Title of the keynote: General Properties, Scaling Laws & Inherent Limitations of Energy Electronics


Power electronics converters are utilized in a multitude of applications for the electronic control and conversion of electric voltage and power and are reaching an increasingly higher performance, i.e. efficiency and power density at reduced costs. For each application, varieties of different converter topologies, semiconductor technologies, modulation- and control schemes, and ways of practical realization are feasible and the related details are intensively discussed at international conferences. By contrast, this talk describes the general background valid for all types of power converters, by means of elementary physical considerations and scaling laws, in order to establish a general understanding of fundamental limitations and potentials of advanced concepts such as, e.g., cellular multi-level converters.
The introductory part of the presentation explains the advantages of AC systems over DC systems in the early days of electric energy utilization and retraces the development of AC electric energy distribution in large steps. The second part focuses on the analysis of a single-phase AC/DC converter with regard to power flow pulsation and electromagnetic emissions, discusses principle advantages of SiC over Si power semiconductors, and defines the characteristic impedance of a converter, which is important for the evaluation of low-inductance packages and interconnections. The presentation continues with considerations on impedance matching, by means of parallel operation of multiple units, and a discussion of the advantages of phase-shifted operation, i.e. interleaving, with regard to switching losses and filtering effort. The third part illustrates the implications of main loss components on the resulting converter efficiency characteristic, discusses passive and active methods to filter the power pulsation with twice the mains frequency, presents a converter design by means of multi-objective optimization, and introduces the ‘Technology Node’ as a measure for characterizing the technological level of power electronics converters. Part four summarizes scaling laws and outlines possibilities for optimization of high-frequency transformers of DC/DC converters. A discussion of the ‘Hype-Cycle’ that is typically traversed after the introduction of a new technology, an outlook to important future technology domains of power electronics, represented in the form of a technology-S-curve, and an indication of future applications of power electronic converters, e.g. in the fields of green data centers, electric mobility, and More Electric Aircraft are concluding the talk.

Title of the lecture: Medium Frequency Transformer Design Optimization for Solid State Transformers


With increased interest in Solid State Transformers, several technical problems arise related to actual realization of these technologies. Irrespectively of adopted power electronic topologies, these structures are characterized as being modular and having inherently built-in galvanic isolation at medium or high frequency. Designing a high-power high-voltage medium frequency transformer is associated with multiple technical challenges related to electrical, magnetic, dielectric and thermal performance limits encountered in the system. Various technological choices must be carefully considered and selected before being included into a generic multi-objective optimization. Lecture will provide an overview and address challenges coming from the application area, characteristics of involved materials and available design choices, associated modelling of different elements impacting medium frequency transformer design, as well as optimization process as whole. Multiple illustrative design examples will be critically analysed in terms of their key performance indicators, and supported with practical examples realized in the laboratory.

Title of the lecture: A holistic testing approach for electric drive systems


The electric testing needs for drive systems have evolved far beyond the mere measurement of voltage and current. What could be considered traditional power measurement now represents only one out of several clearly distinct stages of electrical testing. Each one of these stages comes with its own challenges, which are exacerbated by the very developments that make precise measurement more indispensable than ever before: the race towards higher efficiencies, bringing ever increasing switching speeds in its wake. We will be introducing a five-stage model to describe test procedures for electric equipment and will be looking at specific examples to make visible the challenges occurring in each one of those phases to create awareness for potential pitfalls and mistakes on the way to a reliable assessment of power, losses, efficiencies and electromagnetic compliance of electric drive systems.

Title of the lecture: Electrification of Road Transportation Sector: Impact of Electric Vehicles on Distribution Networks


Electric vehicles (EVs) are widely recognised as one of the most promising technologies for reducing fossil fuel dependency and emissions of greenhouse gasses (GHG) in the road transportation sector, which is the only major sector where current GHG emissions are well above the 1990 levels. However, the further uptake and deployment of EVs require connection of large number of EV battery chargers, which will present a considerable challenge for the operation of existing distribution networks, as these loads might cause significant changes in power flows, with a further strong impact on the network voltage profiles, loading of network components, harmonic distortion levels and overall supply system performance. Currently, these changes are not fully understood.

Practically all car manufacturers are now offering different models of fully-electric and hybrid EVs, ranging from small and medium size passenger cars, through sport cars and sub-urban vehicles (SUVs), to vans and (mini)buses, which generally utilise different on-board EV battery chargers. The lecture will first introduce EV battery chargers as a new type of the load in modern distribution networks. Based on the extensive measurements of around 20 different types of on-board EV chargers, representing majority of EVs currently available in the EU market, the lecture will first discuss similarities and differences in their characteristics. Afterwards, it will be shown how complex and sophisticated power electronic and control circuits of different EV chargers can be classified into a small number of “generic types” and how the simplified “generic EV charger models” can be developed and used for different network studies, e.g. active/reactive power demand models, voltage-dependent load models, frequency-domain models, dynamic models for system reliability, security and stability assessment and high-frequency harmonic emission models.

