A Decade of Dedication: NERC’s Contributions to Navigating Inverter-Based Resource Risks During the Energy Transition
Seven years ago we at the North American Electric Reliability Corporation (NERC) sprang into action to help industry understand inverter-based resource risks following the notorious Blue Cut Fire in California in 2016. Since then, I am … [Read more...]
DER Data, Modeling, and Studies: An Industry Conundrum (Part 2)
As mentioned in Part 1 of this blog, one cannot define the impact of distributed energy resources (DERs) without some form of assessment or study that can qualitatively or quantitatively provide a technical basis for that determination. Increasing … [Read more...]
DER Data, Modeling, and Studies: An Industry Conundrum (Part 1)
I am often asked, “what threshold should the industry use for defining when distributed energy resources (DERs) have an impact on the bulk power system (BPS)?” This usually has a trailing explanation about how defining a threshold for impact will … [Read more...]
Bulk Power System Impacts of Aggregate DER
The grid is changing, and we are starting to feel excited and frightened at the same time. If you aren’t, you should be. Because this stuff is frighteningly exciting. Many of us, including our friends, family, neighbors, and colleagues, may have … [Read more...]
Recent Bulk Power System Disturbances Involving Solar PV: NERC Efforts to Ensure Reliability
The electric grid as we know it is changing. The generating resource mix is shifting with the retirement of natural gas, coal and nuclear plants combined with the introduction of renewable energy resources such as wind and solar photovoltaic (PV) … [Read more...]
