Distributed MPPT control under partial shading condition

2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016
The 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.

Automatic PV Array Reconfiguration under Partial Shading Conditions

NTU Journal of Renewable Energy, 2023
Photovoltaic (PV) arrays have been recognized as one of the main clean renewable sources of electrical energy. In practice, PV arrays are subject to unavoidable non-uniform partial shading (PS) due to clouds, buildings, dust, etc. PS causes the hot spot problem, mismatch losses, and output power degradation.

Exploration of partial shading condition in photovoltaic array

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017
Photovoltaic (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.

Parameter Enhancement of Solar Array under Partial Shading conditions

2020 IEEE 9th Power India International Conference (PIICON), 2020
Partial 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.

MPPT for a photovoltaic system under partial shaded conditions

2020 IEEE International Conference on Industrial Technology (ICIT), 2020
In this paper, a method to find the maximum power point for a photovoltaic system under partial shaded conditions is presented. Furthermore, a control law using Passivity Based Control is proposed for a DC-DC converter. In addition, simulation results show the good performance of the extremum seeking control in searching the global maximum based in the
