Experimental implementation of an electronic load for global maximum power point tracking
2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016This work deals with the partial shading effect in the power curve of a PV solar array. Using a semiconductor device — MOSFET or IGBT — as electronic load added to a buck converter, it is possible to scan the power curve of a photovoltaic string and therefore empirically determine its optimum voltage, even in presence of partial shading.

A Time-Based Global Maximum Power Point Tracking Technique for PV System
IEEE Transactions on Power Electronics, 2020This paper presents a new global maximum power point tracking (GMPPT) technique for the photovoltaic (PV) array under uniform as well as non-uniform solar irradiance. The proposed method uses the I–V characteristic of the PV array to track the global peak.

A High Speed Global Maximum Power Point Tracking Algorithm for PV Systems
2016Partial shading is one of the unfavourable conditions for photovoltaic modules since available power of them decreases. Besides that, maximum power point tracking becomes difficult in that kind of condition. Multiple maximum power points occur on the voltage - power curve of photovoltaic modules, if modules have bypass diodes.

Maximum Power Point Tracking (MPPT) is a technique employed to extract maximum power available from a photovoltaic (PV) module under varying atmospheric conditions. It traces the PV operating voltage corresponding to the maximum power point (MPP) and operates the panel at MPP. However, if a PV array is partially shaded, the conventional MPPT techniques

2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017
In this work, an Analog Global Maximum Power Point Tracker (A-GMPPT) is introduced and discussed. The underlying idea of this A-GMPPT is the peak power tracking using a capacitive load, in particular the filter input capacitance of the DC/DC converter.
