Abstract

A new era of transportation has experienced electrification and undergoes notable changes in the last few decades. The concern about environmental friendly technology carries almost a huge expansion prospect to electric vehicles (EVs). Whereas plug-in hybrid electric vehicles (PHEVs) are recognized as a feasible term in the line of vehicular technology in the smart electric grid to lessen the dependency on fossil fuels and greenhouse gas (GHG) emissions related to conventional vehicles (CVs). The development of vehicle-to-grid (V2G) strategies establishes win?win situations for the PHEV participation without additional infrastructure cost, reduction of generation, operational and PHEV user cost, reduction of environmental pollution. Together with the expansion of the smart grid technologies, the V2G power allocation problems need to be addressed. More originally, this chapter measures substantial, though often overlooked, social barriers to the wider use of PHEVs (a likely precursor to V2G) and implementation of a V2G transition. This chapter has given an idea that the only important barriers facing the greater use of PHEVs and V2G systems are technical. Instead, it provides a broader assessment situating such ?technical? barriers alongside more subtle impediments relating to social and cultural values, business practices, and political interests. Thus, this research study recognizes probable socio-technical obstacles towards widespread adoption of V2G in smart grid and governs that if sustainability problems affect consumer decision to adopt V2G to charge their PHEVs. The current study delivers valuable understanding about the perception among technology fanatics associated with knowledge expansion and improved fortified to sort out the numerous alterations among V2G and PHEVs. Finally, the outcomes of this chapter can guide policy makers to implement V2G technology successfully. Moreover, the chapter illuminates the policy implication of such barriers, which emphasizes what policy makers need to achieve towards V2G technology adoption in smart grid environment while integrating electric vehicles engineering with consumer preference. ?

Abstract

the awareness of energy security and global warming is increasing, alternative technologies are being developed such as electric vehicles. In addition, the integration of a more sustainable energy system with renewable resources put a lot of pressure on the electricity system in terms of regulation power. This thesis has investigated and developed proposals of business models with electric vehicles, which by their construction can raise value for both customers and electricity companies. The development of the business models have been done using a model, which was based on the complexity of the frequency control market, the charging of vehicles and the behavior of the drivers. The proposed models address two types of customer segments; business and private customers. In addition, applying a perspective that includes active and non-active customers has segmented these further. Based on the assumptions in the thesis, the most promising area of interest is the non-active business customer, in this case, a car pool. This proposal was based on the simulation results together with an analysis of advantages and disadvantages with active and non-active customers. This proposal assumed that customers preferred to be non-active in order to maintain flexibility and freedom, which could be studied further by customer surveys.

These initiatives will enable acceptably fast charging of EVs. The proposal has been designed and implemented within the Endesa Novare Vehicle to Microgrid project. As a first stage of the project, the charge/discharge process has been emulated before it will be developed in a real device. The emulation consists of two main parts: (i) an electric vehicle and its battery management system emulated by a microcontroller, and (ii) a charging/discharging device emulated by a computer application. Both parts communicate via CAN bus as it is done in existing protocols. The proposed control flow for charging and discharging and the results of the emulation are presented. Moreover, in order to be able to manage charge and discharge processes according to power network operator, a data model for both electrical vehicle and charging/discharging device according to standard IEC 61850-7-420 is also proposed.

Abstract

Batteries of Electric Vehicles (EVs) and Plug-in Hybrid Electric Vehicles (PHEVs) have a large potential not only to provide energy for the locomotion of these vehicles, but also to interact, in dynamic way, with the power grid. Thereby, through the energy stored in the batteries, these vehicles can be used to regulate the active and the reactive power, as local Energy Storage Systems. This way, EVs can contribute to help the power grid to regulate the active and reactive power flow in order to stabilize the production and consumption of energy. For this propose should be defined usage profiles, controlled by a collaborative broker, taking into account the requirements of the power grid and the conveniences of the vehicle user. Besides, the interface between the power grid and the EVs, instead of using typical power converters that only work on unidirectional mode, need to use bidirectional power converters to charge the batteries (G2V - Grid-to-Vehicle mode) and to deliver part of the stored energy in the batteries back to the power grid (V2G - Vehicle-to-Grid mode). With the bidirectional power converter topology presented in this paper, the consumed current is sinusoidal and it is possible to regulate the power factor to control the reactive power, aiming to contribute to mitigate power quality problems in the power grid. To assess the behavior of the presented bidirectional power converter under different scenarios, are presented some computer simulations and experimental results obtained with a prototype that was developed to be integrated in an Electric Vehicle.

Abstract

The paper presents results of a study on the dynamic response of Electric Vehicle’s (EV) when participating in frequency control of an islanded system. The following cases were considered: when there is no EV performing frequency control, when the EV participates in primary frequency control and when the EV participates in both primary and secondary frequency control. Different parameters are tested in various combinations, and their influence on frequency deviation as well as power and energy provided by the EV with vehicle-to-grid (V2G) capability is shown."br/""br

Abstract

The Parker project sought to experimentally validate that contemporary series-produced electric vehicles (EVs), capable of V2G, are ready to participate in a number of advanced grid services. In such services, the timing, size and direction of power and energy exchanged between the EV battery and grid is controlled as to support either a single building, the local neighborhood or the regional power system. Vehicles purposely designed for such services are referred to as grid integrated electric vehicles (GIVs). The field of research, describing how GIVs may be used to actively support the power system, is called Vehicle&ndash Grid Integration (VGI).The purpose of this paper is to present how the Danish Parker project has systematically categorized a range of grid services, collected in a service catalog, and then illustrate state-of-the-art EVs ability to support such services through experimental validation. Results are presented for three different tests performed in Parker marginal emission factor charging, frequency containment reserves and a performance test for controlling power setpoints. The ultimate aim of this paper, and the Parker project, is to promote the GIV concept so that it may inform the design and capabilities of present and future EVs, EV supply equipment (EVSE) and communication standards.
