Abstract


The renewable energy systems are going to take over most of the non-renewable energy systems, so many scientific efforts are being made to ensure the stability and reliability of the renewable energy systems. This paper is concerned about the wind energy systems and ensuring their behavior and performance during and after the abnormalities like fault ride-through. Two complete models of a grid connected wind systems are going to be simulated in the MATLAB software program, the first one will be a grid connected wind turbine driving a three-phase squirrel-cage induction generator (SCIG) and the other model will be a grid connected wind turbine driving a three-phase doubly-fed induction generator (DFIG). The frequency of each system will be displayed and compared to the frequency of the other system upon fault ride-through (three-phase short-circuit fault) and under the effect of the PID controller which is tuned by genetic algorithm technique. The different responses of both generators are going to be analyzed graphically and compared to each other upon the ride-through fault and under the effect of the designed controller (genetic algorithm PID controller).
