9:30-10:30
Speaker:
Maurizio Delfanti, RSE, Italy
Title:
The role of smart grids in the perspective of energy system evolution
Abstract:
Energy systems are undergoing a total revolution to achieve decarbonization goals. The transition towards net zero-carbon energy systems is particularly important at EU level: for this context, mid term plans (NECP, with target year at 2030) and long term strategies (LTS, with target year at 2050) have been set. Among the main innovations that will support the energy transition, a focus will be devoted to the widespread implementation of smart grid enabling technologies, that will play a central role. On the one hand, smart grids will manage a large amount of energy resources distributed throughout the territory, such as generation from non-programmable renewable sources, storage systems, bidirectional charging systems for electric vehicles and controllable loads. On the other hand, they will ensure adequate levels of security of the power system, also in the presence of new threats induced by climate changes.

Maurizio Delfanti graduated in Electrical Engineering at the University of Pavia, where he obtained his PhD in 1999. Since 2001 he has taught at Politecnico di Milano, since 2010 as associate professor and since 2016 as full professor at the Department of Energy. For Politecnico di Milano, he acted as Energy Manager, and was delegated by the Rector for energy management. He has carried out research/ consulting activities at national and European level on the regulation of power systems, in the areas of quality of service, operation of power systems in the presence of RES, smart grids technical and policy aspects, access to the dispatching market for new players.

Since 2019, he acts as CEO of RSE (Ricerca Sistema Energetico), a public research center which operates in the field of Italian System Research, also supporting national institutions on the matter of energy.

Bernard Wunsch, ABB, Switzerland
Title:
EMC Component Modelling and System-Level Simulations of Power Converters: AC Motor Drives
Abstract:
EMC simulations are an indispensable tool to analyze EMC noise propagation in power converters and to assess the best filtering options. In the first part of this talk it is shown how to set up EMC simulations of power converters and then in the second part their use is demonstrated on the example of an industrial AC motor drive. Broadband models of key power converter components are reviewed and combined into a circuit model of the complete power converter setup enabling detailed EMC analysis. The approach is demonstrated by analyzing the conducted noise emissions of a 75 kW power converter driving a 45 kW motor. Based on the simulations, the critical impedances, the dominant noise propagation, and the most efficient filter component and location within the system are identified. For the analyzed system, maxima of EMC noise are caused by resonances of the long motor cable and can be accurately predicted as functions of type, length, and layout of the motor cable. The common-mode noise at the LISN is shown to have a dominant contribution caused by magnetic coupling between the noisy motor side and the AC input side of the drive. All the predictions are validated by measurements and highlight the benefit of simulation-based EMC analysis and filter design.


Dr. Bernhard Wunsch received his PhD in condensed matter physics from the University of Hamburg in 2006. Later on, he worked as a postdoc on graphene, superconductivity and magnetism, before he joined ABB Corporate Research in 2011.

Marco Vinicio Bazzotti, ABB, Italy
Title:
RF-Conducted and Radiated Immunity for Low Voltage and High Voltage equipment
Abstract:
According to new editions of many product and environmental standards, the traditional radiated immunity test is now extended from 150 kHz to UHF frequency up to 6 GHz. New experiences of an accredited laboratory show the growing importance of these tests and their calibration, supporting both far field and proximity fields. As by standard request of high accuracy of both test equipment and equipment under test the operating laboratory is led to think towards a quantitative immunity concept approach.
Some real life examples for HV/LV testing (measuring relays, electronic circuit breakers etc.) are given.


Marco Vinicio Bazzotti graduated in particle Physics in 1991 in Milan University, then he switched to high voltages as a researcher for Italian ABB Corporate Research Center from 1991 to 1994.
Then he became expert in Electromagnetic Compatibility, from 1994 to day. Member of the IEC since 1996, he represented ABB in Italy at International Joint IEC Meetings.

Speaker:
Axel Junge, ESA/ESTEC, The Netherlands
Title:
Electromagnetic Compatibility in Space Power Systems
Abstract:
Spacecraft and satellite integrate sensitive equipment and payloads together with high-power equipment under stringent volume and mass constraints. The performance of radio-frequency (RF) equipment for instance depends also on the electromagnetic interference emitted and propagated by power systems operating at substantially lower frequencies. Suitable grounding and filtering concepts are fundamental to suppress conducted emissions, especially common mode, and subsequent radiation. To minimize required mass and volume of efficient filters, adequate converter and filter topologies need to be selected. Some fundamental trade-off criteria will be discussed together with related examples and test and analysis methods.


Axel Junge graduated with a physics diploma at Universität Bremen in 2001 and with an electrical engineering PhD degree (Dr.-Ing.) on EMC from Technische Universität Braunschweig in 2009. Since 2007, he is an EMC engineer at the European Space Agency (ESA) and works as a permanent staff in the European Space Research and Technology Centre (ESTEC).

Speaker:
Giordano Spadacini, Politecnico di Milano, Italy
Title:
Conducted Emissions in the Power Bus of Satellites
Abstract:
Among several requirements for the verification of Electromagnetic Compatibility (EMC) in the Space sector, those concerning conducted emissions (CE) are aimed at enforcing strict limits to radiofrequency currents flowing in dc power buses in a wide frequency range extending up to 100 MHz. This talk addresses a modeling methodology for the prediction of conducted emissions (CE) generated by dc/dc converters and propagating along the power buses of satellites. In particular, the dc/dc converter seen as a source of CE is represented by a behavioral model, whose parameters can be identified by two unit-level experimental procedures performed in controlled test setups. A simplified multiconductor transmission-line (MTL) model is developed to account for the propagation of CE in shielded bundles of twisted-wire pairs used as power cables. The whole power system is represented by the interconnection of the circuit models of dc/dc converters, cables, and the Power Conditioning and Distribution Unit (PCDU). By solving the obtained network, frequency spectra of CE can be predicted. Experimental results at unit and system level substantiate the accuracy of the proposed approach.


Giordano Spadacini received the M.Sc. (2001) and the Ph.D. (2005) in electrical engineering, summa cum laude, from Politecnico di Milano.

Speaker:
Paolo Crovetti, Politecnico di Torino, Italy
Title:
Interference of Spread-Spectrum modulated EMI and digital data lines
Abstract:
In this talk, the effects of electromagnetic interference (EMI) from power converters on analog and digital communications are addressed. More specifically, the spectral characteristics of plain and spread-spectrum (SS) modulated PWM switching waveforms is discussed and compared, both under the perspective EMC standards and with reference to their interference potential with wideband and narrowband communication channels. For this purpose, the possibility to describe the detrimental effects of EMI on data lines in terms of EMI-induced channel capacity loss is first introduced in order to rigorously address the problem in an information theoretical framework. Then, the proposed theory is adopted to discuss different application scenarios of practical interest, with a special emphasis on emerging power line communication (PLC) applications.

Title:
EMC challenges in Automotive systems
Abstract:
A successful Automotive project accomplishment is a mix of research, engineering, tests, material science, integration and industrialization. All these phases are subjected to an extremely tight and defined schedule, aiming to guarantee customer satisfaction while ensuring a perfect quality of the mass production. When all this is applied to complex EMI issues on Electric Vehicle Powertrains in which passenger safety is involved, the mission becomes extremely challenging. During the 45 minutes course a typical EMC Filter development for Automotive Application will be described from the early start of the project until its mass production. The goal is to show the audience how a project can pass through very different phases and different challenges; if the initial part is characterized by pure EMC debugging, simulations and research, more the SOP (start of production) get closer and more the challenges switch from pure Research to pure Development. All the different phases will be explained by showing examples coming from real projects.
