The increasing adoption of Smart Grids brings about significant benefits such as enhanced efficiency and sustainability, but entails also severe threats to consumer privacy due to the possibility of establishing detailed user profiles. Existing efforts mostly focus on privacy issues in Smart Metering. However, the Smart Grid contains other important use cases whose privacy challenges have not received much attention to date. In this paper we aim to raise awareness for privacy issues in e-mobility, which will be a cornerstone application of the future Smart Grid. In particular, we study in detail the properties of privacy-relevant e-mobility use cases, the actors involved in those scenarios, and the data they exchange as part of their interaction. We investigate to which extent existing solutions can be applied to address emerging privacy challenges in e-mobility, and propose privacy-aware design patterns.

This paper analyzes different Web service technologies that can be used for data exchange in Smart Grids. The focus is put on smart metering in electricity networks and the required data exchange for different application scenarios. It contributes a detailed comparison of available interface technologies, in particular Web services. The evaluation is performed based on a qualitative comparison using a criteria catalogue and literature research and a quantitative comparison based on an empirical field test using a test bed. The results show that binary protocols require less computational resources but lack several qualitative advantages. Furthermore it can be seen that recent optimizations for XML data exchange reduce the performance gap.

Abstract. The control flow graph is the basis for many code optimisation and analysis techniques. We introduce a new framework for the construction of powerful CFG-based representations of arbitrary Ada programs. The generated data holds extensive information about the original Ada source, such as visibility, package structure and type definitions and provides means for complete interprocedural analysis. We use ASIS-for-GNAT as an interface to the Ada environment and extract the needed information in a single traversal of the provided syntax trees. In addition, further refinement of the resulting data structures is done.

The current rise of electric mobility as a means of reducing CO 2 emissions in the traffic sector comes with the challenge for distribution power networks to host not only additional distributed generators but also additional loads -namely the electric vehicles. This work makes an effort to tackle the peak consumption challenge that, if not solved in time, would require additional investments for grid reinforcement. Coordinated charging of electric vehicles requires communication in the triangle of user, car and power grid. General options for vehicle to grid communication and their applicability are discussed from the viewpoint of a multi-utility system operator. This will be the foundation for an implementation of second-generation home charging stations in the smart grids model region of Salzburg.Generelle Optionen fü r eine Vehicle-to-Grid-Kommunikation.Der aktuell zu verzeichnende Aufstieg der Elektromobilitä t als ein Ansatz der CO 2 -Reduktion im Verkehrssektor wird begleitet von der Herausforderung, dass die elektrischen Verteilnetze nun nicht nur zusä tzliche verteilte Erzeuger, sondern auch zusä tzliche Lasten -namentlich die Elektromobile -aufnehmen mü ssen. Diese Arbeit widmet sich der Spitzenlastproblematik, welche im Falle eines ungesteuerten Ladens zu kostenintensiven Netzverstä rkungen fü hren wü rde. Das koordinierte Laden von Elektrofahrzeugen erfordert eine Kommunikation im Dreieck aus Benutzer, Fahrzeug und Stromnetz. Grundsä tzliche Optionen fü r eine Vehicle-to-GridKommunikation und deren praktische Anwendbarkeit werden hier aus dem Blickwinkel eines spartenintegrierten Netzbetreibers diskutiert. Diese Diskussion wird die Grundlage fü r eine zweite Generation von Home-Ladestationen in der Smart Grids-Modellregion Salzburg sein.
