    Charge and discharge Batteries into grid?

    Keith, It's not a testing kind of lab. It's for demonstration. We have many people coming through from FERC people to members of congress. We use these demonstrations as a means to promote policy change etc. at many different levels. P.S. I was refering to shareholder owned utilities not...

    Hey Keith, Where do I pick up one of those simulators?

    Lightening Protection for a building

    Maybe his stuff is lightening and grounding out as it floats into the air. Sorry I couldn't resist. Pedant, that is a good word, are you a teacher? I mean damn you're pretty heady for a guy named Sparky. Oh and Tom, I might have made the same mistake, but not now thanks to Sparky.

    Charge and discharge Batteries into grid?

    Simple math says utilities figure out what it costs to provide the energy and then figure out how much to charge for it. Unless you're saying that utilities pay for the extra costs of peak demand out of their own pocket I don't really see your point. I realize that even after deregulation they...

    Charge and discharge Batteries into grid?

    This would also be useful for companies using a TOU rate on their own fleet of eletric vehicles. Peak shaving is a prime concern for maintaining reliability and maximum efficiency of existing infrastructure.

    Charge and discharge Batteries into grid?

    Are you saying utilities don't make more money when energy prices are higher, don't pass on all infrastructure costs and don't pay for power they use? They have energy reduction programs, but I believe those generaly mandated to them. Depending on what part of the country you are in getting...

    Charge and discharge Batteries into grid?

    Companies like BPL already do this kind of work in Demand Respose. They use wireless networks and CTs on individual circuits to monitor available and actual power shedding. I think all the technology exists its just start up that is hard because the network is not in place and there are too...

    Charge and discharge Batteries into grid?

    Dave, The software that controls how much and when your car is used for regulation resides inside the car. You input these parameters. Nothing could be done without you first allowing it through plugging your car in and opting in or out via the software. Are you worried that your power will be...

    Charge and discharge Batteries into grid?

    The cars would never be fully discharged. They would maybe operate in the 70% to 90% range. Because they are used for regulation they would be both sink and source. The net power required for regulation is around zero, but because power plants must now stay on standby to provide this power it...

    CT Metering Calculations

    Wow, sorry that was kind of dumb on my part.

    Charge and discharge Batteries into grid?

    Maybe spinning reserve was bad nomenclature they would really be used as a regulation resource.

    Charge and discharge Batteries into grid?

    " electric vehicles with bi-directional grid power capability are well-suited to providing regulation due to their ability to respond rapidly to power commands, and because the long term net energy requirement for regulation usually nets out to zero if the nominal generation level is set at...

    Charge and discharge Batteries into grid?

    http://www.acpropulsion.com/reports/V2G%20Final%20Report%20R5.pdf This website has a full study on how they will be used as spinning reserve. The idea is that the people providing the plugins will be so well rewarded for providing spinning reserve that they will be able to allow people to...

    Charge and discharge Batteries into grid?

    Does anyone have plans for building such a system? It will be used to demonstrate the effect of electric cars on the grid. They invision people just charging at night and using the cars batteries as a spinning resrve during the day. As I see it the crux will be building a synchronous...

    CT Metering Calculations

    "And if you're stuck with this meter and CT combination then your meter will indicate 1.5x whatever the true value is." I think the opposite is true. When your 200:5 ct is maxed out your meter will read 300 if it was previously calibrated to work with a 300:5 ct. So you would really divide by 1.5.
