Backup flexibility classes in complex renewable energy networks — •David Schlachtberger1, Sarah Becker1, Stefan Schramm1, and Martin Greiner2 — 1Frankfurt Institute for Advanced Studies, Uni Frankfurt, Frankfurt am Main, Germany — 2Department of Engineering, Aarhus University, Aarhus, Denmark
How large will be the demand for more flexible backup plants in an European power system with an increasing share of fluctuating renewable energies? We use eight years of high resolution weather-based wind and solar power generation data to split the backup systems required to cover the residual load into three flexibility classes for daily, weekly, and seasonal time-scales. They are distinguished by the maximum rates of change of their power output. We find that a large fraction of seasonally and weekly flexible backup systems can no longer be reasonably integrated above a penetration of renewables of around 50% and 90% of the mean load, respectively. We also find that the total required backup capacity can only be reduced if countries share their excess generation and backup power.
