DC grids

The increasing use of distributed energy generation and storage has led to local DC trial grids becoming an extension to traditional AC distribution networks. Like AC grids, DC grids must fulfil power quality (PQ) limits to guarantee reliable operation. However, knowledge about PQ in public DC systems and its impact on DC electricity metering is currently lacking, as is the related metrology and standardisation.

This three year project, which started in June 2021, aims to address these issues, in response to needs expressed by CLC TC8X WG1 (Physical characteristics of electrical energy) and IEC TC13 WG11 (Electricity metering equipment). This project’s goal is the traceable measurement and characterisation of PQ parameters to support standardisation in the further development and future use of DC grids and to ensure future customer confidence.

This work is supported in part by the European Metrology Programme for Innovation and Research (EMPIR), co-funded by the European Union’s Horizon 2020 research and innovation programme and the EMPIR participating states, under project 20NRM03 DC grids.

This project aligns with the strategic research agenda for EURAMET’s European Metrology Network on Smart Electricity Grids (EMN-SEG).
