TL;DR: In this article, a Grey Wolf Optimizer coordinated with pattern search algorithm is used for solving the security smart grid power system management under critical situations. But the main objective of this proposed planning strategy is to prevent the practical power system against blackout due to the apparition of faults in generating units or important transmission lines.

TL;DR: In When the Lights Went Out, this article, Nye views power outages in America from 1935 to the present not simply as technical failures but variously as military tactic, social disruption, crisis in the networked city, outcome of political and economic decisions, sudden encounter with sublimity, and memories enshrined in photographs.
Abstract: Blackouts-whether they result from military planning, network failure, human error, or terrorism-offer snapshots of electricity's increasingly central role in American society. Where were you when the lights went out? At home during a thunderstorm? During the Great Northeastern Blackout of 1965? In California when rolling blackouts hit in 2000? In 2003, when a cascading power failure left fifty million people without electricity? We often remember vividly our time in the dark. In When the Lights Went Out, David Nye views power outages in America from 1935 to the present not simply as technical failures but variously as military tactic, social disruption, crisis in the networked city, outcome of political and economic decisions, sudden encounter with sublimity, and memories enshrined in photographs. Our electrically lit-up life is so natural to us that when the lights go off, the darkness seems abnormal. Nye looks at America's development of its electrical grid, which made large-scale power failures possible and a series of blackouts from military blackouts to the "greenout" (exemplified by the new tradition of "Earth Hour"), a voluntary reduction organized by environmental organizations. Blackouts, writes Nye, are breaks in the flow of social time that reveal much about the trajectory of American history. Each time one occurs, Americans confront their essential condition-not as isolated individuals, but as a community that increasingly binds itself together with electrical wires and signals.

TL;DR: Cumulative line trips from real blackout data have portions consistent with these branching process models introduced, and initial calculations identifying parameters and using a branching process model to estimate blackout probabilities during and after the blackout are illustrated.
Abstract: We introduce branching process models in discrete and continuous time for the exponentially increasing phase of cascading blackouts. Cumulative line trips from real blackout data have portions consistent with these branching process models. Some initial calculations identifying parameters and using a branching process model to estimate blackout probabilities during and after the blackout are illustrated.

TL;DR: In this paper, the authors identify the sequential failures of receiving station components under a severe earthquake, which progressively degrade the power network performance, potentially leading to a network blackout and estimate quantitatively direct cost of damage, emergency repair and restoration, and duration of power interruption.
Abstract: Dealing with the transmission network of electric power systems, this paper identifies the sequential failures of receiving station components under a severe earthquake. Such failures progressively degrade the power network performance, potentially leading to a network blackout. Hence, in this paper, these components are incorporated into the network systems analysis taking their seismic vulnerability into consideration in the form of fragility curves for the evaluation of the network performance under seismic conditions. Specifically, most critical to the operation of transmission network, transformers, disconnect switches, circuit breakers and buses are integrated into the systems analysis, exploring the possibility of progressive failures of these components. The scenarios of these component failures can make it possible to estimate quantitatively direct cost of damage, emergency repair and restoration, and duration of power interruption and attendant economic losses and societal disruption.

TL;DR: In this paper, the authors present the control strategies to be used in such a system to deal with islanded operation and to exploit the local generation resources as a way to help in power sys-tem restoration after a general blackout.
Abstract: A low voltage distribution network with large amounts of small sized dispersed generation can be operated as an isolated system in certain conditions. This paper presents the control strategies to be used in such a system to deal with islanded operation and to exploit the local generation resources as a way to help in power sys- tem restoration after a general blackout. A sequence of actions for the black start procedure is identified and it is expected to be an advantage for power system operation in terms of reliability as a result from the presence of a very large amount of dispersed generation.
