New trends in electric mobility – and a better use of renewables

Marco Venturini, CEO of Phase Motion Control S.p.A.

The coming of age of high performance batteries is revolutionising electric mobility at an accelerating pace. The current and coming generation of batteries offers both high energy density and the option of ultra fast charging, thus removing the two main obstacles to a  generalized replacement of IC engines in private transportation. Increasing investment across the industry is rapidly clearing away other minor, but multiple, problems, such as efficient and reliable cabling, protection, component packaging and so on. A revolution is on the way. On the supply side, the availability of a growing “battery on wheels” connected to the network, at least most of the time, can and will serendipitously solve the issue of network instability triggered by the increasing percentage of renewables generation in the grid. This means that a growing fraction of the EVs will run on zero energy or negawatt, i.e. renewable energy that would not have been otherwise harvested. A high challenge, but a very worthwhile work for the future of the world.

Marco Venturini (IEEE M ‘78, S.M. ‘83) was born in Genoa, Italy. He received the Doctorate, with honors, in Nuclear Engineering from the Politecnico di Milano, Italy, in 1977.

VSC Conversion Technology for HVDC & FACTS, State of the Art and Future Trend

Paolo Bordignon, Executive Vice President, R&D Coordination and Technology, Rongxin HUIKO Electric Technology Co.,Ltd

This speech is intended to describe the present State of the Art and future trend of Voltage Source Conversion (VSC)  Technology applied to Transmission and Distribution (T&D) Lines  in particular to High Voltage Direct Current (VSC-HVDC) and Flexible AC Transmission Systems (FACTS).

Taking into consideration the present state and future trend of  Power Semiconductor devices development,  Conversion Topology  and main Applications.

The applications, where  VSC-HVDC technology has been applied with major success,  until now are :   Interconnectors between countries and  transmission by submarine cables from Off Shore Wind Farms to On Shore Grid (main locations in North Europe) , Multi-terminals (MTDC) and  Back to Back (B2B) Ties (mainly in China). In near future we foresee important application of VSC technology  also in Long Distance Transmission (LDT) (China, India and Brazil or between continentals).
Some comparisons  in terms of power rating, performances, space  and losses has been evaluated between VSC-HVDC technology and the traditional one based on Current Source Thyristor conversion commonly known as  Line Commutated Conversion (LCC-HVDC ) , in China some Hybrid solutions VSC+LCC has been already applied in B2B and others will  be applied also in LTD in near future. We think Hybrid will become more and more important in the future to guarantee the best performances at lower cost and losses.
Regarding FACTS many solutions have proposed and deeply studied based on VSC Converter in Series (SSSC), in Shunt (Statcom) or both in Series+Shunt position (UPFC) to stabilize  high voltage AC line in transmission operation or against bad contingences. At present only Statcom has been extensively applied in real T&D projects  and now is also entering in heavy duty industrial sectors to improve Power Quality of MV industrial feeding lines.

Low Inertia Grids: towards a power electronics-based power system

Univ.-Prof. Antonello Monti, PhD , Director of the Institute for Automation of Complex Power Systems. E.ON Energy Research Center, RWTH Aachen University

The energy transformation is bringing more and more power electronics into the power system. As result, we are moving from a classical electromechanical system to a fully electronic driven system. This change is significantly affecting the dynamics of the power system but also opening completely new opportunities. The presentation will introduce recent studies in the field of dynamic integration of inverters in power grids showing that power electronics can be seen more as opportunities than as a problem. While a full concept of automation for future power system is still part of research, interesting options are emerging showing how the future power electronics-based power system could be actually more reliable than the classical power system.

Antonello Monti received his M.Sc degree (summa cum laude) and his PhD in Electrical Engineering from Politecnico di Milano, Italy in 1989 and 1994 respectively.  He started his career in Ansaldo Industria and then moved in 1995 to Politecnico di Milano as Assistant Professor.  In 2000 he joined the Department of Electrical Engineering of the University of South Carolina (USA) as Associate and then Full Professor.  Since 2008 he is the director of the Institute for Automation of Complex Power System within the E.ON Energy Research Center at RWTH Aachen University.

Integrated optimal design trends from non propulsive systems to hybrid power train of more electric aircraft

Xavier Roboam, Université de Toulouse, LAPLACE (CNRS/INPT/UPS), Toulouse

The environmental context of aeronautics (less CO2, les fuel burn, acceptability) is “drastically changing” and electrification of future aircrafts becomes a key driver. Whatever if non propulsive systems (<100kW, <540V) or hybrid (or full electric) power train (100kW-MW, xkVs) are considered, huge challenges have to be faced by designers in terms of technologies (passive devices, magnetic materials, wide gaps,…) and feasibility constraints (quality, stability, EMI, partial discharges, environment and mission profile,…). In this presentation, we propose to cross these key challenges with methodological vision related to the “integrated optimal design of more electric systems”. Indeed, the complexity of such processes involves innovative approaches such as the Multi-disciplinary Design Optimization.

Xavier Roboam, received the Ph.D. Degree of ‘Université de Toulouse’, France in 1991. He is full-time researcher (Directeur de Recherches CNRS) in the Laboratory of Plasma and Conversion of electrical Energy (LAPLACE) of Toulouse since 1992. He has been consultant expert for Airbus in the framework of “new architectures and integrated design of electrical networks” during 10 years until 2016. He has published more than 280 references with 12 edited books. His current research interests include integrated optimal design of multi-fields systems for transport and embedded networks (more electrical aircraft) or microgrids.
