An interim dynamic induction motor model for stability studies in the WSCC

Summary form only given. An "interim" composite load containing a static part and a dynamic part has been implemented in the WSCC. The static part of the load model is about 80% of the total load and comprises of existing static load data from the WSCC members. The dynamic part is a default induction motor model for approximately 20% of the total load. This composite model is used for all loads in the full-scale WSCC grid models that are the basis for system interconnection studies. The model is designed primarily to capture the effects of dynamic induction motor loads for highly stressed north to south flow conditions during summer peaks in the WSCC.
