Price effect analysis and pre-reseravtion scheme on electric vehicle charging networks

Abstract

<p>This paper investigates the price effect to the charging demand coming from electric vehicles and then evaluates the performance of a pre-reservation mechanism using the real-life demand patterns. On the charging network in Jeju city, the occupancy rates for 3 price groups, namely, free, medium-price, and expensive chargers, are separated almost evenly by about 9.0 %, while a set of chargers dominates the charging demand during hot hours. The virtual pre-reservation scheme matches electric vehicles to a time slot of a charger so as not only to avoid intolerable waiting time in charging stations systematically but also to increase the revenue of service providers, taking into account both bidding levels specified by electric vehicles and preference criteria defined by chargers. The performance analysis results obtained by prototype implementation show that the proposed pre-reservation mechanism improves the revenue of service providers by up to 9.5 % and 42.9 %, compared with the legacy FCFS and reservation-less walk-in schemes for the given performance parameter sets.</p>

Models of improved multilink reverse charging network by utilizing the bit error rate QoS attribute

“…One pricing scheme that deals with charging [11] back to user whoever utilize the other network is called reverse charging scheme [12,13]. Reverse charging is applied for electrical devices [14][15][16], even vehicles [17,18] and can be formulates as probabilistic mathematical modelling [19]. Currently, the extensive use of wireless network make ISP attempts to set up new pricing plan based on reverse charging (internet reverse charing-IRC) scheme in wired and wireless network [20].…”

Improved incentive pricing-based quasi-linear utility function of wireless networks

“…Network management is considered in critical state that every scheme regarding the pricing strategy should be maintained effectively. Internet pricing also should include the incentive for users maintaining the network [8]- [10]. Then, the requirement to have some mechanism to give user' incentive to upgrade the profit [11]- [16].…”
