Test Cases for a Coupled Power-Plant and Geostorage Model to Simulate Compressed air Energy Storage in Geological Porous Media Wolf Tilmann Pfeiffer, Francesco Witte, Ilja Tuschy, Sebastian Bauer

Abstract

CAES using porous geological formations such as sandstones could provide the large storage capacities required in future energy systems largely based on renewable sources. In such systems storage pressure, achievable mass flow and power output have strong interdependencies. Thus, an integrated assessment of the power plant and the geostorage is required, for which a coupling approach is presented. Three generic test cases are constructed, demonstrating an accurate representation during all operational modes.
