The Eastern Interconnection is arguably the largest power system in the world, and its size and complexity have historically made it difficult to study in high levels of detail. In this study, NREL developed the most detailed model of this system ever made and then simulated operation of the system under normal conditions with very high combinations of wind and solar PV generation. Under the study assumptions, high penetrations of wind and PV generation--up to 30%--can be balanced on the transmission system at a 5-minute level with various configurations for transmission and generation. Results also indicate that high penetrations of variable generation (VG), primarily wind and PV, require traditional generating resources to be used less frequently and operate across a broader output range. The study gives grid operators and regulators insight on how the grid could operate with high renewable penetrations and the ability to plan for such clean energy futures.
