Cover Story: As generally recognized, the G2V/V2G operations incorporated EV with utility grid and microgrid can effectively reduce fossil energy utilization. This paper develops an electric vehicle (EV) synchronous reluctance motor (SynRM) drive and its vehicle-to-grid (V2G) and vehicle-to-microgrid (V2M) bidirectional operations. A wind switched-reluctance generator (SRG) based microgrid is employed here as test plant.... View this paper.

Automated Probabilistic Analysis and Parametric Modelling of the Seasonal-Diurnal Wind Vector

Received: 14 April 2021;  Published: 25 June 2021;  doi: 10.21926/jept.2102027

Abstract

A refined and extended version of the Offset Elliptical Normal mixture model has been developed to parameterise the seasonal diurnal wind vector automatically. Automated using R scripts, the method eliminates any potential risk of confirmation bias posed by the manual supervision in the original method. Refinements to the method include the latest algorithms for clustering of Gaussian mixtures, with Bayesian regularisation to set the number of components and to limit the predisposition to overfi [...]

Abstract

A robust mathematical method for the characterization of damage in carbon nanotubes is presented the presentation here is limited to elasticity. In this regard, the second and third order elastic stiffnesses are employed. All this is based on damage mechanics. The hypotheses of elastic strain equivalence and elastic energy equivalence are utilized. A new damage variable is proposed that is defined in terms of the surface area. This is in contrast to the classical damage variable which is defined [...]

Abstract

Because lithium metal exhibits high specific capacity and low potential, it is the best candidate for fabricating anodes for batteries. Rechargeable batteries fabricated using lithium anode exhibit high capacity and high potential cathode; these can be potentially used to fabricate high energy density batteries (>500 Wh kg–1) that can be used for the development of next-generation electric vehicles.
