Description

  The present invention relates to a control device, a control method, and a computer program.

  An electric power company supplies electric power generated at a nuclear power plant, a hydroelectric power plant, a thermal power plant, etc. that it operates to a user site. Electric power companies usually have power plants generate more power than the final demand at the user site, aiming for a smooth power supply. This power generation is generally said to be 30-40% higher than the final demand. During normal times, about 30% of this is a power generation loss.

  At present, the total annual cost of power generation / distribution / power supply at a Japanese power company can be estimated at approximately 13 trillion yen. About 30%, or about 4 trillion yen, corresponds to the power generation loss. In other words, there is a power loss market of about 4 trillion yen.

  Meanwhile, power storage devices such as laminate type lithium ion batteries, solar power generation devices, and power generation devices such as wind power generation devices are spreading to user sites. Attempts to use such power storage devices and power generation devices efficiently have been proposed (see, for example, Patent Document 1).

  In the system described in Patent Literature 1, the power generation margin can be reduced by discharging the power storage device at the user site during a period in which power demand and supply are tight. In addition, in order to obtain power demand forecasts, power usage schedules are collected from each user site.

  If the use of power at the user site is as planned, the technique described in Patent Document 1 can further level or reduce the power generation amount at the power plant. However, since the user is basically not obligated to use the power as scheduled, there are not a few user sites that use the power in a manner different from the schedule.

  Hereinafter, the same or equivalent components, members, and processes shown in the drawings are denoted by the same reference numerals, and repeated description is appropriately omitted.

The inventor has the following recognition.
Currently, there are many large-scale power plants in Japan, including thermal power plants, nuclear power plants, hydroelectric power plants, and pumped-storage power plants. These generators are balanced by increasing or decreasing the amount of power generation according to the load (demand for electricity) of the factory and each household consumer. If some kind of failure occurs in some generators, or if an excessive load is generated in the network of the transmission network, the balance between supply and demand is lost, which can cause power outages. Therefore, power plants and transmission / distribution networks in Japan have many surplus power generation facilities (sufficient buffers) that exceed the original demand power generation capacity, thereby reducing the risk of power outage.

  In addition, the generator in operation also controls the output of the generator for 24 hours in order to cope with delicate frequency fluctuations, but the control of the combustion chamber is much more delicate than the control of the generator. Since nuclear power plants are not good at starting / stopping control, they must always maintain a high variable operating rate. Power plants that use oil and coal as energy resources are relatively poor at fine control (primary energy once burned, such as coal, cannot be extinguished).

  And often these large power plants generate electricity at locations far away from consumers. In order to avoid transmission loss, power companies use an alternating current method, sublimate to ultra-high voltage and perform high-voltage power transmission, and when customers approach, they reduce pressure and distribute power to low-voltage customers. Primary energy such as oil, coal, and natural gas has an essential problem that about 2/3 of the original energy is lost when it is converted into secondary energy called electricity (that is, power generation) It cannot be said that high efficiency is achieved from the viewpoint of energy saving and saving. Although the combined gas turbine generator, which has been attracting much attention recently, has a power generation efficiency of more than 50%, there is still a problem that there is almost half of the shipping power loss.

  On the other hand, regarding the use of electric power, it is time for the customer side to revise the conventional electric power operation. There is a need for eco-friendly operations that are always conscious of energy saving and power saving, and not only strictly pursue waste on the power plant side, but also a self-evaluation of excessive power usage, and there are limited resources. It is required to have a consciousness of being.

  Therefore, in light of the various circumstances and impacts of the recent Great East Japan Earthquake, and the problems inherent in these legacy power generation systems, the role and character of large power plants will gradually be downgraded, It is expected to become smaller and smaller. In the future, there will be more power plants that use renewable energy instead of the conventional primary energy conversion type. In order to increase the efficiency of energy use, surplus electricity can be reused as a buffer at any time. Is likely to be carried out at each key point. Rather than large-scale and gradual control by conventional large-scale power plants, it is necessary for small and medium-sized power plants that demand high efficiency to dynamically respond to customers' power needs in detail. . Of course, ICT (Information and Communication Technology) technology will also be adopted as a new player in these controls.

  There are various types of energy-saving and power-saving actions that customers can participate in, but as a new effective energy-saving and power-saving action, the concept of “reserving power on the customer side” can be raised (for example, see Patent Document 1). In order to support detailed operation on the power plant side, the fact that the power plant side can always acquire information on when and how much electricity is used by the customer side is a very effective operation for realizing delicate energy saving. It appears to be. When the detailed operation plan report of each consumer reaches the power plant side, the power plant side can perform the minimum power generation with the best specifications according to the demand. DR (Demand Response) aggregator (see Non-Patent Documents 1 and 2, for example) etc., to achieve such a role, dynamically uses the detailed information reported from the customer side and dispatch without waste. It will carry electricity.

  However, it is recognized that the reservation system alone may not be sufficient in actual operation. In order to minimize the discharge loss of fine micro power generation and subdivided storage batteries, it is necessary to monitor and control the power operation in real time for each customer who judges whether or not the service is operating as scheduled. It becomes. In order to realize such operations, it is important for the supply side to grasp in real time what is happening to consumers, such as how they are using electricity and whether they are actually operating as scheduled. come.

  In addition, if small and medium-sized power plants are installed in various locations, more precise voltage / frequency control will be required for demand response than before. The closer contact points with customers mean that supply operations will become more critical, and it is essential to ensure real-time and interactive information in the information on power fluctuation factors. Let's go.

