Abstract

Coordination of operation of hydrothermal power systems is in line with optimum reduction of energy generation costs. Researches for preparation of operational models for planning of hydrothermal power systems have been started since 50 years ago. HTCOM software package as one of these models was developed in 1997 in McMaster University, Canada. This model determines long - term operational policies for a hydrothermal power system with multi-purpose reservoirs. This nonlinear model considers stochastic inflows by scenario analysis. However, energy demand is considered deterministic. Considering capabilities of this model in dealing with hydrothermal planning and to improve its performance, uncertain energy demand is applied to this model in this paper. The improved model has been utilized in a real world system in the Khuzestan province in Iran, comprising of multi-purpose reservoirs and thermal power plants.
