About Differences between microgrid secondary control and Vf control
Microgrids as the main building blocks of smart grids are small scale power systems that facilitate the effective integration of distributed energy resources (DERs). • In normal operation, the microgrid is connected to the main grid. In the event of disturbances, the microgrid disconnects from the main grid and goes to the islanded operation.

This article provides a comprehensive overview of hierarchical control methods that ensure efficient and robust control for MGs. Specifically, it focuses on the secondary controller approaches (centralized, distributed, and decentralized control) and examines their primary strengths and weaknesses.
Secondary control: this control aims to compensate for the frequency and voltage deviations caused by the operation of the primary control. Normally, the secondary control acts over the primary control, changing the references of the primary control;.
The difference between the traditional secondary control and adaptive control is such that this adaptive control technique can optimize the parameters in real-time in Ref. Huang et al. (2022). In adaptive control, the adaptive algorithm plays a key role in reducing the switching frequency produced by source and load variations.
Microgrid structure with various hierarchy control techniques is categorized into three layers such as primary control, secondary control, and tertiary control techniques. A comprehensive literature review of these control techniques in AC microgrid is presented.
