Digital Low-Voltage Distribution Platform for Dynamic System Operation based on the Clustering Power Systems Approach

The increasing share of decentralized power generation, which is now predominantly based on renewable energies, leads to higher demands on grid operations with regard to the stability of power supply systems. In particular, at the distribution grid level, where most decentralized generators are currently connected, must be realigned for this purpose. Technical solutions are needed with which the dynamic system service can be efficiently implemented. With the developed Clustering Power System Approach (CPSA) based on the Fractal Automation Architecture (FA
²
) for structuring electrical grids, a corresponding transformation of the distribution grids is possible in a structured and transparent way. Based on the FA
²
, an integrated automation platform has been developed for this purpose. This platform consists of a resource-integrated sensor system, a digital low-voltage (LV) busbar measurement system, and a Smart Grid Cluster Controller (SGCC) in combination with a multifunctional energy and power server. The developed platform is currently being tested under real conditions in a German distribution network. This paper presents the developed smart grid platform based on FA
²
with the technical system features. It is classified according to the technical system properties.
