We consider the scheduling of deferrable charging demand for plug-in electric or hybrid-electric vehicles (PEVs/PHEVs) in the smart grid such that the grid is operating within the safety charging threshold, and as many as consumers/users are satisfied by the end of a finite horizon (e.g., 8pm6am). Given that the charging profiles of PEVs/PHEVs are not constant and have a (truncated) prescribed ...

Compared with the traditional slow charging loads, random integration of large scale fast charging loads will exert more serious impacts on the security of power network operation. Besides, to maximize social benefits, effective scheduling strategies guiding fast charging behaviors should be formulated rather than simply increasing infrastructure construction investments on the power grid. This...

For service providers online charging of composite services is necessary in order to manage financial risks of service delivery in multi-domain environments. At service level, inter-domain composite services consist of one or more service components, e.g. access service, IMS communication service or content service, delivered by different service providers. The 3rd Generation Partnership Projec...

Wireless rechargeable sensor networks (WRSNs) consisting of sensor nodes with batteries have been at the forefront of sensing and communication technologies in the last few years. Sensor networks with different missions are being massively rolled out, particularly in the internet-ofthings commercial market. To ensure sustainable operation of WRSNs, charging in a timely fashion is very important...

Of all materials, silicon has the highest capacity to store lithium, and is being developed as an electrode for lithium-ion batteries. Upon absorbing a large amount of lithium, the electrode swells greatly, with a volumetric change up to 300%. The swelling is inevitably constrained in practice, often leading to stress and fracture. Evidence has accumulated that the swelling-induced stress can b...

The BGP routing protocol uses a mechanism called Route Flap Damping [13] to limit the impact of connectivity instability to any individual sites. Although it is believed that this damping mechanism contributes to the stability of global Internet routing, the exact effects of damping has not been thoroughly examined in a large scale network setting. Previous work [8] has shown that damping can b...

The charging method of lithium-ion batteries used in electric vehicles (EVs) significantly affects its commercial application. This paper aims to make three contributions to the existing literature. (1) In order to achieve an efficient charging strategy for lithium-ion batteries with shorter charging time and lower charring loss, the trade-off problem between charging loss and charging time has...

The rise of electric vehicles brings a number of challenges for our infrastructure and energy security. Waraich (Waraich et al., 2009) demonstrates that bad choices of charging times made by the owners of electric vehicles (EVs) or plug-in hybrid electric vehicles (PHEVs) can lead to severe problems for the electric grid due to peak loads. Coordinated charging decisions controlled by a centrali...
