An evolution strategy for shore-term operation planning of hydrothermal power systems

This paper reports on a new approach to solve the short-term operation plan ning problem of hydrothermal power systems. It uses evolution strategies to determine the optimal schedules of all hydroelectric and thermal power pla nts in a closed optimization. A decomposition of the optimization problem i s not necessary. Numerical experiments show, that the proposed method is ab le to solve the complex non-linear optimization problem with its wealth of constraints in acceptable computation time.
