PDPID Plus DDF Cascaded Controller for LFC Investigation in Unified System with Wind Generating Unit

A hybrid innovative Proportional derivative Proportional integral derivative plus double derivative filter controller has been suggested to make balance system frequency over an unequal two area reheat turbine based thermal-wind power grid network. This research paper has implemented SOS algorithm to optimize the constriction of hybrid controller with presence a disruption of 0.01 p.u. to validate system sturdiness in area 1 as well as in both areas. A cost function called as integral time absolute error (ITAE) has been considered to achieve the finest gain values of the projected novel controller. The vigorous outcomes of the modelled hybrid cascaded controller have compared with normal PID controller over modelled power system network. Finally, the proficiency of the executed hybrid cascaded controller is examined by introducing GDB (governor dead band) as well as GRC (generation rate constraints).
