This paper analyzes control scheme sensitivity to changes in irradiance and temperature around the maximum power point (MPP) for photovoltaic (PV) panels. Conventional control schemes such as constant voltage, current, and resistance, as well as a newly introduced voltage-offset resistance control (VRC) are compared. Based on experimental PV data and a validated model, VRC is found to have the lowest sensitivity to typical transients. Stability analysis of a buck and boost converter under VRC… CONTINUE READING
