The sun emits coronal mass ejections consisting of charged particles, and approximately 3% of these ejections reach the Earth with varying intensities. The interaction of the ejections with the Earth’s magnetic field is called a Geomagnetic Disturbance (GMD). GMD events pose potentially severe, widespread effects on the reliable operation of the bulk power system which may result in voltage collapse and blackout.
The North American Reliability Corporation (NERC), with FERC approval, has mandated two Standards relevant to protecting the electric grid from Geomagnetic Disturbance (GMD) events:
- Reliability Standard TLP-007-1 “Transmission System Planned Performance for Geomagnetic Disturbance (GMD) Events”
- Reliability Standard EOP-010-1 “Geomagnetic Disturbance Operations”
These standards require entities to assess the vulnerability of the bulk power system to GMD events, and to implement operating plans and processes to study GMD power grid impacts and mitigate potentially adverse effects.
This webcast will provide an overview of what a GMD event is and how it can impact the power grid (AC and HVDC systems). The webinar will identify the steps transmission organizations such as ISO’s, transmission companies, balancing areas, vertically integrated utilities and load serving entities need to take to adhere to FERC and NERC compliance obligations. Further, Teshmont will provide a GMD case study to illustrate how these entities can effectively comply with NERC Standards and build the resiliency of their power system to withstand GMD events.
- Review what a Geomagnetic Disturbance (GMD) event entails and its potential impacts
- Discuss FERC and NERC compliance obligations related to GMD events
- Assess requirements of NERC Reliability Standards
- Identify the steps on how to conduct GMD power system vulnerability assessments
- Evaluate tips for the development of operating processes for NERC and FERC compliance
- Review power support requirements to ensure compliance with the NERC Standards
- Review studies to analyze the effects of harmonics added during transformer half cycle saturation
- Identify possible equipment mitigation strategies
