Abstract:
In this work we present a fault-tolerant control strategy to extract the maximum power from
photovoltaic (PV) panels. The performance of PV panels is affected with different type of faults
such as mismatch, shading, cell degradation, different type of panels, soiling…. This faults result in
multiple local maximum points in the P-V characteristic where the classical P&O MPPT algorithm
is unable to achieve the global maximum power point. The proposed method is based on the use of
a hybrid Particle Swarm Optimization and a classical PI controller to achieve the maximum
performance in the presence of different type of faults
