I would like to update you about some of my recent publications with great colleagues on particularly interesting topics.
Starting from the latest one, 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. The proposal, practically, eliminates the requirements for costly medium voltage side instrument transformers, that also require network disruptions to be installed. Harmonics and system faults are captured with remarkable accuracy! You can find a preprint here.
Guannan He‘s & Rebecca Ciez‘s revolutionary idea about redefining the end of life of battery storage systems based on their use value was published in the Applied Energy journal of Elsevier and can be found here. The study argues that value drawn from a specific use of a battery might be turning negative earlier than the technical/chemical end of life of the battery. With this in mind, the battery may be repurposed to other uses that will be profitable making best use of its lifetime. I am delighted to have collaborated in this work!
There are also two conference papers from 2020 IEEE International Conference on Environment and Electrical Engineering and 2020 IEEE Industrial and Commercial Power Systems Europe (EEEIC/I&CPS Europe), which I was honored to be invited to submit them as IEEE IAS journal publications as well! The first one is my work with Soummya Kar from CMU ECE on Assessing the effect of linear approximations to the Optimal Power Flow (OPF) accuracy and performance, considering the adequate modeling of line resistances. In the picture above we demonstrate how accounting for line resistances (especially important for distribution systems) can improve the approximation of the voltage angles in OPF.
The second one again with Omid Mousavi from DEPsys SA discusses the different Monitoring Requirements for the Realization of State Estimation at Distribution Systems and you can access it here.