  In other words, in addition to the power reservation system, the latest information on the customer side that increases the fluctuation range of power usage, such as whether the customer has gone out, returned home, or went to bed, is directly acquired and seamlessly notified to the power supply side With the system according to the embodiment, it becomes possible for the first time to start the generators that have been dispersed and to discharge the subdivided storage batteries at the correct timing. Depending on the case, energy saving / power saving operation for discharging / charging control of a storage battery installed on the customer side may be performed.

  On the other hand, there is an idea that performance data using electricity can be acquired from a smart meter. However, the actual data acquired from the smart meter cannot accurately recognize “the latest convenience or schedule of using electricity” on the customer side. The actual data is only the result information. The supply side determines whether or not power usage fluctuations will be performed as scheduled in order to properly maintain the standby and idling conditions necessary for voltage and frequency adjustment at the timing when large fluctuations in power usage occur at the consumer. I want a "live" signal. For example, a reservation system by a consumer can visualize the power usage status on the consumer side to some extent by referring to the performance data from a smart meter. However, since the final demand trend on the most recent customer side cannot be seen accurately only by referring to the actual data, the supply side standby on the supply side is conscious of the remaining margin as before, and it is loose with a margin in idling state. Easily fall into response (power generation, frequency control).

  To give a specific example, the customer stays at home and uses power even though the planned outing time of the customer has arrived (the standby power mode time is originally used in the “reservation” information) Think of the case) That is, consider a case where actual operation different from “power reservation” is performed. The power adjustment / supply side such as the DR aggregator is in a position to supply power to consumers, and is continuously supplied and maintained according to the actual power needs required of the consumers.

  A case where the supply side is troubled by the judgment at this time is a case where the customer goes out with a long delay in going out time. The power adjustment / supply side who does not know that they have gone out, even if the actual data from the smart meter indicates that the power consumption is decreasing (standby power supply mode), “It may still be at home and be used immediately. "It may be," he will be forced to control the power generation equipment that maintains a margin for the electricity that cannot be used.

  As another example, there is a case in which the schedule is changed suddenly and the remaining electricity is used at home even though a reservation is made for “going out all day” on a holiday. Even if the supply side can acquire the demand data from the smart meter, it is impossible to determine how long it will continue to be used. In addition to this, when returning home earlier than the scheduled return time, or when returning home later than the scheduled return home time, the supply side may always be forced to operate in consideration of the advantages. If it is a legal entity, it can be even more serious. The effect of errors in power reservation and actual operation related to start of work, breaks, stop of work, and holidays associated with production activities in each company with larger power usage capacity than each household is large.

  In this way, when the uncertainty of the user's behavior enters, it may become ambiguous what the reservation is for and the meaning of the reservation definition may fade. The difference between the reservation and the actual data acquired from the smart meter may cause confusion on the power plant side and DR aggregator side. As a result, there is a possibility that the power generation loss is not much different from the conventional legacy dispatch power system. Therefore, it is important for the reservation system to know exactly the attitude and state of whether or not the customer is actually trying to execute as reserved.

  Based on these matters, in order to complement the power reservation system in one example, the control device according to the embodiment is intended to acquire the timing (real-time home information) when the fluctuation range of power usage from a consumer occurs. It is a system equipped.

  FIG. 1 is a schematic diagram showing the configuration of the power supply system 2. The power supply system 2 includes a data center 4, a power plant 6, a first user site 8, a second user site 10, a third user site 12, a fourth user site 14, and a network 16 such as the Internet. And a power distribution network 18.

  The power plant 6 is operated by an electric power company, and power generated by nuclear power generation, thermal power generation, hydroelectric power generation, pumped-storage power generation, geothermal power generation, wind power generation, and the like is supplied to each user site 8, 10, 12, 14 via the distribution network 18. Supply.

  The user site is a unit of power supply contract. The user site may be a detached house, a condominium, a building, a factory, or the like. Each user site 8, 10, 12, 14 is supplied with power from the power plant 6 based on a contract with the power company. Those skilled in the art will appreciate that the number of user sites is not limited to the example shown in FIG.

In the power supply system 2, a plurality of different power usage patterns are defined for the user site. For example, when the user site is a general household such as a detached house or a condominium, the following three usage patterns are defined.
(1) A non-sleeping pattern at home, which is a power usage pattern when a householder is at home and is not sleeping.
(2) Absence pattern, which is a usage pattern of power when a householder is absent.
(3) A sleeping pattern that is a power usage pattern when a householder is at home but is sleeping.
In addition, about the average usage-amount of electric power, it becomes a non-sleeping pattern at home >> a sleeping pattern> an absent pattern.

When the user site is a building or factory, the following three usage patterns are defined.
(1) An operation pattern that is a power usage pattern when a factory or a building office is in operation.
(2) A leave pattern, which is a power usage pattern when a factory or a building office is closed.
(3) A break pattern that is a power usage pattern in a break period of a factory or a building office.

  Hereinafter, the case where the user site is a general home will be described. However, the technical idea according to the present embodiment can be applied even when the user site additionally or alternatively includes another type of site. Those skilled in the art who have touched the specification will understand.

  The data center 4 includes a control device (not shown in FIG. 1) according to the embodiment. The control device may be a server or the like, and is managed and operated by the DR aggregator. The control device determines an amount (hereinafter referred to as a planned power generation amount) to be generated by the power plant 6 on a target date (hereinafter referred to as a target date) for which a power generation plan is planned, and determines the power plant 6 before the target date. Notify At this time, the control device collects the schedule of the power usage pattern on the target date from the users of each user site, and calculates the planned power generation amount based on the collected schedule.

  The control device receives a notification indicating switching of the usage pattern from the user of each user site on the target day. The control device determines in real time the difference between the actual usage pattern of the user site determined from the presence or absence of notification and the planned usage pattern. When the number of user sites whose actual usage pattern differs from the planned usage pattern increases more than the reference, the control device determines that the planned power generation amount after several minutes to several hours should be changed. When it is determined as such, the control device appropriately corrects the planned power generation amount and promptly notifies the power plant 6 of the corrected planned power generation amount.

