The method involves increasing or reducing portion based on solar-thermal heating over a short time period to provide a positive or negative reserve power. Another portion based on fuel-operated heating is slowly increased or reduced and the latter portion based on solar-thermal heating is correspondingly reduced or increased again. The latter portion based on thermal heating is increased or reduced by focusing or defocusing of solar collectors, by increased or reduced throughput of a solar-thermally heated carrier fluid, and/or by emptying or filling a repository contains the fluid. |
