| Résumé : |
In Germany’s energy markets of today, pumped-storage power plants offer excellent business opportunities due to their outstanding flexibility. However, the energy-economic simulation of pumped-storage plants, which is necessary to base the investment decision on a sound business case, is a highly complex matter since the plant’s capacity must be optimized in a given plant portfolio and between two relevant markets : the scheduled wholesale and the reserve market. This mathematical optimization problem becomes even more complex when the question is raised as to which type of machine should be used for a pumped-storage new build option.
For the first time, it has been proven possible to simulate the optimum dispatch of different pumped-storage machine concepts within two relevant markets – the scheduled wholesale and the reserve market – thereby greatly supporting the investment decision process. The methodology and findings of a cooperation study between E.ON and RWTH Aachen University in respect of the German pumped-storage extension project “Waldeck 2+” are described, showing the latest development in dispatch simulation for generation portfolios. |
