[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6951010 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the building of Patent Document 1, the charger in the parking area is supplied with power from the residential area. Therefore, in the building of Patent Document 1, the charger for charging residents' vehicles needs to be connected to the residential area where the residents live. For example, if a parking area of ​​a resident who does not need a parking space is made available for use by another resident, work to change the charger connection is required. Similarly, if the parking area is converted into a store, office, shared space, etc. for use by people other than the residents of the corresponding residential area, the configuration of the power equipment also needs to be changed.

[0005] The present disclosure aims to provide a power management system and a power management method that can easily change the correspondence between multiple users and multiple zones in an apartment building. [Means for solving the problem]

The power meters are provided in a plurality of power equipments in a one-to-one correspondence with a plurality of sections in an apartment building, and measure the power consumption of the plurality of sections. The storage unit stores a plurality of users of the apartment building in association with each of the plurality of sections. The power consumption calculation unit calculates the power consumption of each of the plurality of users based on the power consumption of the plurality of sections measured by each of the plurality of power meters.

[0007] A power management method according to one aspect of the present disclosure includes a measuring step, a storing step, and a power consumption calculation step. In the measuring step, the power consumption of a plurality of sections is measured using a plurality of power meters provided in each of a plurality of power facilities in an apartment building, each of which corresponds one-to-one with a plurality of sections. In the storing step, a plurality of users of the apartment building are stored in association with each of the plurality of sections. In the power consumption calculation step, the power consumption of each of the plurality of users is calculated based on the power consumption of the plurality of sections measured by each of the plurality of power meters. The storing step and the power consumption calculation step are executed by one or more processors. [Effects of the Invention]

[Figure 2] 2A and 2B are schematic diagrams of the second and first floors of an apartment building in which the power management system of the same embodiment is used. [Figure 3]FIG. 3 is a schematic diagram of an apartment building in which the above-mentioned power management system is used. [Figure 4] FIG. 4 is a flowchart showing the operation of the power management system. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, power management systems according to embodiments will be described in detail with reference to the drawings. However, the drawings described in the following embodiments are schematic diagrams, and the ratios of the sizes and thicknesses of the components do not necessarily reflect the actual dimensional ratios.

[0011] (Embodiment) (1) Overview The power management system 1 (see FIG. 1) is a system that manages, for example, power equipment 4 (see FIG. 3) that supplies power to a plurality of sections in an apartment building.

[0012] Here, "power equipment 4" refers to power distribution equipment that is fixed to a building. The power distribution equipment includes a distribution board 41 (see FIG. 3), wiring devices, and outlets. The wiring equipment also includes a power conditioner 43, solar panels 44, and a charger 45 for electric vehicles (see FIG. 3). The wiring equipment may also include a storage battery.

[0013] The power management system 1 calculates the amount of power consumed by power facilities in each of a plurality of sections in an apartment building, and calculates the amount of electricity consumed by each of a plurality of users in the apartment building.

[0014] (2) Building composition The power management system 1 is installed in an apartment building 2 (see Figures 2A to 3). As shown in Figures 2A, 2B, and 3, the apartment building 2 has a plurality of sections 3. The apartment building 2 is, for example, a low-rise, two-story apartment building. A low-rise apartment building refers to an apartment building that is a low-rise building. A low-rise building is a house that is a low-rise structure that is lower than a mid-rise building or a high-rise building, and generally refers to a three-story, two-story, or one-story (single-story) building.

[0015] The apartment building 2 has four sections 3 on each of the first and second floors. Fig. 2A is a schematic plan view of the second floor of the apartment building 2, and Fig. 2B is a schematic plan view of the first floor of the apartment building 2. Fig. 3 is a schematic diagram showing the relationship between one first section 31 and one second section 32 of the apartment building 2 and two pieces of power equipment 4 corresponding to each of the first section 31 and the second section 32.

[0016] Each of the multiple compartments 3 is used exclusively by, for example, one user from among multiple users. For example, if compartment 3 is a residential space, the user is the resident of compartment 3. Also, for example, if compartment 3 is a parking space, the user is the owner or user of the vehicle parked in compartment 3. Note that one or more of the multiple compartments 3 may be, for example, a space managed by the owner or manager of the apartment complex 2 and shared by multiple users. Also, one or more of the multiple compartments 3 may be, for example, an office used by a specified number of people under the management of a user, or a store used by an unspecified number of people.

[0017] The multiple sections 3 include multiple (four in FIG. 2A ) first sections 31 and multiple (four in FIG. 2B ) second sections 32. Each of the multiple first sections 31 is, for example, a living space. The multiple first sections 31 have, for example, different users. Note that one user may use two or more first sections 31. Each of the multiple first sections 31 is, for example, located on the second floor or higher (the second floor in FIGS. 2A and 3 ) of the apartment building 2. Each of the multiple first sections 31 has an entrance / exit 311 that connects to the outside of the apartment building 2. The entrance / exit 311 is, for example, a front door. Therefore, a user of each of the multiple first sections 31 can use one first section 31 as a residence. Note that in the apartment building 2 shown in FIGS. 2A and 2B , each of the multiple first sections 31 includes a portion installed on the first floor, and the entrance / exit 311 is located on the first floor.

