The vision of the Smart Grid includes the creation of intelligent electricity supply networks to allow efficient use of energy resources, reduce carbon emissions and are robust to failures. One of the key assumptions underlying this vision is that it will be possible to manage the trading of electricity between homes and micro-grids while coping with the inherent real-time dynamism in electrici...

For system operators, Congestion management is a difficult task as the market’s security and reliability are protected by this methodology. As magnitude of an electric transmission extremely dynamic, limits must be estimated much beforehand, in order to manage congestion issues at right time. Flexible AC systems (FACTS) used control voltage fluctuation adjusting system's real reactive power. A ...

Increased electric power consumption causes transmission lines to be driven close to or even beyond their transfer capacities resulting in overloaded lines and congestions. Flexible AC Transmission Systems (FACTS) provide an opportunity to resolve congestions by controlling power flows and voltages. Main focus in this paper lies on the Thyristor Controlled Phase Shift Transformer (TCPST). IEEE ...

Wireless network-on-chip (WiNoC) is considered as a novel approach for designing future multi-core systems. In WiNoCs, wireless routers (WRs) utilize high-bandwidth wireless links to reduce the transmission delay between the long distance nodes. When the network traffic loads increase, a large number of packets will be sent into the wired and wireless links and can...

This paper presents a novel optimization based methodology to allocate Flexible AC Transmission Systems (FACTS) devices in an attempt to improve the previously mentioned researches in this field. Static voltage stability enhancement, voltage profile improvement, line congestion alleviation, and FACTS devices investment cost reduction, have been considered, simultaneously, as objective funct...

Future power systems are expected to have distributed energy resources (DERs). A price-based operation (PBO), where dynamic prices are used as the control signal, can be an alternative scheme to address challenging operational issues in the future power systems. In this paper, a decentralized framework for optimal PBO using a feedback control mechanism is proposed to determine the nodal prices ...

during the last years, the concept of input congestion and technical ineff- ciency in data envelopment analysis (dea), have been investigated by manyresearchers. the motivation of this paper is to present models which obtain thedecreased output value due to input congestion and technical ineciency. more-over, we extend the models to estimate input congestion, technical ineciencyand output red...

a three month-old-male red deer calf (cervus elaphus maral) was examined post mortem for the cause of death in arasbaran preserved area in east azerbaijan in september 2006. the main history of the case was the lack of colostrum intake after birth. the necropsy 6 hours after death, revealed severe general congestion especially in lungs and visceral organs (liver and jejunum). the cut surface of...
