Abstract Microgrids integrate various distributed energy resources to enhance reliability and sustainability. Power electronic converters are vital in microgrids since they provide efficient, reliable, flexible operation. There numerous controllers available that can be applied these converters, lately, fractional-order (FOC) have gathered huge recognition. These enhanced flexibility superior performance managing dynamic behavior. structures of FOCs, this article predominantly focuses on comparing different cascaded fractional order (C-FOC). Four distinct topologies proportional integral (C-FOPI) selected for comparison with one another the controller used a non-minimum phase converter, such as boost converter employed microgrid system. The optimized using Elephant Herd Optimization (EHO) algorithm Integral Time-weighted Absolute Error (ITAE) serving metric. Each is subject variation system changes, outcomes documented correlated ascertain optimum structure. simulation endorsed notable advancements terms transient steady-state performance, featuring improved resilience parameter reduction 36.6% settling time, 15% overshoot, 20.1% rise an margin more than 51% 50% indices compared traditional (PI-PI).
