Sandia Report Offers Reliable Way to Evaluate Unintentional Islanding Risk

A recently released Sandia National Laboratories report, “Suggested Guidelines for Assessment of DG Unintentional Islanding Risk,” outlines a procedure to help utility distribution engineers determine the risk of unintentional islanding in distributed energy generation installations. By providing a quick and reliable way to identify situations in which such risk is negligible, Sandia’s approach can help [...]

Energy Supply Transformation Needed

A lot that needs to be done to enable the transition towards larger shares of renewables in the power mix. The 5th International Conference on Integration of Renewable Energy and Distributed Energy Resources [4–6 December 2012, Berlin, Germany] brought together global participants from the energy sector to discuss the transformation of the power system, the challenges [...]

Sandia and the U.S. Army Collaborate on Operational Energy at Fort Devens

Daniel Borneo and Ben Schenkman (both in Sandia’s Energy Surety Engineering and Analysis Dept.) are working on microgrids with Ft. Devens’ Base Camp Integration Laboratory (BCIL). They have been involved in successfully testing an application that can also be used for the civilian power grid. This demonstration and deployment work is consistent with the energy [...]

Sandia to Co-Host International Workshop on Photovoltaics (PV) Penetration

Sandia National Laboratories, the Electric Power Research Institute (EPRI) and European Distributed Energies Research Laboratories (DERlab) have organized a workshop on utility operating experience with high solar PV penetration levels. The workshop, “Utility Experience with High Penetration PV,” is scheduled Monday, December 3, in Berlin. The workshop will take place just before the Fifth International [...]

North American Electric Reliability Corporation (NERC) Report Posted

The Integration of Variable Generation Task Force (IVGTF) Task 1–3 report, “Interconnection Requirements for Variable Generation” was posted to NERC’s website in mid-October. Many of NERC’s existing interconnection standards and procedures have been based on technical characteristics and physical capabilities of traditional power generation resources that employ synchronous generators. With the global trend toward renewable [...]
