Graduate Students

I’m seeking graduate students motivated in energy system modeling, optimization, and market designs. If you are interested working with me, please apply through Columbia admission system and email me a copy of your CV.

Research

My research proposes algorithms and market designs towards an economic, reliable, and sustainable power system. I’m particularly interested in the following topics.

A Future with Energy Storage

Energy storage offsets renewable fluctuations and is the key to a low-carbon future, but managing these assets at the system level remains an open question. Operators must make real-time dispatch decisions to mitigate instantaneous imbalances, but also need to consider the value of stored energy in the future. Shaping future insights into a computation-viable form is a challenge that requires efficient operation algorithms and advanced data analytic tools.

Individuals in the System

A power system is more than a physical infrastructure, it interconnects millions of individuals with different roles and objectives. A household with roof-top PV is both a consumer and a producer, but might not be an active market participant. Merchants like energy storage and financial entities are neither consumer nor producer, but they contribute flexibilities and liquidities that aid power system operations. Analyzing individual objectives and looping their behavior into the system design is of great importance.

Re-imagining Power System

With more inertia-free and distributed resources, the power system is transforming from a centralized sequential-stage scheme into a hierarchical structure with autonomous local agents and aggregations. This transformation poses a series of interesting research questions such as designing new market flexibility products and interfacing local aggregations with the wholesale market.

Biography

I traveled many places during my career and am fortunate to have worked with many great researchers. I have arranged my experience based on the cities I lived.

Shanghai

I obtained my BS degree in ECE from SJTU in August 2011.

Ann Arbor

I was in UM, Ann Arbor from September 2009 to January 2011 as part of a joint dual-degree program.

Zurich

I started my master on power systems and power electronics in ETH Zurich in September 2011 and received my master degree in Electrical Engineering in February 2014.

Dättwil

During my study at ETH I was a research intern at ABB Corporate Research Center in Baden-Dättwil. where I worked with Marija Zima-Bockarjova on an active demand project.

I continued my master thesis at ABB with Alexandre Oudalov and Andreas Ulbig, my thesis on battery energy storage was examined by Göran Andersson.

Beijing

I spent my 2014 summer in Beijing as a research intern in China Electric Power Research Institute where I worked on wave power generation. .

Seattle

From September 2014 to June 2018 I was a PhD student at UW advised by Daniel Kirschen and Baosen Zhang.

I interned at Doosan Gridtech during the summer of 2017 where I worked on several industry projects on battery energy storage and market analysis.

Holyoke

I was a research intern in ISO New England in the summer of 2016. I worked with Jinye Zhao, Tongxin Zheng, and Eugene Litvinov on modeling energy storage in energy markets.

Cambridge

I moved to MIT as a postdoctoral associate in August 2018. I worked with Audun Botterud, Francis O’Sullivan, and Magnus Korpås on energy storage and electricity markets.

New York

I will join Columbia University as an Assistant Professor in January 2020.
