An Effective SST-FLC for Mitigation of Reactive Power Compensation of DFIG Based Wind Energy Conversion System

Abstract

As wind-derived energy is increasingly incorporated into interconnected energy networks, this research attempts to control reactive power and regulates the voltages of wind energies. Since wind energy is volatile, it will generate unstable power and voltages. The reactive powers control of wind energy and faults on the grid is becoming more essential. One of a power system’s most crucial characteristics, it has a big impact on the stability of the whole thing. In terms of high-switching-frequency energy electronics generators, solid-state transformers (SST) may perform reactive power correction in WFs. The solid-state transformers suggested here connect wind farms powered by double-fed induction generators to the grids in place of energy transformers with real controllers in a conventional arrangement. The dual-active bridge converters and fuzzy logic controllers are both built into the solid-state transformers architecture. Power transmission between both sources of power can be accomplished using bidirectional DC–DC converters in either way. Modernized grid applications are the most promising ones for solid state transformers and increase the efficiency up to 96.61% with 0.91 Power factor of the entire power generation system with bit error rate of 0.2%. This will reduce the cost, improves the system’s efficiency, and also improves the system’s performance.
