An Optimal Total Cross Tied Interconnection for Reducing Mismatch Losses in Photovoltaic Arrays

IEEE Transactions on Sustainable Energy, 2013
A mismatch in a photovoltaic array implies differences in the I-V characteristics of the modules forming the array. This can lead to significant energy losses known as mismatch losses. The mismatch and the resulting losses can be reduced by altering the interconnection of the array. This paper proposes an optimal total cross tied interconnection, based

Experimental investigation of serial parallel and total-cross-tied configuration photovoltaic under partial shading conditions

2017 International Conference on Sustainable Energy Engineering and Application (ICSEEA), 2017
One of issues about array photovoltaic (PV) is partial shading conditions. It can cause mismatch between the modules, leading to undesirable effects such as reduction in power generated and hot spots. Partial shading is caused by passing clouds, tree shadows, nearby building, tower, poles, etc. So the power output is less than expected value. It is not

Effects of shading on current, voltage and power output of total cross-tied photovoltaic array configuration

TENCON 2015 - 2015 IEEE Region 10 Conference, 2015
The Philippines, being a tropical country, has a high photovoltaic (PV) energy generation potential that can help meet demand due to impending power supply shortage in the coming years. One factor that limits solar PV generation is nonuniform illumination or partial shading.

PV Distributed-MPP Tracking: Total-Cross-Tied Configuration of String-Integrated-Converters to Extract the Maximum Power Under Various PSCs

IEEE Systems Journal, 2020
The building integrated photovoltaic (PV) central inverter architecture comprises various PV module configurations. The PV module configurations are vulnerable to shading effects and cause mismatching power losses. To reduce the detrimental impact of shading and mismatching on energy production, the PV distributed-maximum power point tracking (D-MPPT ...

Mathematical analysis of total-cross-tied photovoltaic array under partial shading condition and its comparison with other configurations

Solar Energy, 2016
Abstract The goal of this paper is to investigate total-cross-tied (TCT) configuration under partial shading condition. A full investigation requires mathematical analysis and simulation. An accurate mathematical analysis gives us a better understanding of how partial shading affects the output curves of the solar cell, so we first mathematically ...

Shade Resilient Total Cross Tied Configurations to Enhance Energy Yield of Photovoltaic Array Under Partial Shaded Conditions

Emerging Trends in Computing and Expert Technology, 2019
Partial shading restrains the output of photovoltaic (PV) system, as mismatch losses are prominent when shade dispersion is uneven in an array. Partial shading (PS) is unavoidable in residential installations and it is therefore essential to improve the output under such conditions.
