Distributed Privacy-Preserving Active Power Sharing and Frequency Regulation in Microgrids

To avoid potential privacy threats and associated cyber-security issues in microgrids, this letter presents a distributed active power sharing and frequency regulation method with preserved privacy of local information. In the proposed approach, the transmitted data including the active power outputs and capacities are protected by adding noise to the original ones. Theoretical analysis and verification studies are performed to illustrate the advantages of the proposed method.
