Abstract :Short-term hydrothermal coordination problems (STHCP) include power systems with thermal and hydraulic production units. Suppose the reservoirs of the hydraulic production units in the system are vast. In that case, it is assumed that the water in the reservoirs stays mostly the same during the operation period. Short-term hydrothermal coordination problems with hydraulic production units having this feature are called constant-head STHCP. Constant-head STHCP includes both electrical and hydraulic constraints. Variables such as the amount of water entering and leaving the reservoir of each hydraulic production unit, the reservoir capacity, and the amount of water stored in the reservoir are known as hydraulic constraints. The average differential evolution (ADE) algorithm, one of the newly developed meta-heuristic algorithms, is applied to solve the STHCP with a fixed head. Transmission line losses of the power system are calculated using the Newton-Raphson load flow method. In this study, the lossy STHCP with fixed head is solved for two cases where the input and output characteristics of the thermal generation units have both convex and non-convex characteristics. The results obtained from the solutions to both cases\\\' problems are discussed.
