Validation of power system models

Since models form the basis for most power system studies, power system model validation is an essential procedure for maintaining system security and reliability. The procedure may be viewed as a “top-down” approach to model verification; comparisons with measured data indicate the quality of the overall model. Analysis of the differences demonstrates which subsystem component models need to be revalidated. Numerous examples are presented to illustrate the use and importance of system model validation.
