“…To verify the effectiveness of the MHBA algorithm in solving the OPF problem, it has been compared with other optimization algorithms reported in the literature, namely, PSO [26,42,65], GWO [22,41], ABC [33], SCA [38], HHO [31], EGA [37], SA [66], DE [67], BHBO [47], GSA [28], BHBO [39], DSA [34], BBO [34] algorithms. In this comparison, the five objectives, fuel cost minimization, minimization of active and reactive power transmission line losses, minimization of VD, and enhancement of the voltage stability have been considered.…”
