Upcoming Webinars 

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

Register


           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.

 Prasad Enjeti 2019      
 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.

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

Register

          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.

GusZhang          Biography: Dr Cheng Zhang (Gus) (S’13–M’16) was born in Wuxi, China, in 1990. He received the BEng degree (first-class Hons.) in electronic and communication engineering from the City University of Hong Kong, Hong Kong, in 2012 and the PhD degree in electronic and electrical engineering from The University of Hong Kong, Hong Kong, in 2016.

          From 2016 to 2017, he was a Senior Research Assistant in the Department of Electrical and Electronic Engineering, The University of Hong Kong. He was a Postdoctoral Research Associate in the Research Laboratory of Electronics, Massachusetts Institute of Technology, Cambridge, MA, the USA from 2017 to 2018. He is now a lecturer in power electronics at the University of Manchester. His research interests include design and optimisation automation in power electronics, high-frequency ac–dc power conversions and designs and optimizations for wireless power transfer applications. 


Friday, 24 June 2022 (9:00 AM ET): "Electrical Design of Denmark's Future Energy Islands" by Christian Frank Flytkjær, Elnetanalyse, Denmark

Register


                     Abstract: The Danish power system is undergoing significant changes these years and so are the tools needed to predict the system’s dynamic behavior. Methods ranging in complexity from single bus-bar single frequency to detailed EMT and use of real-time HIL are discussed based on already identified and future needs. The presentation is centered around a series of examples ranging from grid integration and operation of wind power plant and interconnectors hybrids, design and integration of Denmark’s future energy islands (integration of power-electronic-based systems in power systems), dimensioning of fast reserves and key findings from a number of critical events that occurred in the Danish system. Strategies for ensuring model performance and maintenance are discussed as well.

CFJ     Biography: Christian is currently Senior Manager of Energinet’s Grid Analysis department a department responsible for Energinet’s stability and power quality assessments. Before he’s current role Christian was working as Chief Engineer also with Energinet. Christen obtained both he’s bachelor, master and PhD at Aalborg University in Denmark.
