| dc.description.abstract | Automatic generation control (AGC) plays a crucial role in the operation and control of power systems. AGC is a supportive scheme that maintains the system frequency under permissible limits. This thesis presents Automatic Generation Control (AGC) of a three unequal area thermal system incorporating solar thermal power plant (STPP) in area-1 and geothermal power plant (GTPP) in area-2. The control areas are provided with single reheat turbine and generation rate constraints (GRC) of 3% / min. A maiden attempt has been made to apply a Proportional derivative–Tilt integral derivative (PD–TID) cascade controller in AGC. Controller gains are optimized using Coyote optimization algorithm (COA) which is population based metaheuristic. The system dynamic performances are studied with 1% step load perturbation in Area1. Performance of classical controllers such as Proportional Integral (PI), Proportional Integral Derivative (PID), Tilt Integral Derivative (TID) controllers are investigated and compared with PD–TID cascade controller. Investigations reveal that PI, PID and TID provide more or less same response where as PD–TID cascade controller provides much better response than the later. Dynamic analysis has also been carried out for the controllers in presence of random load pattern, which reveals the superior performance of the PD–TID cascade controller. Sensitivity analysis reveals that the COA optimized PD–TID Cascade controller parameters obtained at nominal condition of loading, size and position of disturbance and system parameter (Inertia constant, H) are robust and need not to be reset with wide changes in system loading, size, position of disturbance and system parameters. | |
