Abstract

Significant new generation additions, prompted by open access, may significantly change the small signal stability characteristics of a large power system. This paper analyzes such characteristics for the 4400 MW proposed generation additions in the Central and SouthWest North American Power System. Nonlinear time domain simulation is complemented by linear eigenvalue analysis for more insight and proper design of remedial measures. Power system stabilizers and a flexible AC transmission system (FACTS) device are used to improve inter-area damping. The analysis and design procedures, based on a new generation of tools, are outlined
