Highlights:Graphical/Tabular Abstract SCA is based on sine/cosine mathematical functions. SCA is very effective in improving the dynamic stability of the power system. SCA has superior performance compared to BA and SOS techniques.
Conclusion:The superiority of the designed SCAPSS was verified by linear model stability analysis and nonlinear timedomain simulation. The results of the analysis have showed that the proposed novel approach provides faster damping and minimal overshoot of the low frequency oscillations in the rotor of the synchronous machine. In addition, SCA has performed better than the other two algorithms in terms of accuracy of final solution, convergence speed, computation time, damping ratio, and settling time of rotor angle.
