PV Systems Control Using Fuzzy Logic Controller Employing Dynamic Safety Margin under Normal and Partial Shading Conditions

Because of the unpredictable activity solar energy sources, photovoltaic (PV) maximum power point tracking (MPPT) is essential to guarantee continuous operation electrical generation at optimal levels. Several works have extensively examined from PV systems under normal and shading conditions. The fuzzy logic control (FLC) method one effective MPPT techniques, but it needs be adapted work in partial current paper presents FLC-based on dynamic safety margin (DSM) as an technique for a system overcome limitations FLC DSM performance index that measures state deviation situation. As index, used adapt controller output rapidly reach global maxima system. ability proposed algorithm its are evaluated using simulation practical implementation results single phase grid-connected operating
