Welcome toThe 22nd IERE General Meeting and 6th IERE Webinar
Toward Enhanced Resilience for Electric Power Systems
Power system instability caused by climate change, natural disasters, and human factors such as cyberattacks is a serious threat not only to our living environment, but also to the survival of life in the event of alarge-scale power outage. This webinar will introduce the latest technologies and countermeasures that are
being researched and developed to improve power system resilience.

"Enhancing Grid Resilience"
The issue of resilience to climate-related, physical and cyber events has
become one of the most critical issues facing the entire electric powerindustry. This is becoming even more critical as we electrify more and moreof society’s critical energy systems (e.g. transportation and heat). There aremany research needs associated with improving the electric system
resilience and making these investments in the most effective manner. Thistalk will highlight critical research needs facing the industry right now, suchas the value of resilience, the role of customers and communities, andplanning and operations tools. Hopefully, this can lead to a discussion
around industry coordination to accelerate development of tools andsystems to support the grid resilience requirements in the future.
Biography
He provides technical and strategic input and guidance across theorganization and for the electric utility industry around the world, working
from the EPRI Europe office in Dublin, Ireland.
He has authored more than 70 technical papers and articles on topics
ranging from power quality to insulation coordination of extra highvoltage(EHV) systems. He has been a leader in the development of smart grids forthe last 20 years. He is an IEEE Fellow and in 2014 received the Charles
Proteus Steinmetz Award for his expertise and dedication to powerengineering standards development.

Power Automation Department, CEPRI"The wide-frequency measurement technology for Inverter-based
power system—Improvement of awareness capability of resilient grid""The wide-frequency measurement technology for inverter-based powersystem—improvement of awareness capability of resilient grid" has threemain parts. Firstly, it briefly introduces the research on the concept and thefeatures of resilient power grids in China. Secondly, it presents thewidefrequency technology which can realize the measurement offundamentals, inter-harmonic and harmonic measurement in range
DC-2500Hz, and gives description of the method of wide-frequency
measurement, the system structure of measurement in substation and thefunctions of widefrequency measurement devices. Thirdly, the application ofwide-frequency technology is described, using the example of oscillation
events. It can replace the PMU (Phasor Measurement Unit) and improve theawareness capability of future resilient grids.
Biography
Mr. Fan Chen (Member, IEEE) received his B.E. and M.E. degrees fromSouthwest Jiao Tong University of China in 2004 and 2007, respectively.
From 2007 to 2012, he worked in State Grid Electric Power ResearchInstitute(SGEPRI). In 2012, he joined China Electric Power Research Institute(CEPRI) and currently serves as an excellent expert of CEPRI on smart
substation. His research interests include the implementation of IEC61850,
smart substation, and power system protection, control, automation andcommunication. From 2016, his main research area is wide-frequency
measurement technology and its application for inverter-based powersystem. He has published more than 40 papers indexed by EI Compendex
and had more than 30 invention patents.

Product Development Manager for Power Transformers, Prolec GE"Flexible Power Transformers to Improve Resiliency of Transmission Networks"
Due to Power Transformers are custom-designed components in the transmission network isdifficult to replaces in emergency situations such as: extreme weather events, unpredictability ofnatural hazards and deliberate attacks. If a spare is not available, a new power transformer must
manufactured with a process that can span months.
Prolec GE and GE Research developed a solution called Flexible Power Transformer specifically forutilities where different voltages and impedances may be required when considering the purchaseof spares. Instead of being solely dependent on a large pool of highly customized spare units,
flexible transformers with multiple low voltage ratings and adjustable impedance capabilitiescould be a simpler and more cost-effective solution, not only for emergencies, but as permanent
replacements.
Biography
Received his Bachelor degree in Electrical Engineering from Instituto Tecnologico de Morelia in1999. Then received his Master of Science in Electrical Power Systems from Universidad
Autonoma de Nuevo Leon in 2001. His employment experience included the Energy Control
Center, Mexico, and GE Global Research Center, US. Since 2003 works in Prolec GE held various
technology leadership positions, recently he is Manager of the Product Development team. His
current research interests include reliability and design for power transformers.

"Climate change adaption, new challenges for Substations Equipment Applications"
All over the wo
rld electric utilities are experiencing more frequent and extreme weather events due
to global climate change. 2021 was one of the worst years in records for storms and severe
events ranging from windstorms, heat dome, extensive wildfires, atmospheric rivers, and flooding.
The current planning and asset management practices using historical weather data/models topredict future extreme service conditions are not longer robust. These extreme weather-related
events and associated impacted load and generation profiles impose new challenges to powersystem planners and asset managers. In this presentation we will share our experience facingthese new challenges. There is a need for developing new supporting tools and application
standards to optimize capital investments and operation costs under this new climate paradigm.
Some of the topics associated with climate change adaptation for equipment applications
included in this presentation are:- Operation and Planning- Existing and new equipment- Stronger and new interdependencies- Suggested actions to mitigate impacts of climate adaptation
Biography
With over twenty years of experience in the energy sector, Dr. Jorge Hollman is a Principal
Engineer and the Senior Manager of the Substations Engineering Studies and the High Current
Lab departments at Powertech Labs. He is a recognized power systems expert and has
experience in modelling, transients simulation, point on wave switching, equipment specification,planning and operations. At Powertech, Dr. Hollman's teams are specialized in testing, consulting,and investigation services to support electrical utilities, equipment manufacturers, government,
and research organizations.
He is recipient of the José A. Estenssoro Award, the Kenneth George Wansacker Memorial Prize,
