ABSTRACT
This paper describes a hybrid optimization method for finding the optimal operating policy of a reservoir system with water energy utilization. A hydropower plant, in turn, can use its reservoir storage to turbine free water for energy production, thus avoiding fuel expenses with thermal units. The well-timed allocation of hydro energy resource is a complication task, because if water is used in the present period, it will not be available in the future. This hydrothermal coordination problem is solved by peak shaving method using the proposed hybrid optimization method. It combines the genetic algorithms with the traditional numerical optimization method. The proposed hybrid method has been applied on a real hydrothermal system, the Slovak power system.

Keywords: Hydro plant, hydrothermal coordination problem, peak shaving method, genetic algorithms, hybrid optimization
