Description

  The present invention relates to a technique for managing supply of electric power mainly used by a household living in a detached house.

  Conventionally, the supply source of electric power consumed in a general household has been limited to a commercial power generation device, that is, an electric power supply device provided by an electric power company.

  On the other hand, in recent years, with the price reduction of private power generation devices represented by solar power generation devices, they are spreading to general households. As a result, there is a tendency for multiple power supply sources in general households.

  In addition, with the spread of private power generation devices, a system called selling electricity that sells surplus power from ordinary households to power companies has been introduced. When using the power sale system, ordinary households purchase (purchase) insufficient power from commercial power generators if the amount of power generated by the private power generator is less than the amount of power consumed. If it exceeds, you can earn income by selling (selling) surplus power to the power company.

  In this way, when multiple power supply sources are added and the option of selling surplus power is added, it is determined how to properly use power purchase and power sale to maximize profits for general users It becomes difficult to do.

  In order to solve the above problems, a mechanism for advising a user of a general household on a method of power consumption desirable has been proposed. For example, in Patent Document 1 and Patent Document 2, the cost associated with power consumption is minimized based on data indicating the power generation amount in the solar power generation device and data indicating the power consumption amount generated by the solar power generation device. There has been proposed a mechanism for automatically generating advice information indicating a method of power consumption for conversion to a user and providing it to a user via a Web page or the like.

JP 2002-101554 A JP 2003-259551 A

  The above-mentioned diversification of power supply sources in general households will continue to expand. For example, the storage battery is becoming one of the new power supply sources due to the widespread use of the storage battery along with the price reduction of the storage battery. For example, with the spread of hybrid cars and electric cars, it is becoming possible to use storage batteries (in-vehicle storage batteries) installed in those private cars as a power supply source.

  When a storage battery was introduced as a new power supply source, it stored the power purchased at night when the power purchase price was relatively low, and stored the power shortage in the daytime in rainy weather etc. By supplementing with electric power, it is possible to reduce costs associated with electric power consumption. However, it is not easy for a general user to determine desirable storage and discharge timings.

  In addition, there is a possibility that the power supply business, which is currently conducted exclusively by one power company in one region, will be carried out by multiple power companies in the future.

  When multiple power companies set different power purchase prices and power sales prices, it is also possible to determine from which power company to purchase power and to which power company it is desirable to sell power. ,It's not easy.

  Furthermore, there are a plurality of power distribution paths used in general households, and the amount of power consumed differs for each power distribution path. Therefore, for example, when the amount of power generated by a solar power generation device cannot cover the power consumption of the entire household, the power generated by the solar power generation device is supplied to a distribution path that consumes just the right amount of power. If the power purchased from the commercial power generation device can be supplied to the other power distribution paths, more efficient power consumption can be realized, and the costs associated with power consumption can be reduced.

  However, in order to achieve efficient power consumption as described above, a distribution board for supplying power from different power supply sources to each of the plurality of distribution paths is required, and such distribution of power is required. Although it is necessary to control the board correctly at the right timing, it is not easy for a general user to do so.

  In view of the above circumstances, the present invention enables a power consumer who uses a solar power generation device and a storage battery as a power supply source in addition to a commercial power generation device to easily perform desirable power consumption that maximizes profits. It aims to provide a means.

  The distribution board 11 includes a functional component as shown in FIG. 2 in order to realize the above functions. The roles of the functional components provided in the distribution board 11 are generally as follows.

Control data receiving unit 111: Receives control data, which is data for instructing establishment and release of connection, from the home server device 16.
Transmitter 112: Data (input state data) indicating the presence or absence of power supply from the commercial power generator 12 to the home server device 16, and data (input) indicating the power supply amount and power consumption at each input terminal and each output terminal Power amount data and output power amount data).
Control unit 113: Controls establishment and release of connection in the distribution board 11 according to the control data received from the home server device 16.

  Input state data generation unit 114: has a sensor that constantly measures the voltage at the commercial power generator input terminal I1 that receives power input from the commercial power generator 12, and the voltage measured by the sensor is a predetermined value close to 0 volts. If it falls below the threshold value, power failure start notification data, which is data notifying the start of a power failure, is generated, and after the power failure start notification data is generated, the voltage measured by the sensor exceeds the predetermined threshold value close to the rated voltage In this case, power outage end notification data that is data for notifying the end of the power outage is generated. The power failure start notification data and the power failure end notification data are collectively referred to as input state data.

