Abstract: This paper presents the method to design the robust controller for the hydro thermal system considering interconnection of two areas. The feasibility of using the automatic generation control with energy capacitor system is implemented to both areas. Wind turbines are considered to be one of the most used alternative sources of energy to solve global warming worldwide. The output of wind turbines depends on the weather condition which causes large fluctuation in the power output when WTs connect to the system. So, the system should be capable of handling uncertainties caused by the wind turbines and load variations. H∞ loop-shaping method is designed as the proposed controller which is used to regulate and improve system stability in the hydro thermal power system. Results demonstrate that the hydro thermal system with CS-based H∞-controller gives higher system stability and more robustness than the hydro thermal system with ECS-based PID controller.
