Abstract

A method for protecting privacy in microgrids based on a homomorphic encryption algorithm and relates to the technical field of microgrid control includes: designing a distributed cooperative control method for a microgrid based on distributed control theory, to achieve frequency restoration of a microgrid; defining a technical essence of privacy protection and a scope of privacy protection; designing a method for protecting privacy in microgrids based on a homomorphic encryption algorithm according to defined technical essence of privacy protection and scope of privacy protection, and protecting initial and real-time values of each distributed power source in the microgrid from disclosure to neighbor nodes, to achieve a distributed cooperative control objective in the microgrid; and verifying the method for protecting privacy in microgrids based on the homomorphic encryption algorithm through simulation experiments. The method enhances trustworthy monitoring capabilities and privacy security during distributed cooperative operation of microgrids.
