The 'Radio Network of Things' Can Cut Electric Bills (Video)

We all love 'The Internet of Things.' Now imagine appliances, such as your refrigerator and hot water heater, getting radio messages from the power grid telling them when they should turn on and off to get the best electricity prices. Now kick that up to the electric company level, and give them a radio network that tells them which electric provider to get electricity from at what time to get the best (wholesale) price. This is what e-Radio is doing. They make this claim: "Using pre-existing and near ubiquitous radio signals can save billions of dollars, reduce environmental impact, add remote addressability and reap additional significant societal benefits."

Timothy noticed these people at CES. They were one of the least flashy and least "consumer-y" exhibitors. But saving electricity by using it efficiently, while not glamorous, is at least as important as a $6000 Android phone. Note that the guy e-Radio had at CES speaking to Timothy was Scott Cuthbertson, their Chief Financial Officer. It's a technology-driven company, from Founder and CEO Jackson Wang on down, but in the end, saving money is what they sell. (Alternate Video Link)

For example if your furnace needs to run 30 minutes out of every hour to maintain the set temperature (and so do all your neighbors), then the smart grid can synchronize the furnaces to run every other house for 15 minutes, then run the other houses, etc. This will smooth the load the power company has to deal with without anyone having a decrease in service. It removes some of the spiky demand associated with the random effect of appliances cycling on-and-off at will. Excess capacity can be scheduled to improve service for everyone and reduce the peak design requirements.

      On a very large scale (like an entire city) the random distribution does take over and level itself. However on a smaller scale, like a subdivision or a neighborhood the spiky effects are quite evident -- approximately one-third higher than in a similar area with controlled demand. Why does this matter? One reason is that it allows the utility to spend less on hardware like transformers and wires, which keeps the billing rate low. It also reduces the chance of peak load failure of transformers and breakers during the peak air conditioning days, which have major expense of unplanned outages and emergency repair costs. It is so much cheaper for a utility to be able to set back AC units in an area of town where the transformer is dangerously overloaded than it is to do rolling blackouts or risk a catastrophic failure.

      "The furnace is one appliance that has a lot of flexibility in exactly when it runs - most of the time you can shift its runtime by 15 minutes (or longer) without a noticeable difference in comfort"

      Not to the degree that most would think. At least not using the PID controller algorithms I've worked with. As far as I know these are still generally used at the core of heating/cooling control systems. The basis for these algorithms actually dates back a couple hundred years to a ships officer deriving a method for a large ship auto-pilot system. He simply studied the techniques highly experienced crew members used to make course corrections in the dynamic environment of the sea.

      PID controllers remember historical data points so they know that running the furnace for y mins last time overshot by a large margin or leaving it off for x mins did so and they will decrease x or y respectively on the next cycle. If it's decreased too much it will increase again and so on until the target is reached and a sweet spot optimal adjustment is found. So on our two axis curve that overshooting and is jitter noise that diminishes as the adjustments become finer. That's all pretty straightforward.

      If you introduce a change the algorithm reacts to try to steer back to target and how aggressively it does so is tunable. Which is the tricky part. You want it to be aggressive enough to handle it when the temperature outside suddenly drops by 20 degrees in a couple hours but not to over react when a cool air current momentarily passes over the thermostat because someone walked in the door. The overall optimal tuning parameters are going to have to be some kind of compromise between the two. The tuning would obviously be dramatically different for the heating element in an oven than a furnace in a home.

      Those are the obvious parameters and limitations one could reason out without having the first clue about PID controllers. What might be less obvious is that there is nothing in the algorithm that knows if the furnace was actually on when it told it to be or even that it's a furnace. The algorithm assumes that the temps it's measuring on each cycle are the result of steering correction it provided and it's internal state is will be react with a more aggressive action on the next cycle until it hits it's max. That means it's going to overreact when the furnace does work and the longer it didn't, the longer it will take to dial back down and settle into a sweet spot. For one 15min interval that's probably a small matter on a slow moving system like home temperature. But for random 15 minute intervals many times a day, that is going to result in many overly aggressive cycles. If you plot the result on 2 axis it will be extremely jittery with lots of big swings to adjust. That is going to result in higher power consumption, not lower.

      My gas usage is roughly unchanged from week to week. The price of gas goes up - max was about $3.97/gallon.. The price of gas goes down- currently $2.17/gallon. So you are VERY wrong about energy price fluctuations. The amount of gas required to move me and my vehicle to work and back is very much the same. So it is not an illogical reaction. Demand for oil dropped, but not in proportion to the drop in price. The oil producing countries are mostly in OPEC which is a cartel that tries to control the supply of oil to meet their price goals. The price of energy has long been somewhat divorced from demand.

