Our research work and proposal
Our proposal is begun from the explanation on the next figure.The person who has seen a figure at glance and has understood it soon, (also the one except), please see the next.A business by DR (demand response) has also started in Japan already.It seems there is not many company that join the business of this demand response as the new electric power yet, but the demand response is one of key concepts of.”electric power system reform” Also in Japan, a wave of electric power system reform has come to surge ssteadily. What is the demand response? What is the important point of this business for the new electric power?
1.Advice of DR Aggregator business
To join this business,it is required to monitor the demand correctly and tocontrol.But it’s a linchpin in the linchpin to monitor this demand correctly for future electric power business.
(The following figure is copied in Aggregator recruitment of Hokkaido Electric Power Company at this summer just as it is.)
Also in this summer, Hokkaido Electric Power and Kyushu Electric Power recruited aggregator, and passed the peak of the tight electric power supply.(demand aggregator recruitment of Hokkaido Electric Power)
There are no certain ways of demand restraint except the demand response in the time of the peak of electricity demand. Please think. If the consumer who contracted to this aggregator was electric power correspondence as usual, maybe he was behaving in the direction that the peak of the electric power is pressed up conversely. Because that behave with the tendency to reduce more than the usual demand.
What is the DR Aggregator? When saying a player of the former electric power system,following 4 sector are included. (1) Generate electricity (2)Power system operation and market operation (3) power transmission and distribution (4) retail. But from now, the 5th player would carry out the important role. That is Aggregator.
“That is the sector which contributes to an electric power system “by restraining electricity demand and gets the consideration. Here, the saving electric power of the general enterprise itself is handling like generation capacity .
DR Aggregator concentrates electricity demand as the DR resource and sells it to the power company (system organization).
But even though why needed the troublesome business which restrains a demand?
(aggregator：the enterpriser who assembles and sells demand restraint)
※Hokkaido Electric Power wanted consignment contract of power demand reduction at the time of tightness of supply and demand of electric power in this summer.Hokkaido Electric Power Company is explaining by 3 concepts about the consideration. (aggregate charge, operation charge, contract unachievable adjustment charge)
- Aggregator charge have to pay in advance according to the possible electric power reduction (the contract reduction electric power) at setting the contract, in spite of an operation presence of demand.reduction.
- When operating demand reduction, the implementation charge will pay according to results of the reduction electric power Further, the upper limit value is set as the reduction electric power of results as a principle.
- In the case when demand reduction was performed and “the results of the reduction electric power was filled in”the contract reduction electric power, the contract unachievable adjustment charge is collected.
That’s because this demand response is most low cost adjustment power supply of the cost most.This demand response has functions not only as the capacity of the electric power (the electric power capacity) but also as ancillary service(frequency regulation).
Among these points, of course, all power plants have the function of (1) electric power , but concerning about functions of (2)capacity and (3) ancillary service, the power plant where gas turbine plant is usually flexible taked and power plant of renewable energy have not these two functions.
As the ratio of the renewable energy rises conversely, the adjustment power supply which is these two functions is becoming more important.DR aggregator achieves the function as this adjustment power supply.
In Hokkaido Electric Power and Kyushu Electric Power, from now on, this aggregator recruitment seems to be continued.Rather it’ll be increased.Because it’s certain to increase the ratio of the renewable energy rapidly from now on at Hokkaido and Kyushu.This means increasing in the importance of the adjustment power supply rapidly inevitably.This means increasing in the importance of the adjustment power supply rapidly inevitably.
But even if this DR makes the theory top effective, how is the equipment introduction cost of this DR?
When DR judged by the whole society, even if it’s certain that DR is very effective and that advantage exceeds the cost in an electric power system, the introduction cost of DR is very high and introducing enterprises have to bear all of it, the incentive of introducing DR is will not born.
Because the enterprise which applies for a DR program of Hokkaido Electric Power isn’t using the DR equipment introduced for the purpose of a DR aggregator application, that’s clear.
That was introduced ahead at other purposes by chance, it’s only that DR equipment originally is being used.
Then, what was made the DR equipment introduced at other purpose primarily in a destination?
It was introduced by consumer, it were the brownout purpose by peak cut and peak shift of the electric power. But since depending on a way of equipment introduction of this DR, it’s limited as aggregator busuness.The DR system itself has to be reasonable one and if the DR aggregator introduces a DR equipment only for the business purpose, it has to be profitable enough.
Our ODMS can answer such request, and the demand monitoring system with the enough function.
The thing what we want to emphasize one here is that DR has not only aggregator business but also the various shapes programt.And it’s said that DR is also important for the new electric power like being important for a power company of existence.Next that’s explained.
