Quantifying Transmission Fault Voltage Influence and its Potential Impact on Distributed Energy Resources
- National Renewable Energy Laboratory (NREL), Golden, CO (United States)
With increasing shares of distributed energy resources (DERs) on the electric grid, the power system is transitioning from having fewer large generators with relatively simple dynamics to many small generators with aggregate responses to system disturbances that are difficult to predict. In particular, voltage fluctuations might cause large losses of generation via DER operation/interconnection compliance. To understand orchestral DER dynamics, a first step is to determine the influence of a disturbance on the overall bulk power system. This work introduces metrics that allow for the classification and comparison of a variety of system faults with respect to their influences on voltage profiles. These metrics are applied to standardized fault simulations on the Western Interconnection Paths with a full-scale Positive Sequence Load Flow model. The results are presented with a highlight on Path 61, which has the potential for DER generation reduction exceeding the current credible contingency of a double Palo Verde loss.
