HILLA -Interactive Hot Water Factor (Giwhs) Add the bidirectional control to the water heating water, so that an aggregator of benefits or suppliers of third -party benefits goes out and turns on and turns on. This functionality transforms a fleet of hot water. To increase and reduce the base.GiwhsThey are currently the most economical form of energy storage.Expected answer, Arbitration, additional services or react to unexpectedDoor stabilization events.

The traditional distribution of the new hot water technology was a careful slow process, but hot water rental programs can accelerate this process considerably.Damhirschkuh) This prohibits water heater with electric resistance in more than 55 gallons. It has been proposed, but it must still be inserted into the code, and the industry is waiting for theDamhirschkuhDecision.

What is interactive water heating from the grid?

Most people think of their hot water from their hot water as a device that was designed exclusively to heat bath water or wash a basin full of dishes. However, hot water electric leaders can provide part of the storage of storage ofFaster, flexible, scalable and cheap energy.

Add bidirectional control to hot water with electrical resistance.GiwhsActivate an aggregator to service programs or third -party suppliers to turn off the devices quickly and repeated. The bidirectional control is a much more powerful tool than standard direct load control, with which only devices can be turned off as hot water: The derivation system is effectively transformed into a battery. The batteries provide electricity when the generation is low and the performance is absorbed when production is high. This helps modulate load energy.GiwhsIt cannot provide electricity, but they provide exactly the same functionality that invests this equation: it can modulate the load to follow the generation. At the general description times, the fleets can be activated by hot water. Subcalcalculation time can change to download the Pando loadand redistribute the current on the network.GiwhsIt can act as virtual plants to control the power of the network quickly and effectively.

Utility advantages

GiwhsAllow the supply company or the aggregator to postpone the loads, make the demand to save income arbitrating the wholesale current, to obtain income through additional services and maintain the stabilized network in case of unexpected events.

Traditional charge and demand change.Beyond the traditional demand, which releases charges in times of maximum requirements,GiwhsIt can be used to move loads and perform intelligent load control.GiwhsAround peak hours and smaller peaks, the load curve can turn during the day and at the same time keep the hot water supply.Illustration 1).

Arbitration of the wholesale current.Energy suppliers can calculateGiwhsIf the energy price is low and can deliver when the price is high, save money and its customers.

Additional services income.Service companies can also useGiwhsFor frequency or other services regulation. Frequency or only regulatory regulation is the adaptation of the second and second generation. Depending on the market, there may be considerable sales potential for regulation. More renewable energies are intermittent to the networkThe solar and wind energy, for example, has fluctuated by nature with the availability of sun and wind, which increases and immerses production unexpectedly. I am agreeing. Many characteristics are flexible enough to provide this service, but storageIt can do it very well.

The monetary value of frequency control depends on the transmission organization, which monitors the delivery of the high network voltage current and controls regional transmission organizations (NTA) that cover large interstate areas and independent systems operators (ISO)smaller geographical areas. Proports to frequency regulation a price much higher than the majority or ISO, which makes financial incentive for financial incentiveGiwhsMuch higher in the territory of this organization. For the PJM, an individual hot water ready for hot water at night (eight hours a day) can generate a frequency regulation of approximately 140 US dollars for income.GiwhsIn the PJM territory, the client can lead to annual negative energy costs. This means that customers can earn money offering this service, according to Steffes Corp.2012.Papel BrancoInteractive electric heat storage (obtained) water heating(Pdf) However, we did not see confirmation of these numbers.

Hophs hot water leaders (HPWHS) cannot provide frequency regulation, as well as the can of electrical resistance heaters, and are a great energy efficiency technology and efforts for efforts for the market participation marketDamhirschkuhAnd the energy star, the HPWH cannot be performed as fast and almost as fast as electrical resistance cutters cannot draw as electricity as the water from the electrical resistance.

Stabilization of the door.Perhaps one of the most valuable services thanGiwhsThe provision is the ability to react to network events in seconds. If a trip to the transformer or other unexpected event occurs,GiwhsLeave the supply company or the aggregator delivers or increase the load in seconds.

Advantages and additional implications.Not all places on the network are the same.GiwhsThey are more valuable for areas for sales companies, such as areas with excessive distribution resources, since they can reduce the main requirement, which can allow the supply company to postpone the distribution tax.

For the areas that have many renewable energy resources, supply companies or aggregators can consider a renewable warehouse, together with the original hot water tank and deliver renewable hot water when available. The tank uses a mixed valve to dilute the waterHot to reduce temperatures in hot water inside (DHW) before the water is delivered to the customer.

Lower energy storage

In one (nApril 2014 letter toDamhirschkuh(Pdf), Terry Boston, the CEO of PJM, said: "The storage of the electric water processor is the most effective form of available energy storage."GiwhsThere is approximately a cheaper size than most other technologies.Ferramenta Es-selectSandia National Laboratories shows relative costs to store hot water.Figure 2).

