Abstract Droop control is at the first level of hierarchy and does not require communication. Having high reliability, usually used in inverter‐based microgrids. The microgrid can operate as an island, it also be connected to main or auxiliary grid. By reviewing extensive literature on role controller microgrids for island mode operation, this study, droop regulation strategy has been covered briefly compactly. example decentralized basic control, its importance revealed operation when possible share power all facilities without needing communicate with other units. Disadvantages common such slow transient dynamics low energy quality non‐linear unbalanced loads, have limited use advanced Therefore, various methods improve investigated so far, some which mentioned. This study highlights application strategies order coordinate distributed generation units microgrid. About 180 published studies field reviewed, classified indexed quick reference.
