High congestion costs and new patterns, formed by intermittent renewable generation, demand for more efficient utilization of the transmission system. Transmission switching (TS) variable-impedance series FACTS devices are two technologies that provide such efficiency gains through controlling power flows. As system operators begin to utilize these tools, it is essential understand interdependence between them at various stages, as planning operation. This paper develops an optimal flow...
In recent years, renewable energy supply in the U.S. has increased dramatically, among which wind experienced largest growth. Since grid is not designed to handle high levels of intermittent generation, involuntary curtailment been implemented commonly many regional transmission organizations. Transmission congestion one main barriers, avoids full delivery produced energy. An obvious but extremely costly solution this problem building new lines. Alternatively, transfer capability over...
Severe weather is the primary cause of power outages in U.S. Despite availability forecast information, such data are not systematically integrated into operation models. This article proposes an framework to convert appropriate information for preventive during hurricanes so that induced by can be reduced. To achieve this goal, first, a structural model transmission towers developed estimate failure probabilities based on wind speed. These then within day-ahead security-constrained unit...
Biomass could substitute fossil fuels in heat- and power-generation projects to reduce air pollution greenhouse gas from many stages of the life cycle. The Nordjylland Power Station, one Denmark’s largest power plants, is a 100% coal-fired combined heat plant. To carbon dioxide emissions, this plant converting be biomass-fueled. However, biomass cannot assumed as an emission-free energy source, even though it has certain advantages terms sink capability. environmental impacts among various...
