Therefore, in this research work, a comprehensive review of different control strategies that are applied at different hierarchical levels (primary, secondary, and tertiary control levels) to accomplish different control objectives is presented. . High penetration of Renewable Energy Resources (RESs) introduces numerous challenges into the Microgrids (MG), such as supply–demand imbalance, non-linear loads, voltage instability, etc. Hence, to address these issues, an effective control system is essential. However, challenges, such as computational intensity, the need for stability analysis, and experimental validation, remain to be addressed. The energy sources in DGs may include both renewable and non-renewable sources.
