ABSTRACT

This chapter presents the preliminaries of intelligent systems (IS) strategy application to power system stability analysis, systematically describing the principles, advantages, and process of constructing an IS for power system stability assessment and control. It discusses some most critical issues in its development and implementation stages. The advent of IS technologies provides an alternative and promising methodology for much faster and information-rich stability analysis. A sufficient stability database is paramount to the IS because, if the database is biased, unrealistic, or too small, the extracted knowledge will probably be useless. The variables characterizing the power system can fall into two categories: static and dynamic, respectively corresponding to pre- and post-fault environments. The IS can be combined with mature stability analysis tools, such as time-domain simulation (TDS). In such a condition, the IS could filter the ascertained cases and leave the pending ones to TDS.
