DC fast charging (DCFC) and optimal placing of them is a fundamental factor for the popularization of electric vehicles (EVs). This paper proposes an approach to optimize place and size of charging stations based on genetic algorithm (GA). Target of this method is minimizing cost of conversion of gas stations to charging stations. Another considered issue is minimizing EVs losses to find neares...

As fuel price continues to rise and retail sales of decrease, the profits gas station owners will continue decline if they cannot accurately identify manage loss meet compliance requirements. For site who operate small medium-sized stations, it is even harder survive in increasingly fierce competition with big franchised do not stop loss. Many factors links can lead a service due special physic...

Abstract The article presents a hydraulic hydrogen compression solution designed to serve as booster compressor. It can be adapted changing parameters of the inlet pressure and allows stabilising accumulation process in high-pressure storage. main results this study were obtained using numerical model developed explore thermodynamic processes that occur during hydrogen. modelling was carried ou...

A new electrically driven gas booster is described as an alternative to the classical air-driven boosters known for their poor energetic efficiency. These are used in small scale Hydrogen storage facilities and refueling stations vehicles. In such applications overall energy count of significance must include efficiency compression stage. The proposed system uses electric motor instead pneumati...

Centrifugal compressors are used in a large number of different compression applications. This tutorial addresses applications for centrifugal compressors in the upstream and midstream sector, such as LNG compression, refrigeration, pipeline compression, compression for gas injection, gas lift, gas gathering, export compression, air compression, and others. The focus is on the specific compress...

Crop straw gasification technologies are the most promising biomass gasification technologies and have great potential to be further developed in China. However, the commercialization development of gasification technology in China is slow. In this paper, the technical reliability and practicability of crop straw gasification technologies, the economic feasibility of gas supply stations, the ec...

This paper investigates the influence of voltage dips on large electric driven gas compressors (EDC) considering a typical application in the oil and gas industry. Voltage or power dips are electric disturbances encountered in EDC which are mainly caused by faults in the electrical grid and might last for durations up to 150ms. For gas compression applications, the loss of driver torque often p...

extended abstract 1. introduction high traffic volume is one of the most common problems of urban transportation in metropolises. the increase in the number of vehicles in case of not having necessary predictions also enhances the demand for fueling in places where mostly are unable to respond to such needs. site selection of public facilities is an instance of policies of local governments wit...
