TL;DR: In this article, the authors examined the economic and policy implications of the National Football League (NFL) "blackout rule, which prohibits local television broadcast of games that are not sold out at least 72 hours prior to game time".
Abstract: In this paper, the authors examine the economic and policy implications of the National Football League (NFL) ‘blackout rule,’ a league rule that prohibits local television broadcast of games that are not sold out at least 72 hours prior to game time. The foundation for understanding and assessing the impact of the blackout rule is an analysis of attendance using data on games during the 1996–1997 National Football League season. Expanding on previous research, three separate components of attendance (season ticket sales, game day ticket sales, and game day noshows) are examined in detail. Accounting for the endogeneity of key variables, Tobit and Probit analyses are used to estimate and predict individual game attendance. These empirical estimates are then used as a vehicle to assess the implications of game day blackouts and the potential for public policy intervention. More specifically, the authors begin by estimating the impact of the blackout on game day attendance. Using these estimates, they asses...

TL;DR: In this article, the application of long-term dynamic analysis in studying frequency and voltage responses due to load and generation mismatches in isolated systems or during extension of the existing system in the restoration phase is presented.
Abstract: The problem of restoring a power system following a complete blackout is complex and multi-faceted, Many control actions have to be performed on time, while constraints such as power balance and system stability have to be carefully respected, In this paper, the application of long-term dynamic analysis in studying frequency and voltage responses due to load and generation mismatches in isolated systems or during extension of the existing system in the restoration phase is presented. Simulation results covering the main steps of the Hellenic power system restoration process following a recent total blackout are presented and discussed.

TL;DR: In this paper, a sequential importance sampling (SIS)-based strategy for cascading outage simulations and blackout risk analysis with solid theoretical foundation is proposed. But the proposed SIS strategy can significantly enhance the efficiency of simulations and reduce the estimation variance of blackout probability/risk compared with the traditional Monte Carlo simulation strategy.
Abstract: This paper addresses how to improve the computational efficiency and estimation reliability in cascading outage analysis. Under mild assumptions, we first formulate a cascading outage as a Markov model with specific state space and transition probability by leveraging the Markov property of cascading outages. Such a model provides a rigorous formulation that allows analytic investigation on cascading outages in the framework of standard mathematical statistics. Then, we derive a sequential importance sampling (SIS)-based strategy for cascading outage simulations and blackout risk analysis with solid theoretical foundation. Numerical experiments manifest that the proposed SIS strategy can significantly enhance the efficiency of simulations and reduce the estimation variance of blackout probability/risk compared with the traditional Monte Carlo simulation strategy.

TL;DR: In this article, a special protection scheme to prevent power system blackout due to a sequence of relay trip events based on phasor measurement units (PMUs) is proposed, and the strategy for determining the amount of remedial control actions is a proposed relay setting limited equal-area criterion for OMIB.