  Input power amount data generation unit 115: has a sensor that constantly measures the amount of power supplied from each power supply source to the distribution board 11 via each input terminal, and within a predetermined time every predetermined time Input power amount data which is data indicating a cumulative value of the power amount measured by the sensor is generated.

  Output power amount data generation unit 116: has a sensor that constantly measures the amount of power supplied from the distribution board 11 to each power consuming device via each output terminal, and within a predetermined time every predetermined time Output power amount data that is data indicating a cumulative value of the power amount measured by the sensor is generated.

  Remaining power storage data receiving unit 117: Receives power storage remaining data indicating the remaining power storage of the storage battery 13 from the storage battery 13.

  Input / output terminal group IO: A group of input terminals for receiving power from each power supply source and output terminals for supplying power to each power consuming device.

  Conductive wire group LD: A group of conductive wires for electrically connecting each of the input terminals and each of the output terminals included in the input / output terminal group IO.

  Switch group SW: A group of switches that electrically open and close the connection between the input terminals included in the input / output terminal group IO and the conductors connected to the output terminals. Each switch included in the switch group SW is controlled to be opened and closed by the control unit 113.

  By the way, in the power input / output management system 1, the number of each of the commercial power generation device 12, the storage battery 13, the solar power generation device 14, and the power distribution path 15 varies arbitrarily depending on the household. For example, in a household using four storage batteries 13, the number of storage batteries 13 connected to the distribution board 11 is four, and in a household with eight distribution paths, it is connected to the distribution board 11. The number of power distribution paths 15 is eight. Moreover, when the electric power supply from a some electric power company can be received, the number of the commercial power generation devices 12 also becomes plural.

  In addition, the number of the solar power generation devices 14 is plural, or in addition to the solar power generation devices 14, a private power generation device of another method (for example, a fuel cell cogeneration device) different from the solar power generation device is used. 11 can also be connected.

  However, in the following description, for the sake of convenience, as shown in FIG. 1, it is assumed that there are one commercial power generation device 12 and one solar power generation device 14, two storage batteries 13, and three distribution paths 15.

  FIG. 3 is a diagram schematically showing the electrical connection relationship between the input / output terminal group IO, the conducting wire group LD, and the switch group SW. In FIG. 3, the solid line indicates each conductor included in the conductor group LD, and the circles (● or ◯) indicated by the lattice points indicate the switches included in the switch group SW.

  Specifically, the input terminals and output terminals included in the input / output terminal group IO are as follows.

Commercial power generator input terminal I1: An input terminal (first input terminal) for power supplied from the commercial power generator 12 during power purchase.
Commercial power generator output terminal O1: An output terminal (first output terminal) for power supplied to the commercial power generator 12 at the time of power sale.
Storage battery output terminal O2: An output terminal (second output terminal) for power supplied to the storage battery 13 during storage.
Storage battery input terminal I2: An input terminal for power supplied from the storage battery 13 during discharge (second input terminal).
Photovoltaic power generator input terminal I3: an input terminal for power supplied from the solar power generator 14 (third input terminal).
Power distribution path output terminal O3: an output terminal (third output terminal) for supplying power to a power distribution path to which a power consuming device such as a home appliance is connected.
Photovoltaic power generator output terminal O4: This is an output terminal for supplying electric power necessary for their operation to devices included in the solar power generator 14 such as a power conditioner.

  In the following description, when there are a plurality of the same types of input terminals and output terminals, branch numbers such as “−1” and “−2” are attached to the reference numerals to distinguish them. For example, since the storage battery 13 connected to the distribution board 11 is two in this case, two of the many input terminals provided in the distribution board 11 are used as the storage battery input terminal I2. Are referred to as storage battery input terminal I2-1 and storage battery input terminal I2-2, respectively.

  For example, the circle mark (●) of the fourth lattice point from the left in the uppermost stage in FIG. 3 is a switch that opens and closes the electrical connection between the commercial power generator input terminal I1 and the distribution path output terminal O3-1. Show. By closing this switch, the power from the commercial power generator 12 connected to the commercial power generator input terminal I1 is connected to the power distribution path 15-1 connected to the power distribution path output terminal O3-1. It will be supplied to power consuming devices such as home appliances. Moreover, when this switch is opened, the power supply from the commercial power generator 12 to the power consuming device connected to the power distribution path 15-1 is stopped.

