January 2022A few months ago, my work with Omid Mousavi from DEPsys SA on the Digital Twin of the Medium Voltage side of a Distribution Transformer based on Low Voltage side measurements was published in the IEEE Transactions on Power Delivery (preprint). I have been getting numerous hits on that paper plus some invitations for collaboration, so I thought I should blog a few thoughts about the subject a bit more broadly.Let me start by describing the idea of this specific publication first. We want to monitor harmonics and system faults with adequate accuracy and, preferably, in… Read More »
January 2022I 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… Read More »
December 2021On 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… Read More »
November 2021It might have started more than a year ago, but I have still not found the words to describe my immense excitement and my unwavering enthusiasm for my research collaboration with X, the moonshot factory of Google! Last April, Astro Teller (X’s Captain of Moonshots) and Audrey Zibelman (X’s VP & previously AEMO‘s CEO), blogged here and here, respectively, about why the decarbonization of the electrical grid needs a moonshot. By developing the digital twin of the grid, the Tapestry moonshot aims to enable power system monitoring at unprecedented granularity and… Read More »
November 2021On 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… Read More »
October 2021I 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… Read More »

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,… Read More »
September 2021I am humbled by Prof. Wu‘s invitation to offer a Research Seminar at the Dept. of Electrical and Computer Engineering at Stevens Institute of Technology on November 17th. I will be discussing the criticalities in the operation, maintenance and development of the distribution systems in electrical grids. Even though widespread black-outs are infrequent, customers in the US and elsewhere still suffer service interruptions that add up to many hours per year. The reasons lie in the poor monitoring of the distribution system, the limited use cases for distributed… Read More »
August 2021I 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… Read More »
