This paper focuses on the impact of extreme weather on power system outages. Extreme weather condition impacts of interest are listed, including both direct and consequential events. Their impact on power system outages are discussed, concerning both blackouts and component failure. Prospects for estimating weather condition impacts on the frequency of blackouts and on equipment and system fail...

although our religious doctrines have given special importance to the execution of legal punishments and penalties for their conventional outcomes, the execution of legal punishments or their suspension in the age of occultation of the infallible imam (a.s.) has been one of the controversial issues in jurisprudence, to the extent that it has created two conflicting fronts; one, a group of disti...

A model has been developed to study the global complex dynamics of a series of blackouts in power transmission systems [1, 2]. This model has included a simple level of self-organization by incorporating the growth of power demand and the engineering response to system failures. Two types of blackouts have been identified with different dynamical properties. One type of blackout involves loss o...

Fifty percent of college students who drink report alcohol-induced blackouts, and alcohol abusers in general put a heavy burden on the medical care system. Using data drawn from a randomized, controlled alcohol intervention trial at five university sites, our study quantified the costs of visits to emergency departments by college students who experienced blackouts from drinking alcohol. Of 954...

Radar is a very important sensor in surveillance applications. Near-space vehicle-borne radar (NSVBR) is a novel installation of a radar system, which offers many benefits, like being highly suited to the remote sensing of extremely large areas, having a rapidly deployable capability and having low vulnerability to electronic countermeasures. Unfortunately, a target detection challenge arises b...

The blackout risk in power systems is difficult to estimate by actual probabilistic methods because they usually neglect, or do not properly consider, the dependencies between failures and the dynamic evolution of the grid in the course of a transient. Our purpose is therefore to develop an integrated probabilistic approach to blackout analysis, capable of handling the coupling between events i...

Blackouts result from cascading failure in transmission power systems. The typical development of a cascading failure can be split in two phases. In an initial slow cascade phase, an initiating contingency triggers a thermal transient developing on characteristic times much larger than the electrical time constants. This transient increases significantly the likelihood of additional contingenci...