  In FIG. 3, white circles (O) among the circle marks of the grid points indicate switches that are not normally closed. For example, the white circle (◯) at the upper left lattice point in FIG. 3 is a switch that connects the commercial power generation device 12 to the commercial power generation device 12, so this switch is not normally closed. Therefore, when the devices connected to the grid points indicated by white circles are fixed, the connection may always be released without providing switches at those grid points.

  Also, a plurality of switches on the same stage (row) and grid point in the same column in FIG. 3 may be closed simultaneously. For example, when all the switches indicated by the black circles (●) in the uppermost stage are closed, the two storage batteries 13, the three power distribution paths 15 and the photovoltaic power generation device 14 (device such as a power conditioner) are connected from the commercial power generation device 12. All will be supplied with power.

  The commercial power generator 12 is managed by an electric power company, supplies power to each household, and supplies the surplus power to power consumers in other households in response to the reverse power flow of surplus power in each household. It is a device to do. It should be noted that the price of power purchased from the commercial power generator 12 is usually lower in the time zone from midnight to tomorrow than in the daytime. In addition, there are many cases where a complicated fee system is set such that the basic charge and unit price change depending on the contracted power capacity, and the unit price increases step by step when the total amount of power consumption every month increases.

  The storage battery 13 is a device that stores the power supplied from the distribution board 11 and supplies the stored power to the distribution board 11 as necessary. In the example of FIG. 1, the storage battery 13 includes two types, an in-vehicle storage battery 13-1 that is a storage battery mounted on a private car such as a hybrid car, and a stationary storage battery 13-2 that is stationary on a residential site. It is connected to the distribution board 11.

  Each storage battery 13 has a sensor that measures the amount of electric power currently stored in its own machine, generates remaining power amount data indicating the amount of electric power measured by the sensor, and from the distribution board 11 The remaining power storage data generated in response to the request is transmitted to the distribution board 11.

  The solar power generation device 14 has, as its main components, a solar panel 141 that is a panel for converting solar energy into electric energy, and a DC current generated by the solar panel 141 with an unstable voltage as a rated voltage ( And a power conditioner 142 which is a device for converting to a stable alternating current of 100 volts or 200 volts.

  The power conditioner 142 requires a power supply for its operation. In the present embodiment, it is assumed that all the electric power used for the operation of the power conditioner 142 is covered by the electric power supplied from the distribution board 11 via the solar power generation apparatus output terminal O4. Therefore, the power conditioner 142 receives power supply from the distribution board 11 while power generation by the solar panel 141 is performed.

  However, the power conditioner 142 has, for example, a built-in storage battery having a sufficient capacity, stores a part of the power generated by the solar panel 141 in the past, and has a function of performing independent operation with the stored power. In such a case, it is not necessary for the power conditioner 142 to receive power supply from the distribution board 11, and therefore, the photovoltaic power generator output terminal O 4 is not required in the distribution board 11.

  The power distribution path 15 is an electric supply path corresponding to each of the breakers arranged in the distribution board 11. Each of these power distribution paths 15 is connected to one or more power outlets provided inside and outside the house, and household appliances such as lighting fixtures, air conditioning appliances, refrigerators, and the like are connected to the power outlets. The distribution board 11 can turn on / off the power supply to each power distribution path 15 by the control according to the control data even when the breaker is in the ON state.

  The home server device 16 specifies the open / closed state of each switch of the switch group SW that brings the maximum profit to the household in the house where the distribution board 11 is arranged, and distributes the switch to the specified open / close state. It is a device that generates control data for instructing the switchboard 11 and transmits it to the distribution board 11. In this embodiment, the home server device 16 is realized by causing a general computer provided with data communication means to execute processing according to an application program. However, the home server device 16 may be configured as a dedicated device.

  The home server device 16 generates control data according to different standards during normal times (when no power failure occurs and when a planned power failure occurs) and during emergencies (when no planned power failure occurs). More specifically, the home server device 16 generates control data so as to minimize the cost associated with power consumption in the normal state (maximize the net profit when the net profit is generated by the power sale).

  On the other hand, in an emergency, the home server device 16 predicts the time until recovery from an unplanned power outage according to the duration of the unplanned power outage. Therefore, the purpose is to maintain the power supply to the power distribution path 15 to which the high-importance type home appliances are connected for as long as possible, and if necessary, only the low-importance type home appliances Control data is generated so as to stop power supply to the connected power distribution path 15.

  The home server device 16 includes a functional component as shown in FIG. 4 in order to realize the above functions. The roles of the functional components included in the home server device 16 are generally as follows.