      Cable used to be a la carte. The cable company created bundles because they could charge for things you're not going to use - you could only watch one channel at a time. HBO or SHO used to be 15/month alone. Then HBO got bundled with SHO for $25/month, so you saved $5 if you got the bundle. The cable company is paying based upon number of subscribers with a volume discount - so the more subscribers to a channel the better the rate is for the cable company. So they get a better deal on their end whether you use the SHO or not and you are paying more for HBO than you would if you got it alone - but it's a great deal, amiright? IT just got worse and worse as time went on. Basic cable was priced at about 20/month which was CBS, NBC,ABC, PBS, the local college station if you had one, and TBS when it got started. The premium channels were HBO, SHO, Cinnemax, and The movie Channel each priced at about $15/month. So cable was a pretty good deal. You could get a movie channel and basic cable for $35/month. Now, there are hundreds of channels and mostly they are not any better than the stuff that was on forty years ago and the cost is WAY higher - but not when you figure price per channel. LAst time I had cable TV the price was $120/month for 140 channels of TV which included all the premium channels. That works out to $0.85/channel per month. Basic+ HBO was $35/month and that works out to about $6/channel per month. So the cost per channel per month is much less, and the price is much higher due to the volume of channels provided. But as the man said: "100 channels and nothing on." Mostly we look at TV and see two or three things we want embedded in a large pile of stuff we don't want for a large price and don't buy the value of each channel. Sadly, the option to just by the channel we want is not an option the cable company is willing to provide anymore, I think, because of all the deals they made with all of the channels. So wanting to buy only the thing I want and not pay for things I am NEVER going to use, is not the moral equivalent of "use less electricity." It is a value based reaction to the product being offered. It is the same reaction that music lovers had to the one good song but you have to buy the whole album issue. Really, bundling is good only when all of the items in the bundle are desired or useful.

      No, you've misread the summary. It's about the power company getting to choose where it buys the electricity from; that is, which power plants to use; to get the cheapest price. Unfortunately, they seem to have failed to notice that that is exactly what happens already.

      In the UK, for instance, the National Grid has had its own wired communications network running along the power lines for decades. This is used to monitor the power network and to command generation capacity to go on- and off- line. They already choose suppliers based on cost; the cheapest ones are used to provide baseload capacity. Units that are more expensive to run, but start up quickly, are called upon in response to peaks of demand.

      Similarly, there's nothing to stop an appliance manufacturer from monitoring the line frequency and using it to make decisions about whether to run or not. Such a device would only get a relative view of demand but, by logging changes over time, it would be possible to identify maxima and minima local to the logging time domain. With more memory, it would be possible to predict in advance, and make preemptive decisions (e.g. I don't need to turn on right now, but if I do then I won't need to run during the demand peak that's probably about to occur). Just make sure the algorithms are designed to avoid creating crazy oscillations in demand when a large number of identical appliances are connected to the grid. (i.e. they should not all switch on and off in sync with each other!)

      For the premium model, provide the ability to hook it up (wirelessly via a central receiver box) to a television antenna to gain access to the over-the-air electronic programme guide data. Then peaks and troughs in demand can be correlated with television programme titles and your appliance can learn to anticipate events that have been scheduled in advance. (A lot of electrical demand is strongly affected by broadcast events.)

      No centralised radio/internet/"smart" infrastructure is really required. I think it should be possible to design a completely distributed system with the correct emergent behaviour. However, centralising provides a means (a) to monetise it as a service (b) to make it easier to monitor and control people's behaviour by adding bi-directional communications or (c) to provide a communications channel for easily incorporating additional data sources into the operation of the system.

There is no point in turning them on and off base on the price of the power. It would make sense if I could store the energy at a cheaper point in time and use it later.

    Second, if everybody have that then the price will just average out and nobody will get to save any money. Or, worse, it will lead to price spikes because millions of people will turn on their electrical devices at the same time to catch the lowest power price.

    The idea that a smart grid leads to lower prices is just phantasy. If you want lower prices then build nuclear power plants, invenst in new technologies, invenst in building new power plants.

  49. This "invention" will bring down the grid by Anonymous Coward · · Score: 0

    This is an idea brought to you by people that do not understand statistics.

    Statistically, it is possible that every damn compressor will turn on at the same time resulting in such a peak current it will collapse every grid everywhere. But how likely is that? Statistics works and the power demand is about even. No spikes. Day in, day out same consumption. When there is an anomaly (generally weather vs. power lines) and power goes down for a large area, you'd notice that power restored progressively as it is known that lots of fridges will start running on every subgrid.

    Now, change appliances to be "smart". And how likely will it be that someone sends a "signal" to allow them to turn on ALL at the same time and bring down the grid? And fr what? To try to even out the miniscule unevenness in the demand curve?

    This is a dangerous "invention" that results in nothing positive. If you want to reduce the peak usage, that is already done by variable pricing for the large commercial sector. For consumers that can draw no more than 200A (at least around here!) from the grid, they balance the demand because of laws of large numbers - statistics.

    1. Re:This "invention" will bring down the grid by DamonHD · · Score: 1

      Goodness, that's rather offhand and completely wrong at lots of levels.

      Clearly there a peaks at national and supra-national level. Have a look at some of these for just one example:

      http://www.bmreports.com/bsp/b...

      Flattening demand would reduce costs of infrastructure that otherwise has to cope with unrestrained peaks; we already do this so it is only a matter of degree and where exactly we do it. Further, allowing demand to follow non-dispatchable load will also help make better use of renewables as well as cope with failure of conventional plant more gracefully.

      Also, different parts of the grid will have different problems, eg while the grid may be fine overall at a given moment one substation may be having a torrid time with its much smaller consumer sample, eg that may have a bunch of locals arriving off the same bus or train putting the water for a cuppa, or have a cable fault in one phase, or whatever.

      Further, sensible secure schemes will devolve as much as possible of the detailed timing to the appliance so that they cannot all be commanded to 'come on' or 'go off' at once but apply a randomisation algorithm much as Ethernet does for example.

      Just because you may have decided up front that there are no good solutions doesn't mean there aren't any. Some of the people that have them know a lot more about stats than you and I both, so can we at least accept that there are entire chunks of maths and computing that have interesting secure distributed randomised algorithms that deal with exactly these sorts of issues all the time?