  Each of the user sites 8, 10, 12, and 14 has solar power generation devices 8a, 10a, 12a, and 14a and power storage devices 8b, 10b, 12b, and 14b. The solar power generation devices 8a, 10a, 12a, and 14a are power generation devices configured by a known solar power generation technique. The power storage devices 8b, 10b, 12b, and 14b are continuously charged from the solar power generation devices 8a, 10a, 12a, and 14a, respectively. That is, the power storage devices 8b, 10b, 12b, and 14b are charged by private power generation. The power storage devices 8b, 10b, 12b, 14b themselves or a home server or smart meter (not shown) connected to the power storage devices 8b, 10b, 12b, 14b is connected to the control device installed in the data center 4 via the network 16.

  Each of the power storage devices 8b, 10b, 12b, and 14b is connected to the power distribution network 18 and, when instructed to discharge, the user site to which the self belongs and other users connected to the user site through the power distribution network 18 Supply to the site. In addition, when there is an instruction to prohibit discharge, the power storage devices 8b, 10b, 12b, and 14b do not discharge during the instructed period. The power storage devices 8b, 10b, 12b, and 14b, or the home server and smart meter, issue a discharge or discharge prohibition instruction to the power storage devices 8b, 10b, 12b, and 14b based on command information received from the control device via the network 16. .

  FIG. 2 is a block diagram illustrating functions and configurations of the control device 100 according to the embodiment. Each block shown here can be realized by hardware such as a computer (CPU) (central processing unit) and other elements and mechanical devices, and software can be realized by a computer program or the like. Here, The functional block realized by those cooperation is drawn. Therefore, those skilled in the art who have touched this specification will understand that these functional blocks can be realized in various forms by a combination of hardware and software.

  The control device 100 calculates the scheduled power generation amount from the power demand forecast on the target date before the target date, and collects the user's trends on the user site in real time on the target date to schedule the power demand. A real-time processing unit 104 that determines whether or not the vehicle passes, a user information holding unit 106, a schedule information holding unit 108, a scheduled power generation amount holding unit 110, and a point processing unit 130 are provided. When it is determined that the real-time processing unit 104 is not as scheduled, the real-time processing unit 104 corrects the scheduled power generation amount and notifies the power plant 6 of the correction.

  FIG. 3 is a data structure diagram illustrating an example of the user information holding unit 106. The user information holding unit 106 includes a user site ID that identifies a user site, an IP address of a home server, a smart meter, or a power storage device included in the user site, a user ID that identifies a user of the user site, a password, The actual usage pattern at the current time on the user site and the eco point are stored in association with each other.

  FIG. 4 is a data structure diagram illustrating an example of the schedule information holding unit 108. The schedule information holding unit 108 includes a user site ID, a scheduled wake-up time that is a time when a user of the user site specified by the user site ID is scheduled to wake up on the target date, and a time when the user is scheduled to go out on the target date. And the scheduled return time, which is the time when the user is scheduled to go home on the target date, and the scheduled sleep time, which is the time when the user is scheduled to go to sleep on the target date, are stored in association with each other.

  In addition, it may be configured such that a plurality of sets of scheduled going-out time and scheduled return home time can be registered in the scheduled information holding unit, assuming that the user goes out several times a day. In the present embodiment, it is assumed that one such set is registered in the schedule information holding unit 108 for easy understanding. However, it will be understood by those skilled in the art who have touched this specification that the technical idea according to the present embodiment can be applied even when a plurality of such sets are registered in the schedule information holding unit.

  In addition, when a plurality of users are associated with the user site (for example, a single-family house in which a multi-family home lives), the scheduled wake-up time may be the scheduled wake-up time of the earliest user, It may be the scheduled time of going out of the user who leaves the house the latest (final exit), the scheduled time of returning home may be the scheduled time of going home of the user who goes home the earliest (first visitor), It may be the scheduled bedtime of the user who goes to bed most recently (final sleeper). However, who to set each time on the basis of a plurality of users is basically arbitrary, and may be set as appropriate.

  FIG. 5 is a data structure diagram illustrating an example of the scheduled power generation amount holding unit 110. The scheduled power generation amount holding unit 110 stores the time zone on the target day and the scheduled power generation amount in the time zone in association with each other. The unit of the planned power generation amount shown in FIG. 5 is any appropriate unit.

Returning to FIG. 2, the pre-processing unit 102 includes a power schedule information acquisition unit 112, a scheduled power generation amount calculation unit 114, and a scheduled power generation amount notification unit 116.
The power schedule information acquisition unit 112 for each user site is power schedule information regarding which usage pattern of the three usage patterns (that is, at-home non-sleeping pattern, absence pattern, and sleeping pattern) is to use power. Is obtained via the network 16. The power schedule information is information indicating a schedule for the target day, and the power schedule information acquisition unit 112 acquires the power schedule information by the day before the target date. In particular, the power schedule information includes a scheduled wake-up time, a planned time to go out, a planned time to go home, and a planned time to go to bed. The power schedule information is generated at the user terminal based on the user input to the user terminal used by the user at the user site. The user terminal is, for example, a home server, a smart meter, a schedule notification dedicated terminal, a personal computer, a laptop computer, or a portable terminal. The user terminal is configured to be able to communicate with the control device 100 via the network 16. An example in the case where the user terminal is a mobile terminal will be described later with reference to FIGS. 7, 8, 9, and 10.

  The power schedule information acquisition unit 112 registers each time included in the power schedule information acquired from the user terminal in the schedule information holding unit 108 in association with the user site ID of the user site of the user who uses the user terminal. .

