This paper presents a comprehensive literature review of microgrid control functions and services that address complexities related to integrating renewable energy, transitions between grid-connected and islanded operational modes, and the need for reliable power supply.

The droop control is carried out by replacing the traditional droop line with hyperbolic tangent curve, which makes the droop coefficient adjust dynamically with the change of the system, and makes the micro-grid adopt droop control strategy to adjust the.
