Register NOW as REGISTRATION WILL CLOSE APRIL 10th!!! IEEE SF & OEB PES will tour Ride Zum for PES Day for a unique opportunity to witness the groundbreaking integration of electric school buses with grid support technology. We will observe firsthand how their innovative fleet functions as a dual-purpose system—providing reliable student transportation while simultaneously serving as a distributed battery network that strengthens grid resilience during peak demand periods. The Vehicle-to-Grid (V2G) technology implemented by Ride Zum represents an engineering milestone, allowing buses to charge during low-tariff hours and discharge stored energy back to the grid when most needed, all without compromising school operations. This visit allows us to explore critical aspects including infrastructure readiness challenges, multi-stakeholder coordination between school districts and utility companies, and the practical hurdles overcome by early adopters in this space. The environmental benefits are substantial: reduced emissions improving community air quality, decreased fossil fuel dependence, and enhanced grid stability that accommodates more renewable energy sources. By showcasing this pioneering approach to transportation electrification, we gain valuable insights into practical applications that support both Earth Day's environmental protection goals and IEEE PES Day 2025's focus on innovative power engineering solutions for a sustainable future. AGENDA: 11:30am-1pm Lunch (TBD at a nearby location) 1:30-3:30pm Ride Zum Tour (more detailed agenda will be sent to registered and cleared attendees) Registration is due by April 10th. Ride Zum reserves the right of final approval of the list of registered attendees, their titles and organizations they represent (outside of IEEE) as part of the clearance check required for this facility. Emails will be sent to all registered attendees to confirm approval and with more detailed agenda and location. Speaker(s): Dr. Pallav Prakash, Oakland, California, United States

The IEEE SF & OEB Power & Energy Society (PES) Chapters invite you to join us on April 24, 2025 11:45 AM PDT, for a virtual Lunch-and-Learn PES Day event to hear Richard Hunt from Quanta Technology provide an Introduction to IEC 61850. Introduction to IEC 61850 IEC 61850 is a core standard for a smart grid, enabling data modeling of power system functions and sharing this data between applications using digital communications. IEC 61850 data can be used for dynamic equipment ratings to permit more load out of existing infrastructure, integrate renewable energy, detect falling conductors to reduce wildfire risks, even lower greenhouse gases by reducing the amount of copper wiring used in substations. This session will discuss the fundamentals of IEC 61850, including data model, communication methods, services, and configuration. Topics: - Why do we care about IEC 61850? - What does IEC 61850 do? - How does IEC 61850 work? At the end of the session, attendees should have a general understanding of IEC 61850. This session can be the starting point for further investigation into system and network architecture, testing, and implementing specific system functionality. Speaker(s): Rich Hunt, PE, Executive Advisor - Quanta Technology, Virtual: https://events.vtools.ieee.org/m/478617 |

Power system oscillation is a significant stability concern for utility companies, especially with the increased interconnection of inverter-based resources (IBRs). Traditionally, oscillations are investigated using phasor data. This presentation approaches the problem by examining the actual voltage and current waveforms underlying the phasors. It is found that oscillations are the appearance of beating waveforms in the phasor form. The beating waveforms, in turn, are caused by interharmonics (defined per IEC 61000-4-30). Notably, it can be proven that the presence of interharmonics is both a necessary and sufficient condition for phasor oscillations, and synchronous generator oscillations can be easily explained using interharmonics. Multiple field measurement results will be used to substantiate these findings. The interharmonic insights could lead to many innovative applications. Two of them will be shared here. The first one is to locate oscillation sources using measurement data. The second one is to determine generator participation factors based on small-signal power system dynamic models. Speaker(s): Wilsun Xu Agenda: 4:00pm - Event Starts 4:45pm - Q&A 5:00pm - Adjourn Times are in PST. Virtual: https://events.vtools.ieee.org/m/477906 |

Santa Clara Valley IEEE Power & Energy and Industry Applications Societies Co-hosted by SF PES, OEB PES, OEB IAS Join us April 30th for a presentation and discussion on: Design and Specification of Switchgear versus Switchboards including PV Source Connections to Switchboards Speaker: James Alvers, Siemens Business Development Manager Cost: IEEE Members $20 by 4/25: Non-Members $30 by 4/25 (After 4/25, if space available, registration will be $5 more and non-refundable as we have to commit to final meal and seating count) Date: April 30, 2025, 5:30 to 8:30 PM Place: Delta/Marriott Hotel Santa Clara-Silicon Valley, 2151 Laurelwood Road, Santa Clara CA 95054. Check hotel lobby to enter Parking Code GTSHR. 5:30 Check in, Meet and Greet 6:30 Dinner buffet 7:00 Talk 8:00 Q&A 8:30 End Registration required, early bird through April 25: Register now About the talk: Electrical power distribution relies on the connection of a series of different types of distribution equipment from the power source to the load. These are almost always low voltage switchboards and switchgear. Though the terms “Switchgear” and “Switchboard” are often used interchangeably and informally to describe a wide variety of electrical equipment, they have very different specifications and testing standards; even the NEC includes a different definition for each. Whether selecting electrical equipment for a simple commercial project, a data center, or a hospital, understanding the differences are important as they significantly affect reliability, safety, maintenance, size, cost, working space clearances, and more. This presentation will discuss the key differences between the two, to aid in application, design, and selection by consultants, contractors, and end-users. It will also cover the different types of circuit breakers used in switchboards and switchgear (e.g. molded case, insulated case, and power circuit breakers). Included will be photos of the internal construction and components to illustrate differences, as they are significant. This will help get beyond the single line diagrams and specifications for those who have not had opportunities to visit job sites or manufacturing plants to see the equipment. In addition, since designers are increasingly working on projects with photovoltaic (PV) inverter sources, questions arise on inverter connections and configurations for switchboards. This presentation will touch on NEC compliance, bus sizing, breaker position, customer needs (future and current), and manufacturer requirements. About the Speaker: James Alvers has been a Business Development Manager for Siemens Low Voltage Distribution Products since June of 2018. He assists electrical consultants in Northern California apply and configure cost effective, efficient, and compliant electrical distribution solutions for major infrastructure projects. Previously, James worked as a Data Center Electrical Engineer at Hewlett Packard/EYP Mission Critical Facilities. He has also worked for Schneider Electric as a Global Account Manager helping clients configure electrical infrastructure for data centers.
