Drop control is one of the conventional and widely used methods for microgrid control. Drop control is in the first level of hierarchical control, and it is used in microgrid to adjust voltage and frequency independently, and it does not need to be connected. This method offers high reliability, and is usually used in inverters that form microgrids. Microgrids can work in two modes connected to the network and island mode. In this article, an overview of the application of the drop control strategy in inverter-based island microgrids is presented according to the studies. Droop control is an example of decentralized control, and the importance of droop control in the islanded mode of operation will become apparent when it is possible to share energy among all units without the need to communicate with other units. In the drop control method, the frequency and voltage are adjusted according to the load demand and power balance in the network. This review study shows the importance of using drop control and its improvement in microgrids.
