Optimale Blockauswahl bei der Kraftwerkseinsatzplanung

The paper addresses the unit commitment problem in power plant operation planning. For a real power system comprising coal and gas red thermal as well as pumped storage hydro plants a large-scale mixed integer optimization model for unit commitment is developed. Then primal and dual approaches to solving the optimization problem are presented and results of test runs are reported.
