An adaptive mesh refinement procedure is presented in order to address efficiently low-frequency electromagnetic problems with the unstructured partial element equivalent circuit (PEEC) method. A posteriori error estimator based on an equilibrated energy criterion proposed, which means that two...

Advances in medium voltage direct current (MVDC) technologies and the penetration of extended MVDC systems are still significantly hindered by lack adequate (DC) switching equipment. The fundamentally different fault behavior case a DC fault, compared to faults alternating (AC) systems, with regard characteristics development currents their interruption make dedicated test procedures necessary....

As the solar PV harvesting energy system are becoming more important sector of renewable day to day, improving efficiency module and reducing cost modules receiving attentions manufacturers. Design interconnection ribbons is one main focus for developing reliability modules. In last decade, new designs ribbon have been introduced, however, there still a need optimize their configuration geometr...

The article investigates the detrimental effect of nonuniform and uniform crack distributions over a solar cell in terms open-circuit voltage ( ${{\bm{V}}_{{{\bf oc}}}}$ ), short-circuit current density notation="LaTeX">${{\bm{J}}_{{{\b...

<p>A quick, reliable, and accurate fault location approach is essential in underground power systems protection. Being the most optimistic research topic of electrical systems, this article presents an optimized algorithm for multi-end cables using travelling waves. Existing algorithms based on wavelet theory have fewer reliability accuracy issues that raise error to location. The propose...

<abstract> <p>The trend is shifting from internal combustion engines (ICEs) to battery electric vehicles (BEVs). One of the important joints tabs busbar connection. Aluminum (Al) and copper (Cu) are among common materials for tab manufacturing. A wide range research shows that laser welding a very promising technique. It can enhance module's safety reliability owing its unique prope...

This paper proposes a new adaptive controller for the robust control of a grid-connected multi-DG microgrid (MG) with the main aim of output active power and reactive power regulation as well as busbar voltage regulation of DGs. In addition, this paper proposes a simple systematic method for the dynamic analysis including the shunt and series faults that are assumed to occur in the MG. The pres...

For Utilities, each substation is regarded as an asset. Managing of assets one domains Asset Management including Life Cycle Costing (LCC) a decision-making criterion. However, LCC criterion should be applied on entire taking into account all the potential cost influences for purpose achieving effective management. management process observed within larger context and more focused risk manageme...

An electric arc furnace (EAF) is known as nonlinear and time variant load that causes power quality (PQ) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. One of the most important problems to study the EAF behavior is the choice of a suitable model for this load. Hence, in this paper, a probabilistic three-phase model is proposed base...