  The scheduled power generation amount calculation unit 114 calculates the scheduled power generation amount on the target date based on the power schedule information for the target date held in the schedule information holding unit 108. The scheduled power generation amount calculation unit 114 refers to the schedule information holding unit 108 and determines a usage pattern as a schedule of each user site in each time zone of the target date. In particular, the scheduled power generation amount calculation unit 114 uses the usage pattern of the period from the scheduled wake-up time to the scheduled going-out time as the non-sleeping pattern at home, the usage pattern of the period from the planned going-out time to the scheduled return time from the absent pattern, and the planned return time The usage pattern for the period until the scheduled bedtime is determined as a home non-sleeping pattern, and the usage pattern for other periods is determined as a sleeping pattern. In the example of the schedule information holding unit 108 illustrated in FIG. 4, the scheduled power generation amount calculation unit 114 sets the usage pattern as the schedule of the user site “A” in the time zone “22:30 to 23:00” to “non-sleeping at home”. “Pattern” is determined, and the usage pattern as a schedule of the user sites “B”, “C”, and “D” is determined as “sleeping pattern”.

  The scheduled power generation amount calculation unit 114 calculates the planned power generation amount in each time zone on the target day based on the determined usage pattern as a schedule. If the percentage of user sites planning a non-sleeping pattern at home in a certain time zone is large, the planned power generation amount in that time zone increases. In addition, the planned power generation amount in the time zone when the ratio of the user sites planning the absence pattern is large becomes small. The calculation of the planned power generation amount based on the ratio of each usage pattern may be realized using a known power generation planning technique. Further, as shown in Patent Document 1, the scheduled power generation amount calculation unit 114 may calculate the planned power generation amount on the premise that charging / discharging of the power storage device at each user site is controlled.

The scheduled power generation amount calculation unit 114 registers the scheduled power generation amount obtained by the calculation in the planned power generation amount holding unit 110.
The scheduled power generation amount notification unit 116 refers to the scheduled power generation amount holding unit 110 to generate planned power generation amount information including the planned power generation amount for each time zone on the target day, and the generated planned power generation amount information is transmitted via the network 16. To the power plant 6. The power plant 6 may create a power generation plan for the target day based on the received scheduled power generation amount information.

  Real-time processing unit 104 includes a switching information acquisition unit 118, a pattern difference determination unit 120, a power generation change determination unit 122, a planned power generation amount correction unit 124, a correction notification unit 126, and a site device control unit 128. .

  The switching information acquisition unit 118 acquires switching information indicating switching of power usage patterns at the user site as needed via the network 16 for each user site. The switching information is information indicating the switching of the usage pattern on the target day in real time. In particular, the switching information includes any one of information indicating the user's getting up, information indicating the user's going out, information indicating the user's return home, or information indicating the user's going to bed. The switching information is generated at the user terminal based on the user input to the user terminal used by the user at the user site. Examples of such user terminals include, in addition to those described above, a dedicated terminal for waking up / at home / absent / sleeping notification, an electronic key, a human sensor, and the like. These devices are configured to be able to communicate with the control device 100 via the network 16. An example in the case where the user terminal is a mobile terminal will be described later with reference to FIGS. 7, 8, 9, and 10.

なお、実際の使用パターンは切替情報が取得されると変更されるので、実際の使用パターンは、少なくとも切替情報取得部１１８によって切替情報が取得されるか否かに基づき決定されるものである。 The switching information acquisition unit 118 updates the actual usage pattern of the user site registered in the user information holding unit 106 based on the acquired switching information. In particular, the switching information acquisition unit 118 updates the actual usage pattern according to the rules shown in the following table.

Since the actual usage pattern is changed when the switching information is acquired, the actual usage pattern is determined based on at least whether the switching information is acquired by the switching information acquisition unit 118.

  The pattern difference determination unit 120 determines the difference between the actual usage pattern of each user site and the planned usage pattern at a predetermined time interval, for example, an interval of 10 minutes, on the target date. The pattern difference determination unit 120 refers to the schedule information holding unit 108 and determines a usage pattern as a current schedule of each user site. The pattern difference determination unit 120 may determine the usage pattern using the same relationship as the relationship between each time and the usage pattern used in the scheduled power generation amount calculation unit 114. The pattern difference determination unit 120 determines, for each user site, the difference between the determined usage pattern as the current schedule and the actual usage pattern currently held by the user information holding unit 106.

The pattern difference determination unit 120 calculates the following four ratios by determining the difference between the actual use pattern and the planned use pattern across a plurality of registered user sites, for example, all user sites.
(1) The ratio of user sites in which the usage pattern as scheduled and the actual usage pattern are different (hereinafter referred to as the first ratio). The first ratio is defined as (the number of user sites where the planned usage pattern differs from the actual usage pattern) / (total number of user sites). The ratio shown below is also the same.
(2) The proportion of user sites whose average usage amount of power in the planned usage pattern is smaller than the average usage amount of power in the actual usage pattern (hereinafter referred to as the second rate). Such a user site is, for example, a user site whose actual usage pattern is a non-sleeping pattern at home while the planned usage pattern is a sleeping pattern.
(3) A ratio of user sites in which the average usage amount of power in the planned usage pattern is larger than the average usage amount of power in the actual usage pattern (hereinafter referred to as a third ratio). Such a user site is, for example, a user site in which the planned usage pattern is a home non-sleeping pattern, but the actual usage pattern is an absent pattern.

  The power generation change determination unit 122 determines whether or not to change the planned power generation amount held by the planned power generation amount holding unit 110 based on the determination result in the pattern difference determination unit 120. In particular, the power generation change determination unit 122, when the first ratio, the second ratio, or the third ratio calculated by the pattern difference determination unit 120 exceeds a predetermined threshold, the scheduled power generation in the time zone ahead of the current date on the target date Determine that the amount should be changed.

