Abstract

The growing number of grid-connected solar systems (PVSs) presents new issues for power system operators in terms of maintaining electricity quality and grid dependability. Following that, the flexible power point tracking (FPPT) algorithm is established in order to implement grid-support features and address negative impacts caused by PVSs' high penetration level, such as overloading and over-voltage. However, only a few pieces of research investigated partial shading conditions (PSCs) in practical operation and encountered scanning technique and implementation complexity limits. To solve these concerns, this paper proposes a global FPPT (Glob-FPPT) control with key point estimation that is extended to PSCs and has a rapid convergence speed. The sampled representative current-voltage pairs from the initialization procedure are used to construct an explicit PV model that expresses the main operating points under PSC and guarantees dynamic performance. Simulations and experimental assessments under various PSCs verify the efficiency of the proposed Glob-FPPT control.
