Abstract

In this article, for load frequency control(LFC) in power system an improved sine-cosine algorithm is proposed with 2-DOF-PID controller. To facilitate the inspection, a multi-area test system(three area) has been developed. Additionally, several physical restrictions have been taken into account while investigating practical power system analysis. For every scenario considered for the experiment, the suggested approach has been employed as the optimizer of parameter of the controller of LFC. 2-DOF-PID controllers has the ability to quickly reject disturbances without noticeably increasing overshoot in set point tracking, have been utilised as the controller of LFC. The PIDF and FOPID controllers has been compare with 2-DOF-PID controller to evaluated the usefulness of it. The simulation results of SCA, SSA, ALO, and PSO are some of the algorithm with which of the proposed modified algorithm were compared, in three distinct scenarios: disturbance in three areas, disturbance in two areas, and the final scenario with physical restrictions. Wilcoxon Sign Rank Test (WSRT) has been use for the statistical analysis and 20 separate times was carried out in order to further prove the supremacy of the suggested strategy.
