North American SynchroPhasor Initiative (NASPI) Technical Reports

You are here

These technical reports were developed by the North American SynchroPhasor Initiative, a collaboration between the North American electric industry (utilities, grid operators, vendors and consultants), the North American Electric Reliability Corporation, academics, and the U.S. Department of Energy, to advance and accelerate the development and use of synchrophasor technology for grid reliability and efficiency. The material was produced for a series of NASPI technical workshops intended to educate and document the stakeholder community on the state of the art for key synchrophasor technology issues.

For the renewables integration workshop, NASPI partnered with the National Renewable Energy Laboratory to explore the use of synchrophasor technology to enhance the integration of renewable generation. The workshop looked at how renewable generation can be increased, while protecting grid reliability, using synchrophasor technology. Synchrophasor data offers unprecedented insight into the interaction between generators and the bulk power system, enabling sophisticated engineering analysis that can improve grid design and protection. The report includes the workshop summary, agenda, and all presentations made by workshop participants.

The phasor tools visualization workshop compared the visual presentations offered by several commercially available phasor data visualization software providers. The goal of the workshop was to look at how the visualization tools display specific grid events. The report includes the final report for the workshop and the workshop agenda, as well as links to archived video clips of demonstrations shown during the February 2012 workshop.

The model validation workshop discussed the use of phasor measurement units (PMUs), which collect high-speed, time-synchronized data about grid condition. Data collected about a power plant’s behavior during a grid disturbance can be used to improve the model of that generator. The workshop featured technical experts explaining the value of phasor measurement units (PMU) data-based model valuation and presenting several examples of the model validation process and results for a variety of power plants. The workshop closed with discussion of the distinction between generator models and power system models. The report includes a summary of the model validation workshop, the workshop agenda, and all of the presentations made at the workshop.
