This paper presents a suboptimal optimization method for solving the annual hydrothermal scheduling problem for a multireservoir hydrothermal system. Hydrothermal scheduling is performed in order to find the optimum cost of a mixed hydrothermal system is minimized. In this paper the hydrothermal scheduling problem is formulated as a constrained optimization problem which is decomposed into three subproblems: maintenance scheduling of thermal units, dispatch of thermal units and dispatch of hydroplants. The algorithm takes into consideration the stochastic nature of the water inflows to the reservoirs and the forced outage rates of the thermal units. Results from a study case are reported.
