Exploration of partial shading condition in photovoltaic array
2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017Photovoltaic (PV) power generation is the most promising renewable energy source. Photovoltaic module has dynamic characteristics with respect to irradiance and temperature. To extract maximum power from PV module maximum power point tracking algorithms are used. These algorithms are trained according to dynamic characteristics of PV module.

Analysis of Photovoltaic Systems Power Losses in Partial Shading Conditions
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018Photovoltaic (PV) system characteristics are significantly affected by shading conditions and thus the power productivity of the system is subject to vary accordingly. Therefore, this triggers the need for a broad understanding for the power losses caused by partial shading conditions (PSC).

MPPT Algorithm Under Partial Shading Conditions
2012This paper proposes a novel maximum power point tracking (MPPT) algorithm based on analyzing the output characteristics of PV array under uniform irradiance and partial shading conditions (PSC). The algorithm adds partial shadow judging conditions in variable step perturb and observes (P&O) method.

An Algorithm to Detect Partial Shading Conditions in a PV System
Materials Science Forum, 2016Multiple local maxima (MPPs) are presented on the P-V curve of a PV system under partial shading conditions. In general, standard maximum power point tracking (MPPT) algorithms have trouble locating the global maximum, leading often to suboptimal operation at a local MPP, and thus to decreased efficiency.

An approach to increase power in Partial shading condition by reconfiguration
2015 Annual IEEE India Conference (INDICON), 2015Photovoltaic (PV) array output power will be largely effected because of Partial shading Most of the time reduction of output power happens due to mismatch of the voltage and currents of the PV module combination which are considered as mismatch losses. To reduce these losses various reconfiguration techniques have been proposed earlier. The losses are

Experimental Analysis of Photovoltaic Modeling for Partially Shading Conditions
2018 13th IEEE International Conference on Industry Applications (INDUSCON), 2018Predicting the behavior of I-V and P-V curves for photovoltaic (PV) generation is possible through mathematical models for photovoltaic cells. However, current models are made for uniform conditions, making it difficult to analyze in case of non-uniform conditions such as partially shading conditions (PSC).

Distributed MPPT control under partial shading condition
2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016The performance of series connected PV panels significantly limited by the current mismatch caused by the partial shading. Distributed maximum power point tracking can increase the overall efficiency. A module level and a string level sub-module integrated maximum power point trackers are presented in this thesis.

Parameter Enhancement of Solar Array under Partial Shading conditions
2020 IEEE 9th Power India International Conference (PIICON), 2020Partial shading is the major drawback of reducing the output power of PV array. Shade dispersion through Tom-Tom puzzle pattern is proposed in this manuscript to reduce the partial shading effects. The proposed method is compared with standard TCT configuration to test its efficacy.
