Simulated Impact of Shortened Strings in Commercial and Utility-Scale Photovoltaic Arrays

open access: yesEnergies, 2023
The deliberate removal of photovoltaic modules from a string can occur for various reasons encompassing maintenance, measurements, theft, or failure, reducing that string length relative to others when replacement modules are not available and there are ...

Investigation of the current density’s non-uniform distribution in dead-end PEMFC with multi-zone measurement methods

open access: yesEnergy Conversion and Management: X, 2023
Uneven current density distribution in a proton exchange membrane fuel cell (PEMFC) can decrease the reactant and catalyst utilization, reduce the energy conversion efficiency of the whole fuel cell, and even lead to a shortened cell life.

Towards recovery of complex shapes in meshes using digital images for reverse engineering applications [PDF]

open access: yes, 2010
When an object owns complex shapes, or when its outer surfaces are simply inaccessible, some of its parts may not be captured during its reverse engineering. These deficiencies in the point cloud result in a set of holes in the reconstructed mesh.

Feasible protection strategy for HVDC system by means of SFCL and passive resonance DC breaker

open access: yesThe Journal of Engineering, 2019
The key obstacle in implementing high-voltage direct current (HVDC) grid, which is considered as the future of power grid, is the absence of effective DC circuit breaker (DCCB). At present, HVDC grid could be based on half-bridge (HB) or full-bridge (FB)
