Tutorial 1 - Smart transformer: its impact on distribution grid

The LV electric distribution grid is experiencing new challenges in terms of voltage and current limits violation, low inertia and low power quality due to the steadily increasing penetration of distributed generators and EV charging stations, leading to required reinforcement in electric grid. DC distribution and more controllability can reduce the needed reinforcement, and the Smart Transformer enables both. This tutorial introduces the Smart Transformer concept, considering architectures and power converter topologies aiming at high efficiency and reliability. Control strategies for the LV-grid to increase the distribution grid hosting capacity of the renewables and charging stations as well as innovative faulty management functionalities to ensure the continuity services are introduced.

Tutorial 2 - Advanced control strategies dedicated to power electronics systems

Design of passive storage elements in power electronics systems are closely bound to dynamical performances of the systems. Improvement of these dynamical performances can be realized thanks to advanced control strategies applied to power electronics systems. Another way to decrease costs of power electronic systems, is to develop sensoreless control using a reduce numbers of sensors. Ended it is possible to remove mechanical or electrical sensors to cheaper systems or for reliability purposes.

In this tutorial, we will follow the following outline:

  • Motivation: we will show throw practical examples the effect of control laws on the design of passive elements.
  • Controller design using Energetic approaches: Flatness based control and Passivity based control applied to power electronics and drive
  • Observer design in power engineering: from extended Kalman Filter to non linear observers applied to power electronics and drive.

Tutorial 3 - Design, modelling and control of linear induction motors

The main subject of the tutorial are linear induction motors (LIMs). Starting from a brief structural description of such motors, their main applications will be exposed in the tutorial with specific reference to MAGLEV (Magnetically Levitation) vehicles, urban people movers, X-Y planar motion industrial platforms, launchers, actuators for industry and automotive. As a first step, the main differences between rotating and linear induction motors will be highlighted, focusing on the aspects of static and dynamic end effects as well as transversal edge effects. The typical structure of LIMs will be treated, with specific reference to secondary sheet and primary winding configurations. Single-sided LIMs (S-LIMs) and Double-sided ones (D-LIMs) will be described, focusing on normal force effects. Design criteria of LIMs will be specifically exposed, emphasizing the main differences with the classic rotating induction motor design, caused by the presence of large air-gaps, high leakage inductances as well as the end effects. The static and dynamic models of LIMs will be introduced, including the so called end-effects. Suitable parameter estimation methods will be then described. Afterwards, control techniques specifically devised for LIMs, like field oriented control, input-output feedback linearization control and active disturbance rejection control will be introduced. Finally, sensorless techniques specifically developed for LIMs will be shown.

  • Intro on linear motors (LIMs)
  • Main applications of LIMs
