Abstract: The unit commitment problem in a power generation system
comprising thermal and pumped-storage hydro units is
adressed. A large-scale mixed-integer optimization model
for unit commitment in a real power system is developed
and solved by primal and dual approaches. Both solution
methods employ state-of-the-art algorithms and software.
Results of test runs are reported.
