TLDR
In this article, the authors present the major conclusions drawn from the presentations and ensuing discussions during the all day session, focusing on the root causes of grid blackouts, together with recommendations based on lessons learned.Abstract:
On August 14, 2003, a cascading outage of transmission and generation facilities in the North American Eastern Interconnection resulted in a blackout of most of New York state as well as parts of Pennsylvania, Ohio, Michigan, and Ontario, Canada. On September 23, 2003, nearly four million customers lost power in eastern Denmark and southern Sweden following a cascading outage that struck Scandinavia. Days later, a cascading outage between Italy and the rest of central Europe left most of Italy in darkness on September 28. These major blackouts are among the worst power system failures in the last few decades. The Power System Stability and Power System Stability Controls Subcommittees of the IEEE PES Power System Dynamic Performance Committee sponsored an all day panel session with experts from around the world. The experts described their recent work on the investigation of grid blackouts. The session offered a unique forum for discussion of possible root causes and necessary steps to reduce the risk of blackouts. This white paper presents the major conclusions drawn from the presentations and ensuing discussions during the all day session, focusing on the root causes of grid blackouts. This paper presents general conclusions drawn by this Committee together with recommendations based on lessons learned.read more

Voltage Collapse Sensitivity in Power Systems
TL;DR: Simple, fast and efficient indices for analysing power system voltage stability and successfully predicting system voltage collapse are presented and four indices are proposed based on the gradient of generated powers with respect to load components producing sensitive voltage stability indications.

Self-healing in power systems: an approach using islanding and rate of frequency decline-based load shedding
TL;DR: In this paper, the authors proposed a self-healing strategy to deal with catastrophic events when power system vulnerability analysis indicates that the system is approaching an extreme emergency state, and a load shedding scheme based on the rate of frequency decline is applied.

Self-Healing in Power Systems: An Approach Using Islanding and Rate of Frequency Decline Based Load Shedding
Abstract: This paper provides a self-healing strategy to deal with catastrophic events when power system vulnerability analysis indicates that the system is approaching an extreme emergency state. The system is adaptively divided into smaller islands with consideration of quick restoration. Then an adaptive load shedding scheme based on the rate of frequency decline is applied. The proposed scheme is tested on a 179-bus, 20-generator sample system and shows very good performance.

The Italian 2003 blackout
TL;DR: In this paper, a fault on the Swiss power system caused the overloading of two Swiss internal lines close to the Italian border, which resulted in a very sudden loss of synchronism between the Italian system and the UCTE grids, causing the loss of the whole import.
