Abstract:

In order to fix the shortcomings of traditional derivative-based methods and other intuitive-over-algoritms, this study has suggested the use of the core optimization algorithm (GOA), which is a new intuitive-over-technique, in the curved design of the controller-made power system stable sword (PSS). FOPID type PSS parameter adjustment problem was converted into an optimization problem with a target function based on the time definition area and solved with GOA. The proposed approach was applied to the multi-machine power system that was exposed to different charging conditions and failures. Recommended GOA-based newly designed FOPID-made solid sword (GOA-FOPIDPSS) performance was compared to GA-, ABC- and also Recommended GOA-based classic solid swords. The superiority, potential and rigidity of the recommended solid sword was confirmed through nonlinear simulation work and some dynamic performance index. The results of the analysis showed that the recommended GOA-FOPIDPSS controller provides excellent disconnection performance for low-frequency releases in different failures and broad working conditions.
