Plenary Lecture:          Freedom and Evolution: Hierarchy in Nature, Society and Science.

Abstract: Evolution is the defining phenomenon of nature. This lecture outlines the role played by freedom and evolution in physics (thermodynamics): given freedom, movement exhibits the tendency to evolve into configurations that provide greater access. The lecture traces the modern evolution of flow systems that morph with freedom toward greater flow access, in accord with the constructal law. The progress is in two ways, incremental and with sudden step changes in flow configuration and performance. All this is predictable. The doctrine of evolutionary (constructal) design teaches how to predict evolution in general, and how to fast-forward technology evolution. The human today is a construct much larger and more complex than the human body examined in isolation. An individual today is a flow system that covers the globe. Each of us is becoming a better and thicker spherical shell of flows connected all over the globe. Our devices, from automobiles and air conditioners to schools, hospitals and Internet fill the global human shell, which thickens constantly during the human geological age. We are the human & machine species.

His areas of interests includes: design and control of grid-connected converters for photovoltaic, battery storage and wind power systems, HVDC/FACTS based on MMC, Smart Battery and lifetime based on artificial intelligence.

Plenary Lecture:          Smart Battery

Abstract: This disruptive Smart Battery concept will first revolutionize the hardware architecture of battery systems by adding cell-level switching capability, software reconfiguration and wireless data communication and secondly by using the mature Machine Learning (ML) technology, ground-braking functionality will be developed including life-time control and chemistry/aging independent performance for second life time reconfiguration. The critical challenge here is not adding "brains" to each cell for monitoring and state estimation (like IoT), but the cell switching capability, a device that will be able to optimize the charging/discharging current profiles flor lifetime extension, isolate a faulted cell and make the charger/load converters redundant. In other words, will transform the battery cells in building-blocks, that will significantly ease the design effort in applications raging from kW to GW. We have seen this kind of revolution in power electronics by the development of power modules which made the power converter to be virtually present in all energy applications today.

Plenary Lecture:          Optimised Electrical Machine Designs for E-Mobility Applications

Abstract: Transport electrification is seen as one of main solutions to reduce global CO2 emissions and increased demand of mechanical energy can be provided by electrical energy. The best energy conversion systems are undoubtedly the combination: electrical machines + power electronics + batteries. The increasing demand of full electric vehicles arises specific challenges in terms of design for manufacturing, low weight, material costs and material supply chain. There is a strong interest to reduce the volume and cost of active materials in propulsion motor technologies beyond their current state-of‐art, with a strong focus on industrial feasibility for mass production. Potential solutions include increased motor speeds and higher pole numbers and/or the adoption of rare earth free typologies such as reluctance (switched and synchronous) and induction machines. As there can be significantly different usage and performance requirements across e-mobility applications adopting a common standard of motor design is unlikely to yield the optimum in terms of overall system efficiency and electric vehicle range. These considerations will be discussed and compared.Cutting-edge sensitivity analysis and multi-objective optimisation techniques will be applied in the design of an electric motor for a PHEV traction application. Each candidate solution will be evaluated in terms of electromagnetic, thermal and mechanical behaviour across the full operating envelope. The optimisation will generate a pareto front which allows efficiency over a drive cycle to be traded off against motor cost. This approach utilises a high performance or cloud computing infrastructure to deliver a truly revolutionary design workflow.

 

DanielaFloriana D. Stoian is Professor of Engineering Thermodynamics and of Power Plants and is also affiliated with the Magnetometry Lab, Research Center for Complex Fluid Systems Engineering, Politehnica University Timisoara.

Plenary Lecture:          Magnetic and Transport Properties of Concentrated Magnetic Nanofluids for Use as Liquid Core

Abstract: Magnetic nanofluids (ferrofluids) have already proven their capabilities in various electrical and power engineering related applications, including for cooling and insulation of power transformers. Recent researches showed the potential of using magnetic nanofluids as a magnetic liquid core in miniature-sized transformers, by replacing partially or totally the solid ferrite core. Results of the investigations on the magnetic and several transport properties (rheological, magneto-rheological, thermal and electrical) of concentrated magnetic nanofluid samples, prepared for use as liquid core in a planar micro-transformer, are presented. Potential advantages with reference to the corresponding properties that a ferrite core should fulfil are outlined.
