Multimachine power system stability improvement using butterfly algorithm tuned controller design.

Enrichment of power system stability plays a major role in the current ages. This act is due to the increase of power system structures which causes a low frequency oscillation. These problems are solved by implementing various methods. This paper gives the best solution to solve the low frequency oscillation problems which are based on optimization criteria of a generator and load angle. For better tuning of the controller parameters, Butterfly optimization algorithm is used. The simulation results for Butterfly Algorithm based controller design are compared with the performances of conventional and Firefly Algorithm based controllers. [ABSTRACT FROM AUTHOR]
