Implementation and Numerical Results

Abstract

In this chapter, the proposed validation framework in Chap. 3 is applied to a large and interconnected test grid by modelling all known parameters affecting the frequency behaviour, including the parameters related to the active load and the generating units and also implementing the improving measures of the framework. This chapter aims to illustrate the step-by-step implementation of the validation framework for a large power system and demonstrates the effectiveness of the framework, its methods and formulations. It is concluded that for the investigated test grid, first approach (using existing models) is not sufficient to validate the frequency behaviour due to non-modelling of all affecting parameters. So after identifying the prominent non-modelled affecting parameters, a new generic model is selected and the validation process is successfully performed using the second approach (the new generic model). It should be mentioned that DSATools and its associated modules of PSAT and TSAT are used as the basic simulation tools.
