Multi-area interconnected automatic generation control with IPFC and TDOFPID controller

Present work introduces a most popular evolution based algorithm and applied in two degree of freedom proportional integral Derivative (TDOFPID) Controller based multi area power system. Differential Evolution (DE) optimization technique is applied here to tune the TDOFPID gains. In each area of system consists of Automatic generation control with addition of non-linarites. In this model time delay, Generation rate constraints (GRC) and reheat turbine is added to make non-linearity. At first attempt simulation is being done in two area with DE optimistion technique. Next attempt a series connected Flexible Alternating Current Transmission (FACT) device such as Interline Power Flow Control (IPFC) is included into the system and simulated. DE is also used to get the optimum value of TDOFPID controller having Integral time absolute error (ITAE) has been the objective function. At last robustness analysis is done with varying parameter and different loading conditions. It is seen that, TDOFPID with IPFC gives better response compared to others.
