Currently, electric taxis have been deployed in many cities of China. However, the charging unbalance in both temporal and spatial scale has become a rising problem, which leads to low charging efficiency or charging congestion in different stations or time periods. This paper presents a multi-objective coordinated charging strategy for electric taxis in the temporal and spatial scale. That is,...

Uncoordinated charging of large-scale electric vehicles (EVs) will have a negative impact on the secure and economic operation of the power system, especially at the distribution level. Given that the charging load of EVs can be controlled to some extent, research on the optimal charging control of EVs has been extensively carried out. In this paper, two possible smart charging scenarios in Chi...

According to a recently introduced theory (Spann, Zeithammer and Häubl 2010), a name-your-own-price retailer should benefit from charging prospective buyers a non-refundable bidding fee rather than providing the bidding opportunity free of charge. We use an incentive-compatible experiment to provides the first empirical test of the profitability of bidding fees. Confirming the theory’s qualitat...

We analyze future scenarios of integrating electric vehicles (EV) into the German power system under different assumptions on the charging mode. We use a numerical dispatch model with a unit commitment formulation which minimizes dispatch costs over a full year. While the overall energy demand of the EV fleets is rather low in all scenarios, the impact on the system’s load duration curve differ...

For an autonomous mobile robot, when the available power goes below a certain threshold, the robot needs to abort its current task and move towards a charging station to recharge its battery. The efficiency of an autonomous mobile robot depends significantly on the location of the charging stations. In this paper, we address the charging station placement problem for mobile robots in a controll...

Currently, when Electric Vehicles (EVs) are charging, they only have the option to charge at a selected current or not charge. When during the day there is a power shortage, the charging infrastructure should have the options to either shut off the power to the charging stations or to lower the power to the EVs in order to satisfy the needs of the grid. There is a need for technology that contr...

Charging mechanisms are needed to protect an integrated services network from arbitrary resource reservations and to create a funding mechanism to extend network capacity at the most desired locations at the expense of those users that actually use these resources. In this paper, we describe a charging model that can be embedded in the RSVP architecture. Our model is open and flexible in that i...

The rapid penetration of electric vehicles may lead to peak problems in a traditional grid so that some of the smart grid research is focused on charging strategies for electric vehicles. The charging problem is suitable for using a queue structure, and fuzzy queueing can be implemented for this purpose. This paper presents a fuzzy queueing based model, which can also control the power demand o...

In this paper we propose a layered framework for charging QoS-enhanced IP services with policy based configuration of its layers. As an example architecture we present our implementation Value Added IP Charging and Accounting Service (VIPCAS). We further concentrate on VIPCAS elements for policies and data exchange. As flexible data structure for exchange of accounting information, we propose t...
