Load frequency controller design for two area interconnected power system with DFIG based wind turbine via ant colony algorithm

In this research, ant colony algorithm for proportional plus integral (PI) optimal tuning to design load frequency controllers is introduced. A mathematical model of a network with DFIG based wind turbine in two area frequency control is developed. Time domain simulations of the various interconnected power system areas subjected to major disturbances are investigated. A method to enhance the system frequency performance based on ant colony optimization for various wind energy penetration scenarios is presented. Simulated results show that the ant colony controller has a significant capability to enhance the frequency performance.
