Performance Evaluation of an Inverter-Based Microgrid Under Cyberattacks

Distributed renewable energy resources (DER) are interfaced in a microgrid through power electronic converters (PEC). PECs utilize different types of sensors for their reliable and stable operation. However, as the ratings of a DER increase, its interfacing PEC becomes more sophisticated requiring more sensors. This will make PECs more vulnerable to sensor malfunctions, which may be caused by cyberattacks. This paper analyzes the performance of a microgrid under sensor malfunction attacks in PECs for different scenarios in MATLAB/SIMULINK and provides a final evaluation based on the acquired results.
