This paper presents the design and simulation of a standalone solar photovoltaic (PV) system incorporating a high-gain boost converter (HGBC) and a seven-switch, single-phase 15-level inverter. The system employs a hybrid Artificial Neural Network-Particle Swarm Optimization (ANN-PSO) maximum power point tracking (MPPT) algorithm alongside sinusoidal pulse-width modulation (SPWM) control. The HGBC efficiently steps up the PV-generated DC voltage, while the 15-level inverter enhances power quality with a staircase AC output. Simulations in MATLAB/Simulink under standard test conditions (STC) and dynamic irradiance variations confirm stable DC regulation, effective AC conversion, and adaptability to changing solar conditions. Total harmonic distortion (THD) analysis shows 14.98% under STC, rising to 16.52% under varying irradiance. Despite fluctuations, the system ensures reliable energy conversion, making it a viable solution for standalone PV applications.

摘要

This paper presents the design and simulation of a standalone solar photovoltaic (PV) system incorporating a high-gain boost converter (HGBC) and a seven-switch, single-phase 15-level inverter. The system employs a hybrid Artificial Neural Network-Particle Swarm Optimization (ANN-PSO) maximum power point tracking (MPPT) algorithm alongside sinusoidal pulse-width modulation (SPWM) control. The HGBC efficiently steps up the PV-generated DC voltage, while the 15-level inverter enhances power quality with a staircase AC output. Simulations in MATLAB/Simulink under standard test conditions (STC) and dynamic irradiance variations confirm stable DC regulation, effective AC conversion, and adaptability to changing solar conditions. Total harmonic distortion (THD) analysis shows 14.98% under STC, rising to 16.52% under varying irradiance. Despite fluctuations, the system ensures reliable energy conversion, making it a viable solution for standalone PV applications.
