Abstract: Due to an ever-increasing market penetration of plug-in hybrid electric vehicles (PHEVs), the charging demand is expected to become a main determinant of the load in future distribution systems. In this paper, we investigate the problem of controlling in-home charging of PHEVs to accomplish peak load shifting while maximizing the revenue of the distribution service provider (DSP) and ...

This paper examines the problem of optimizing the charge pattern of a plug-in hybrid electric vehicle (PHEV), defined as the timing and rate with which the PHEV obtains electricity from the power grid. The optimization goal is to simultaneously minimize (i) the total cost of fuel and electricity and (ii) the total battery health degradation over a 24-hour naturalistic drive cycle. The first obj...

Plug-in hybrid electric vehicles (PHEVs) that are driven and charged in ‘dirty’ power systems, with high penetrations of coal and other polluting generation fuels, may yield higher net emissions than conventional vehicles (CVs). We examine the implications of imposing a constraint on PHEV recharging that forces emissions from PHEVs to be no greater than those from a comparable CV. We use the Te...

Plug-in hybrid electric vehicle (PHEV) technology will provide substantial reduction in petroleum consumption as demonstrated in previous studies. Platform engineering steps including, reduced mass, improved engine efficiency, relaxed performance, improved aerodynamics and rolling resistance can impact both vehicle efficiency and design. Simulations have been completed to quantify the relative ...

Plug-in hybrid electric vehicle (PHEV) technology may reduce fuel consumption and tailpipe emissions in many mediumand heavyduty vehicle vocations, including school buses. The true magnitude of these reductions is best assessed by comparative testing over relevant drive cycles. The National Renewable Energy Laboratory (NREL) collected and analyzed real-world school bus drive cycle data, and sel...

Unified power flow controllers (UPFCs) are FACTS devices which can fulfil multiple power-flow control objectives, such as the need for reactive shunt compensation, phase shifting and series compensation. However, as they are quite expensive, they are not widely used. In this paper, the potential of a plug-in hybrid electric vehicle (PHEV) in a vehicle-to-grid (V2G) mode of operation using a PHE...

The battery charging system is a critical part of a plug-in hybrid electric vehicle (PHEV). The efficiency, charging speed, and cost of such chargers are crucial to the commercialisation of PHEVs. In this paper, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments. Their electrical stress, efficiency, c...

Plug-in hybrid electric vehicles (PHEVs) can become valuable resources for an electric power system by providing vehicle to grid (V2G) services, such as energy storage and ancillary services. We use a unit commitment model of the Texas power system to simulate system operations with different-sized PHEV fleets that do and do not provide V2G services, to estimate the value of those services. We ...

In view of the limitations of automated mechanical transmission (AMT) for plug-in hybrid electric vehicle (PHEV), as a scheme of new transmission system without synchronizer Electric-drive Automated Mechanical Transmission (EMT) was proposed. Taking use of the electric machines’ speed quick response characteristic, EMT uses active synchronous gearshift instead of the passive friction gearshift ...

Nucleotide sequence analysis and transposon 5 (Tn5) insertional mutagenesis indicate that the Escherichia coli gene pheR encodes tRNA(Phe) and not a repressor protein as previously reported. The coding region of pheR is identical to that of three other cloned tRNA(Phe) genes, pheU, pheV, and pheW. Multicopy plasmids carrying pheR, like those carrying pheU, pheV, or pheW, complement a temperatur...