[0018] Each of the multiple second compartments 32 is, for example, a non-residential space. Each of the multiple second compartments 32 is, for example, an inner garage. Note that the use of the multiple second compartments 32 is not limited to inner garages, and may be, for example, a warehouse, a store, an office, a meeting hall, etc. The user of each of the multiple second compartments 32 is, for example, one of the users of the multiple first compartments 31. For example, the user of the second compartment 32 is the same as the user of the first compartment 31 located directly above the second compartment 32. This makes it easier for the user of the second compartment 32 to move from the first compartment 31 to the second compartment 32. Furthermore, the user of the second compartment 32 may be the user of a first compartment 31 other than the one directly above the second compartment 32, or may be a person who is not a user of the first compartment 31.

[0019] Each of the multiple second sections 32 is located, for example, on the first floor, which is the lowest floor, of the apartment building 2. This allows users of each of the multiple second sections 32 to easily use the second section 32 for various purposes, such as a garage or a store. Each of the multiple second sections 32 has a first entrance 321 and a second entrance 322 as entrances and exits connecting to the outside of the apartment building 2. The first entrance 321 is an entrance for users of the second section 32 to enter and exit. For example, the first entrance 321 is an entrance through which people can pass but not vehicles, and is provided with a door. The second entrance 322 is an entrance used for the intended use of the second section 32. For example, if the second section 32 is used as a garage, the second entrance 322 is an entrance and exit for automobiles and motorcycles. Furthermore, for example, if the second section 32 is used as a store, the second entrance 322 is an entrance and exit for customers of the store. The second entrance 322 is provided with, for example, a shutter. This allows users of each of the multiple second compartments 32 to use, for example, the first entrance / exit 321 as an entrance / exit for entering and exiting the second compartment 32, and to use the second entrance / exit 322 depending on the purpose of using the second compartment 32.

[0020] (3) System configuration (3.1) Power equipment The power management system 1 is installed in an apartment building 2. As shown in FIG. 3, the apartment building 2 has a plurality of power facilities 4 that correspond one-to-one to a plurality of blocks 3.

[0021] As shown in Fig. 1, the power management system 1 includes a plurality of (three in Fig. 1) power meters 42, a memory unit 11, and a power consumption calculation unit 12. The plurality of power meters 42 are included in a plurality of power facilities 4. Note that the number of power meters 42 is equal to the number of power facilities 4 and equal to the number of sections 3, but Fig. 1 shows only three power meters 42, and the remaining power meters 42 are not shown. The memory unit 11 and the power consumption calculation unit 12 are installed in, for example, an apartment building 2.

[0022] Each of the plurality of power facilities 4 includes a distribution board 41, a power meter 42, a power conditioner 43, and a solar panel 44.

[0023] The distribution board 41 is provided in the section 3 among the multiple sections 3 that corresponds to the power equipment 4. The distribution board 41 distributes the power received from the power grid 5 via the power meter 42 to the outlets, lighting fixtures, etc. in the section 3. The distribution board 41 also distributes the power received from the power conditioner 43 to the outlets, lighting fixtures, etc. in the section 3, and if there is any surplus power, outputs a reverse power flow to the power grid 5.

[0024] The power meter 42 measures the amount of power consumed by the corresponding section 3. The power meter 42 is connected between the distribution board 41 of the corresponding section 3 and the power grid 5. The power meter 42 includes a receiving power meter 42A and a transmitting power meter 42B. The receiving power meter 42A measures the amount of power of forward flow power flowing from the power grid 5 to the distribution board 41. The transmitting power meter 42B measures the amount of power of reverse flow power flowing from the distribution board 41 to the power grid 5. The receiving power meter 42A and the transmitting power meter 42B are capable of communicating with the power consumption calculation unit 12. The receiving power meter 42A and the transmitting power meter 42B output the measured amount of power to the power consumption calculation unit 12. The receiving power meter 42A and the transmitting power meter 42B are compatible with, for example, ECHONET (registered trademark) Lite, and transmit a signal indicating the measured amount of power to the power consumption calculation unit 12. For example, when the power receiving wattmeter 42A and the power transmitting wattmeter 42B receive an inquiry about the amount of power consumption from the power consumption calculation unit 12, they transmit a signal indicating the measured amount of power to the power consumption calculation unit 12. Furthermore, the power receiving wattmeter 42A and the power transmitting wattmeter 42B may transmit a signal indicating the measured amount of power to the power consumption calculation unit 12, for example, periodically.

