Short time fluctuations of renewable energies — •Joachim Peinke, M. Reza Rahimi Tabar, Patrick Milan, and Matthias Wächter — Institut für Physik und ForWind, Universität Oldenburg, Germany

Wind and solar energy, the main renewable energies on which the modern sustainable electrical power supply will be based, are characterized by a high volatility. News report frequently on a new challenge for the energy management to handle these new sources. For a better understanding of their impact on the electrical power system it is essential to know in more details the nature of the power fluctuations of wind and solar energy.

In our contribution we present results from an analysis of wind and solar power. We show that the turbulent features of the weather can be seen in the power output of such systems. We will mainly focus on the characterization and modeling of these power systems with advanced stochastic tools. Concerning the extreme event statistics, we show evidence that solar power is more volatile than wind power.
