Modeling of PV module to study the performance of MPPT controller under partial shading condition

Abstract

This paper proposes the mathematical modeling of Photovoltaic (PV) module using single diode model and use it to study the performance of PV array under partial shading condition. Partial shading is one of the major causes of reducing energy output in solar PV array. Due to partial shading, PV characteristics get more complex. In order to extract maximum power under shading condition, its performance has to be studies. In this paper, Matlab based mathematical model is used to study the performance of Perturbation & Observation (PO) based Maximum Power Point Tracker (MPPT) controller under partial shading condition. Further, ecosense Insight Solar PV Training kit is used to justify the mathematical model.

Analysing the Effects of Thin Object Shading on PV Sources: A Dual Approach Combining Outdoor and Laboratory Solar Simulator Experimentation

“…Since the inception of PVs, extensive research has delved into investigating the effects of shading on PV systems. These research studies have led to PV systems being fitted with bypass diodes to mitigate the effect of shade mismatch, MPPT trackers to reduce the repercussions of shade on multiple modules, and wiring reconfigurations to avoid multiplication of the energy lost on other modules [3][4][5]. While these mitigation measures have been proven to be vital solutions to the shading effect on PV systems, the studies that delve deep into these three main components primarily focus on the partial shading caused by hard, peripherally defined shadows such as walls and buildings.…”

A Solution of Implicit Model of Series-Parallel Photovoltaic Arrays by Using Deterministic and Metaheuristic Global Optimization Algorithms

“…Hence, the operating conditions (i.e., irradiance and temperature) of the shaded submodules are different than the operating conditions of the rest of the submodules [8]. In this case, it is said that the generator operates in nonhomogeneous conditions and the generator's I-V curve may present multiple knees, which is translated into multiple MPPs in the P-V curve [9]. To model a PV generator operating in nonhomogeneous conditions, it is necessary to consider that each submodule in a module is represented by the SDM.…”
