Maintaining a power balance between generation and demand is generally acknowledged as being essential to maintaining a system frequency within reasonable bounds. This is especially important for linked renewable-based hybrid power systems (HPS), where disruptions are more likely to occur. This paper suggests a prominent modified “Fractional order-proportional-integral with double derivative (FOPIDD2) controller” as an innovative HPS controller in order to navigate these obstacles. The recommended control approach has been validated in power systems including wind, reheat thermal, solar, and hydro generating, as well as capacitive energy storage and electric vehicle. The improved controller’s performance is evaluated by comparing it to regular FOPID, PID, and PIDD2 controllers. Furthermore, the gains of the newly structured FOPIDD2 controller are optimized using a newly intended algorithm terms as squid game optimizer (SGO). The controller’s performance is compared to benchmarks such as the grey wolf optimizer (GWO) and jellyfish search optimization. By comparing performance characteristics such as maximum frequency undershoot/overshoot, and steadying time, the SGO-FOPIDD2 controller outperforms the other techniques. The suggested SGO optimized FOPIDD2 controller was analyzed and validated for its ability to withstand the influence of power system parameter uncertainties under various loading scenarios and situations. Without any complicated design, the results show that the new controller can work steadily and regulate frequency with an appropriate controller coefficient. [ABSTRACT FROM AUTHOR]

In this article, four elements circularly polarized trapezoid multiple inputs and multiple outputs (MIMO) antenna for UWB application is presented. The electrical dimension of presented four elements MIMO antenna in term of lambda (λ) is 0.44λ × 0.44λ × 0.012λ. The novel loop parasitic is used for the enhancement of isolation and impedance bandwidth. The reflection coefficient (Sij ∈ i = j) is less than − 10dB in range of 2.4 GHz and 13.5 GHz and isolation (Sij ∈ i ≠ j) is greater than 22dB in given range. The axial ratio bandwidth (ARBW) of presented trapezoid antenna is 3.6 GHz; less than − 3dB in the range of 6.7 and 10.3 GHz. The peak gain is 5.9dBi, diversity gain (DG) > 9.89dB and envelope correlation coefficient (ECC) < 0.022. Various other parameters such as radiation pattern, reflection coefficient, Isolation, multiplexing efficiency, ECC, DG and peak gain are discussed in detail for experimental validation.