The mode of changing the scheduled power generation amount includes at least the following two.
(1) When the second ratio calculated by the pattern difference determination unit 120 exceeds the first threshold value, the power generation change determination unit 122 determines that the planned power generation amount in the previous time zone should be increased. When the power generation change determination unit 122 makes such a determination, the scheduled power generation amount correction unit 124 updates the scheduled power generation amount holding unit 110 so that the planned power generation amount corresponding to the previous time zone increases.
(2) When the third ratio calculated by the pattern difference determination unit 120 exceeds the second threshold value, the power generation change determination unit 122 determines that the planned power generation amount in the previous time zone should be reduced. When the power generation change determination unit 122 makes such a determination, the scheduled power generation amount correction unit 124 updates the scheduled power generation amount holding unit 110 so that the planned power generation amount corresponding to the previous time zone decreases.

  When the scheduled power generation amount correction unit 124 corrects the planned power generation amount, the correction notification unit 126 refers to the planned power generation amount holding unit 110 and generates power generation amount correction information including the correction contents. The correction notification unit 126 transmits the generated power generation amount correction information to the power plant 6 through the network 16. The power plant 6 may perform power generation based on the corrected scheduled power generation amount.

  The site device control unit 128 is in charge of controlling various electrical devices installed at the user site in the DR aggregation service provided using the control device 100. When the scheduled power generation amount is calculated on the premise of controlling charging / discharging of the power storage device at each user site as shown in Patent Document 1, the site device control unit 128 generates appropriate command information, and the generated command Information is transmitted to the target power storage device, home server, or smart meter via the network 16. At this time, the site device control unit 128 may use an IP address registered in the user information holding unit 106.

  The site equipment control unit 128 may control charging / discharging of the power storage device at the user site based on the corrected scheduled power generation amount. For example, when the planned power generation amount increases as a result of the correction, the site device control unit 128 may perform control so that the increment is compensated by the discharge from the power storage device.

  The site device control unit 128 extracts an actual usage pattern of the user site including the electrical device to be controlled from the user information holding unit 106. The site equipment control unit 128 controls the electrical equipment to be controlled through the network 16 on the condition that the extracted actual usage pattern is the absence pattern. When the electric device to be controlled is an air conditioner or lighting, the site device control unit 128 turns on the air conditioner or lighting of the user site that is in the absence pattern when the power supply / demand tightness is reported from the power plant 6 side. If it is, control to turn it off is executed. As described above, when the user is absent, by passing the control right of the electric device to the DR aggregator, appropriate power demand control can be realized without making the user feel excessive inconvenience.

  The point processing unit 130 performs eco-point increase / decrease processing for each user site (each user) held by the user information holding unit 106. The eco point is an index indicating how much power the user of the user site is using as planned. The point processing unit 130 performs a subtraction process on the eco point of the user site determined to have a different use pattern in the pattern difference determination unit 120, and increases the eco point of the user site determined to have the same use pattern. Thereby, the eco point increases as the user uses the power as scheduled. This eco point may be exchangeable with money or goods at an appropriate exchange rate. In this case, it is possible to prompt the user to consume electric power as scheduled, and the deviation between the power generation plan and the actual situation can be suppressed.

  FIG. 6 is a schematic diagram for explaining the real-time control in the control device 100. Usage patterns as schedules at the user sites “A”, “B”, “C”, and “D” correspond to the respective times shown in FIG. A slanting line at the lower right indicates a period when the power usage pattern at the user site is a non-sleeping pattern at home, a slanting line at the lower left indicates a period when the power usage pattern at the user site is absent, and a horizontal line indicates the power at the user site. The period during which the usage pattern is a sleeping pattern is shown.

And when the ratio of the user site which shows the determination result similar to user site "B" and "C" exceeds a 1st threshold value, time slot | zone "23 by the effect | action of the electric power generation change determination part 122 and the scheduled electric power generation amount correction part 124 is shown. : 00-23: 30 "is increased.

When the user taps the send button 206, the mobile terminal generates login authentication information including the user ID input in the user ID input area 202 and the password input in the password input area 204. The portable terminal transmits the generated login authentication information to the control device 100 via the network 16. The pre-processing unit 102 performs a predetermined authentication process by collating the user ID and password included in the received login authentication information with the user ID and password registered in the user information holding unit 106. The pre-processing unit 102 transmits the authentication result to the mobile terminal via the network 16. When the authentication result is unsuccessful, the portable terminal displays a screen indicating an error on the touch panel. When the authentication result is successful, the portable terminal displays the menu screen 208 on the touch panel.

  FIG. 8 is a representative screen view of the menu screen 208. The menu screen 208 includes a tomorrow's electricity reservation specification area 210 that receives a menu specification for generating and transmitting power schedule information, a check-in specification area 212 that receives a menu specification for generating and transmitting switching information, An advertisement display area 214 for displaying advertisements.

The electric reservation reception screen 216 includes a scheduled wake-up time input area 218 for receiving an input of a scheduled wake-up time, an expected going-out time input area 220 for receiving an input of an expected going-out time, and an estimated return time input area 222 for receiving an input of an expected return time. A scheduled bedtime input area 224 for receiving an input of the scheduled bedtime, a send button 226, and an advertisement display area 214.

  The user enters the scheduled wake-up time input area 218, the scheduled going-out time input area 220, the scheduled return time input area 222, and the expected going to bed time input area 224, respectively, at the scheduled wake-up time, scheduled going-out time, and scheduled to go home.

Is generated. The portable terminal transmits the generated power schedule information to the control device 100 via the network 16. The power schedule information acquisition unit 112 acquires this power schedule information.

