Power Quality Improvement of Grid Tied Hybrid Power System by Using ANFIS Controller

The primary objective of this paper is to inspect the fuzzy controller for MPPT in PV system integrated with a wind system and linked to the grid using a DC–DC converter and PWM rectifier. To address power quality issues, the proposed FUZZY MPPT algorithm is expected to provide precise and efficient MPPT tracking, thereby reducing power fluctuations in real-time applications. The use of a flyback converter with a single switch is expected to improve the system's efficiency. Moreover, the paper suggests using a multilevel inverter topology with multicarrier reference PWM technique to convert DC to AC with fewer power switches with a higher count of voltage stages at the output. The intended system will be simulated in MATLAB and compared with existing PI and fuzzy controllers. The study will also validate the assessment of the flyback converter among the FUZZY set of rules and ANFIS controller through grid synchronization. The converter and inverter's performance will be tested using a DSPIC30F2010 microcontroller to ensure their proper operation.
