Ensuring stability in the age of renewable energies
(2016, 60 pages, 15 Figures, 1 Tables, ISBN: 978-3-8047-3549-1)
So-called flexibility technologies are necessary to balance the fluctuations naturally inherent to power generation from wind and photovoltaics. The various viable options include flexibly dispatchable power plants as well as storage systems or the balancing of power demand and power feed-in (demand-side management). The challenge is to identify the options combining stability, sustainability, cost efficiency and social acceptability.
A working group of the Academies’ Project "Energy Systems of the Future" (ESYS) has developed a special model enabling the comparison of 130 different constellations. The position paper published by acatech, the National Academy of Sciences Leopoldina and the Union of the German Academies of Sciences and Humanities summarises the main findings and presents design options for energy policies.
