Under loss of utility power, a microgrid must regulate voltage and frequency within the grid, and therefore these controls would be well suited to microgrids. . Islanded microgrids commonly use droop control methods for autonomous power distribution; however, this approach causes system frequency deviation when common loads change. This deviation can be eliminated using secondary control methods, but the core of this approach is to generate compensation. . This article proposes an autonomous hierarchical frequency control scheme for an island microgrid that utilises the advanced combination of proportional resonance and harmonic and model predictive control methods to ensure isolated microgrid operation in different scenarios. Our researchers evaluate in-house-developed controls and partner-developed microgrid components using software modeling and hardware-in-the-loop evaluation platforms. The Load Frequency Control (LFC) scheme has been a profoundly investigated matter for decades for achieving a consistent frequency. This study introduces a novel. .
