Novel application of Selfish Herd Optimisation based fractional order cascaded controllers for AGC study

In a modern, and complex power system (PS), robust controller is obligatory to regulate the frequency under uncertain load/parameter change of system. addition this, presence nonlinearities, load control (LFC) Power System becomes more challenging which necessitates suitable, controller. Single stage does not perform immensely against aforesaid changed conditions. So, novel non-integer/fractional order (FO) based two-stage incorporated with 2-degrees freedom (2-DOF), derivative filter (N), named as 2-DOF-FOPIDN-FOPDN controller, adopted improve dynamic performance 3-area Each area consists both non-renewable renewable generating units. Again, support superior it compared result produced by PID, FOPID, 2-DOF-PIDN-PDN controllers. The optimal design these controllers done applying Selfish Herd Optimisation (SHO) technique. Further, robustness authenticated evaluating parameter variation. work further extended prove supremacy SHO algorithm over recently published article on pathfinder (PFA).
