Machine concept optimization for pumped-storage plants through combined dispatch simulation for wholesale and reserve markets / Klaus Engels in La Houille blanche, N° 3 (Juin 2012) 

Public ISBD [article]  in La Houille blanche > N° 3 (Juin 2012) . - pp. 37-43 Titre : Machine concept optimization for pumped-storage plants through combined dispatch simulation for wholesale and reserve markets Type de document : texte imprimé Auteurs : Klaus Engels, Auteur ; Michaela Harasta, Auteur ; Werner Braitsch, Auteur Année de publication : 2012 Article en page(s) : pp. 37-43 Note générale : Hydraulique Langues : Anglais (eng) Mots-clés : Pumped-storage  plant  Combined  wholesale  market  Reserve  market  Simulation  Optimized  dispatch  Machine  concept  Portfolio  effect  Plant  flexibility  Economic  evaluation  Investment  decision 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.
