AFLL-Based Control Technique for Grid Interfaced Three Phase PV System By Using Fuzzy Logic Controller

Mahesh Kumar Dwarapudi

In this study, an Advanced Frequency Locked Loop (AFLL)-based fuzzy logic control approach for a three-phase double-stage grid-interfaced solar photovoltaic (PV) system is being developed. This AFLL-based algorithm isolates the system in the event of a grid fault, extracts the essential components of the load current, eliminates harmonics, balances the grid current, and optimises system performance under distorted grid conditions. The harmonic distortion is decreased by the fuzzy logic controller, which also evaluates the precise values. In order to regulate voltage, the fuzzy logic controller replaces the PI controller. In a long radial network, the distant endpoints have a voltage quality issue, but this controller preserves the grid power quality by supplying the necessary reactive and active power to the grid. Even in the worst cases of DC offset, solar insolation variation, load unbalancing, grid faults, voltage distortion, voltage unbalance, and voltage swell/sag, the PV system's Voltage Source Converter (VSC) is able to supply PV energy to the grid. An adjustable DC link voltage is used to lower the VSC switching losses. Using the matlab/simulink software, the effectiveness of the proposed technique is evaluated.