  When the user taps on the check-in designation area 212 on the menu screen 208, the mobile terminal displays on the touch panel a notification reception screen 228 for receiving notification of the occurrence of an event corresponding to the switching of the usage pattern at the user site. Such an event is, for example, the user getting up, going out, returning home, or going to bed.

The notification reception screen 228 includes a wake-up button 230 corresponding to the user's wake-up notification, an out-going button 232 corresponding to the user's wake-up notification, a return home button 234 corresponding to the user's wake-up notification, and the user's sleep notification. , And an advertisement display area 214. When the user taps the wake-up button 230, the mobile terminal generates switching information including information indicating the user's wake-up. The portable terminal transmits the generated switching information to the control device 100 via the network 16. The switching information acquisition unit 118 acquires this switching information. The same applies to the outing button 232, the return home button 234, and the bedtime button 236.

The operation of the control device 100 configured as above will be described.
FIG. 11 is a flowchart showing a series of processes related to the preliminary process in the control apparatus 100. The control device 100 acquires power schedule information from the users at the respective user sites (S302. The control device 100 calculates a planned power generation amount on the target day based on the acquired power schedule information (S304). 100 notifies the planned power generation amount obtained as a result of the calculation to the power plant 6 via the network 16 (S306).

  FIG. 12 is a flowchart showing a series of processing related to real-time processing in the control apparatus 100. When the switching information is acquired before the time to check the usage pattern arrives on the target date (Y in S308), the control device 100 is registered in the user information holding unit 106 based on the acquired switching information. The actual usage pattern is updated (S310). When it is time to check without acquiring such switching information (N in S308) or when the time arrives after the actual usage pattern is updated, the control device 100 determines the current time for each user site. The difference between the actual usage pattern at and the planned usage pattern is determined (S312). When the ratio of the user sites determined to be different is equal to or greater than the threshold value (Y in S314), the control device 100 corrects the scheduled power generation amount in the future time zone (S316). The control device 100 notifies the corrected power generation amount to the power plant 6 via the network 16 (S318). The control device 100 does not perform the correction process when the ratio of the user sites determined to be different is smaller than the threshold (N in S314).

  In the embodiment described above, examples of the holding unit are a hard disk and a semiconductor memory. Further, based on the description of the present specification, each unit is configured by a CPU (not shown), a module of an installed application program, a module of a system program, a semiconductor memory that temporarily stores the content of data read from the hard disk, or the like. It will be understood by those skilled in the art who have touched this specification that it can be realized.

  According to the control device 100 according to the present embodiment, in a service for creating a power generation plan based on a reservation of power usage from the user, the difference between the actual usage pattern at the user site and the planned usage pattern is monitored. be able to. If this deviation is large, the power generation plan is corrected in real time. Therefore, a service that can appropriately cope with the deviation from the power demand schedule due to the uncertainty of the user's behavior while realizing the optimization of the power generation plan based on the reservation is provided.

  For example, when there are many user sites that use more power than planned, the control device 100 can increase the scheduled power generation amount, and vice versa. Therefore, the power generation amount at the power plant 6 can be finely adjusted according to the real-time situation on the user site side. In particular, useless power generation and discharge from the storage battery can be suppressed.

  In addition, the control device 100 according to the present embodiment determines an actual usage pattern based on information obtained from the user. Here, if the user is requested to report one by one regarding what usage pattern is currently in use, there is a possibility that the burden on the user side will increase. Therefore, the control device 100 according to the present embodiment is configured to receive switching information from the user in real-time processing, update the actual usage pattern, and determine the difference between the actual usage pattern and the planned usage pattern. ing. Therefore, since the user notifies the control device 100 of the switching information regarding the switching instead of the usage pattern itself, the number of notifications can be reduced, and the burden on the user side can be reduced.

  In general, one of the important things in power generation planning is that the power demand does not exceed the power supply. When the amount of power demand exceeds the amount of power supply, an unexpected burden is generated on the distribution network 18 and the power plant 6, and there is a possibility that the stable supply of power may be hindered. Therefore, control apparatus 100 according to the present embodiment corrects to increase the planned power generation amount when the proportion of user sites that use more power than planned is large. Thereby, it can be made more certain that the amount of power demand does not exceed the amount of power supply.

  In the service provided by the control device 100 according to the present embodiment, the switching information and the power schedule information are generated and transmitted by a notification application program installed in the user's mobile terminal. Therefore, the notification work by the user can be simplified and the cost can be reduced as compared with the case where a dedicated terminal for notification is provided at the user site or the notification function is incorporated into the smart meter. As a result, the user can easily participate in the service.

  In addition, the notification application program includes the advertisement display area 214 in the notification reception screen 228. Since the notification acceptance screen 228 is a screen that the user opens many times a day due to its nature, the advertising effect of the advertisement displayed in the advertisement display area 214 can be enhanced.

  The configuration and operation of the control device 100 according to the embodiment has been described above. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to each component and combination of processes, and such modifications are within the scope of the present invention.

  In the embodiment, the case where the same mobile terminal generates the power schedule information and the switching information has been described. However, the present invention is not limited to this. For example, the power schedule information is generated and transmitted by the smart meter, while the switching information is generated by the mobile terminal. It may be generated and transmitted. Both the power schedule information and the switching information may be generated and transmitted by a user input from some terminal used by the user at the user site, or may be automatically generated and transmitted like a human sensor.

  In the embodiment, the real-time processing unit 104 may execute a notification related to the arrival of each time for the user. For example, the real-time processing unit 104 may activate an alarm of the user's mobile terminal or send an alert mail to the user's mobile terminal a few minutes before the user's scheduled going-out time. In this case, it is possible to further suppress the deviation between the reservation and the actual by prompting the user to perform the action as scheduled.

