The Eastern Interconnection Planning Collaborative (EIPC) has established three major power flow cases for the 2030 Eastern Interconnection (EI) grid based on various levels of energy and environmental policies, technology advances, and load growth. This paper documents the procedures of developing 2030 EI dynamic models using parameters from the Multiregional Modeling Working Group (MMWG) model and using the generic models. The constructed model is validated indirectly using the synchronized phasor measurement by displacing wind machines with conventional generators.
