Project description

The Distribution System Operators (DSOs) assure the reliable and efficient electricity supply to geographically distributed customers. The medium-voltage and low-voltage (LV) grids are in most cases still designed and operated based on historical assumptions for consumption and generation profiles. Furthermore, fault-localization in this part of the grid is to a large extent based on customers calls and subsequent inspection of grid comonents in the field. On the other hand, there is an increasing number of digital grid-related data sources, including Smart Meters at customer sites and inverters that connect storage or distributed generation, but the information from such data sources is not yet used for grid operation. The Net2DG project will develop a proof-of-concept solution based on off-the-shelf computing hardware that uses existing communication technologies to leverage measurement functionality from Smart Meters and DER inverters in the Low-Voltage grid. The Net2DG solution correlates this data with information from existing DSO subsystems, in order to enable and develop novel LV grid observability applications for voltage quality, grid operation efficiency, and LV grid outage diagnosis. The achieved observability is subsequently used by specifically developed novel control coordination approaches, which utilize the existing Smart Meter and inverter actuation capabilities in conjunction with selected existing DSO actuation for voltage quality enhancement and loss minimization in the LV grid. The use of off-the shelf components, the system level resilience and security solution,  and the offered customizability of the Net2DG approach specifically address the needs of small and medium-sized DSOs. Therefore, the Net2DG solution will make small and medium-sized DSOs early adopters of digital technologies for LV outage diagnosis, grid operation efficiency and voltage quality.
