In the German Demonstrator, several different components and platforms have to communicate with each other. In the above figure, a simplified representation of the communication ways is given. From each of these constituents, data is exported or imported and, in most cases, both. These amounts of data have to be processed in order to utilize it for the internal functionalities within the German Demonstrator (State Estimation, OPF, … ). The amount of data and the individual processing times are crucial for the performance of the whole system. In the following, we will focus on the processes within the “Software Platform[1]” in Figure 1 above, which hosts most of the functionalities developed and used within EU-SysFlex.

 

Analysis:

The software platform makes use of two main data streams, namely forecast data and current grid data. The latter consists of grid topology, asset data and up-to-date measurements directly from the grid. Forecast data includes active and reactive power predictions of generators and consumers for 72 hours. In Figure 2 below, one can see data enters and leaves the software platform.

Processing of CIM data: Grid information is updated and exported from DSO regularly every 15 minutes. CIM CGMES data consists of four profiles – Equipment EQ, Topology TP, State Variables SV and Steady State Hypothesis SSH. A characterization of these files is…read more