  The following various data are stored in the storage unit 163 of the home server device 16 in order to enable the processing of the power consumption prediction unit 164, the power generation amount prediction unit 165, the determination unit 166, and the control data generation unit 167 described above.

  The above is the main data stored in the storage unit 163. The household attribute data and the device identification data are changed by the user when, for example, a child starts living alone or purchases a new home appliance. Those change histories are also recorded in the storage unit 163. When using past data before the change of the data (for example, the same household output power amount data), the household before the change is used as necessary.

  The public server device 17 responds to the inquiry data from the home server device 16 to the home server device 16 with the device attribute data, power rate data, predicted weather data, confirmed weather data, other household output power amount data, and It is a server apparatus which transmits other household input electric energy data. In this embodiment, the public server device 17 is realized by causing a general computer having data communication means to execute processing according to an application program. However, the public server device 17 may be configured as a dedicated device.

  The public server device 17 includes a functional configuration unit as shown in FIG. 5 in order to realize the above functions. The roles of the functional components included in the public server device 17 are generally as follows.

  Receiving unit 171: Receives various inquiry data, output power amount data, and input power amount data transmitted from home server device 16 of each household, and predicts weather data and confirmation transmitted from weather data providing server 18 Receive weather data.

  The meteorological data providing server 18 stores the above-described predicted meteorological data and confirmed meteorological data (for each region and each time zone) in an updated state at any time, and the latest data according to the transmission request data from the public server device 17. Are transmitted to the public server device 17.

  The above is the configuration of the power input / output management system 1.

  In the power input / output management system 1 having the above-described configuration, the distribution board 11 is generally controlled as follows. In the following example, it is assumed that the nighttime power purchase fee is cheaper than the daytime power purchase fee, and the power sale fee is higher than the daytime power purchase fee.

  First, in normal times, control for the purpose of cost minimization is performed.

  During normal daytime, the power supply source supplied to the power consuming device is preferentially selected in the order of (1) storage battery 13, (2) commercial power generator 12, and (3) solar power generator 14. . Because the electric power stored in the storage battery 13 is purchased at night, the cost is generally the lowest even in consideration of the conversion efficiency, and the selling price of the electric power generated by the solar power generation device 14 is This is because the price is higher than the purchase price when purchasing power from the commercial power generator 12.

  That is, during normal daytime, the control unit 113 of the distribution board 11 first sets the storage battery input terminal I2 within the range of the output capacity of the storage battery 13 according to the control data received from the home server device 16 (commercial use). Then, the commercial power input terminal I1 is connected to the output terminal (other than the commercial power output terminal O1). The storage battery input terminal I2 is connected to the commercial power supply output terminal O1.

  However, if there is a planned power outage in the daytime, the power supply from the commercial power input terminal I1 cannot be obtained, so the power supplied from the storage battery input terminal I2 cannot cover all power consumption. The solar power generator input terminal I3 is also connected to some output terminals to compensate for the shortage.

  Next, at nighttime during normal times, the power supply source supplied to the power consuming device is preferentially selected in the order of (1) the commercial power generator 12 and (2) the storage battery 13. This is because the electricity purchase price is cheap at night. In addition, since the electric power generation by the solar power generation device 14 is not performed at night, it is excluded from options as a power supply source.

  That is, at normal nighttime, the control unit 113 of the distribution board 11 sets the commercial power input terminal I1 to all output terminals other than the commercial power output terminal O1 in accordance with the control data received from the home server device 16. Connecting. As a result, the electric power purchased from the commercial power generator 12 is stored in the storage battery 13 until the storage capacity is reached. Therefore, discharge from the storage battery 13 is not normally performed.

  However, when there is a planned power outage at night, power supply from the commercial power input terminal I1 cannot be obtained, so the storage battery input terminal I2 is connected to the power distribution path output terminal O3 and discharged from the storage battery 13. Electricity is used to cover the power consumed by home appliances.

  The control data for instructing the control of the distribution board 11 at the normal time is based on the predicted power consumption data and the predicted power generation data generated based on the predicted values such as the temperature and the amount of sunlight from the next day onward. Generated at night. However, the control data generated on the previous day is corrected as needed based on the input power amount data and output power amount data of the day determined by actual measurement and the predicted weather data updated as needed.

  On the other hand, in the event of an emergency, that is, an unplanned power outage, control is performed for the purpose of maintaining the operation of a highly important power consuming device such as a medical device or a refrigerator for a long period of time.

