Abstract :
This paper presents a nonuniform composite representation of hydroelectric systems for use in long-term hydrothermal scheduling. This representation was developed from reservoir operational rules based on optimal reservoir trajectories obtained with a deterministic hydrothermal scheduling algorithm. A test system consisting of 7 large hydroelectric plants of the Southeast Brazilian Power System with 12572 MW of installed power capacity was selected for a case study. Operational cost comparisons with the classical uniform composite representation reveal significant savings
