Abstract :
Since wind energy is intermittent in nature, the power variation significantly affects the stability of isolated power system and result in frequency deviation. This paper presents the frequency deviation analysis of wind, aqua-electrolyzer, fuel cell and diesel generator based hybrid power system with different controllers. The mismatch between total power generation and load demand is minimized by the help of PI, H-infinity with LMI and loop shaping control approach. The simulated results in MATLAB/SIMULINK show better performance in case of H controller with loop shaping approach as comparison to other two controllers.