2.Renewable energy is able to increase more
The voice which should make more renewable energy spread early became loud in Japan after earthquake disaster in March, 2011.And immediately, fixed price buy system(FIT Feed-in Tariff)started and instantly solar energy generation exceeded the first schedule substantially When saying by the authorization amount, it reach 70 million kW even beyond a plan in 2030.It becomes the result to be hanged the reconsideration of a plan now due to increasing in only solar energy generation suddenly.
We are thinking to need reconsideration certain degree, but momentum of this renewable energy promotion not have to stop.Because there are no guarantees which the nuclear power plant can work easily like before the earthquake disaster.The energy self-sufficiency rate of Japan is low at only 6 % and it doesn’t pleasant also on the energy safety security.Moreover,CO2 reduction in problem of global warming is also international pledge.
But, even if renewable energy include an excellent power supply like variously as solar energy generation, wind power generation, small scale hydropower, biomass generation and
geothermal power generation.
Therefore, it isn’t strange that the voice comes out which say to make them develop with balance well using these advantages and features of the renewable energy power supply , .
But solar energy generation is low than the EU , it should still make them expand.
It isn’t the level to have to brake.
Now, the next chart figure shows the amount of electric power generation of the solar energy which shouldn’t look rather original. It is being visual done in real time at every moment so that it may sometimes change.The average amount of electric power generation every 30 minutes is recalculated every one minute, and the chart is indicating it.
When arguing renewable energy, the visualization of an environment additional value is becoming important.The environment is valuable, but unless giving the visible form, no one tries to pay a consideration.
Even if the new electric power declare “We offer the green energy.” on the home page, they may not be able to appeal for the electricity’s being the green energy really.How the environment value becomes visible at the environment advanced country EU is beating their brane out.
But this system isn’t just having only visualization of the amount of electric power generation for its object here.This generating electricity chart is generating electricity data of 1 minute unit, but the value of the renewable enerugy electric power is going to raise itself by this data.What kind of thing is that?
Solar energy generation chart
Now, it was seeing also having difficult problem for enormous volume introduction of renewable energy.The biggest problem here is the things of a charge acceptance to the system of a great deal of movement power supplies.The recognition that reform of an electric power system is also indispensable to this was deepening.Without electric power reform, any more expansion of renewable energy isn’t possible.This matter has been recognized by the world public, too.
How should do to accept this enormous volume unstable renewable energy to the power system?
This is also argued extensively at the EU because of the problem of the “flexibility” of the power system.At first, it is no difference in the “supply spare power” of the flexible gas turbine plant.However, it’s limited to raise the flexibility of the power system by the supply spare power only.The following 4 items are mentioned by the report of IEA (International Energy Agency).
- The power plant that control is possible (That is regarded as the usual supply spare power)
- The energy storage facility (mainly, it is electric power plant with pumped-up water)
- The coordination system line (it pointed the electricity dealings with other electric power areas, and it mean with foreign dealings at the EU.)
- Demand side management
The demand side management in the report is “DR aggregator” explained first.
More attention is “the coodination system line”.It means that it makes “smoothing” the instability of renewable power supply by “assembly” of unstable those energy at a wide area.The saying proper thing, but because this “make assemble” is performed as electricity dealings, grasping in real time of the renewable energy electric power generation becomes necessary and important.It’s becoming more important only grasping in real time but also the prediction of the renewable energy electric power.
By this predictability, it is because of receiving cost of coordition system becomes different substantially.When it’s the viewpoint for a new electric power side here to the imbalance problem of supply obligation of simultaneousness and commensurate of the electric power, this electric power monitoring in real time and prediction are expected that it’s effective by a reason.
Our ODMS can answer such request, and is the demand monitoring system with the enough function.
By the way, it should pay attention to give the power generation facility with pumped-up water to storage the electric power by a report of IEA.The lithium ion batteries argued in Japan aren’t argued.
Originally, those problems that were the expansion of the renewable energy ratio in the electric power, reform of electric power system and deregulation of the electric power were individual primarily.But these reform is related closely and is also promoted by synchronously at the EU as well as Japan.To say so, it’s because EU faces necessity of various electric power reform and has pressed for a solution during expanding renewable energy actually.
In addition, it’s clearer by the case EU preceded ,they have the recognition that expansion of renewable energy bring itself independence and activation of regional economic.By such reason, also in Japan, the attention of district creation by expansion of this renewable energy was collected and the trnd to make a pillar of district creation was just rising.The recognition spreads over the whole country level simultaneously already, and foundation of generation of electricity using the feature of the area has started with a small scale hydropower and biomass generation of electricity everywhere.It is the movement to make the area abundant by raising the self-sufficiency rate of the energy of the area.The national support is related largely, too.
That’s because it’s to raise the energy self-sufficiency rate of Japan consequently, and it’s a very good thing for Japanese energy security also.
