Abstract	This study presents two proposed adaptive and intelligent control schemes for accurately adjusting the MG voltage and frequency in islanded mode and ensuring the seamless transition between islanded and grid-connected modes. The two proposed controllers are based on improving the performance of the droop control method depending on H-infinity and model predictive control methods. However, when the MG connected to the utility grid, the MG is related to the grid voltage and frequency and the active and reactive power transfer is adjusted using the P/Q control method. Firstly, this study presents a comprehensive review of the commonly used control schemes in MGs. Then, the structure of the two proposed controllers is described and the Simulink model is presented. The controller is applied to an MG test system to validate its capability to meet requirements. In addition, a comparison between the two proposed controllers is made based on the integral of square error (ISE), integral of absolute error (IAE), and integral time-weighted absolute error (ITAE). The results prove that the two proposed control schemes have the ability to adjust the MG in its two operating modes and also provide a seamless transfer between the islanded and grid-connected modes of MGs.
