This paper presents dual-stage fractional order PID controller to enhance the primary frequency regulation of interconnected multi- $\mu $ grids in standalone mode. A rational. non-integer ordered calculus-based controller is assessed via a single-area microgrid system pursued by a two-area microgrid to integrate a tidal power plant (TPP).
