Standard models are created to carry out power system dynamic studies. One of the major problems in this regard is the parameter identification of these models. These parameters are not constant and may change due to extensive use and the large number of repairs, modifications and overhaul of the units, and, consequently, they cannot provide a
In general, the HTGS regulates hydro-turbine speed to provide stable power to the grid without considering shaft vibration. Nevertheless, the shaft system model controls the vibration performance instead of the speed. In fact, HTGS and the shaft system model interact with each other. Unfortunately, related studies on the unified model have been