New control technologies

Two new hot water processor controls were introduced in the market, which took place especially for the interaction of the network.

The first solution is made by Steffes Corp.iote and uses a good tank and an external control box. Actually, the company is working on the integration of the control box in the hot water pioneer as an original equipment manufacturer solutionFactory Installation (OEM). The Steffes algorithm can control hot water., or may allow water to overheat in the tank, which doubles energy storage capacity. It is delivered to a Hawaiian field testElectric Co., which was documented in whichDEMAND Pages Management Programs Annual Change Report for Programs, Document No. 2007-0341(Pdf) Water overheating in the tank did not reduce the efficiency of the water case. This is because the water pilot essentially passed the same amount of time at lower normal temperatures, since it spent higher than normal temperatures, whatwhich caused efficiency to become a linen.

The second solution is offered by Sequentric, which developed an OEM control box that can be integrated into a hot water from the water. Technology does not need a mixed valve, since temperatures never exceed predetermined DHW values. The tank is naturally in layers, the utility or the aggregator have control over the initially cold water in the lower part of the tank. The controlled resistance element is used to heat this cold water of "makeup" at the standard temperatures of DHW. The client remains lost, the client remains in Einfach with standard functional water water.Figure 3).

In addition to individual hot water controls, an utility or aggregator needs a software service to add theGiwhsIn the controllable fleet. This software must pursue the load level (temperature) of individual hot water.CompartmentIt is not overloaded (which leads to temperatures higher than those planned) or the subject (which leads to the lack of hot water to the customer).

Both Steffes corp.bem as a sequencing, have their own software and can use their respective controls to offer the ability to control the fleet ofGiwhsA concurrent fleet aggregation service was developed together with the Battelle Memorial Institute of Service Logic. This offer can verify any type of hot water manufacturer, including standard models for electrical resistance models that are not designed for interaction for networks for networks.

Obviously, it is more important to satisfy customers with the proper supply of hot water. Bisher showed all the tests we know.

Until now, there is no negative effect on customers

With steffes, controlled with the Steffes software, the pilots showed no negative effects on the availability of hot water. In the Hawaiian electric field test, the field test was the first conclusion that "hot water was always available to the user final".

In the manufacturers, the standard electrical resistance water tests reported that they used the Service Logic and Battelle Memorial Institute software, the water temperature supplied on the upper edge of the tank was maintained consistent despite the temperature temperature fluctuations in temperature inThe lower part of the tank (tankFigure 4) However, we have not seen independent validations of these data.

Sequentric technology has been tested by the Institute for Electric Power Research and is now being used by Hawaiian Electric, but we still do not need to see the results of these studies.

To receiveGiwhsIn customer houses

Alternative business models, such as the supply company or third parties that offer a service instead of a product, can be advantageous. It is one third of this model, it can replace the existing hot water.CompartmentAt the time of failure.GiwhsAt a much faster rate than the previous technology market (Z. Predes Water Lesing has many advantages:

  • Hot water with failure can generally be replaced in less than 24 hours at no cost to the customer. Hot water lines.
  • The replacement of warm water is usually a larger warehouse tank that offers the customer a longer hot water duration than probably before.
  • If the hot water is lick, the insurance policy or the third -party insurance policy can cover damage instead of the owners.

A new technology standard was also developed that could simplify the distribution process. The standard standard for the association of consumption electronics 2045 is essentially a fiscal field that clicks on a standard compatible thermal water.Figure 5) .The value of this standard is double: you can take into account any communication technology (including WI -FI, mobile radio and radio frequency), which makes the infrastructure interface of the Public Services Network or theAGNOSTIC AGGRETOR.-TECHNICS TO CUSTOMERS) Relieve customers who install the complement as soon as the usefulness or aggregator and the client are willing to add the interoperability of the network.

What's happeningGiwhsNow?

Great River Energy, a Minnesota generation and transmission company, is currently reviewing around 70,000 hot water.GiwhsAt night, when the price of electricity is low, they save money and at the same time offer the same or aggregate companies that are currently reviewingGiwhsFor frequency regulation, although the PJM has tested and determined the strategyGiwhsThey could successfully follow the regulatory signal.

The biggest obstacle thatCompartmentThe market is currently a 2012DamhirschkuhTrial, which prescribes a great capacity output (more than 55 gallons) and an HPWHS supplement for 2015.DamhirschkuhNorms as response toDamhirschkuhsuggested a resignation system so that manufacturers can produceGiwhsMore than 55 gallons. However, the proposed resignation has not yet been approved.DamhirschkuhThe government authority requires that it is mentioned previously to accelerate its decision -making process and govern the renunciation system in the code. The state of the decision -making process is availableFederation's website.
