Implementation of FLC-Based Adaptive Droop Control in a DC Microgrid with Generation Uncertainties

Due to the environmental impact caused by Conventional Generator Sources, Renewable Energy is being considered. Intermittent generation in Renewable Energy calls for the implementation of microgrids. This study uses an IEEE 9-Bus DC Microgrid. Voltage Regulation is one of the issues of a Microgrid, while Power output is an issue for Converters. Traditional Droop Control Technique is used to regulate voltage where the Voltage follows a linear curve. However, this technique does not provide a good trade-off between Voltage and Power as Droop Coefficient is constant. An Adaptive Droop Control technique is implemented, where Droop Coefficient is made adaptive using Fuzzy Logic Controller. A Trade-off Value is calculated to determine the results, and FLC-based Adaptive Droop Control outperformed Traditional Droop Control in that aspect. Therefore, FLC-based Adaptive Droop Control can be considered a viable alternative to Traditional Droop Control.
