Novel Detection Method for Consecutive DC Commutation Failure Based on Daubechies Wavelet with 2nd-Order Vanishing Moments

open access: yesEnergies, 2018
Accurate detection and effective control strategy of commutation failure (CF) of high voltage direct current (HVDC) are of great significance for keeping the safe and stable operations of the hybrid power grid.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

A Social Entrepreneurship Perspective of De‐Carbonising the Footprint through Recycling Compensation: A Case Study of the NGO Madre Coraje

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This research analyses the carbon footprint of the NGO Madre Coraje, using an integrated methodology that combines the calculator provided by REAS (Red de Economía Alternativa y Solidaria) Navarra and the Life Cycle Assessment (LCA). It quantifies emissions across the three scopes of the Greenhouse Gas Protocol, evaluating both direct and ...

Stability Bounds for the Generalized Kadanoff‐Baym Ansatz in the Holstein Dimer

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Predicting real‐time dynamics in correlated systems is demanding: exact two‐time Green's function methods are accurate but often too costly, while the Generalized Kadanoff‐Baym Ansatz (GKBA) offers time‐linear propagation at the risk of uncontrolled behavior. We examine when and why GKBA fails in a minimal yet informative setting, the Holstein

Security domain modeling and suppression of commutation failure for LCC-HVDC considering AC-DC coupling

open access: yesEnergy Conversion and Management: X
In line-commuted converter based high voltage direct current (LCC-HVDC), commutation failure (CF) is a main source of danger. The CF is usually suppressed by regulating the single electrical quantity.
