This study focuses on modelling of two area hydro-thermal interconnected system integrated with wind, Small Hydro Plant (SHP) and Solar Thermal Plant (STP). Flexible AC Transmission (FACT) device named as Static Synchronous Series Compensator (SSSC) and an energy storing element called Super Magnetic Energy Storage (SMES) unit is incorporated in the model. To control and monitor the system, an effective Particle Swarm Optimization (PSO) optimized multistage controller is proposed. The effectiveness of the suggested controller is verified under diverse step and time varying load perturbation. The superiority of controlling action of the proposed controller is also proved to be efficient than other prominent controllers. System stability is analyzed and found to be stable through the establishment of Eigen value analysis and bode plot. Furthermore, the system behavior is studied with various combination of SSSC and SMES in different area simultaneously. To make the analysis more realistic, appropriate time delay is included in the proposed study. Finally, sensitivity analysis of the network by varying the different system parameters, governed through a multistage controller is carried out.
