Thursday, 19 May 2022 (10:00 AM ET): "Design of Robust Cyber Shield for a Grid-Connected PV System via Digital Watermarking Principle" by Prasad Enjeti, Texas A & M, USA
Abstract: This IEEE PELS Webinar presents of an active defense mechanism for detecting cyber-attacks on sensors controlling a grid-tied PV system. Several possible cyber vulnerabilities in Grid tied PV Systems are discussed. The defense mechanism introduces a private (secret) watermarking signal into the control inputs of the grid-tied inverter system. This will enable the detection of any malicious manipulation of sensor measurements such as data measured via smart meters used to control the inverter. Based on the measured data, and system identification model two statistical tests are conducted to identify anomalies in the system using the presence of the watermarking signal. It shown that when sensor data is compromised and/or replaced by a pre-recorded healthy signal, both test 1 and 2 exhibit high values indicating a possible malicious activity. As an added benefit, the proposed approach can also identify/alert when sensors malfunction. The robustness of the proposed algorithm is tested and validated with several attack scenarios on a grid tied PV system. Select results from an experimental setup are discussed.
Biography: Prasad N. Enjeti (M'85-SM’88-F'00) received his B.E. degree from Osmania University, Hyderabad, India, in 1980, the M.Tech degree from Indian Institute of Technology, Kanpur, in 1982, and Ph.D. degree from Concordia University, Montreal, Canada, in 1988, all in Electrical Engineering. He has been a member of Texas A&M University faculty since 1988 and is widely acknowledged to be a distinguished teacher, scholar and researcher. He holds the Texas Instruments (TI) Jack Kilby Chair. His primary research interests are in advancing power electronic converter designs to address complex power management issues. His recent research focus has been on innovative power electronic solutions to interface renewable energy sources to electric utility and to enhance cybersecurity of industrial systems. To date he has graduated 35 PhD and 53 MS students. Fourteen of his PhD students currently serve as faculty in institutions at home and across the world while others have leadership positions in industry. He along with his students have over 100 journal publications and received numerous best paper awards from the IEEE. Among the many honors he has received are the IEEE Fellow Award in 2000, Texas A&M University Association of Former Students University Level teaching award in 2001, R. David Middlebrook Technical Achievement Award from the IEEE Power Electronics Society in 2012 and IEEE IAS Distinguished Achievement Award 2021.
Tuesday, 7 June 2022 (8:00 AM ET): "Automated PCB Component Placement and Copper Trace Layout for Power Electronics" by Gus Zhang, Univ. of Manchester, Manchester, UK
Abstract: Almost all power electronics PCBs are still manually laid despite the “auto-routing” and “auto-placement” functions in CAD software are available many years ago. It is also a time and material consuming process that often requires experienced engineers to take iterations of development testing stages before the PCB design goes to mass production. We have been looking into generating the PCB layouts in an automated way and optimising for energy efficiency and density, thermal distributions, and other aspects. This will potentially help the industry to build tailor-made power converters suiting individual applications. Technically, the main difficulties are the unrestricted degree of freedom on both the solution space and versatile objectives. In this webinar, the feasibility and effectiveness considerations on algorithms and data structure in computer programming of automated PCB design will be discussed, and an in-progress open-source project PEPCB will be introduced. Examples of programme generated PCBs will be demonstrated.
