A Reconfiguration Method for Extracting Maximum Power from Non-Uniform Aging Solar Panels [PDF]
Energies, 2018 Aging affects different photovoltaic (PV) modules in a PV array in a non-uniform way, thereby leading to non-uniform working conditions of the PV modules and resulting in variations in the power outputs of the PV array.

Evaluation of Non-Uniform Thermal Aging of XLPE Cable Based on Modified Debye Model
Frontiers in Materials, 2022 The polarization/depolarization curve (PDC), which contains abundant insulation information, is widely used to evaluate the insulation condition of the cross-linked polyethylene (XLPE) cables. However, the insulation condition assessing the result of the

A modified XY model of transformer oil–paper insulation system including non‐uniform aging and conductance effect [PDF]
IET Generation, Transmission & Distribution, 2021 The accuracy and feasibility of the traditional XY model of transformer oil–paper insulation system are disputable since it ignored the effect of non‐uniform aging and conductance on dielectric response property.

Inducing Non-uniform FPGA Aging Using Configuration-based Short Circuits [PDF]
ACM Transactions on Reconfigurable Technology and Systems, 2022 This work demonstrates a novel method of accelerating FPGA aging by configuring FPGAs to implement thousands of short circuits, resulting in high on-chip currents and temperatures. Patterns of ring oscillators are placed across the chip and are used to characterize the operating frequency of the FPGA fabric.

Non-Uniform Aged Modules Reconfiguration for Large-Scale PV Array [PDF]
IEEE Transactions on Device and Materials Reliability, 2017 In the past decades, a large number of photovoltaic (PV) plants have been built. Due to the minor physical differences between PV cells and the influence of environmental factors such as rains, temperature, and humidity, the aging of a PV array is often distributed unevenly within each PV module.
