Pre-Commercial Demonstration of a Direct Non-Iterative State Estimator

The conference paper that I presented at the 2018 IEEE PES T&D Expo in Denver has been published online, and I’m happy to share it here. This paper is related to the non-iterative state estimation method that I’ve worked on during my grad school and at my current job, so I did put a lot of time and effort for the method to get to this point. As usual, this paper is probably only interesting to those in the electric power industry, in particular to those who are interested in synchrophasor applications. Read below for the abstract and link to the full paper.

Real-time Voltage Instability Indicator (RVII): Enhancements and Case Studies

For the first time in almost 3 years, I have a new technical paper to share on this blog. The paper was written for a conference, and it talks about a measurement-based voltage instability detection method that I worked on as part of my job. It might be an interesting read for those in the electric power industry, especially those who deal with real-time operation and monitoring. This is the first paper that I (co)authored as part of my current job and my professional career, and I’m glad it finally got published. Read below for the abstract and link to the full paper.

A synchrophasor measurement based method for assessing damping torque contributions from power system stabilizers

A conference paper that I’ve worked on as part of my PhD research has finally been published, so I shared it here for all you power systems aficionados out there. The paper is about a new method for assessing the damping torque contributions from power system stabilizers. If you understand every word in the title, then it’ll be of interest to you. If not… well it might be interesting too. Anyways, this papers was presented at the IEEE PowerTech 2015 conference in Eindhoven, the Netherlands in July. I didn’t get to go to the Netherlands for the conference, but at least I have another entry in my (short and unremarkable) publications list. Read below for the abstract and link to the full paper.

Power System State Estimation using a Direct Non-Iterative Method

Today I share a paper that I’ve been working on for the last 3 years. This is the first research journal paper that I’ve ever published, so it is a personal milestone. I post it here just to show that my PhD studies weren’t completely unproductive, given how most PhD students usually have a few journal papers on their CV when they graduate. The topic of this paper is the major topic in PhD dissertation, and I also have an earlier conference paper on this topic. It’s been a long time coming for this paper, and I’m glad we finally got the paper published. Hopefully I’ll have a few more publication as I continue to work in the power industry. Read below for the abstract and link to access the full paper.

A Low-Rank Matrix Approach for the Analysis of Large Amounts of Power System Synchrophasor Data

I was randomly looking at my Google Scholar account and saw that a conference paper with my name got published, and so I’m sharing the paper on my website. The paper was for the 48th Hawaii International Conference on System Sciences, and it’s something that I worked on when I was still at RPI. I only helped with a section of the paper, and hence my name is pretty far down the author’s list. Still, it’s never a bad thing to have more items to put on my publications list, and a sincere thank you to my talented co-authors for their hard work. The topics covered in this paper is actually something that I find very interesting. The ever larger amounts of power systems data produced by synchrophasor devices produces problems for analysis and storage, and the ideas outlined in this paper have potential in alleviating these issues. Read below for the abstract and link to the full paper from the conference website.

A Non-Iterative Method for Power System State Estimation and A PMU-Based Method for Assessing Generator Damping Contributions

I received my PhD degree in May of this year, but it took a couple of months for my dissertation to become available in RPI’s digital collections, so that’s why I haven’t posted the abstract here until now. Unlike my Master thesis, my PhD dissertation actually has a respectable number of pages (130 including all front and back matter). The dissertation features work on two not-very-closely related projects, and that’s why the title is a mouthful. I put 3 years of work into my dissertation. There are things I wish I could have accomplished in my dissertation, but I’m proud of what I was able to finish. And of course, I’m just happy that I was able to graduate with this dissertation. Obviously I don’t expect anybody to try to buy a copy from ProQuest and read the whole thing, but if you are really into power systems research, my dissertation may prove to be an interesting read :wink: .

Improving performance of the non-iterative direct state estimation method

I’m posting my theses and research papers from the grad school career on this site. This paper is the first paper I wrote that made in into IEEE’s IEEE Xplore digital library. It’s only a conference paper, but I’m happy it was included into IEEE Xplore. I still don’t have a journal paper to show for my grad school career, but hopefully that’ll change soon. Anyways, read below for the abstract and the link to the IEEE Xplore entry for the full paper.

A Linux-based, Flexible Phasor Data Concentrator Design

Now that I have finished grad school, I am posting my Master thesis on this blog since this blog is a collection of my works, even scholarly ones. At around 45 pages including front and back matter, my thesis is quite short by thesis standards, but it’s still too long to post on this blog, so I’ll only post the abstract and how it can be accessed from my grad school Rensselaer Polytechnic Institute. If you don’t know what a phasor data concentrator is, that’s okay. Most people don’t know either. My thesis is a long read that’ll only interest a small number of people in the power systems area. Read on to find out the details.
