ABSTRACT: The paper presents a new long-term, large-scale hydrothermal
production scheduling method. The proposed method uses both composite
hydro and composite thermal representations, based on the monthly or
weekly energy requirement. The method can minimise the thermal
production cost and maximise the hydro production profit. The advantage
of this method is that it uses a more precise cost objective function
considering unit commitment effect. The method can be used by the owners
of independent hydro plants in a region for long-term hydroelectric
scheduling under both deregulation and competition. A case study shows
that the model allocates successfully and efficiently the hydroelectric
resources to the peak demand periods with negligible computation time
