Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Connection of inverters to a weak grid

2000 IEEE 31st Annual Power Electronics Specialists Conference. Conference Proceedings (Cat. No.00CH37018), 2002
Connection of an inverter to export power to the mains for a stiff supply is well understood. This paper examines the dynamics of power export to a weak grid. In this case the local bus angle changes for changes in export power which interferes with the process of synthesizing the inverter voltage.

A control strategy for a solar grid-connected inverter

2013 26th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2013
In this paper, the control of a grid-connected inverter is investigated. There are two key control issues that need to be examined. The first is the control of the AC side of the converter to ensure that sinusoidal output waveforms are produced and that the DC bus capacitor voltage that the six-switch bridge see is fixed.
