Multiple-to-single maximum power point tracking for empowering conventional MPPT algorithms under partial shading conditions

Partial shading conditions (PSC) in photovoltaic (PV) systems degrade energy harvest by generating multi-peak power-voltage (P-V) curves, trapping conventional maximum power point tracking (MPPT) algorithms at local maxima. This paper presents a Multi-Peak to Single-Peak Conversion (MSMPPT) framework that enables like Perturb & Observe (P&O) and Incremental Conductance (INC) reliably track the global (GMPP) under PSC without structural modifications. The operates via two stages: dynamic estimation of optimal voltage boundaries shrink GMPP search space 10% original P-V range, active regulation enforce operation within this zone, effectively transforming curve into single-peak profile. proposed MSMPP-P&O MSMPP-INC achieve 50% faster (64 ms vs. 122 for P&O) near-perfect steady-state efficiency static shading, reducing losses below 2%. In scenarios with abrupt irradiance shifts, MSMPPT maintains robustness less than 1.5 W net loss, outperforming methods incur over 30 losses. By eliminating oscillations hotspot risks through regulation, retains algorithmic simplicity while enhancing performance complex scenarios. Validated across benchmark profiles, demonstrates fidelity requiring additional hardware or optimizers. innovation bridges gap between MPPT partial resilience, offering cost-effective, scalable solution boost PV system reliability environments.
