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

A Literature Survey on Different Loss Minimization Techniques used in Distribution Network
Avik Metia,Smarajit Ghosh +1 more
TL;DR: The commonly employed methods of loss reduction are capacitor placement, feeder reconfiguration, conductor grading, Distributed Generation (DG) allocation etc. as discussed by the authors, which is an important and well researched topic, many researchers proposed different approaches, they vary with each other by selection of tool for loss minimization and also in problem formulation.

Risk-Aware Service Routes Planning for System Protection Communication Network in Energy Internet
TL;DR: A novel risk-aware routes planning mechanism (RSRM) to reduce network risk as well as guarantee critical service performance of SPCN is proposed and results demonstrate that the method effectively reduces the balancing risk of the network and obtain the minimal total end-to-end delay in comparison with other algorithms.

Powering Los Angeles with renewable energy
TL;DR: The City of Los Angeles is nearly two thirds of the way towards its goal of generating a third of its electricity from renewable sources by 2020; cities around the world can glean valuable technical, economic and political lessons from its experience.

A combinational transfer learning framework for online transient stability prediction
TL;DR: Wang et al. as discussed by the authors proposed a combinational transfer learning framework to update transient stability prediction model in time-varying power systems, where convolutional neural network (CNN) is selected as the classifier.
Dissertation
The impact of inverter based systems on power grid stability
TL;DR: It is shown that serious grid instability leading to grid failure will occur under certain levels of inverter injected power, and that the level of grid-tied inverters injected power can be increased for certain inverter control loop designs such as virtual synchronous machine loops and also when additional technology such as synchronous condensers are employed.

Slow coherency-based islanding
TL;DR: In this paper, an analytical basis for an application of slow coherency theory to the design of an islanding scheme, which is employed as an important part of a corrective control strategy to deal with large disturbances.

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.

TL;DR: In this paper, the authors describe the major events that occurred as the blackout initiated and evolved and identify the technical causes characterising the different phases of the process, which led to the general blackout.

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.
