Maximum Power Point Tracking Control for a Photovoltaic System

The use of renewable energy has experienced significant growth as part of efforts to reduce fossil fuel consumption. Mexico, due to its geographical location, holds significant potential for solar energy development. However, this valuable resource remains underutilized, largely due to the low efficiency of photovoltaic panels. To meet user demand for power, implementing a power converter and control algorithms is essential. This article focuses on the implications of not having a voltage converter and analyzes the performance of various controllers applied to the Maximum Power Point tracking problem. Specifically, it examines Proportional Integral Derivative control, first-order sliding mode control, and Super Twisting sliding mode control under abrupt and smooth changes in temperature and irradiance. The objective is to determine the most efficient and reliable control strategy for solving the stated problem.
