Stability in DC microgrids

This study addresses the distributed adaptive droop control method to enhance power sharing and voltage regulation in DC microgrids. Traditional fixed droop control mechanisms require high droop coefficients to improve load-sharing accuracy, which can lead to voltage fluctuations. Additionally, centralized control mechanisms impose scalability limitations due to high communication requirements. In this research, a decentralized control approach is adopted, enabling communication between converters in the microgrid only through neighboring units. The proposed adaptive droop control method dynamically adjusts the power-sharing ratio of each converter based on environmental information. In the study, simulation analyzes were carried out to test the accuracy and effectiveness of the method. The results demonstrate that the proposed adaptive control strategy enhances power-sharing accuracy, improves voltage regulation, and provides significant advantages in terms of system scalability. This study aims to contribute to the development of a more efficient and reliable energy management system in DC microgrids.
