The riesling project — Pilot project for innovative hardware and software solutions for smart grid requirements

The project RiesLing (Projekt im Ries - Leittechnik intelligent gemacht, translated "implementation of an intelligent grid control in the Ries area“) focuses on the development and the practical test of solutions which according to the project partners represent core components of a Smart Grid. The region of its implementation is the Nördlinger Ries, a region in the north-western part of Bavaria and in close vicinity to the federal state of Baden-Württemberg. This area combines a maximum load of around 50 MW with a maximum generation of around 120 MW, mostly from Photovoltaic modules and biogas fuelled engines. The RiesLing project has been initiated in mid 2011. Its technical implementation is set up as three separate packages. Two of these packages are dealing with innovative secondary equipment and communication solutions. These have been finished until end of 2012. Until mid 2013 additional functions for the grid supervision and control will be implemented, addressing power flow forecast and grid state estimation. The implementation phase will be followed by a test period, lasting until December 2013. This paper describes the aspects covered by the project and presents some of the results obtained until end of 2012.
