[WiE Webinar] Distributed Secure Cooperative Control, Optimization, and Learning
Thursday 14 November 2024 at 8:00 PM CST, 1:00 PM CET, 7:00 AM EST By Wangli He (East China University of Science and Technology, Shanghai, China) Joint Webinar with IEEE Women in IES Register now using the link below: https://attendee.gotowebinar.com/register/4935455251698636119 Abstract: Cooperative collective behaviors in networks of autonomous agents have attracted considerable attention due to their wide-ranging applications across disciplines such as biology, physics, and engineering. The rapid development of large-scale networks and big data has led to the widespread application of distributed control, optimization and learning that rely on local information exchange. However, network-enabled information sharing and open setting of the network medium give rise to several security and privacy issues for practical MASs, thereby rendering resilient and privacy-preserving distributed cooperative control and optimization strategies and of both theoretical and practical significance. Existing schemes that rely on global information like network topology limit scalability in dynamic, large-scale systems. Furthermore, advances in information technology make multi-agent reinforcement learning a promising approach for complex tasks in high-dimensional, dynamic environments. An urgent issue that requires in-depth exploration is how to employ multi-agent reinforcement learning to solve scheduling and decision-making problems in electricity-hydrogen coupled integrated energy systems. This talk introduces recent results ...
An Insulation System Solution for Oil-cooled 800 V+ PWM Supply Electrical Machines
Wednesday 27 November 2024 at 3:00 PM CET, 9:00 AM EST By Shafigh Nategh (Sedrive, Sweden) & James Bonnett (Victrex, United Kingdom) Register now using the link below: https://attendee.gotowebinar.com/register/4349598072875749728 Abstract: With the growing demand for Battery-driven Electric Vehicles (BEV) to reduce the CO2 footprint and GHG emissions from the transportation sector, high-voltage batteries and wide bandgap converters (silicon carbide/gallium nitride) are critical research areas to enable more efficient BEVs with reduced charging time. The automotive motors are squeezed into small sizes for increasing torque and power supported by advanced cooling solutions. The direct cooling system is adopted more and more in the Electric Drive Unit of the propulsion system where the transmission fluid is shared with the coolant of the electrical machine. High-voltage supply systems, wide bandgap converters, and direct oil cooling impose high stresses on the insulation system. The durability of the high-voltage oil-compatible insulation system is required to ensure the lifetime and safe operation of the propulsion system. In this webinar, an insulation system is proposed and verified using an innovative test setup representing an 800 V+ PWM supply electrical machine. Presenters’ bio: Dr.-Ing. Shafigh Nategh (Senior Member, IEEE) was born in 1984. He received the ...
