Electrical energy generation and supply to users is on transition to distributed generation from traditional to renewable energy sources and development of Smart grids on “macro” “micro” and “nano” levels. Very fast research and development of smart DC grids is highly challenging and power electronics is the driving force of those new technologies. Power electronics in mechatronic and adaptronic systems, industrial robotics and wide range health care and iorobots with artificial intelligence are topics for further research. The explosive development of electric mobility, current and expected, will provide new challenges and opportunities; on one side, the progressive removal of fossil fuels, both in transport and heating/cooling, will increase the usage of electric energy; on the other side, a vast number of batteries, both on wheels and in fast charging stations, may contribute to resolve the intrinsic unpredictability of renewables. Ultrafast vehicle charging stations, in particular, are expected to be realized with significant storage capacity. Also, increasing the efficiency of power supplies reduces electrical energy consumption and may be counted as another way to reach that goal. Power electronics is also becoming crucial in electric power system, as it includes various types of energy storage technologies. In response to all these challenges, novel topologies, control structures and power components are being introduced to improve performance of power electronics systems. Especially, new wide bandgap materials (SiC & GaN) and the incoming power modules are a serious chance for a big step forward in a broad range of applications.

The following keynotes were given during EPE’19 ECCE Europe:
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.

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.

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.

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.
The following Technical Visits were organised in the frame of EPE’19 ECCE Europe:
Phase Motion Control specializes in all types of high performance PM motors and generators, from a few mm diameter to several meters. The visit will walk through all phases of high performance electronic motor manufacturing and testing and high energy magnet handling. A separate department is devoted to power electronics and high power charging systems for EVs, with a short walk through the manufacture of HPC charging stations with built in high energy Li-ion batteries.
The mission of the IIT Graphene Labs (G@IIT), https://graphene.iit.it/, is to develop two dimensional (2D) crystals, both for exploring fundamental phenomena and for conceiving their application in technological solutions. The G@IIT strategic plan is developing within the ten-year European Fet-flagship initiative Graphene, starting in 2013 and involving IIT researchers in different fields of activity, such as material production, energy generation and storage, health and biomedical applications, optoelectronics. Graphene Labs give strong emphasis to Technology transfer and dissemination by bridging contacts with different stakeholders
The group of Smart Materials, https://www.iit.it/research/lines/smart-materials is based at the central research facility of the IIT in Genova. The research of the group deals with the development of new composite materials combining various polymers and changing their properties by introducing nanofillers or organic molecules in the matrices. They work on both the control of the chemistry and of the structure of the materials we develop, in order to achieve precise properties adjusted to the needs of various application fields. Since polymers are the main building blocks of the materials that we fabricate, they have intensified our efforts in using natural polymers principally of plant origin or biodegradable polymers, in order to develop new advanced composite materials with accurately modulated properties but at the same time with minimal environmental impact.
The iCub laboratory space, https://iit.it/research/lines/icub, hosts several research lines providing support on all aspects related to the robot design, modification, fabrication, programming and use in the daily research activities. Our skilled personnel consists of about 80 people, 60% of which involved in research, the remainder dedicated to engineering and administration. The laboratory presently sports four iCubs in different configurations as well as the machinery required to assemble, maintain and run the robots, measurement and calibration devices, and the ICT infrastructure.
ASG Headquarters, with administrative offices and four production bays covering 15,000 sqm, is located in Genoa, near the port, in a strategic position in northwestern Italy.
In 2010, after winning the international contract to build 10 superconducting coils for the ITER project, ASG began work on a new production facility in La Spezia, also in Liguria and close to the port, which was completed in less than 18 months.
The visit will take place in the La Spezia plant.
The new ASG Superconductors production facility contains four bays, covers a total surface area of 25,000 sqm and is fitted with the new technology and logistics equipment needed to manufacture and handle large-scale components, like the superconducting coils for the ITER project now in production, which exceed 15 meters in length and weigh over one tons each.
The factory also has a clean area (controlled temperature and humidity areas complying with specific environment and air cleaning procedures) that covers 4,600 sqm and meets ISO Class 8 standards.