  In the embodiment, each time held by the schedule information holding unit 108 may be updated at any time. The control device 100 may be configured to be able to accept a change in each time held in the schedule information holding unit 108 from the user, whether before the target date or on the target day. When such a reservation change function is implemented, the real-time home information according to the embodiment may be positioned to complement the reservation change function.

  In the embodiment, a case has been described in which the notification application program enables an electric reservation or check-in when authentication by a user ID and a password is successful. However, the present invention is not limited to this. For example, authentication using a two-dimensional barcode such as a QR code (registered trademark) may be used.

  The inventor has the following recognition about the means for notifying the control device 100 of the switching information. A smart meter has a root segment. The A route is a route for exchanging with an electric power company outside the house, and is obtained via a communication network such as electric power or via the Web. The B route is a route governing the house and is obtained directly from the meter. The C route is a route acquired through a third party and is via the Internet. (Note that the A route is a route for receiving power information collected by the power company via the Internet, etc., and the B route is a route for connecting the HEMS directly to the meter to receive the power information, and the C route is a third party. (There is also the idea that it is a route for receiving power information via the Internet.)

  The information that flows through the A route is mainly for public applications and has high publicity and public interest. Currently, various information related to the house seems to be included in the B route via HEMS, but real-time home information is important information that is useful for optimized power generation. Dynamic information acquisition is desirable. The DR aggregator and the power plant can improve the power generation efficiency by collecting these data and performing dynamic management.

  In addition, considering the specifications of the smart meter and the capacity of the communication network, specifications for sucking up local information in 30-minute increments are currently under consideration. For packet communication via mobile phones and smartphones, smart grid communication networks It is possible to transfer freely and freely information that is not bound by.

  In the embodiment, the method for voluntarily transmitting information by the contractor mainly under the agreement between the contractor and the service provider has been described. However, the present invention is not limited to this. For example, physical information acquisition and information transmission methods in unconscious behavior in the life of the contractor may be used. In this case, a home or company may be marked using the GPS function, and a system for notifying when the mark matches the registry mark may be constructed. Thereby, two kinds of signals, mainly departure and return, can be obtained. In this regard, for example, a function of “automatic guidance” provided by Nomura Research Institute, Ltd. may be used to realize a function of seamless automatic notification.

Hereinafter, the basis of the inventor's idea about the embodiment will be described.
There are two definitions of battery. One is active, which refers to generator operation. The other is passively operating, which refers to buffered operation.

  When used as a buffer, there are many models in which the battery does not cause a chemical reaction. This is because it depends on operations that require immediate effect. The operation as a buffer is satisfied if there is some grace for electricity. Capacitors and the like do not perform chemical reactions because they retain their electric charges.

  On the other hand, in the case of operation that operates as a generator, for example, NAS (sodium-sulfur battery) often has a character that requires a chemical reaction. A large amount of power generation is required, but there is no high demand for immediate effect.

  The above may be mapped to, for example, a power supply system for mobile phones. Even if it is called a mobile phone power supply, the power supply structure model is divided into types according to the timing, frequency, and usage.

The first power source opening is equipped with a charger, which is equipped with an electrolytic capacitor (largest size as a power supply device for a mobile phone) according to the capacity of use.
Next, the power supply of the battery of the mobile phone has a buffered supply power source (medium capacitor) according to the amount of power used.
As a minimum part of the cellular phone component, a large number of microcomputers and memories exceeding several tens are mounted, and a small quartz in the microcomputer moves with a minimum power and at a high frequency. These microcomputers are supplied from a (small) tantalum capacitor installed on the side of the microcomputer instead of going to the main power supply sequentially (power supply is not in time).

  In other words, it seems that smart grids may require detailed power supply operations according to the timing, frequency, and amount of use as described above.

Furthermore, there is a similar concept / operation model in the storage world. RPO (target recovery point) and RTO (target recovery time).
FIG. 13 is an explanatory diagram for explaining the correspondence between various times at the user site and the concept of RTO / RPO. In FIG. 13, “buffer” represents an adjustment band in which the amount of power used changes. For example, a case where the “inverter” moves is equivalent. “Idling” is a state where the “buffer” state is extended, generating electricity that is not known when it is used, or burning it as primary energy, but changing it to secondary energy (electricity). Represents no period. For example, the generator engine is running, but the transmission corresponds to the neutral state.

  The RPO corresponds to a scheduled time of power fluctuation that causes a significant fluctuation in power usage when the customer wakes up, goes out, returns home, or goes to bed. The RPO may be a time index (when it occurs) when a large power usage fluctuation occurs when supplying power. The timing at which a disaster occurs corresponds to a real performance time, such as a trigger or flag that activates the actual power switch on / off, that is, a timing when the user goes home from the outside and a timing when the user goes out.

  The RTO corresponds to the time required for adaptation on the supply side with respect to fluctuations in power demand. For example, when the demand for electric power from consumers increases, it is possible to discharge from each subdivided storage battery. However, it takes time until electricity is generated in the case of chemical reaction types such as NAS and fuel cells. I need it. In addition, when supplying power, the RTO may correspond to the maximum length of time required for power supply optimization adjustment, such as turning on / off the generator or storage battery according to the power usage peak or standby power mode. .

  Further, when mapping to a mobile phone, the on / off action of the power switch by the consumer (mobile phone user) becomes the disaster timing, and the time when the full charging is finished becomes the RPO. Charging time corresponds to RTO.

  In this way, not only the reservation information by the electric power consumer is acquired, but also the timing at which the electric power use fluctuation starting from now on based on the reservation from the consumer occurs, in other words, the supply side notifies the location notification of the outing / returning home of the consumer in real time. Obtaining is very useful for delicate power supply control.

