Modelling and Optimization of Hydrothermal Generation Scheduling

An approach is proposed to optimize the operation of energy production systems over middle term planning periods. Randomness of primary load is explicitly considered. A precise model is used to represent the hydraulic system (with individualized reservoir in cascade, water transportation delays, nonlinear generation, ...) as well as the non-hydraulic system (thermal generations, interchanges, load shedding, ...). Difficulties resulting from the large scale are overcome by decomposition techniques.
