IoT-based grid-tied PV system voltage stability enhancement using novel integrated converter and cascaded neuro-fuzzy MPPT

A novel boost integrated KY converter with reduced converter size, smaller output ripples and higher efficiency is introduced in this research for improving voltage level of PV system that is integrated to the grid. To further improve the efficiency of the converter, a novel Cascaded Type II ANFIS Maximum Power Point Tracking (MPPT) is also introduced. The suggested MPPT technique, along with optimal power tracking, is also modelled to assert control over voltage and current produced by converter. Moreover, the PV generated power is synchronized perfectly to grid power, using voltage source inverter, which is controlled by using dq theory and PI controller. Additionally, Internet of Things (IoT) is used for the real-time monitoring of parameters that influence the reliability and performance of the grid-tied PV system. The IoT-based parameter monitoring also aids with optimization of energy production and consumption by facilitating proper system maintenance. The validation for the proposed control strategies is obtained using MATLAB simulation and laboratory-scaled prototype execution, which are carried out under both constant and variable operating conditions. Furthermore, the peak efficiency of the suggested boost integrated KY converter is estimated as 98.4% according to the derived results.
