Power quality enhancement in wind turbine based DFIG using fuzzy control and neural-RIP for harmonic mitigation

Harmonic issue in the wind power plant is a concerning problem for both consumers and producers as that it affects the power quality of the distribution systems. This paper presents an improved control strategy for harmonic current compensation in wind turbine-based DFIG connected to the grid, using RIP-ADALINE for harmonic currents detection. A vector control-based fuzzy logic controller is applied to improve the active and reactive power flow. The active filtering is achieved using the grid side converter of the DFIG. The studied system has been simulated using MATLAB/SIMULINK platform. The results obtained show the effectiveness of the control strategies applied to the system Therefore the power quality in terms of grid current waveform, total harmonic distortion (THD) factor. frequency spectrum, and system power factor is improved within permissible standard values as defined by IEEE-519
