Theoretical Aspects of Model Validation from Frequency Perspective

Abstract

In this chapter, the theoretical aspects of a framework for power system model validation from frequency viewpoint, including formulations and methods, are presented and described. This framework is applicable to large power systems and uses a quantitative method for comparing the measured and the simulated responses. In order to reduce the unnecessary complexities and efforts, the proposed framework is based on two main approaches and for each, uses the maximum capability of turbine-governor models. Since the framework considers the manual actions of the system operators and other emergency actions after an incident, the time frame of the validation can be chosen arbitrarily based on the availability of data. It should be mentioned that this framework also uses a method to increase the accuracy of the static data before an incident. The frequency and voltage dependency of loads are also observed in the framework even if accurate data is not available.
