Cyber-Resilient Consensus Secondary Control Scheme for Microgrids with Two-Hop Communication Links

This paper proposes a cyber-resilient consensus control scheme for multi-agent microgrids, which reduces network connections using two-hop communication links. First, it utilizes a method, known as Weighted-Mean-Subsequence-Reduced (W-MSR), where each agent eliminates state values of neighbors that are significantly higher than its own state value. Subsequently, it presents the multi-hop weighted MSR method, where sending agents transmit not only their own state value but also the data of their neighbors to the receiver agents. This approach, referred to as the two-hop communication method, aims to reduce network connections. Our results demonstrate that employing the two-hop technique leads to a reduction in network connections. The effectiveness of the proposed method is verified via simulation results conducted in MATLAB/Simulink.
