In this current work, one of the maiden approaches was made frequency regulation in a Standalone AC Microgrid (μG) by considering Spotted Hyena optimizer based Cascaded PI-PD controller. These μGrid can be formed by merging some the isolated such as renewable energy resources, wind power and also solar electricity irradiations. Discrepancy any these-sources will influence system frequency and hence-frequency control-theme in MG was challenging issue for all-the researchers. Inspite of these struggling this current paper consider a-Cascaded PI-PD-controllers as secondary frequency controller for the-Standalone μGrid, and a novel Spotted Hyena Optimizer (SHO) is used to tuning and obtaining the controller parameters. The proposed cascaded controllers inspected on a μGrid test system, and robustness is assessed considering -dissimilar variations in load. In order to manifest the effectiveness of the Cascaded PI-PD controller, it-is being compared to some more conventional controller as Proportional Integral (PI), and Proportional Integral and-Derivative (PID) controllers and also to verify the-potency of the-Spotted Hyena optimizer, the-results obtained-by the SHO are been-compared with other intelligence swarm-techniques.
