The integration of wind power requires the power system to be sufficiently flexible to accommodate its forecast errors. In the market clearing process, the scheduling of flexibility relies on the manner in which the wind power uncertainty is addressed in the unit commitment (UC) model. This paper presents a novel risk-based day-ahead unit commitment (RUC) model that considers the risks of the loss...
Image mosaicing has been collecting widespread attention because it can automatically construct a panoramic image from multiple images. Among previous methods, homograph-based methods are the most accurate in the geometric sense. This is because these methods use planar projective transformation, which considers perspective effects as a geometric transformation model between images. We propose an...
The dynamical theory of chaos is the new analysis method of study on the exchange rate undulation in the foreign exchange market. In order to study the chaos behavior of the Euro exchange rate, this paper put the purchase price of the RMB to the Euro as the sample and analyzes the nonlinear character of the Euro exchange rate. This paper figures out the Hurst exponent by the R/S analysis and confirms...
This paper presents a technique to evaluate unreliabilities and responsibilities of power market participants such as Gencos, transmission network and customers in a restructured power system. An optimal power flow (OPF) model subject to market and network constraints is used to determine load curtailment, generation re-dispatched and reserve dispatched. Reliability and economic indices for market...
