Operational and Market Architecture for a Layered High-DER Power System

Virtual: https://events.vtools.ieee.org/m/519854

Distributed energy resource (DER/CER) technologies are expected to continue improving in performance and cost-effectiveness. As CER/DER penetration grows, the key system actors as well as policy makers and regulators must rethink core system roles and responsibilities supported by new functional capabilities. Millions of CER/DERs are becoming a key feature of Australia’s power systems and new approaches are required to enable the greatest individual, societal and system benefits from their participation including enhanced reliability and affordability. This presentation will describe a possible whole-system architecture that holistically addresses major CER/DER integration issues that Australia is currently grappling with. Key topics addressed will include Distribution System Operator (DSO) and Transmission-Distribution Coordination (TDC) models, the provision of grid services by CER/DER, distribution-level markets and integrated system <a href="http://planning.Speaker(s):" target="_blank" title="planning.Speaker(s):">planning.Speaker(s): Dr.Lorenzo Kristov, Virtual: https://events.vtools.ieee.org/m/519854

Arc-flash mitigation in ageing electrical assets: strategies, implementation, and case study Insights

9/340 Adelaide Street , Brisbane, Queensland, Australia, 4000

OverviewArc-flash hazards are among the most critical safety risks in electrical assets, particularly within ageing infrastructure designed prior to modern mitigation practices. This presentation outlines a completed project that modernised legacy protection systems in 22 kV and 3.3 kV switchboards supplying 1.85 MW and 2 MW pump motors via 3 MVA transformers, showcasing an end-to-end arc-flash mitigation strategy from study through to <a href="http://commissioning.The" target="_blank" title="commissioning.The">commissioning.The presentation will detail the key drivers behind the upgrade, including the replacement of obsolete GEC relays with advanced SEL protection systems, and the integration of high-speed arc-flash detection using both point and loop sensors, alongside current detection to confirm arc-flash events. The session also highlights the innovative protection philosophy that enabled dynamic logic in a brownfield environment, and discusses the design and implementation challenges encountered. Outcomes were validated through detailed power system and arc-flash studies, demonstrating significantly enhanced operator safety, improved compliance with Australian Standards, and extended asset life — all achieved through a cost-effective upgrade seamlessly integrated with existing SCADA <a href="http://systems.SpeakerIan ZareeiPrincipal Electrical Engineer, Persis EngineeringKoushik ChukkalaHV Commissioning and Electrical Design Engineer, Persis EngineeringProgram timeline- 3.30 pm AEST: Registrations- 4.00 pm AEST: Presentation commences- 4.45 pm AEST: Q&A- 5.00 pm AEST: Event concludesLearning outcomesIn this presentation, attendees will:- Discover how tailored protection design strategies were applied to meet specific site conditions and operational <a href="http://requirements.-" target="_blank" title="requirements.-">requirements.- Explore the implementation of advanced protection systems, including SEL relays and high-speed arc-flash detection <a href="http://technologies.-" target="_blank" title="technologies.-">technologies.- Gain insights into the design and commissioning challenges of upgrading legacy switchboards in a brownfield <a href="http://environment.-" target="_blank" title="environment.-">environment.- Learn a repeatable framework for arc-flash risk mitigation, applicable to both ageing infrastructure and new <a href="http://developments.Co-sponsored" target="_blank" title="developments.Co-sponsored">developments.Co-sponsored by: Engineers Australia9/340 Adelaide Street , Brisbane, Queensland, Australia, 4000

Scalar Reward is Not Enough: The Case for Multi-objective Reinforcement Learning

Virtual: https://events.vtools.ieee.org/m/514332

Abstract:The 2021 paper "Reward is Enough" by Silver, Singh, Precup and Sutton posits that the concept of reward maximisation is sufficient to underpin all intelligence, both natural and artificial. This talk will explain why scalar rewards are insufficient to account for some aspects of both biological and computational intelligence, and argue in favour of explicitly multi-objective models of reward maximisation. This talk will also provide a brief introduction to the field of multi-objective reinforcement learning, an alternative approach to reinforcement learning based on vector <a href="http://rewards.Speaker(s):" target="_blank" title="rewards.Speaker(s):">rewards.Speaker(s): , PeterVirtual: https://events.vtools.ieee.org/m/514332
