The solicitations of the variable speed wind generators need control to operate the wind energy system. Maximum power point algorithm is one of the promising solution to harness maximum energy from the renewable energy source. The study represented in this paper comprises comparative analysis of two MPPT algorithms which is used in standalone wind energy system to extract maximum power from the wind. The comparative analysis is done for Variable current perturbation MPPT algorithm and Variable step P & O MPPT algorithm. The variable current perturbation algorithm and variable step perturbation algorithm is simulated and the performance is studied with the fixed pitch angle and variations in the pitch angle. The electrical parameter like voltage and current is sensed for current perturbation algorithm and angular speed and shaft power is sensed in case of variable step perturbation algorithm. The variable current perturbation algorithm senses MPPT using electrical parameters and the variable step perturbation senses mechanical parameters. The effect of pitch angle for both the algorithms is also introduced to check the power generated from wind energy system.
