Frequency control in hybrid distributed power systems via type-2 fuzzy PID controller

Abstract

In this research article, a novel approach is proposed by considering a modified equilibrium optimization (MEO) algorithm based “interval type-2 fuzzy proportional integral derivative (IT2FPID) controller” for the load frequency control of the multi-area hybrid power system. The performance of the modified algorithm is tested by comparing it with the standard EO algorithm considering various standard benchmark test functions. Further, the efficacy of the MEO algorithm is tried by planning an IT2FPID controller for frequency regulation of the said hybrid system. The supremacy of the MEO-based IT2FPID controller is introduced by comparing its outcomes with MEO-based T1FPID structure, MEO-based conventional PID and EO-based PID controller techniques. It is observed that the MEO-based IT2FPID controller is more effective compared to others.
