Project Details
The Eastern Interconnection (EI) MMWG model uses constant current and constant impedance for P and Q load (PI-QZ) models as a rough approximation of load behavior. The power industry has begun to recognize the importance of more accurate load modeling. Though significant progress has been made in the local load modeling for studies like voltage stability and fault induced delayed voltage recovery (FIDVR), accurate load models are extremely hard to obtain due to their sheer number (38k in EI MMWG model), wide variety end-use load, and constantly changing nature. In addition, to what extent the very detailed load models are required in a large interconnection model is unclear. This study aims to incorporate and evaluate the role of composite load models in EI studies.
