On-line dynamic security assessment using intelligent systems

Power system security assessment has traditionally been conducted using analytical techniques guided by human control. The conditions to be studied are forecast and deterministic studies conducted to establish the security and determine the need for remedial actions; humans normally play a significant role in the formulation of the input to the studies and also in the interpretation of the output. For security assessment in operations, on-line security assessment in which a snapshot of the system is captured and analytical engines are used to assess security in near-real-time has eliminated some of the uncertainty previously introduced by forecasting. However, it is still desirable to develop new technologies using artificial intelligence and intelligent control systems which can have the benefits of analytical analysis as well as exhibit human-like adaptability and decision making capabilities to assist in evaluating system security and providing control decisions
