Deregulated Multiarea AGC Scheme Using BBBC-FOPID Controller

摘要

In this paper, a fractional-order proportional-integral-derivative (FOPID) controller for automatic generation control (AGC) scheme has been designed utilizing the big bang-big crunch algorithm. An AGC scheme in a deregulated electricity market environment has been developed. The objective was to compute optimal FOPID controller parameters so that on a load perturbation generator can regulate power, to achieve the best dynamic response of frequency. FOPID controller has five parameters to be tuned and provides two more degrees of freedom in comparison with the conventional PID controller. The performance of FOPID controller has been checked on 2-area power system and 75-bus real power system. A comparative study is also carried out between the results of FOPID and PID controllers. The obtained results demonstrate the effective performance of the FOPID controller and show the success and validity of FOPID controller in terms of performance parameters, i.e., settling time and oscillations.
