Grid mixers and power grid oscillators
1994Power-combining schemes involving planar grids of solid-state devices quasi-optically coupled in free space are an efficient means of combining power at microwave and millimeter-wave frequencies. The quasi-optical coupling of these grid circuits makes them ideal for millimeter-wave and submillimeter-wave applications by eliminating waveguide sidewall ...

A Machine Learning Approach to Detection of Geomagnetically Induced Currents in Power Grids
IEEE transactions on industry applications, 2020Geomagnetically induced currents (GICs) in power grids are mainly caused by geomagnetic disturbances especially during solar storms. Such currents can potentially cause negative impacts on power grid equipment and even damage the power transformers ...

Power grid fault diagnosis considering on grid-connected wind power
2013 IEEE Grenoble Conference, 2013The effects that wind power brought on power system protective configuration is analyzed, and the protective allocation of all electrical components when doubly-fed wind turbines connected to power grid is elaborated. Based on analysis of network connection in China, the basic mode of grid framework change during faults has been analyzed and concrete ...

Fast Screening of Vulnerable Transmission Lines in Power Grids: A PageRank-Based Approach
IEEE Transactions on Smart Grid, 2019In power system operation, there are usually a few vulnerable lines (VLs) which are prone to exacerbate the propagation of cascading failures and lead to severe blackouts with high probability.

Vulnerability Assessment of Power Grids Against Link-Based Attacks
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2020In modern power grids, a local failure or attack can trigger catastrophic cascading failures, which makes it challenging to assess the attack vulnerability of power grids. In this brief, we define the optimal $K$ -link attack problem and study the attack

Environmental Philosophy, 2018
The word “power” tends toward divergent formations, and this paper is prompted by the intersection of two of them. The first form taken up here is power as control, while the second form is material power as fuel. The typical modern configuration of the first form implies an understanding of the second form as subordinate. But what I argue here is that

Energy technology plays a central role in societal economic and social development. Fossil fuel-based technologies have advanced our quality of life, but at the same time, these advancements have come at a very high price. Fossil fuel sources of energy are the primary cause of environmental pollution and degradation; they have irreversibly destroyed ...
