Development and Implementation of Composite Load Model in WECC

This paper provides an overview of a multi-year effort to develop and implement a composite load model for power system planning and operational studies by the utilities in the Western US Interconnection. The composite load model is a significant improvement over conventional static load model, as it better captures both damping of inter-area oscillation damping as well as events of Fault-Induced Delayed Voltage Recovery. The paper describes the structure of the composite load model, and the processes for creating and managing load model data sets for various climate zones and seasons in the Western Interconnection. The paper describes utility efforts to validate model using system disturbance recordings.
