Abstract : This paper proposes an intelligent anomaly detector integrated with droop controllers in Distributed Generators (DGs) for enhancing the system resilience condition during the event of cyber-attacks/threats in the smart distribution grid. Two different droop controllers are considered, among these the P-F controller is utilized by DGs of medium voltage grids and the P-V droop controller is used by DGs in low voltage microgrids. The ANN-based intelligent controller can detect the anomaly/cyber threat information from the DSO/Main Control center or from the individual microgrid control center and can switch the DGs to autonomous operating mode using the P-V/P-F droop controllers and thereby supporting the grid at the time of cyber vulnerability and grid instability condition. The proposed idea is simulated and verified the performance using MATLAB/Simulink.
