External Current Source–Based Unilluminated PV Partial Shading Emulation System Verified Through the Hybrid Global Search Adaptive Perturb and Observe MPPT Algorithm

In this study, a novel PV emulator and the state-of-art learning–based real-time hybrid global search adaptive perturb observe (P&O) maximum power point tracking (MPPT) algorithm have been presented. The prime objective of constructed based on integration unilluminated solar panels with an external current source to overcome constraints such as need for wide surrounding space, high installation cost, lack control over environmental conditions. Moreover, developed resolved drawbacks conventional P&O MPPT method associated use constant perturbation size that leads poor transient response, continuous steady-state oscillation, inefficient performance voltage in presence partial shading. intended has verified using MATLAB/Simulink by applying comparative analysis MPPT. addition, proposed scheme is validated experimentally implementation MATLAB/Simulink/Stateflow dSPACE Real-Time-Interface (RTI) 1007 processor board DS2004 A/D CP4002 Digital I/O boards. results indicate effective reducing losses faster speed less oscillation. excellent dynamic characteristics proven be ideal tool testing inverters various algorithms commercial applications university studies.
