The need for deploying fast-charging stations electric vehicles (EVs) is becoming essential in recent years. This justified by the increasing charging demand and supported new technologies making EV chargers more efficient. In this paper, we provide a survey on models introduce data-driven approach with an optimization model fast-chargers both heavy trucks traveling through network of suburban ...

This paper presents the outcomes of a study summation supraharmonic (SH) currents from electric vehicle fast-charging stations (FCS), based on field measurement in an installation with four 350 kW FCSs. FCSs can contribute to SH emission, between 2 and 150 kHz, network their impact grid is quantified by components. Little known about SHs power hundreds kW, therefore this article aims understand...

The development of electromobility involves the electric cars charging infrastructure. increase number chargers poses new demands for AC power grid, especially in regard to its capacity delivering high peak power. As an alternative public urban electrified transportation systems (trams, trolleybuses, and metro) can be used supplying chargers. article discusses four options integrating with a tr...

The optical spectrum of monolithic Semiconductor Ring Lasers (SRLs) is measured simultaneously for both lasing directions with a grating-based OSA, in the regimes of bidirectional and unidirectional operation. In the unidirectional operation regime the SMSR is larger than 25 dB, and the directional extinction ratio (i.e., the ratio of the power emitted in the two opposite directions) is larger ...

this study attempts to investigate the effect of oil returns and external debt on the government expenditure in syria over the period 1970-2010. the johansen cointegration test showed that oil returns and external debt have a positive and significant long run relationship with government expenditure. the granger causality test indicates unidirectional short-run causality relationships running f...
