Dynamic exploitation Gaussian bare‐bones bat algorithm for optimal reactive power dispatch to improve the safety and stability of power system

Here, a novel Gaussian bare-bones bat algorithm (GBBBA) and its modified version named as dynamic exploitation (DeGBBBA) are proposed for solving optimal reactive power dispatch (ORPD) problem. The plays fundamental role in ensuring stable, secure, reliable well economical operation of the system. GBBBA employs distribution updating positions an effort to mitigate premature convergence problem associated with standard BA. DeGBBBA is advanced variant which introduced so allow adaptation algorithm. Both used determine settings generator bus voltages, tap setting transformers shunt sources order minimize active loss, total voltage deviations stability index. performance effectiveness algorithms demonstrated on three system test including IEEE 14-bus, 57-bus 118-bus. Simulation results show that robust effective ORPD
