A novel hybrid gravitational search and pattern search algorithm for load frequency control of nonlinear power system
Selection of objective function and controller structure is vital for controller design. An objective function using ITAE, damping ratio and settling times is proposed. The concept is applied to design an hGSA-PS-based PI/PID controller for LFC. Nonlinear interconnected power system model with GRC, GDB and time delay is considered.
