

Intermittent structure of wind power fluctuations

Speaker

Dr. Samy Lakhal (Okinawa Institute of Science and Technology)

Abstract

Renewable energies fluctuate due to the variability of their sources. For wind energy, atmospheric turbulence produces extreme power fluctuations, straining electrical infrastructures. A better understanding of these intermittent properties is a first essential step in the design and optimization of next-generation renewable systems. I will introduce the concept of statistical intermittency from basic construction steps. I will then describe the correlation structure of wind power productions, here using the data sampled from a Texas wind farm of 80 turbines. We find that extreme power events are spatially correlated, leading to the persistence of non-Gaussian fluctuations at the entire farm scale.
