Electron Sandwich Doubles Thermoelectric Performance

Conceptual drawing of the superlattice in which spread electrons are confined to a narrow space to enhance thermoelectric conversion.

Researchers more than doubled the ability of a material to convert heat into electricity, which could help reduce the amount of wasted heat, and thus wasted fossil fuel, in daily activities and industries. Researchers from Hokkaido University and their colleagues in Japan and Taiwan have improved

Evaluation Method for the Impact of Wind Power Fluctuation on Power System Quality

The left figure is an example of time series of fluctuation of power generation outputs. The right figure shows the histogram of the frequency of corresponding power fluctuation. When we can assume mild fluctuation as illustrated by the red line, modeling with normal distribution is acceptable. However, wind power generation fluctuation contains abrupt changes as illustrated by the blue line. Consequently, the corresponding histogram has slowly-decaying heavy tails, which represents the extremal outliers.

Abrupt changes of wind power generation output are a source of severe damage to power systems. Researchers at Kyoto University developed a stochastic modeling method that enables to evaluate the impact of such phenomena. The feature of the method lies in its significant computational effectiveness in comparison
