IEEE made available the industry's first uniform test plan for evaluating the conformance of synchrophasors to IEEE C37.118.1, IEEE Standard for Synchrophasor Measurements for Power Systems. Introduction of the IEEE Synchrophasor Measurement Test Suite Specification is another key step toward a comprehensive conformity assessment program for synchrophasors, which provide real-time measurement of electric power grids to help ensure stable operations and avert blackouts. The U.S. National Institute of Standards and Technology (NIST) supported development of the IEEE Synchrophasor Measurement Test Suite Specification, toward the goal of encouraging market adoption of synchrophasor technologies supporting a highly resilient and reliable grid capable of accommodating higher penetration of renewable resources.