We also feel the anxiety there slightly.Now, it has begun to move to area promotion by a small scale hydropower and biomass generation of electricity in the area.but the business is premised on “Fixed price buy organization” and the thought doesn’t seem to go ahead.Of course, it’ll be necessary to manage this now system enough.But this system depends on burden of the electric user and doesn’t continue eternally.So, we’re thinking that the renewable energy enterpriser have to work on mechanism making that like is being profitable without help as the business by ingenuity.
3. Simultaneous commensurate problem of the electric power which disturbs the new electric power Japan is in the midst of reform of an electric power system now
In April, 2016, full deregulation of power retailing is going to start as reform of the 5th electric institution In such inside, players of the electric power business called “the new electric power” more than 800 companies are born, they are going to offer new service and suggestion to the world and develop it.This thing, it itself is very wonderful, in 2016, it seems indeed to become the electric power system reform first year.
On the other hand, there is the obvious difference of the power between new electric power more than 800 companies and general electric enterprisers who are the power company of existence.
Therefore “asymmetric regulation” etc. is the reason which exists to a general electric enterpriser, but only such regulation is not enough, and of course the side of the new electric power is requested for being not waiting silently and going to do something.But even if it’s prepared at random freely, it’s insignificant.How can the new electric power have advantage to the power company of existence?
Let’s think about the meaning of the asymmetry of “asymmetric regulation” here.What is asymmetry between the general electric enterpriser and the new electric power? Asymmetry exists by all points in the present.For example there is the overwhelming difference in the amount of the electric power which can be put in a market.But I think that such “market power”can be correspondent fairly by the asymmetric regulation.Or, precisely,the reform of this electric power system doesn’t have the meaning.But the matter we make the problem isn’t the thing.
There is the different of obtained electric power information between the general electric enterpriser and the new electric power. We are thinking this is the problem.A general electric enterpriser grasps a supply demand situation of the electric power in real time.So it’s the reason which is doing load-following according to the demand of the electric power and is doing supply of electric power.
Although, the new electric power have supply obligation according to demand, the electricity ,but they don’t have the information of supply and demand on the electric power in the real time. Though it’s that, an excessively heavy penalty exists in an imbalance of the electric power. This is contradiction.We are thinking that this point should be cancelled.
By such reason, isn’t it the problem of the simultaneous same amount in the electric power that everybody of the new electric power can be disturbed most now? It’s obliged to achieve the simultaneous same amount when the electric power participate in the business as the new electric power.When the amount of electric power that is expected to sell couldn’t be supplied by the simultaneous same amount, the penalty is imposed.It’s the simultaneous same amount in 30 minutes in Japanese system.Its difference is less than the 3%, and this is the very severe restrictions.It’s forced to every new electric power now how to solve this problem.
Now, please see the following graph.A change figure of the electric power consumption of one firm.This is the graph of 30 minute unit and indicates one week change by one screen.This graph is utilized by demand monitoring systems for consumers of high voltage service and shows the enormous effect in the brownout action in the enterprise.And we were finding out that this system is also an indispensable tool for the new electric power.

4.virtual power plant
Thus, the electric power is similar graph between generation and of receiving of electricity.More this electric power data is being utilized as the chart added up.As I speak till here, there would be the person who has understand tightly.This data make possible to “make assembly” and “smoothing” in the group, as well as “predict” more.The renewable power plant decentralized is maked assembly and have the functions as a virtual power plant.
By the way, could you pay attention that I have emphasized the real time and 1 minute unit so far? The Japanese demand is 30 minute unit, and that’s handled by an electric power market as a unit of the conditional value.Saying even so, it is not good that 30 minute unit is fine for information of supply and demand on the electric power at all.It’s necessary that electric power data is at least 1 minute unit, I’d like to emphasize here once again.
5. Don’t you expand the circle of a balancing group?
We, by such study results, and, I’d like to support the electric power balancing group of the root level of the grass and networking.I’m convinced that our studies of “instant monitoring” system of the electric power , the prediction of its demand and and the prediction of the amount of electric power generation are very useful for that.Even though it’s the useful, if the cost of arranged system is so high that independence of the business is spoiled, it’s just insignificant.Though the new electric power was started with difficulty hard, if the reality became like an owner in a convenience store, it have to say mistaking of the means for the end.Our purpose is to plan for activation of local economy by raising the energy self-sufficiency rate of the area.
A system is used already, but we are going to add the improvement.for reform of future’s electric power system by advancing study.And we will also support well using IT for example the way to build net shop site and for information sending the blog building by using EC-CUBE cheaply and others.This is because the means to report information to a customer directly become indispensable.
We’d like to make renewable energy be widely used in Japan seriously as Japanese.But It have to stand up as a business for it.And to spread the regenerate energy, it have to correspond to reform of an electric power system also.The new electric power is an important player for spread the regenerate energy.We think that we are useful to everybody by all means, and the new business can be made together.
Everybody of the new electric power and everybody of promotion of renewable energy, we have concrete suggestion to you.
