The results are based on a MATLAB/Simulink model of a pump system, which is explained and verified. To analyse the energy demand and time for filling processes and to examine the applicability of the self-tuning strategy three possible systems and different filling strategies are regarded. Based on the most efficient strategy a self-tuning program was developed. For this program, convenient starting conditions and target values for constant or variable outflow are described. Thus, this optimisation strategy can be used as an on-line tuning program, which is simple to implement in running pump storage systems. The tuning strategy is tested with a genetic algorithm and a Nelder-Mead algorithm. Finally, a self-tuning program for fixed time operation mode is shown. ER -
