Composite Approach for the Early Detection, Assessment, and Visualization of the Risk of Instability in the Control of Smart Transmission Grids

Abstract

The present chapter tackles the problem of determining and presenting the relevant information which can assist a power system operator in assessing the risk of blackout due to instability in a timely, efficient, and effective manner. Algorithmic approaches and numerical indicators that can help identify the instant status of the degree of operating reliability are also presented. Three concepts to detect, quantify, and visualize the risk of blackout are introduced and extensively illustrated with speedometer diagrams, stability trending charts, and snapshots taken directly from supervisory control and data acquisition (SCADA) system user interfaces.
