With the advancement of Ethernet, many of the old protocols have disappeared and made room for a handful of protocols that are being used more commonly across multiple industries. On the other hand, with the recent expansion of the Internet in every sector of our society, we are seeing a wave of new protocols. While some of these new protocols are used for IoT applications, several others are being developed to support new industries such as renewable energy and distributed Energy Resources. In this presentation, we go over a few conventional protocols and open the floor for discussion on discussing new protocols that have been developed in recent years. Biography Matt Eskandar graduated from the University of Alberta (Edmonton Canada) in 1991 with a B.Sc. in Electrical Engineering. Matt Eskandar started MR Control Systems International Inc. (www.mrcsi.com) in 1991 and has been the CEO of this company since then. Matt’s extensive experience in monitoring, control and automation projects worldwide has inspired him to develop a new generation of Monitoring and Control platform for SCADA, Data Analytics and Industrial IoT applications. This new platform allows users to build modern monitoring and control solutions that not only provide core SCADA functionalities, it also addresses many issues associated with Historians, Reporting, the convergence of SCADA, IoT and IT systems. As an experienced SCADA Engineer, Matt has been involved in execution of over 300 SCADA projects worldwide in multiple industries including Power Utilities, Renewable Energy, Water Resources and Oil and Gas. In 2012, Matt was instrumental in starting the Southern Alberta IEEE Control Systems and Instrumentation joint chapters. Matt has helped this chapter to grow its audience to over 1000 professionals. In 2017, Matt became one of the eight founders of the Alberta IoT Association. The Alberta IoT Association is one of the fastest-growing associations in Canada. Matt is an active member of APEGA, EGBC, and IEEE.

Abstract "When you can measure what you are speaking about, and express it in numbers, you know something about it." Lord Kelvin. Synchronised measurement technology, more specifically the Phasor Measurement Unit (PMU), has yielded tremendous insight into power system phenomena over the last decades. The PMU, however, is an instrument that is not itself well understood by many who make use of its measurements. The time synchronised phasor, or synchrophasor, is a double-edged sword; on the one hand it has made it possible to apply classical methods of power system analysis to “real” data from real systems. On the other hand, the synchrophasor dispenses with all the nuance of the voltage or current waveform that was present in the sampled values from which it is estimated. What if we just keep all of the time synchronised sampled value (TSSV) data, and use that for our studies? Building machines which can do this is more than feasible. This talk will discuss approaches and challenges that engineers pursuing this strategy face, in particular the not so small matter of the many terabytes of data such a system will create, with “needle in a haystack” levels of useful information. The talk will describe an effort on the island of Ireland to build a national system to record TSSV and also synchronise using PTP in preference to GNSS and its “space-based” vulnerabilities. Speaker’s Bio David Laverty (Senior Member, IEEE) received the Ph.D. degree from Queen’s University Belfast, Northern Ireland, in 2010. His thesis was on the use of synchrophasors for real-time control of generator sets via the Internet, investigating matters related to latency, packet loss and cyber security. He was appointed to a permanent post at the School of EEECS in Queen’s University Belfast in 2011, where he is presently a Reader (Full Professor, in North America). His work continues to address matters related to power system measurements, particularly time synchronisation, data systems, machine learning and cyber security. He is known as the founder of the open source project “OpenPMU”, which continues to develop open source hardware and software related to Phasor Measurement Units. His recent work is concerned with alternatives to “space-based” time signals, i.e. GNSS, in order to provide a resilient time transfer solution on which electrical utilities and other critical national infrastructure can depend.

Abstract If you look up "phasor measurement unit" on Wikipedia, you will learn a little about PMU that is right and a lot that is wrong. (To start with, phasors predate Steinmetz.) If you turn to the various papers and books that have been written on the topic, you will still not get the whole truth. Even the IEEE and IEC standards about PMUs have got significant parts wrong! If a PMU is built so as to fully comply with the standards, it will be an under-performing device that breaks the fundamental rules of measurement. The presenter, Dr. Harold Kirkham, is listed as a member of the working group that wrote the 2011 IEEE PMU standard. However, he was so upset by it that he is NOT listed as having voted for it! It has taken him a long time to figure out exactly what is right and what is wrong about the standard. This webinar will set the record straight and explain what is wrong with the current treatment of the subject. Speaker’s Bio Harold Kirkham (Fellow, IEEE) received the Ph.D. degree from Drexel University, Philadelphia, PA, USA. His thesis was on the control of the real and reactive power of HVDC terminals to stabilize the AC power system. After a few years at American Electric Power (AEP), he went to NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, CA, where he managed a DOE project that in many ways was a forerunner of the Smart Grid today. He worked at the Pacific Northwest National Laboratory (PNNL) 2009 – 2021, spending a significant fraction of this time studying PMUs. He is now the Principal Researcher of DRM Associates, Richland, WA, USA. Dr. Kirkham is a member of IEEE PES, IMS, DEIS, Communications, and Oceanic Engineering Societies. For several years he chaired the IEEE PES Instrumentation and Measurement Committee. He was a member of the working group that wrote the IEEE PMU standard C37-118.1-2011.
