The broad electrification of the world economy, the continued deployment of renewables and the expansive means to reduce carbon emissions requires a reliable and resilient electric grid. Ensuring power system security and stability requires accurate, timely and verified synchronized measurements of time varying and noisy current and voltage signals, collected across vast electrical grids, numerous different electrical components and in the presence of volatile renewable energy sources. Synchronized measurements and their analysis provides insights for operational control and may enhance decisions in generation and grid investments. The infrastructure that enables, transmits, secures and stores synchronized measurements (incl. the cloud) becomes crucially important, too. The International Conference on Smart Grid Synchronized Measurements and Analytics 2026 (SGSMA 2026) is the leading forum for disseminating the latest research and innovations on this multi-faceted topic.
