Photovoltaic Panel performance against partial shading using intelligent bypass diode and clustered adaptive P & O
Photovoltaic Solar Panel Performance, Partial Shading, Smart Bypass Diode, Maximum Power Point Tracking, Adaptive and Clustered P&O.
The exponential growth in the use of photovoltaic solar (PV) energy makes that the question of the performance of panels connected to the grid is extremely relevant, because its efficiency is relatively low if compared to other energy sources. Among the main studies, the following stand out: Partial Shading (PS) and Maximum Power Point Tracking (MPPT). The PS refers to the distinct levels of irradiance along the photovoltaic panel and the MPPT refers to the maximum power point tracking according to ambient conditions. In this work, a current photovoltaic panel with 72 cells, containing a modern smart bypass diode configuration was modeled and simulated. In order to verify the performance of the photovoltaic panel were simulated partials shadings and the maximum power point tracking using the simplest MPPT technique: Perturb & Observe (P&O), however modified with adaptive step and clustered.
