Telecommunications carriers suffer large-scale outages that impact hundreds of thousands of subscribers by the improper deployment or operation of otherwise faulttolerant designs. This paper gives examples of such outages in telecommunications signaling, transmission, and power systems. In spite of seven years industry tracking of largescale outages at the national level, the survivability of t...

Power quality problem causes a misoperation or failure of end user equipments. Distribution network, sensitive industrial loads and critical commercial operations suffer from outages and service interruptions which can cost financial losses to both utility and consumers. In India the use of electronic loads is increasing very fast and the gap between demand and the supply have made the reliabil...

The power system becomes more severe under contingency conditions. In general, the contingencies may be outage of transmission lines or generators. To identify the effect of outages on system security, the contingency analysis is one of the analytical tools. The congestion on a system must be manages using generation rescheduling and with the proper control of the compensation equipments. The t...

Nuclear power plants must be regularly shut down in order to perform refueling and maintenance operations. The scheduling of the outages is the first problem to be solved in electricity production management. It is a hard combinatorial problem for which an exact solving is impossible. Our approach consists in modelling the problem by a two-level problem. First, we fix a feasible schedule of the...

ue to the expansion of power systems there is a challenge of real time monitoring and control by placing important parameters at various points for efficient functioning of the power system. There can be drastic changes during hourly load fluctuations, component outages, or network switching. In such conditions, the inclusion of predicted values could degrade the power system state estimation h...

Transition from traditional power grid into a smart grid involves collecting and processing a large amount of data from generation, transmission to consumer level. Data collected at each level differs considerably in terms of the parameters under observation and frequency of collection, satisfying the 5 Vs (volume, velocity, variety, value and veracity) requirements of big data. In this paper, ...
