Recent advancements in power system oscillation research have revealed that phasor oscillations originate from the beating-wave phenomenon of voltage and current waveforms. Fourier analysis of these waveforms shows that certain spectral components, known as interharmonics, are the principal...

The synchrophasor data transfer standard (C37.118.2-2024) was revised recently. This webinar will describe the new features introduced in the updated version. It will provide a brief history of this standard, outline the revision needs identified through use, and explain how this revision addresses...

The NASPI DisTT will be having a call on March 20 at 9:00am PT / 12:00pm ET (.5 hr). If you are interested in attending this call and did not receive an invite, please reach out to Denise Ritzmann (denise.ritzmann@pnnl.gov).

Hydro power plant operation signature measurements for grid inertia estimation Speaker: Dr. Yilu Liu, University of Tennessee Knoxville and Oak Ridge National Lab The pump storage hydro motor shut off operation can act as a probing signal and will generate a well-defined signature each time this...

THE NORTH AMERICAN SYNCHROPHASOR INITIATIVE & IEEE SYNCHRO-WAVEFORM TASK FORCE, JOINT WEBINAR Synchro-Waveform Data Analytics Architecture and Big Data Platform for Grid Operations and Situational Awareness Presenters: Hamed Valizadeh and Michael Balestieri, Southern California Edison Emerging use...

Much of NASPI’s impact is due to the ongoing volunteer work that occurs within its task teams. These teams develop and promulgate best practices while serving as incubators for new ideas and approaches to solve common problems. During quarterly task team meetings, participants will have the...

Rich Bauer is the Principal Engineer for Event Analysis for the North American Electric Reliability Corporation (NERC). Joining NERC in January 2013, Rich promotes the understanding and learning from events and occurrences that are experienced on the Bulk Electric System. Rich performs forensic...

Recent BESS Oscillations: Root Cause Analysis and Wide-Area Impacts This webinar presents an opportunity to examine both root cause analysis and wide-area impacts of recent oscillation events. Monitoring and mitigation of oscillations like these are important aspects of reliable power system...

Timing is a critical element for synchronized measurement systems. Without a common clock capable of timestamping measurements within acceptable error, many synchrophasor applications cannot be utilized. While timing information from global navigation satellite systems (GNSS) has historically been...

Distribution grid monitoring: Challenges in developing PMU-rich feeders Increasing visibility into distribution grids requires upgrades to monitoring infrastructure. Advanced metering infrastructure (AMI) has only been minimally insightful in security and resilience cases, while the proliferation of...
