Multicommodity network flow model for long-term hydro-generation optimization

A model for long-term hydrogeneration optimization based on multicommodity network flows is presented. The problem of optimizing hydrogeneration with partially dependent water inflows in the reservoir systems is also addressed. The results obtained are consistent with the operating experience for the reservoir systems and meet expectations. The optimal results obtained for volume and discharge for one of the reservoirs is shown graphically. The same type of result can be obtained for any of the reservoirs. These graphs show that water use policies are specific for each commodity; thus it is worth optimizing simultaneously the different types of water use with common constraints in a single program as the model proposes.<
