How Electric Vehicles Interact With a Smart Power Electricity Network – Vehicle to Grid

Description:

Vehicle-to-grid technology involves drawing unused power from the car into the smart grid. V2G, which is also known as vehicle-grid integration (VGI), can help the energy grid supply electricity during peak hours. It can also create an extra power source when weather-dependent renewable energy sources are not available. – PowerPoint PPT presentation

What is Vehicle to Grid (V2G)?
  • Vehicle-to-grid technology involves drawing
    unused power from the car into the smart grid.
    V2G, which is also known as vehicle-grid
    integration (VGI), can help the energy grid
    supply electricity during peak hours. It can also
    create an extra power source when
    weather-dependent renewable energy sources are
    not available.

WHAT DO I NEED TO CONSIDER BEFORE DECIDING TO
CONNECT MY VEHICLE TO THE GRID?
  • Firstly you have to have an electric car which
    can be charged by a standard electricity outlet.
  • The second thing you will want to do is determine
    some basic driving habits i.e. if you drive
    almost your entire vehicle range to work and back
    every day, then there is unlikely to be much
    energy left over to swap between your battery and
    the grid, which makes setting up V2G a little
    redundant

5
  • Having decided that V2G connectivity is possible
    and feasible, you will need to look at the right
    products on the market to help you achieve this.
    I.e. which inverter should be used and which
    electricity trading contract will suit your needs
    the best?
  • If you decide suddenly that V2G is not good for
    you, how can you get out of an otherwise more
    expensive contract?

6
  • Once these basic items have been checked off the
    list, it is time to call up your utility and
    start the process of applying for V2G. You can
    then purchase a suitable inverter which allows
    you to feed back into the grid (this will be
    similar if not identical to the type of inverters
    used on solar PV grid connected power supplies).
    Of course you will have to decide what sized
    inverter to go for.

WHY IS VEHICLE TO GRID (V2G) GOOD?
  • Vehicle to Grid applications have a number of
    benefits for all sorts of businesses and
    stakeholders. Vehicle to Grid (V2G)
  • Empowers the home consumer to make sensible
    choices about when they use their electricity
    through smart metering
  • Saves the consumer money in the long run through
    effective electricity management

8
  • Is green! Every time you supply the grid with
    electricity during the yearly peak energy demand,
    you are reducing the need to upgrade the
    electricity network with more transmission lines
    and generators
  • You are helping to bring electric vehicles (EVs)
    onto the market
  • You are reducing your carbon footprint! This is a
    big ones these days
  • The electricity company can save money and reduce
    their unit electricity prices, or reduce the need
    to increase them

9
  • Reduce the amount of electricity transmission
    line needed. I.e. the car transports the
    electricity to where it is needed.
  • Cuts down on the amount of fuel stations required
  • Reduces our addiction to foreign oil through the
    accelerated introduction of electric vehicles and
    ability to replace fossil fuel generation with
    renewable energy generation.
  • Allows more sustainable energy and renewable
    energy to be introduced onto the electricity
    grid, as electric vehicle batteries can now act
    as a buffer to intermittent generation.

10
  • The last point is an important one. Traditional
    transmission networks are struggling to cope with
    large percentages of intermittent renewable and
    sustainable energy generation, as electricity
    generation from these sources is largely
    dependent on the elements. Therefore to have the
    ability to store electricity somewhere is
    important. In many countries power utilities are
    approaching this by pumping water up a hill and
    regenerating during peak times (60 efficiency)
    or storing hydrogen formed by electrolysis
    underground ready for re generation (40
    efficiency). Storing electricity in batteries is
    a much higher efficiency (60 90) however is a
    little costly.

11
  • Vehicle to grid systems also work very well as
    storage mechanisms and are likely to play this
    role in the future as more electric vehicles hit
    the market. How soon we will see such networks
    will largely rely on the countries commitment to
    renewable and sustainable energy sources, as well
    as the abundance of wind, sun and wave energy.
    Although many companies claim to have a green
    lining, short term economics of such projects
    still remains the number one driver for the
    introduction of such technology.

12
  • The advantage to the end consumer who is running
    a vehicle to grid system is the savings in
    electricity for essentially hiring out the
    storage space in their electric car battery. So
    as we can see, it is definitely a win-win
    situation for many as it not only reduces the
    stress on our electricity transmission and but
    also generation networks, allows more sustainable
    energy to be placed on the system with lower
    carbon emissions, but also saves the end user
    money whilst making electric vehicles more
    affordable.

13
  • It also weans us off our foreign oil addiction
    through the cost effective introduction of
    electric vehicles, a topical issue as we approach
    peak oil status around the world.
