Physics-informed machine learning (PIML) has been emerging as a promising tool for applications with domain knowledge and physical models. To uncover its potentials in power electronics, this article proposes PIML-based parameter estimation method demonstrated by case study of dc–dc Buck converter. A deep neural network the dynamic models converter are seamlessly coupled. It overcomes challenge...

During the last years, different methods for identifying permanent magnet synchronous motor (PMSM) parameters have been developed. Such allow a better characterization of PMSMs, thus enabling control. This article presents novel PMSM parameter estimation method based on differential power factor due to harmonic distortion, which allows identification from data acquisitions representing entire t...

The power-generation capacity of grid-connected photovoltaic (PV) power systems is increasing. As output forecasting required by electricity market participants and utility operators for the stable operation systems, several methods have been proposed using physical statistical approaches various time ranges. A short-term (30 min ahead) method had previously multiple PV motion estimation. This ...

We introduce a new two-parameter lifetime model, referred to alpha power transformed inverted Topp-Leone, derived by combining the transformation-G family with Topp-Leone distribution. Structural properties of proposed distribution are implemented like; quantile function, residual and reversed life, Rényi entropy measure, moments incomplete moments. The maximum likelihood, weighted least square...

This paper proposes decentralized improved synergetic excitation controllers (ISEC) for synchronous generators to enhance transient stability and obtain satisfactory voltage regulation performance of power systems. Each generator is considered as a subsystem, for which an ISEC is designed. According to the control objectives, a manifold, which is a linear combination of the deviation of generat...

We revisit the power spectrum analysis of the complete sample of the two degree field (2dF) QSO redshift (2QZ) survey, as a complementary test of the work by Outram et al. (2003). A power spectrum consistent with that of the 2QZ group is obtained. Differently from their approach, fitting of the power spectrum is investigated incorporating the nonlinear effects, the geometric distortion and the ...
