Smart micro-grids – Properties, trends and local control of energy sources.
Abstract. After a general introduction of the main properties, benefits and challenges of the smart grid, the lecture focuses on low-voltage residential smart grids (smart micro-grids), which represent a new and huge potential market for ICT. In fact, the distributed energy resources acting in the micro-grids (renewable sources, storage batteries, etc.) interface with the distribution network by electronic power processors (EPP), whose synergistic operation may result in full exploitation of energy sources, increase of distribution efficiency and voltage stabilization across the micro-grid. This requires distributed cooperative control algorithms, which are implemented locally in each EPP and feature plug & play operation. The lecture analyzes some basic cooperative control principles which allow automatic integration of new energy resources, provide quasi-optimum operation of the micro-grid, and require only narrowband communication among neighbor units.

RF building blocks and techniques for low power wireless transceiver
Abstract. The reduction of power consumption in modern wireless transceivers can be achieved following two main strategies: the power recycling and the power re-configurability. In the first case, a long-lasting battery life is obtained with a penalty in performances while in the second case with an increment of the complexity. Both these approaches will be discussed: current re-use techniques applied to GPS and WSN receivers, while power scalability concept applied to some RF blocks of a cellular transceiver.

Power Line Communication Systems in the Smart Grid Context
Abstract. The seminar will focus on Power Line Communication (PLC) Systems: telecommunication systems that are among the most interesting in the Smart Grid context. PLC systems exploit the electrical wires to convey information data. This can translate into reduced installation time and cost for the telecommunication infrastructure that is necessary for the management of the grid through supervision and control mechanisms. The seminar will offer an overview of PLC applications. Then, we will discuss relevant aspects related to the channel characterization, channel modeling, and we will describe reliable transmission technologies and techniques. Finally, we will present some relevant PLC standards, both narrow band and broad band, and discuss their application in the Smart Grid.

Advanced devices for efficient power conversion for green applications
Abstract. Green applications have entered the news not only since the recent natural disasters. They have also changed our way of considering every modern commodity. Electronic power devices and circuits are the engines of this technical development which is steady, breathtaking, and still – progressing extremely dynamically. The tutorial will give an overview on electronic devices for power applications with a focus on the developments induced by recent progress in the wideband gap semiconductor world. This includes the discussion of trends such as higher conversion frequencies, more compact designs, and faster switching and related issues. The tutorial will be divided in three parts: in a first part it discusses material properties of group III-nitride semiconductors for power applications. In a second part advanced power devices and circuits are given for both group III-N as well as silicon technology including, e.g., FET, COOLMOS and IGBTs. The third part yields a mutual comparison and circuit examples are given for various green applications.

Future Trends in Zero-Power Systems
Abstract. Zero-Power systems may contribute to many applications in various sectors. Among them portable autonomous systems could open new endemic scenarios for wireless sensor networks, in situ monitoring for mobile/moving systems, body area networks, biomedical devices, portable power generation for mobile electronics. Special attention has been given to the market drivers for adopting energy harvesting devices in different market segments, factoring the progress of competing technologies and cost constraints. This presentation is aimed at giving an overview of this emerging field where energy aware electronic design is of strategic importance. However, since the processes of scavenging, transforming and storing energy are strictly inter-dependent, design optimization procedures should be treated using an integrated approach from a system perspective.
