Short Term Hydrothermal Coordination Using Multi-Pass Dynamic Programming

on/off operation of thermal units. The PSM is always superior to the CEM on computational efficiency. The computation time of PSM does not significantly vary for different situations. The computation efficiency and its consistency are therefore two advantages for the PSM. The application of the PSM to coordinate hydro and thermal subsystems is simple and straight forward; thus, more effort can be devoted to the detailed modelling of the hydro sub-system, such as backwater curves, flood curves, tail-water curves, etc.
