One of the major drawbacks of PhotoVoltaic (PV) systems is represented by the effect of module mismatching and of partial shading of the PV field. This paper proposes a method of maximum power point tracking using Quantum behaved Particle Swarm Optimization (QPSO) for grid-connected photovoltaic systems. The system is composed of a boost converter and a single-phase inverter connected to a utility grid. The maximum power point tracking control is based on proposed control a switch of a boost converter. QPSO controllers provide attractive features such as fast response, good performance. The single phase inverter uses predictive current control which provides current with sinusoidal waveform.
