Hydro power is a renewable source of energy that plays a key role in electric power systems, especially due to its flexibility and to its ability to allow the integration of other intermittent renewable sources. The medium-term hydro-scheduling is a very complex task that involves a great variety of processes and variables, some of which are considered stochastic, because of their uncertainty in the medium term. Two combined methods are used by Iberdrola in medium-term hydro-scheduling: stochastic optimization and simulation. This paper briefly describes these processes and shows two examples of applications to hydro management. One is referred to the continuous task of scheduling, and the other is an example of maintenance planning. Nevertheless these models have also been used for designing and upgrading of hydropower plants, international river agreements, analysis of ecological flows, etc.
