Power System Transient Stability Analysis Using the Transient Energy Function Method

Chapter 8Modeling Improvements in the TEF Method

8.1 Introduction

In the previous chapters the basic elements of power system direct transient stability assessment using the TEF method were presented. This included development of the transient energy function and its critical value, identifying the energy responsible for the separation of the critical generators from the rest of the system, the computational issues involved, and applying the TEF method to power system problems. In all this, a relatively simple (i.e., the classical) power system model has been used. In today’s power networks this simple model is of limited validity, even in analysis of first swing transients. To overcome this shortcoming, some improvements in the modeling of ...
