Online dynamic voltage stability assessment method of AC/DC power systems

The Journal of Engineering, 2018
The reactive power absorption of conventional line commutated converter–high-voltage direct current transmission systems challenges on the voltage stability of AC/DC power systems. Many online dynamic voltage stability assessment approaches have been put

Analysis and assessment standards of power stability of multi-send HVDC systems

The Journal of Engineering, 2019
The asynchronously interconnected Yunnan Power Grid is a typical multi-send HVDC system. So far, research on systems with multiple high voltage direct current (HVDC) links is mainly focused on multi-infeed HVDC systems, and the assessment standards for ...

Direct air capture of CO2 and climate stabilization: A model based assessment [PDF]

Climatic Change, 2013
This paper provides a novel assessment of the role of direct air capture of CO2 from ambient air (DAC) on the feasibility of achieving stringent climate stabilization. We use the WITCH energy-economy-climate model to investigate the long term prospects of DAC, implementing a technological specification based on recent estimates by the American Physical

Numerical assessment of the mechanical stability in vertical, directional and horizontal wellbores

International Journal of Mining Science and Technology, 2013
Abstract In this research the stability of wellbore is evaluated in seven different stress regimes and diverse orientations using FLAC3D software. The normalized yielded zone area (NYZA, i.e., the ratio of surrounding yielded cross-sectional area to initial area of wellbore) is determined for different mud pressures as well as diverse orientations of

Second Generation Intact Stability Criteria: on the validation of codes for direct stability assessment in the framework of an example application [PDF]

Polish Maritime Research, 2013
ABSTRACT The Sub-Committee on Stability and Load Lines and on Fishing Vessels Safety (SLF) of the International Maritime Organization (IMO) has undertaken the development of so-called “Second Generation Intact Stability Criteria” (SGISC) with the intention of providing a new set of rules covering those phenomena which are not properly covered by ...