Due to inherently stochastic nature of use of EVs, reflected in uncertainties in arrival and departure times, as well as travelled distances, charging locations and state of charge of batteries, the lecture will discuss how appropriate probabilistic models can be developed for the analysis of the aggregate impact of EV chargers, which should be considered together with the other types of loads connected in residential and commercial load sectors. Finally, implementation of flexible charging schemes for e.g. shifting EV loads to night hours and reducing differences between the minimum and maximum system demands, or for preventing curtailment of renewable energy and providing new balancing and ancillary services to network operators will be discussed for a selected number of EV charging scenarios, including use of EV batteries as a distributed energy storage in so called “vehicle-to-grid” applications.

Title of the lecture: Fuel Cell Technology for Automotive applications


The fuel cell is a potential candidate for energy storage and conversion in our future energy mix. Indeed, a fuel cell is able to directly convert the chemical energy stored in fuel (e.g. hydrogen) into electricity, without undergoing different intermediary conversion steps. Among the different fuel cell types, the proton exchange membrane (PEM) fuel cell has shown great potential in automotive applications, due to its low operating temperature, solid-state electrolyte, and compactness. Many experts consider the PEM fuel cells to be one of the potential embarked energy candidates for terrestrial transportation.
This lecture will mainly focus on the proton exchange membrane (PEM) fuel cell technology which has been used specially in automotive applications. The PEM fuel cell fundamentals, such as its physics, structure, power characteristics, efficiency, will be presented and discussed. The fuel cell system with its key ancillary components, such as air compressor, hydrogen tank, power converter, will also be introduced. Different powertrain configurations with fuel cells in automotive applications will be discussed and shown with real examples around the world. An emphasis on the fuel cell economic aspects and a short introduction to hydrogen economy will be given at last.

Title of the lecture: Multi-phase drive and generation systems for advanced industrial applications


Although multiphase (more than three phases) machines have been known for almost half a century, it is only in recent times that they are becoming more wide-spread in industrial applications. In addition to the obvious advantage of reducing the required power-per-phase and hence required semiconductor rating, multiphase systems offer a number of other advantages that make them suitable for specific but important niche applications. These all stem from the fact that, regardless of the number of stator phases, independent flux and torque control of an ac machine always requires only two independently controllable currents (two degrees of freedom). The remaining degrees of freedom can then be used for other purposes and this will be the subject of this lecture.

The lecture will commence with an introduction to the types of multiphase machines, principles of multiphase machine modelling, vector control, and multiphase voltage source inverter PWM schemes. ‘Classical’ (i.e. older) uses of additional degrees of freedom will be addressed next, including the multi-motor multiphase series-connected drive systems with reduced-switch-count inverter supply, use of the additional degrees of freedom for the purposes of achieving fault-tolerant operation, and torque enhancement or torque ripple smoothing by low order stator current harmonic injection. Next, more recent applications of the additional degrees of freedom will be considered. This encompasses capacitor voltage balancing in machines with multiple three-phase windings and multiple three-phase converters connected in series, realisation of fully integrated on-board fast (three-phase) and slow (single-phase) battery charging systems in electric vehicles, power sharing between three-phase windings in a multiphase machine with a multitude of said sub-windings, a braking method for induction motor drives with diode front-end rectifier, and stator winding temperature estimation. Basic concepts will be explained and illustrative examples will be provided throughout.

Title of the lecture:  About the role of power electronics in the grid until 2050


Fraunhofer ISE is working since many years on a model-based and sector-wide simulation of Germany’s overall energy supply system called REMod-D. The model takes all actual energy sources into account and calculates year after year with hourly values techno-economical meaningful paths to fully replace fossil energy sources by renewables. The goal hereby is to guarantee an almost CO2 neutral energy system by 2050. Photovoltaic and Wind being the major contributors of renewable energy with several hundreds of GW of installed power each, the electrical grid will have to handle enormous amounts of power and energy in the coming decades. Moreover, the grid will become the platform for sector-coupling since it will link the electricity sector with the other three major energy sectors that are mobility, heating and industry. In addition to this, another major challenge for our future energy supply will be the replacing of synchronous generators by power electronics. Indeed, inverters will not only interface generators and consumers with the grid as they are doing today but will have to control voltage, power and frequency at all grid levels. This will be done by advanced digital controllers as well as by reflex-functions within the converters but also by smart operational management on a superposed level. All in all, power electronics will take over crucial responsibilities in our future energy supply. After an introduction about our overall energy system today and in the future, the lecture will focus on the quantitative and qualitative role of power converters in future electrical grids.

Title of the lecture:  Sensitivity of Power Electronic Devices to Voltage Dips in Smart Distribution Systems


Successful transformation of existing electricity networks into the future “smart grids” essentially relies on the correct assessment and understanding of complex supply-demand interactions. In this context, Power Quality (PQ) remains to be crucial for the correct analysis of all supply-demand interactions, as it offers key indicators and metrics for describing and quantifying compatibility between the grid and customers’ equipment. From a “customer’s perspective”, the two important issues that will be discussed in depth in this lecture are a) increased sensitivity of modern power electronic equipment to various disturbances, when even a very brief voltage dip or short interruption can lead to their tripping or malfunction, and b) implementation of “smart grid” functionalities, e.g. flexible and intelligent controls, or increased automation and reconfiguration actions, which will improve system reliability, but might result in the more frequent or longer voltage dips and short interruptions.

