Teaching-learning based optimization algorithm based fuzzy-PID controller for automatic generation control of multi-area power system

- Fuzzy-PID controller is proposed for AGC of multi-area power system.
- TLBO algorithm is applied to optimize the parameters of fuzzy-PID controller.
- The superiority of proposed approach over LCOA, GA, PS and SA based PID controller is shown.
- Robustness analysis is performed under wide changes in system parameters and disturbance.
