Employing PSO Approach to Minimize Total Harmonic Distortion in a PV-Based Inverter Systems

Abstract: The PV system's maximum power point (MPP) is nonlinear and depends on irradiance and temperature. Some situations allow many local maxima, but there is only one real MPP. This affects PV system power output, dependability, and complexity. Traditional approaches are slow and inaccurate for MPP determination. PSO is better for reducing steady-state oscillations in the inverter output current and voltage waveform. PSO is used to optimize inverter switching. In MATLAB, a PSO-based control algorithm and PI controller generate an error voltage, which is analyzed by the PSO controller to enhance switching. The photovoltaic bridge inverter system to reduce Total Harmonic Distortion (THD) and enhance power quality includes the PV array, DC-DC converter coupled in series, inverter fed by PSO-based controller, filter circuit, voltage and current sensors, and load. This model predicts PV system performance better when irradiance varies slowly. Photovoltaic power systems use controlled DC/DC boost converters called Peak Power trackers. Controlling the DC/DC converter conversion ratio maximizes solar panel output power. DC-DC converters connect modules and loads. Boost mode DC/DC converters are the most significant switching regulators. The PSO-based technology iteratively improves inverter switching and constant current and voltage waveform over a set time interval. This article analyses PV systems without and with PSO. PSO improves current and voltage waveforms, reducing steady-state oscillations. FFT study reveals that THD (IEEE Std.519) with PSO-based controller meets IEEE standards. System dependability increases.
