Abstract
This chapter illustrates, by a practical case study, an application of the dynamic model reduction for a large power system model. This example concerns the creation of a reduced-order model from a full WECC model, to be used by BC Hydro for on-line dynamic security assessment (DSA). This model reduction was conducted using the software DYNRED. The focus of this case study is on the objective of the model reduction, the approach and procedure, the results, and the benchmarking work to ensure the suitability of the reduced models for the required applications. It is shown that, following the procedure used in the case study, a reduced model can be obtained for use with a wide range of system conditions with acceptable results and computation time saving.
