In this paper, information detection-based secondary control strategy is proposed for a low voltage islanded microgrid (MG) framework. The reference information is not available with all distributed generators (DG) in a clustered and meshed low voltage MG due to communication contingencies. Hence, an information detection strategy (IDS)-based control scheme is proposed to update the reference information locally at each DG terminal. Initially, in primary control layer droop boost controller is locally implemented to stabilize the MG voltage and frequency after islanding load disturbance. Then in the secondary control layer, an IDS is used to provide the reference points to every DG unit connected in the MG. Further, a consensus-based protocol is proposed to restore the voltage and frequency to their reference values in fixed time. The proposed controller is self-reliant and is independent of system parameters. The rigorous Lyapunov stability analysis is presented for guaranteed convergence. The test setup is simulated in MATLAB/Simulink to validate the effectiveness under load perturbation, DG dropout, and scalability.
