A resilient distributed energy management algorithm for economic dispatch in the presence of misbehaving generation units

Abstract

The legacy power system is gradually evolving into the smart grid. A variety of distributed control algorithms are being applied for smart grid energy management applications because of their flexibility, robustness, and local communication and computation features. These algorithms, however, increase the vulnerability of smart grid to adversaries. Thus, there is an urgent need to protect the distributed energy management algorithms from malicious cyber-attacks. A reputation-based distributed energy management algorithm is proposed to guarantee an accurate control computation in distributed energy management algorithms to solve the economic dispatch problem in the presence of misbehaving generation units. The proposed method is capable of performing a resilient distributed control without a central coordinator and allows all the wellbehaving generation units to reach the correct state asymptotically. The effectiveness of the proposed method is illustrated through simulation case studies.
