Experimental Validation of a Photovoltaic Scan Circuit for Global Maximum Power Point Tracking

2018 IEEE ANDESCON, 2018
This paper presents the partial shading effect on a solar photovoltaic system and proposes a circuit for scanning the power-voltage curve. In the first part of this document the partial shading effect is presented, then an experimental set-up is shown where a simple Perturb & Observe algorithm is trapped in a local point of maximum power.

Global maximum power point tracking method under partial shading conditions

2015 IEEE Advanced Information Technology, Electronic and Automation Control Conference (IAEAC), 2015
The power characteristics of photovoltaic systems can have multiple peaks when under partially shading conditions which can cause traditional power tracking methods to operate at the lower power peaks. This paper presents a global maximum power point tracking method under partially shading conditions.

A Fast Global Maximum Power Point Tracking Technique for Partially Shaded PV Arrays

2018 IEEE International Students' Conference on Electrical, Electronics and Computer Science (SCEECS), 2018
This paper proposes a new global MPPT method for PV array under non-uniform insolation. The proposed method first tracks the knee point using I-V characteristic which is near to the local peak of the P-V curve. Then it compares the measured power at various knee points to find the region containing global peak.
