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

Largest blackouts around the world: Trends and data analyses
TL;DR: In this paper, publicly available data have been compiled into a dataset of large-scale blackouts that happened from 1965 to 2015, and a formula has been devised to filter the largest blackouts by equally weighting the number of people affected and the total restoration.

Réglage de la tension dans les réseaux de distribution du futur
TL;DR: In this paper, a methode de reglage de tension novatrice appelee OMD pour Optimisation Mixte Decouplee is proposed, which permet un controle optimal de la tension a l'interieur des parcs tout en assurant le maintien d'une consigne de puissance reactive or de tension au point de connexion avec le reseau.

Large-scale power system controlled islanding based on Backward Elimination Method and Primary Maximum Expansion Areas considering static voltage stability
TL;DR: In this article, a novel approach for separation of bulk power system into several stable subsystems following a severe disturbance is proposed, which reduces the huge initial search space of the islanding strategy to only interface boundary network by clustering the coherent generators and simplifying the network graph.

A Test bed dedicated to the Study of Vulnerabilities in IEC 61850 Power Utility Automation Networks
TL;DR: This paper presents the operational part, giving details on the power grid hardware-in-the-loop simulation and its importance in the understanding of cyber consequences on the global system, and preliminary experimental results showing consequences of a false data injection attack on a simple electrical architecture.

A circuit approach to fault diagnosis in power systems by wide area measurement system
TL;DR: In this paper, an analytic method for fault diagnosis, using the wide area measurement system (WAMS) and employing circuit rules, is developed, instead of conventional information about status of protective relays and circuit breakers, voltage and current phasors at different points of the power network after fault occurrence are utilized.

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.
