AI & ML seminar at Stanford Feb. 24, News

Seminar at Bits & Watts (Stanford) on Machine Learning & AI for Power Systems

January 2022

I am very excited with Dr. Liang Min‘s invitation to present my Smart Grid works on power system control with machine learning and artificial intelligence in the framework of the Bits & Watts Initiative at Stanford! The seminar will take place on Feb. 24th and I will go over the use of top-down heuristically inducted binary decision trees to procure firm capacity by renewables with volatility, and on how voltage control can be modeled as a problem of classical mechanics physics. I look forward to hearing attendees’ ideas and thoughts on other machine learning and AI applications in power system optimization, planning and control.

The seminar will be in-person, so if you are faculty, student & researcher at Stanford and would like us to meet before/after the seminar, please, do not hesitate to reach out!

Active Distribution Seminar at Texas A&M, News

Seminar at Texas A&M on Active Distribution Grids

December 2021

On Friday January 28th, 2022 I will be heading out to Texas A&M to offer a seminar to the Power & Energy Group at the Dept. of Electrical & Computer Engineering. I want to thank Prof. Mladen Kezunovic for the kind invitation and Dr. Birchfield for organizing the seminar. I am excited to talk about how smart grid control and digital twins can enable distribution systems to host greater capacities of renewables, while improving customers’ service by reducing interruption times.

If you are going to be attending or are in the area and want us to talk, reach out to arrange some meeting on that day/afternoon.

AC OPF approximations seminar at Princeton, News

Seminar at Princeton on Linear Approximations to the Optimal Power Flow

November 2021

On Thursday November 4th I had the immense honor to present one of my works at the department of Operations Research and Financial Engineering at Princeton University. Ronnie Sircar kindly invited me and I thank him deeply for that! The presentation was on one of my latest research studies about the linear approximations to the AC Optimal Power Flow and on a method to determine which approximations best fit across a given grid and a loading profile.

During my visit I had the opportunity to make new friends from multiple departments and I want to thank everyone at Princeton for their kindness and hospitality!

Active distribution seminar at NYU, News

Seminar at NYU on Active Distribution Grids

October 2021

I am very grateful to Dr. Yury Dvorkin for honoring me with an invitation to offer an ECE seminar at the Tandon School of Engineering at NYU coming Thursday Oct. 28th! I will talk about how our interest in distribution systems has been revived and, especially, in the challenges these networks face on a daily basis. I will point out the deep-rooted technical issues that remain unresolved when operating a distribution grid and the problematic incentives that have failed to make all end-customers more active within them. The digital twin of distribution transformers for detecting grid faults and the value proposition of hybrid photovoltaic-battery systems behind the meter of residential end-customers are two of the proposals I will discuss to address the aforementioned concerns.

The seminar will be held remotely, but if you are NYU faculty, researcher or student, feel free to reach out to arrange some online meeting on that day/afternoon.

Inverter Interfaced Renewables Seminar at Yale Oct. 13, News

Seminar at Yale on Inverter Control for Grids Rich in Renewables

October 2021

I am extremely lucky to have recently met and exchanged ideas and research aspirations with Prof. Leandros Tassiulas, chair of Electrical Engineering (EE) at Yale.  He has honored me with an invitation to offer a seminar to the Dept. of EE and the Institute for Network Science at Yale on October 13th. I will be presenting 2 of my earlier research works on control methods to procure active power reserves from wind generators and string photovoltaic inverters. Even though these technologies typically pursue maximum use of their aerodynamic and solar potential, respectively, they must also be able to support system stability. This becomes even more critical as renewable resources slowly dominate the grid and displace conventional resources that have until recently ensured stability. I will extend my previous results into the most recent research aspirations for a grid dominated by inverter-interfaced renewables and batteries and how such aspirations may be made possible.

The seminar will be virtual, but I will make myself available to all faculty, students & researchers at Yale, who would like us to talk before/after the seminar, so, please, do not hesitate to reach out!

AI & ML seminar at RPI Sep. 29, News

Seminar at RPI on Power System Control with Machine Learning & Artificial Intelligence

August 2021

I want to thank Prof. Mona Mostafa Hella and Dr. Luigi Vanfretti, my friend and collaborator at the North American Synchrophasor Initiative (NASPI), for inviting me to offer a seminar at the Dept. of Electrical, Computer & Systems Engineering at the Rensselaer Polytechnic Institute on September 29th. I will review 2 of my works on generation control with machine learning (ML) and artificial intelligence (AI). I will start by discussing how to use top-down heuristically inducted binary decision trees of ML to actively control firm capacity by volatile resources operated (among others units) as a Virtual Power Plant. In the second part, I will present how voltage control can be modeled as a problem of classical mechanics physics; from there it can be solved as an AI implementation of the 2nd law of thermodynamics to redispatch active and reactive power generation. I plan to spark a discussion on conceiving new ML applications and AI models for power system operational control and monitoring.

The seminar will be virtual, but I will make myself available to all faculty, students & researchers of RPI, who would like us to talk before/after the seminar, so, please, do not hesitate to reach out!

News, PV-BSS seminar at OSU Nov. 10

Seminar at Ohio State University on residential PV & batteries

August 2021

I am grateful to my friend and collaborator at the IET Renewable Power Generation journal, Prof. Ramteen Sioshansi for kindly inviting me to offer a seminar at the Dept. of Integrated Systems Engineering at Ohio State University on November 10. I will talk about my earlier work at CMU on the Dept. of Energy SHINES project, on how batteries can allow residential end-customers to widely benefit from behind-the-meter photovoltaics. Reducing the costly effects of demand charges promises additional value to that of net-metering or self-consumption from photovoltaics, while the policy implications offer much food for thought on the role of utilities, cooperatives and/or microgrids.

Depending on the situation with COVID the seminar might be in-person, so follow me on Twitter & LinkedIn for updates.