The main aim of this lecture is to provide theoretical and experimental foundation for understanding voltage dips and analysing their impact and effects on the operation of modern electrical equipment in the context of “smart distribution systems”. In the first part of the lecture, existing PQ standards and various methodologies/procedures currently used for definition, characterisation, classification and presentation of voltage dips will be critically reviewed and discussed, as well as the most important parameters and factors that may influence sensitivity of equipment to voltage dips. Different ways for representing equipment sensitivity to voltage dips (e.g. voltage tolerance curves) will be discussed and illustrated using extensive results of testing of representative examples of different types of single-phase and three-phase equipment, which are reported as particularly sensitive to voltage dips and short interruptions.

Improved PQ performance is often assumed to be one the basic aspects of the “smart grids” and the second part of the lecture will provide a critical overview of some “smart grid” controls, e.g. increased network automation and reconfiguration operations, or implementation of automatic reclosing and sectionalising protection schemes, or high-speed switching to alternative and back-up supply points, which all typically result in multiple voltage dips (i.e. in “dip sequences”). Similarly, implementation of voltage regulation and reactive power control systems (i.e. “volt-var control”) may increase both the number and severity of voltage dips experienced by connected customers. The lecture will discuss how successful realisation of “smart grid” functionalities and services might impact overall system reliability and PQ performance levels and, particularly, customers’ perspective and perception of PQ in terms of dip sensitivity of their equipment. Finally, a novel analytical and experimental framework for assessing impact of dip sequences on equipment operation will be presented and discussed.

Title of the lecture: RES: the biggest match ever – Operational experience and innovative techniques to go cleaner, cheaper and safer


Important changes in the provision and consumption of electricity services are now underway, driven by a combination of factors affecting the transmission sector of power systems. A variety of emerging distributed technologies – including flexible demand, distributed generation, energy storage, and advanced power electronics and control devices – are creating new options for power plants, consumers at the points of connection and the needed investments in grid infrastructure. At the same time, information and communications technologies, as well as small-scale and large-scale battery systems are rapidly decreasing in cost and becoming ubiquitous, enabling more dynamic and efficient consumption of electricity, demand response, charging electric vehicles, improved visibility and predictability of network dots and enhanced control of power systems. With this framework in place, from an operational point of view, issues such as security of supply, resource adequacy, the need of flexibility, resiliency and grid stability, TSO-DSO cooperation, observability and data management are becoming increasing important as intermittent renewables generation claims a greater share in the energy mix. The other way round, from a planning perspective, topics like transparency, stakeholder engagement, sustainability and nature conservation, economic viability, grid aesthetics to gain public acceptance and accelerate permitting processes are posing huge concerns for TSOs who have to set the stage for a significant grid reinforcement. The special session panel “RES: the biggest match ever” touches objective and topics related to the operational experience and innovative techniques put in place by Terna and the ENTSO-E community in order to cope with this complete paradigm shift away from centralized fossil fuel systems to a more decentralized, decarbonized, democratized, diversified, digitalized and disruptive model. Just no name a few:

  • The energy transition and its challenges
  • Software and hardware solutions to efficiently integrate renewable energy
  • Climate change and the Italian resilience plan 2017
  • European trans-(regional) TSO initiatives
  • Resource adequacy Assessment and risk preparedness
  • Energy storage solutions
  • Underground cables
  • Legal & regulatory framework: Clean Energy Package, European network codes and Italy’s national energy strategy 2017

Title of the lecture: Power Circuits for Clean Switching and Low Losses


The lecture will teach the various effects of parasitic inductance (LS) in power electronics. As power density and current density is continuously rising, parasitic inductance and resistance become more and more the limiting factors. The problem is the product inductance times current (LS*I) rising, simultaneously, if designs do not improve. Not only overvoltage during switching is the problem but for bipolar power semiconductors like IGBTs and freewheeling diodes, parasitic inductance causes disadvantageous current waveforms. In systems which have snubber capacitors additional to the DC-link capacitor and parasitic inductance in between, oscillations between these capacitors occur. When considering power semiconductors in parallel the current sharing of controlled devices like IGBT, MOSFET and JFET can be affected by the presence of small parasitic inductance. Parasitic inductance in the control circuit (gate circuit) decouples driver and the gates of the devices leading to increased short circuit current, for example. To introduce these topics the tutorial will start with the basics of switching inductive loads and discussion of related waveforms. Investigations on the different effects will follow. The discussion of paralleling will be accom-panied by case studies. Geometries of conductors and system design for low parasitic inductance and good current sharing will be another main part and the conclusions will summarize the benefits of related system design – clean switching and low losses