In addition, it corresponds to an RPO flag or a disaster timing trigger at least four times in 24 hours a day.
1. (First wake-up person) 1. (Last outing person) When going out or starting factory / office operation 3. (First returnee) When returning home or when the factory / office operation is stopped (Last sleeper) When sleeping, when taking a break at the factory / office

A method of notifying the power plant side and the DR aggregator will be further described.
Generally, it is desirable to use HEMS (home energy management system) as these notification means. From the display terminal of HEMS installed on the customer side, it can be sent in combination with various monitoring information that promotes other energy saving and power saving. Furthermore, when a local storage battery is installed on the customer side, the storage battery interlocking control can be performed via the HEMS, so that the system operation is efficient. However, the full-scale spread of HEMS is coming from now on, and its hardware cost has become a major impediment to the introduction of the current situation.

  In addition, there is a method of transmitting the result data from the smart meter, but at present, the smart meter has not yet reached such a specification.

  Each company may use escalation using BEMS (Building and Energy Management System), but collect and aggregate information of players in each BEMS to achieve optimization management as a whole. There is no movement yet.

  Therefore, at present, the fastest way is to use a network that is already widely spread on the consumer side, and the infrastructure that realizes them is a mobile phone such as a smartphone and a mobile phone network. As a merit of using a mobile phone, it is already recognized by each customer as social infrastructure, and there is little risk of causing confusion in handling and operability in operation. In addition, downloading the application required for notification also makes it easy to join the service immediately. With regard to application costs and download costs, it is possible to reduce or eliminate the burden on the customer side by allowing advertising media and sponsored advertising companies to participate in the service.

  Furthermore, if a mobile phone is used, it is possible to perform not only at-home notifications but also reservations themselves, and in some cases, it is a tool that can dynamically change reservations associated with schedule changes that are likely to occur. In the future, it is possible to send signals using contactless cards such as Felica (registered trademark), card-type home keys, security company cards (via BEMS), etc. It is the fastest and most reliable to use.

Explain to consumers and motivation to participate.
The actual operation of the model according to the embodiment requires a new reporting burden on the consumer side. However, in recent years when energy conservation / saving is becoming a social responsibility of humankind, there is a demand for energy conservation operation on the supply side. It is desirable for the home to contribute to them, and further, new energy benefits for consumers, such as the provision of energy-saving contribution points (or low-cost electricity charges) for action actions such as notifications. If the service design that leads to is implemented, the operation can be fully understood.

  In recent years, standardization of protocols for HEMS communication (for example, Econet lite) has been progressing. In February 2012, an agreement was reached as a domestic standardization protocol, and an approximate standard for guaranteeing interoperability among HEMS-related manufacturers was decided. The consortium as a whole seems to be proceeding with a flow of automatic monitoring and automatic control that does not place a heavy burden on end users, rather than the idea of placing additional operational burdens on consumers. Of course, it would be desirable if it could be fully automated. However, the present inventor considers that it is quite difficult to carry out dispatch electricity in accordance with the needs of consumers who move freely and freely.

  Storage RPO is ultimately determined by the end user, not the system. In other words, it is difficult to automate RPO in the storage world. The same is true for the smart grid world. In view of energy efficiency, there is also an idea that it is a proper manner for a customer to notify a supply system of a reservation or a flag that has been returned / goed out. Just as there are red and blue traffic rules, electricity is required to operate as well.

  Smart meters are basically capable of collecting information every 30 minutes at the earliest, which means that an error of approximately 30 minutes may occur between the power generation side and the customer side. For example, it is often between 18: 00 and 20: 00 that a dual working family returns home. And it is between 22:00 and the next 10:00 about sleeping. And in these five hours, the daily power demand reaches the maximum value in a general working household. If an error of about 30 minutes occurs at home or at bedtime, a supply loss of up to one hour is calculated. This is a relatively large loss margin.

  A method of minimizing the difference between the power reservation and the actual operation in the form of “reservation change acceptance” is also conceivable. However, since the changes are irregular, it will be difficult to ensure operation on the customer side. In addition, the quality of reservation changes varies from customer to customer. For example, it varies from person to person, such as 10 minutes or 1 hour. Therefore, it seems difficult to fill in the reservation information and the actual operation difference only with the reservation change function.

  Therefore, the embodiment adopts an operation of transmitting the switching information by pressing the return button of the portable terminal saying “I will use electricity as I made a reservation from now on” with the same feeling as lighting the entrance when returning. This is a more natural action, and if you make a habit, you can get information from any household every day.

  More desirable is a mechanism for changing the standby power supply to 50A or 60A by inserting or removing the key when returning home or going to work, as in the case of hotel key operation. This can be said to be an operation that requires an action to insert or remove a key from the consumer side and enforces power usage restrictions. You may change a smart meter so that it can respond to such insertion and removal of a key. Alternatively, it is possible to install a button at the entrance of the entrance. In addition, when the reservation start time comes, it is possible to forcibly reduce the transmission voltage to the standby power supply, and then allow the user to restore it by himself / herself. For example, 60A may be dropped to 10A.

  Moreover, the operation | movement which installs the human body reaction sensor like an infrared sensor in a room is also considered. However, in this case, when pets such as dogs and cats are kept, a situation may occur in which the sensor reacts even though it is unattended. In addition, when the customer's movement is small, such as when sleeping or sleeping due to illness, the sensor may not respond even though it is manned. A remote remote control method that is used when a person is at home needs improvement in these respects. In the embodiment, “yes, not” is registered based on a report from the user. Therefore, it is safer and more reliable. In addition, the security of the security company is also inferred from the fact that the “security set” has a reporting system that is performed by the user.
