Rolling bearings are fundamental elements that play a crucial role in E-Z MOBILITY the functioning of rotating machines; thus, fault diagnosis of rolling bearings is of great significance to reduce catastrophic failures and heavy economic loss.However, the vibration signals of rolling bearings are often nonlinear and nonstationary, resulting in dif
The conservativeness of unit commitment models-based robust optimization (RO) depends on the modeling of uncertainty sets.This paper proposes a new two-stage robust security-constrained unit commitment (SCUC) model, which aims at minimizing the operating cost in the base scenario while guaranteeing that the robust solution can be adaptively and saf
