Automated consolidation of dispersed DSO data resources into a consistent digital twin of the distribution grid
Abstract
The energy transition causes a growing number of distributed flexible energy resources in the low voltage grid. To utilize that flexibility, automation and control algorithms are needed, which typically are developed in theoretical research. We build a cyberphysical algorithm test bed to bridge the gap between theoretical research and practical application in cooperation with a local DSO in Walenstadt, Switzerland. To obtain suitable monitoring and data analysis capabilities from their existing data landscape, we propose tool-independent data harmonization measures in preparation for a digital twin of the grid. For data extraction from high-security network zones we developed a secure pipeline that implements a logical data diode ensuring one-way traffic only. Furthermore, we established a test community of voluntary prosumer households, whose flexible assets were made accessible through a common backend, giving us actuation capabilities. The presented publish-subscribe architecture is not only suitable to integrate various data sources into a central data collection, but also to manage access privileges of different stakeholders. This could support unbundling of an organization's data flows and the implementation of data space concepts.
