The model for non-Abelian field topology for the multilayer fractional quantum anomalous Hall device

open access: yesFrontiers in Physics, 2022
From the recent empirical discovery of the quantum anomalous Hall effect (QAHE), the interaction of the particle with spin–orbit coupling (SOC) plays an essential role in the cause of the QAHE, which includes three terms: external, internal, and chiral ...

Benefits of spatio-temporal modelling for short term wind power forecasting at both individual and aggregated levels [PDF]

open access: yes, 2017
The share of wind energy in total installed power capacity has grown rapidly in recent years around the world. Producing accurate and reliable forecasts of wind power production, together with a quantification of the uncertainty, is essential to ...

Combining hydro-generation and wind energy biddings and operation on electricity spot markets [PDF]

open access: yes, 2006
Wind generation is growing rapidly in all the world, especially in Europe. The power produced by this kind of generation is difficult to predict and the predictions are not very accurate. In most systems these imbalances are costly.

A low leakage current (Co, Mn, Ta)-SnO2 varistor tailored by doping with chromium for power grids

open access: yesResults in Physics, 2020
A SnO2 varistor which was prospected to be used in ultra-high voltages grids as an overvoltage protection element was developed. The SnO2 varistor was doped with Cr to improve the comprehensive electrical properties. The optimal electrical parameters are

No-load cutting-in control of the doubly fed induction generator based on grey prediction PI control

open access: yesEnergy Reports, 2021
The traditional method of stator flux oriented PI control of the doubly fed induction wind generator (DFIG) no-load cutting-in is easy to implement under ideal conditions, but in the actual project with high frequency of wind speed change, the feedback ...

Market Power and Technological Bias: The Case of Electricity Generation [PDF]

open access: yes, 2006
It is difficult to elminated all market power in electricity markets and it is therefore frequently suggested that some market power should be tolerated: extra revenues contribute to fixed cost recovery,facilitate investment and increase security of ...
