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… These faults result in multiple local maximum power points in the P-V
characteristic where the classical P&O Maximum Power Point Tracking (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 in order to achieve maximum performance in the presence of different type of faults
