Optimum MPPT Technique for Reconfiguring the Photovoltaic Array Under Partial Shading Failure

Abstract

Partial shading (PS) considerably restricts photovoltaic (PV) systems, requiring extraction of the global maximum power point (GMPP). This persistent challenge engenders continuous fluctuations in the maximum power point (MPP) and demands utmost attention. In this regard, this paper presents a novel hybrid scanning technique and a Perturb and Observe (P&O) algorithm meticulously designed to accurately track the PV array's GMPP encountering PS, non-uniform dust deposition, or any common failures. Furthermore, it serves as an efficient tool that operates in tandem with the dynamic reconfiguration approaches. Extensive simulation tests were carried out using MATLAB Simulink software, while the validation and verification processes were conducted using an integrated Arduino board. Consequently, the simulation results exhibit outstanding accuracy and stability.

A review of recent control techniques of drooped inverter‐based AC microgrids

“…The intermittent nature of power supplied from the RES generation makes the ESS an indispensable component to keep the power balance between generation and consumption 136 . In island microgrid comprised of the ESS and RES generation, the ESS unit usually operates as a grid‐forming unit that regulates the AC bus, while the RES works as grid‐feeding units that inject all available power into the system 137 .…”
