| Abstract |
The distributed economic dispatch (ED) algorithm carried out in an AC microgrid (MG) is a promisingsolution which guarantees flexibility, scalability and reliability over single point failure as compared tothe centralized approach. Not to mention, the integration of communication infrastructure for information exchanges on one hand adds feasibility for the distributed operation but at the same time, is a threat to the smart grid. The attackers can penetrate in the communication links and inject malicious data in order to gain economical benefits, disrupt the proper functioning of the system etc. Hence, the investigation of the effect of cyber attacks on cooperative energy management (CEM) is an important concern both theoretically and practically. This paper analyses the impact of cyber attacks on a CEM, optimizing ED to a sub-optimal value in an islanded AC MG. The response of the system over false data injection (FDI) and hijacking attacks is further demonstrated on a real-time (RT) co-simulation platform. |
