Operational Analysis of the Eastern Interconnection at Very High Renewable Penetrations
- National Renewable Energy Lab. (NREL), Golden, CO (United States)
The primary objective of the study reported here is to build on work by Mai et al. (2012) and Brinkman (2015) by performing detailed modeling of the U.S. Eastern Interconnection operations with approximately 70% of all energy coming from wind and solar generation. The study assesses the ability to balance supply and demand for electricity using a unit commitment and economic dispatch model with a five-minute time resolution. In addition, the study explores the implications of different amounts of physical and institutional flexibility for balancing. We also present an analysis of system “stress” by quantifying various metrics, such as the amount of spare online capacity, penetration levels of non-synchronous generators, day-ahead compared to real-time curtailment, and start-ups of peaking generation.
