Operation of wind power generation in a large farm is quite challenging in a smart grid owing to uncertain weather conditions. Consequently, operators must accurately forecast wind speed/power in the dispatch center to carry out unit commitment, real power scheduling and economic dispatch. This work presents a novel method based on the integration of empirical mode decomposition (EMD) with arti...

Abstract We introduce a new generalized family of nonnegative continuous distributions by adding two extra parameters to lifetime distribution, called the baseline twice compounding power series distribution. The family, series-power has serial arrangement parallel structures, which extends Marshall and Olkin structure. Four special models are discussed. A mathematical treatment is provided, in...

the renewable energy resources such as wind power have recently attracted more researchers’ attention. it is mainly due to the aggressive energy consumption, high pollution and cost of fossil fuels. in this era, the future fluctuations of these time series should be predicted to increase the reliability of the power network. in this paper, the dynamic characteristics and short-term predictabili...

Residuals are frequently used as a diagnostic tool for verification that a time series model fits to data. In the cases when the series is nonnormal and/or the model is nonlinear, the squared residuals and squared values of the series are taken into account. In our paper asymptotic formulas for the mean value and variance of the corresponding sample corre­ lation functions are calculated. Small...

Locally asymptotically most stringent tests for autoregressive against diagonal bilinear time series models are derived. A (restricted) local asymptotic normality property is therefore established for bilinear processes in the vicinity of linear autoregressive ones. The behaviour of the bispectrum under local alternatives of bilinear dependence shows the danger of misinterpreting skewness or ku...

Positively charged: We look back at the developments of 2021 and give a glimpse to what our readers authors can expect in 2022. The past few years have been very exciting for field electrochemical energy storage. Batteries particular become an essential technology achieving carbon neutrality as well key component next-generation transport renewable solutions. It has real pleasure witness rapid ...