  In the daytime during an emergency, the power supply source supplied to the power consuming device is preferentially selected in the order of (1) the solar power generation device 14 and (2) the storage battery 13. This is because it is necessary to maintain the remaining amount of power stored in the storage battery 13 as much as possible in preparation for prolonged power outage.

  That is, when a sufficient amount of power generation cannot be obtained by the solar power generation device 14 in the daytime in an emergency, the solar power generation device input terminal I3 is connected to the storage battery output terminal O2 and the distribution path output terminal O3, The storage battery input terminal I2 is connected only to the solar power generation apparatus output terminal O4 that requires external power supply. On the other hand, when a sufficient amount of power generation cannot be obtained by the solar power generation device 14 due to, for example, cloudy weather during emergency daytime, the storage battery input terminal I2 is connected to part or all of the power distribution path output terminal O3. Make up for the shortfall.

  In an emergency night, the power source supplied to the power consuming device is limited to the storage battery 13 and there are no other options.

  Therefore, at night in an emergency, the storage battery input terminal I2 is connected to all of the power distribution path output terminals O3 and the solar power generation apparatus output terminal O4.

  Control of power consumption in the first few hours (for example, 3 hours) immediately after the occurrence of an unplanned power outage is as described above. It is desirable to maintain the power supply to the highly important power consumption device as much as possible by stopping the power supply to the device.

  Therefore, according to the control data, for example, when the unplanned power outage continues for more than 3 hours, the distribution board 11 is attached to the connected power consuming device among the plurality of power distribution path output terminals O3. The power supply to the power distribution path output terminal O3 whose maximum value of the sex index (any one of the natural numbers “1” to “5”) is 2 or less is stopped. In addition, the home server device 16 lists, for example, home appliances connected to the power distribution path 15 whose power supply is not stopped and whose importance index is 2 or less, for e-mail addresses registered in advance by the user. Up and send an email advising you to switch off those appliances.

  Further, for example, when the unplanned power outage continues over 12 hours, the distribution board 11 is attached to the connected power consuming device among the plurality of power distribution path output terminals O3 according to the control data. The power supply to the output terminal O3 for the distribution path whose maximum value of the sex index is 4 or less, for example, is stopped, and the same advice mail as described above is transmitted.

  As described above, according to the power input / output management system 1, the user can minimize the cost associated with the power consumption in the normal time without any trouble, and the power consumption that is highly important in the emergency time. The operation of the device can be maintained as long as possible.

(Modification)
The above-described embodiments can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below.

  In the above-described embodiment, a configuration is adopted in which the home server device 16 and the public server device 17 cooperate to provide control data to the distribution board 11, but the public server device 17 is used as the home server device 16. A configuration in which the home server device 16 is not used may be employed. In that case, the distribution board 11 directly performs data communication with the public server device 17 without using the home server device 16, and receives and uses control data generated in the public server device 17. . When such a configuration is adopted, for example, when data communication between the distribution board 11 and the public server device 17 is interrupted in an emergency, there is a disadvantage that control of the distribution board 11 is not automated. Each household is convenient because it is not necessary to prepare the home server device 16.

  The function sharing method between the home server device 16 and the public server device 17 is not limited to the above-described embodiment. For example, a configuration in which the public server device 17 includes all functions of the home server device 16 may be employed. In that case, when the data distribution board 11 can perform data communication with the public server device 17, the distribution board 11 directly performs data communication with the public server device 17 and can receive control data from the public server device 17. it can. The home server device 16 can be used for backup in an emergency by synchronizing the necessary data periodically with the public server device 17.

  In the above-described embodiment, the home server device 16 is configured to acquire the predicted weather data and the confirmed weather data via the public server device 17, but the home server device 16 uses the public server device 17. The structure which acquires those data directly from the weather data provision server 18 without going through may be employ | adopted.

In the above-described embodiment, a configuration is adopted in which control data is generated for the purpose of minimizing costs during normal times. For example, control data is generated for the purpose of minimizing CO 2 emissions. Other indicators may be used as a reference for generating control data.

  Various data such as input power amount data (indicating the amount of power purchased or generated) and output power amount data (indicating the amount of power sold or consumed) stored in the home server device 16 or public server device 17. May be added to the power input / output management system 1 to provide various information to the user.

  First, such information provision is realized, for example, by adding a Web server function for distributing Web pages to the home server device 16 or the public server device 17.
