Detailed Sensitivity Analysis

Abstract

In this chapter, the effects of different affecting parameters and improving measures on frequency validation are investigated by developing various scenarios based on the validated simulation. These scenarios are developed in three main groups which are the parameters of the loads (voltage and frequency dependency), the parameters of the turbine-governors (participation in primary frequency control, droop, dead band, practical powers, activity range, frequency ramp rate, and various turbine and governor time constants), and the improving measures of the framework (pre-incident frequency correction, secondary and tertiary emergency actions, static data correction, and the use of accurate governor parameters). Qualitative and quantitative comparisons of these simulations with the measured frequency profile and also the validated simulation show that considering all of these parameters and improving measures are vital for successful power system model validation from the power system frequency point of view.
