Master-slave design for frequency regulation in hybrid power system under complex environment

The advancement in technology has proceeded exceptionally that the stability of the power system becomes a major challenge. The mismatch of generation and demand creates frequency perturbation that need to be curbed under the limits to avoid power breakdown. Owing to this, the paper focuses to counter the ever-increasing challenges to the power system much like load and fault disruption that causes frequency deterioration and breakdown. A novel master-slave (MS) control design is formulated for a hybrid interconnected power system in which fractional-order-proportional-integral-derivative (FOPID) controller act as a master and model predictive controller (MPC) act as a slave controller. The gain parameters of the master controller are tuned by salp swarm algorithm (SSA) which act as a secondary loop controller, while slave act as a primary loop controller. The MS formation has resultantly removed the steady-state error associated with MPC and help to mitigate the LFC problem. Furthermore, the superiority of the controller is tested under load and fault disruption in a multi-area power system. The designed controller is tested under four states (1) abrupt load variation, (2) sinusoidal load deviation, (3) sensitivity analysis and (4) IEEE 39-bus test system analysis. The disclosed simulation results depicts that the proposed control scheme has a dynamic performance as compared to other controllers.
