Two model-based fault-tolerant control design strategies are presented for a Diesel Engine Generator (DEG) working as a master generation unit in an islanded microgrid consisting of a hybrid wind-diesel-photovoltaic power system with a Battery Storage System (BSS). A Model Predictive Control (MPC) scheme and a Model Reference Adaptive Control (MRAC) scheme have been selected for precise and stable voltage and frequency regulation in the DEG. A Fault Detection and Diagnosis (FDD) module is added to the MPC structure, in order to reconfigure the control strategy when actuator faults in the DEG are present. MRAC is used in combination with a PID controller tuned by a Genetic Algorithm (GA). Improved performance over a baseline controller, IEEE type 1 Automatic Voltage Regulator (AVR), is achieved in a developed realistic simulation environment based on Matlab/Simulink.
