This paper presents a cyber-secure control method that enables an attack resilient operation of grid connected electronically coupled distributed energy resources (DERs). First, adverse impacts of attack templates such as denial of service, replay attack and bias injection on the DER system performance are demonstrated. It is shown that each attack scenario can drive the DER system to an unsafe state and jeopardize the system stability. To ensure the safe operation of DER in the presence of attacks, a sliding mode based observer is designed to detect and estimate the attacks. The estimated attacks are then used to compensate for corrupted data. The effectiveness of the proposed cyber attack mitigation method is demonstrated through simulation results applied to a detailed nonlinear (switch) model of a three-phase converter-base DER.
