Optimization process of a multi-reservoir system in a market context

This paper presents the process used by ENEL in order to optimize the tasks of scheduling, controlling and operating of multi-reservoir systems within the Italian energy market. The process described below is divided in three steps: definition of the constraints, real time operation and real time actuation. On the whole, the process covers a timeframe that begins up to 14 days before the day of delivery and ends with real-time actuation. Each step is characterized by a proper optimization process with different description of the objective function, constraints and with a different focus on the time horizon to be evaluated.
