Abstract
This paper describes a methodology for coordinating the mid and short-term scheduling of hydrothermal systems. The technique is able to translate the electrical problems at the short-term level into a constraint to be added to the mid-term scheduling problem. This constraint, called a Benders cut, only refers to weekly target variables in the mid-term problem. The Benders decomposition therefore allows a feedback between the short-and mid-term models with only a few modifications required in the specialized algorithms used at each level. A case study with the Brazilian Southeast Network is presented and discussed.
