Smart-ISO model looks at energy grid Science Contributor
The essence of predicting uncertainty, said Professor of Operations Research and Financial Engineering Warren Powell, is truly governed by “making a decision now before I know things.” Powell, along with a team at Princeton and a team at the University of Delaware, was tasked by grid operator PJM Interconnection to create a model simulating how their power grid would respond after supplying it with wind from offshore sites. The interest started with the deregulation of freight transportation in the ‘80s, Powell remarked, and how it led to the quick necessity for optimizing trucking routes along the country. This soon turned into optimizing not vehicles but energy, “something different and more current,” according to Powell. Powell and his team were responsible for creating Smart-ISO, a stochastic model for the mid-Atlantic states which handles variability and uncertainty to a remarkable extent. After receiving grant money from SAP, Powell and others began building his “big battleship of a model” in order to pursue modeling unpredictable variables within the grid environment. Pow-
ell and his team were soon contacted by a team at UD to investigate the effects of offshore wind injection into the PJM grid itself. “We built this model, carefully calibrating it, and then using it to ask what exactly happens when there is offshore wind,” Powell said about the building process. According to Powell, SmartISO further examines the grid system, suggesting the most cost effective way to distribute energy throughout the states. He explained that there are problems which need direct attention from Smart-ISO. According to Powell, because the steam inside the steam generators cannot instantly be created, steam generators all have to be prepared a day in advance. This, noted Powell, makes for energy distribution within the grid quite a tricky endeavor. SmartISO maneuvers around this difficulty by suggesting which specific generators get switched on and off a day in advance. According to Powell’s, his team’s model shines in its use of controlling the grid’s energy reserves. Powell explained there are means in which reserve fossil turbines can be activated to provide more enSee WIND page 2

The 17th annual Vagina Monologues are a series of vignettes performed by Princeton students that reflect the diverse expeiences of womanhood.
The Vagina Monologues By Rose Gilbert Contributor
From interpretive dances to think pieces to social experiments, the annual on-campus performances of Eve Ensler’s Vagina Monologues has always generated plentiful feedback from University students. The episodic play, which consists of an unfixed number of monologues performed by an unfixed number of women, was first performed in 1996 at the HERE Arts Center in New York City. It made its way to the the University in 2001. The content of these monologues - which focuses on women’s experiences and relationships with their bodies — has always been controversial. Nevertheless, this year’s seventeenth consecutive perfor-

Carney lectures on halftruths and fake news In a critique of The New York Times’ new motto “The truth is more important now than ever,” Tim Carney contends that the truth matters now more than it did from January 2009 to January 2017. “In other words, the truth matters less before Donald Trump was president,” Carney said, noting that he was being “very semantic.”

she learned about the history of the Monologues as a freshman. She was in the production her freshman and sophomore years. She has also acted in productions of “I Was There In The Room” and “My Vagina Was My Village.” “I knew that [the play] was a feminist piece and that of course it had to do with vaginas,” she said. “I knew it was blunt and graphic and honest. I read the script and found out that it was about many other things including womanhood, motherhood, growing up, joy, healing, and self-discovery.” Desrogène explained that she believes the play’s enduring resonance might be due to its adaptability as a work of art.

mance of the play at the University evidences that it has indeed stood the test of time. Romie Desrogène ‘17, one of this year’s show’s co-directors, who first saw the Vagina Monologues when she was eleven years old, said that the play’s “radical” content had always fascinated her. “I knew it [the play] was about vaginas and the fact that it was played in Haiti — a place where they were even more of a taboo — made the play seem even more radical to me. I could not wait to grow up and be part in of it, even though I had not even seen the play yet,” Desrogène said. “You can say I was pretty psyched to be in [the play] freshman and junior year, and then directing it this year after a seven-year wait.” Desrogène explained that

Six University professors have been named Sloan Research Fellows for 2017. The Sloan Research Fellowships are two-year, $60,000 fellowships awarded to researchers by the Alfred P. Sloan Foundation “in recognition of distinguished performance and a unique potential to make substantial contributions to their field”. Past University affiliated recipients include John Nash and Richard Feynman, both of whom went on to win Nobel Prizes in their respective fields. According to the foundation website, 226 University affiliated individuals have received the Sloan Fellowship as of 2017. This year’s recipients are Dr. Amir Ali Ahmadi, assistant professor in the Department of Operations Research and Financial Engineering; Dr. Han Liu, also an assistant professor in the ORFE department; Dr. Nicholas Sheridan, assistant professor in mathematics; Dr. Nathalie de Leon, assistant professor in electrical engineering; Dr. Matthew Kunz, assistant professor of astrophysical sciences; and Dr. Silviu Pufu, professor of physics. Ahmadi’s line of research focuses on the “intersection of optimization and computer science.” The specific problems that he addresses in his work are polynomial optimization problems. “It’s quite tricky to understand which subclasses can be solved with computers and algorithms,” Ahmadi said. “A lot of my work is to draw this boundary.” One practical application of poly-
nomial optimization problems specifically includes finding optimal locations for buildings. Although Ahmadi is affiliated with the ORFE department, he received a fellowship in computer science for the lack of a specific category dedicated to ORFE. He expressed gratitude that “people outside of [his] immediate field also recognized [his] work as of high quality and importance.” Kunz expressed honor at being named a recipient of the fellowship. Kunz received the fellowship for his work in astrophysics. Some of the problems that he and the students he oversees are working on include “why astrophysical systems have the magnetic field strengths that they do and investigating turbulence in solar winds,” according to Kunz. He noted that one of the best aspects of the Sloan Fellowship is that the usage of money is not as restricted as it can be with other grants. “The Sloan Fellowship doesn’t fund one project directly, but enables flexibility in each one of them,” Kunz said. He noted the example of purchasing a powerful computer needed for simulations that might otherwise not be approved for purchase. De Leon’s research group focuses on materials science, an interdisciplinary field that brings together chemists, chemical engineers, physicists and electrical engineers in her lab. De Leon said her broad research program is working on quantum technology with color centers in diamonds. “Working in this category involves a lot of surface science and

materials chemistry, but on the other side of it there’s a lot of optics and quantum control techniques for learning how to control and manipulate these color centers,” she said. Sheridan’s research in mathematics focuses on two types of geometry: “algebraic geometry, which has a long history going back to the Greeks’ work on conic sections; and symplectic geometry, which has its origins in celestial mechanics.” With his work, Sheridan hopes to answer difficult questions about symplectic geometry “by translating them into easier questions about algebraic geometry.” In an email, Sheridan said that he is “very honored and excited” about the fellowship and said he immediately “Skyped with [his] parents back in Australia to tell them.” Liu is affiliated with the Statistical Machine Learning Lab. Liu’s work focuses on a developing new field of theoretical science within called combinatorial interference, which studies both “informational complexity (amount of data) and computational complexity (running time).” In an email, he said that “success on this research will lead to a new generation of high impact applications, including computational neuroscience, genomics, finance, and social networks”. Pufu is an assistant professor in the physics department whose work focuses on the field of high energy theory. He received his undergraduate degree in physics from the University in 2007 and his Ph.D degree in 2011. Pufu did not respond to request for comment.
