<![CDATA[Photovoltaic (PV) array under partial shade condition due to clouds or the shadow of buildings will make PV array get uneven irradiation. PV array with uneven irradiation will form multiple peaks on characteristic curve and will make the characteristic curve complex. In under partial shade condition, the conventional maximum power point tracking (MPPT) method can't reach to global MPP. MPPT based on meta-heuristic method can solve the PV characteristic curve problem that have multiple peaks. One of the meta-heuristic methods that can be used is Particle Swarm Optimization (PSO). The PSO method is used to solve the problem of the global maximum power under partial shade condition. The PV system consist of PV array, boost converter and MPPT implemented in MATLAB/Simulink. Experiments were carried out on 3 possible shadow patterns on 5 series connected moduls. The experimental results shows that overall MPPT PSO obtained an average tracking efficiency of 99,4275% with an average tracking time of 1.04 seconds. MPPT PSO can track the maximum power under partial shade condition.]]>
