In this paper we proposed a modeling method of the electrode lift controlling plant of a n ultra high power electric furnace and verified the accuracy of the proposed model by simulation an d field test. Keyword: ultra high power (UHP) electric furnace, electric lift device, electric lift control

Many perceive electric vehicles (EVs) to be ecoenvironmentally sustainable because they are free of emissions of toxic and greenhouse gases to the environment. However, few have questioned the sustainability of the electric power required to drive these vehicles. This paper presents an in-depth study that indicates that massive infusion of EVs to our society in a short time span will likely cre...

1. Introduction There is a growing demand for power semiconductors applied to motor drive inverters for electric vehicles (EVs) and hybrid electric vehicles (HEVs). Based on the results of the development and mass production of automotive power semiconductors, which require very high reliability and functionality, Mitsubishi Electric has developed the J-Series Intelligent Power Modules (IPMs) a...

This paper proposes a methodology for presizing the power of an electric vehicle traction motor. Based on the vehicle desired performances, the electric motor optimal power can be calculated. The final objective is to meet the design constraints with minimum power under the European urban (ECE-15) and sub-urban (EUDC) driving cycles. The power presizing methodology is validated through extensiv...

The increment integration of renewable distributed energies means the desired operation of the electric power system will significantly depend on the performance of primary energy. In this order, an integrated approach for mutual interaction between the electricity and natural gas systems has been considered for the purpose of ensuring optimal energy exchanging between the electric power system...

transmission network expansion planning (tnep) is an important component of power system planning. itdetermines the characteristics and performance of the future electric power network and influences the powersystem operation directly. different methods have been proposed for the solution of the static transmissionnetwork expansion planning (stnep) problem till now. but in all of them, stnep pr...

In this paper, we develop a static electric power supply chain network equilibrium model with known demands and establish the equivalence between the model and a transportation network equilibrium model with fixed demands over an appropriately constructed supernetwork. This equivalence yields a new interpretation of electric power supply chain network equilibria in path flows. We then exploit t...

A key obstacle to increasing renewable energy penetration in the power grid is lack of utility-scale storage capacity. Transportation electrification has potential overcome this since Electric Vehicles (EVs) that are not transit can provide battery as a service grid. This referred EV-Power integration, and could potentially be milestone pathway decarbonize electricity transportation sectors. We...

In this paper, the shape influence of piezoelectric beams including triangle, trapezoid, rectangle, inverted trapezoid, convex parabola, concave parabola, and comb-shaped (a combination of two triangular beams with a connector of 4 mm length) are addressed and analyzed by FEM. The analysis is performed for a bimorph piezoelectric beam. The analyzed parameters include the beam length, thickness ...
