Hybrid Maximum-Power-Point Tracking Algorithm using Voltage Sweep and P & O for T-Source Inverter PV Applications

In this article, the analysis and implementation of a hybrid algorithm for maximum Point of Power tracking in photovoltaic applications is presented. The proposed algorithm merges the Voltage Sweep technique and the Perturb & Observe (P& O) algorithm to control a T-source inverter (TSI). The quadrature-axis component, on the other hand, is set to zero to improve the system’s power factor. After calculating the reference components, they are compared to actual values, and two PI controllers handle them. Then, the Simple Boost Control technique is employed to modulate the TSI. Various operational scenarios, such as irradiance and temperature variations, were simulated (using MATLAB) and investigated to validate the efficacy of the proposed algorithm. A quantitative comparison between the three methods is included.
