Background
Frequency Responses > Frequency Events Analysis > Texas Interconnection
Fundamental changes are taking place throughout North America in the way that electricity is produced and consumed. These emerging technologies are are resulting in deterioration of Inertia, Self Regulation, and Governor Response to the extent that the power systems engineering community is raising concerns about the impact of this deterioration on the reliability of our interconnections. In response to these concerns NERC has undertaken initiatives to monitor this deterioration to be prepared with measures to ensure that the reliability of the interconnections remains adequate.
For this monitoring to be effective, there is a need for a method for analyzing generation and load loss incidents on our interconnections to estimate on a continual basis the Inertia, Self Regulation, and Governor response displayed by our interconnections. To be useful, this method has to be sufficiently accurate without being too cumbersome to apply.
The purpose of these pages is to present such a method by applying it to real life disturbances on our interconnections that have resulted in serious frequency deviations from 60 Hz. This method is based on the use equations (1) to (5) below. For a derivation of equation (1) see the page "Frequency Deviation Equation".
