Analyzing and Mitigating the Impacts of Grid-edge Technologies on Power Distribution Networks

Date: August 2, 2023 (WED) Time: 2p.m. to 4p.m. Venue: CF617 Speaker: Antoine LESAGE-LANDRY (Assistant Professor in the Department of Electrical Engineering at Polytechnique Montréal, QC, Canada)   Abstract In this talk, we first present a new rapid estimation method (REM) to perform stochastic impact analysis of grid-edge technologies (GETs) to the power distribution networks. The evolution of network states' probability density functions (PDFs) in terms of GET penetration levels are characterized by the Fokker-Planck equation. The approach is illustrated on a large-scale, realistic distribution network using a modified version of the IEEE 8500 feeder, where electric vehicles (EVs) or photovoltaic systems are installed at various penetration rates. Second, we design an incentive-based mitigation strategy for equipment overloading leveraging the REM. The objective is to shift the EV charging during the peak hours when the equipment is overloaded to the off-peak hours and maintain equipment service lifetime. The incentive level and corresponding contributions from customers to alter their EV charging habits are determined by a search algorithm with provable convergence guarantee. The strategy is illustrated on the same IEEE 8500 feeder with a high EV penetration to mitigate overloads on the substation transformer.   Biography Antoine Lesage-Landry is an Assistant Professor in the Department of Electrical Engineering at Polytechnique Montréal, QC, Canada.

Joint Seminar with RISE

Launched in 2010, Nature Communications is the flagship open access journal from Nature Portfolio dedicated to publishing significant advances in each field in a multidisciplinary venue across all areas of science and technology. In this talk, I will introduce the journal with its aim and scope and give an overview of the editorial and peer-review process and what editors look for in a manuscript. I will provide tips on how to write a convincing cover letter, abstract and paper and how to prepare your manuscript for submission. This talk will also cover the recent trends and developments in scientific publishing including new forms of peer review and reporting of data, in addition to some possible misconceptions towards the journal and suggestions on how to prepare yourself for scientific publishing.

Distributed Fiber Optic Sensing over Deployed Optical Fiber Cables: Recent Research and Applications

The optical fiber network is the backbone of modern telecommunications infrastructure. There is currently an estimated 5 billion km of deployed fibers worldwide, crisscross the world’s oceans, and forming dense networks around major metropolitan areas. In addition to their intended purpose of facilitating telecommunications, optical fibers can also be used as sensors to monitor the ambient environment. Distributed fiber optic sensing (DFOS) exploit the scattering mechanisms in glass – Rayleigh, Brilluoin and Raman scattering – that are sensitive to strain and/or temperature. Furthermore, any environmental parameter that can be transduced to strain or temperature can also be sensed by DFOS. DFOS can help facilitate public safety and smarter cities, and can support research in areas such as ocean bottom seismography. DFOS has been around since the 1970s. Recently, this field has been revolutionised by technologies originally developed for telecommunications, including coherent detection, digital signal processing, coding, and spatial/frequency diversity, which can improve performance in terms of measurand resolution, reach, spatial resolution and bandwidth. Combining DFOS with machine learning methods, it is possible to realize complete sensing systems that are compact, low-cost, and can operate in harsh environments. In this talk, I will review Rayleigh-based DFOS methods, and provide insight into recent research results in this field, and examples of DFOS applications over deployed fibers.
