This study presents the modelling and simulation of a single area power system network containing three different generating sources, solar thermal power plant (STPP), thermal, and diesel power plants. The simultaneous frequency and voltage control problem has been investigated using Linear Quadratic Regulator (LQR) and State Feedback based Sliding Mode Control (SF-SMC) design. Also, the integration of Particle Swarm Optimization (PSO) has been considered for the selection of LQR cost function weight matrices and SMC control parameters. Proper selection of LQR and SF-SMC parameters allows the controllers to handle the complexities involved in a very efficient manner and also augments necessary robustness in the controller design. The transient performance of the PSO based LQR and SF-SMC controlled system has been assessed in terms of time-domain performance indices, and it has been compared with the conventional PID and 2-DOF PID controllers. Additionally, the robustness of the proposed controllers has been tested and verified after contemplating variation in model parameters.
