Hydrothermal scheduling is a relevant stage of operation planning, whose objective is to minimize the total cost of operation, together with respecting the restrictions of electrical systems such as transmission losses and the power balance throughout of the demand horizon. In recent years there has been an increase in interest in the implementation of pumped-storage hydroplants in electrical systems in order to operate in conjunction with intermittent sources. With this new paradigm, the problem of hydrothermal scheduling has become more complex. This paper aims to apply the dynamic programming technique to solve the hydrothermal scheduling problem with the inclusion of pumped-storage hydroplants. The procedure is applied to an equivalent test system, and it is possible to obtain a lower cost in relation to the base case together with the established restrictions.
