Ruiwei Jiang receives NSF funding

IOE Professor Ruiwei Jiang has received NSF funding for his project entitled, "Collaborative Research: Enhancing Power System Resilience via Data-Driven Optimization"| Short Read

As a backbone of the U.S. infrastructure, the electricity grid transmits around 400 billion dollars of electricity across the country every year. This grid is increasingly vulnerable because of more frequent and severe natural disasters, in addition to the long-standing challenges from random equipment failures and operation errors. The evaluation and mitigation of disruption-related risks and impacts are often computationally prohibitive due to random weather conditions, high-dimensional data and decisions, and the combinatorics nature of component failures. This project will derive analytical models and scalable solution methods to assist system operators to better evaluate and mitigate disruptions. The analytical models employ publically available data on meteorology and transmission availability, and the solution methods will be evaluated on test instances with industrially relevant sizes.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
