Maximum power point tracking (MPPT), partially shaded conditions (PSC), global maximum power point (GMPPT), particle swarm optimization (PSO)

Abstract:

Many techniques are improvised with the help of maximum power point tracking but now we are examining the combination of global maximum power point tracking (GMPPT) with search- skip-judge method (SSJ) and rapid method (R) by forming a (SSJ-GMPPT) and (R-GMPPT) Which helps to track maximum power from PV string. And Particle Swarm Optimization algorithm (PSO) is used to reduce the tracking time. The mentioned methods are reduces the searching voltage range on current and voltage (I-V) and power and voltage (P-V) characteristics of PV string under partially shaded conditions (PSC).