[0025] The power conditioner 43 is provided in one of the multiple sections 3 in a section 3 corresponding to the power equipment 4. The power conditioner 43 is connected to a solar panel 44 and a distribution board 41 included in the power equipment 4. The power conditioner 43 is interconnected with the power grid 5, and converts the DC power output by the solar panel 44 into AC power that has the same voltage, frequency, and phase as the AC power received from the power grid 5.

[0026] The multiple solar panels 44 are installed, for example, on the roof of an apartment building 2. The apartment building 2 is provided with, for example, the same number of solar panels 44 as the number of sections 3. The multiple solar panels 44 correspond one-to-one to the multiple sections 3. The solar panels 44 are so-called solar cells that generate electricity using light, and are connected to the power conditioner 43 of the corresponding section 3 via the connection box 46 of the corresponding section 3. In other words, the solar panels 44 correspond to power generation equipment.

[0027] The charger 45 is included in the power facility 4 provided in the second section 32. The charger 45 charges the electric vehicle 6 using power received from the solar panel 44 or the power grid 5. The charger 45 also converts the power received from the electric vehicle 6 into AC power that has the same voltage, frequency, and phase as the AC power received from the power grid 5.

[0028] (3.2) Storage section The storage unit 11 stores a plurality of users of the apartment building 2 in association with each of the plurality of sections 3. The storage unit 11 is, for example, a computer having a processor. The storage unit 11 may also be a storage medium that can be read by a computer including the power consumption calculation unit 12.

[0029] The memory unit 11 stores, for example, a table that associates information that identifies each of the multiple sections 3, such as a room number, with information that identifies the user of each of the multiple sections 3, such as the name of the representative.

[0030] (3.3) Power consumption calculation section The power consumption calculation unit 12 calculates the amount of power consumption of each of the plurality of users based on the amount of power consumption measured by each of the plurality of power meters 42.

[0031] The power consumption calculation unit 12 acquires the amount of power consumption from each of the multiple power meters 42. More specifically, the power consumption calculation unit 12 acquires the amount of received power from the power receiving power meter 42A for each of the multiple sections 3. The power consumption calculation unit 12 also acquires the amount of transmitted power from the power transmitting power meter 42B for each of the multiple sections 3.

[0032] The power consumption calculation unit 12 acquires from the storage unit 11 the users of the apartment building 2 corresponding to each of the multiple sections 3. The power consumption calculation unit 12 calculates the amount of power consumed for each of the multiple users of the apartment building 2. More specifically, when one user corresponds to one section 3, the power consumption calculation unit 12 determines the amount of power received by the section 3 corresponding to the user as the amount of power received by the user. When one user corresponds to one section 3, the power consumption calculation unit 12 determines the amount of power transmitted by the section 3 corresponding to the user as the amount of power transmitted by the user. On the other hand, when one user corresponds to two or more sections 3, the power consumption calculation unit 12 determines the amount of power received by the user as the amount of power transmitted by the two or more sections 3 corresponding to the user. When one user corresponds to two or more sections 3, the power consumption calculation unit 12 determines the amount of power transmitted by the two or more sections 3 corresponding to the user as the amount of power received by the user. When one user corresponds to two or more sections 3, the power consumption calculation unit 12 determines the amount of power transmitted by the two or more sections 3 corresponding to the user as the amount of power transmitted by the user.

[0033] The power consumption calculation unit 12 is, for example, a computer having a processor. More specifically, the power consumption calculation unit 12 is configured by, for example, a computer system having a CPU (Central Processing Unit) and a memory. The computer system realizes the functions of the power consumption calculation unit 12 by causing the CPU to execute a program stored in the memory. The program may be pre-recorded in the memory of the computer system, may be provided by being recorded on a recording medium such as a memory card, or may be provided via a telecommunications line such as the Internet.

[0034] (4) Operation FIG. 4 is a flowchart showing the operation of the power management system 1 according to the embodiment.

[0035] Each of the multiple power meters 42 measures the power consumption of the section 3 corresponding to the power meter 42 (step S1). More specifically, each of the multiple power receiving power meters 42A measures the amount of power received by the section 3 corresponding to the power receiving power meter 42A. Also, each of the multiple power transmitting power meters 42B measures the amount of power transmitted by the section 3 corresponding to the power transmitting power meter 42B. The power consumption calculation unit 12 acquires the amount of power consumed from each of the multiple power meters 42. More specifically, the power consumption calculation unit 12 acquires the amount of received power from the power receiving power meter 42A for each of the multiple sections 3. Also, the power consumption calculation unit 12 acquires the amount of transmitted power from the power transmitting power meter 42B for each of the multiple sections 3. Table 1 below is an example of the power consumption of the apartment building 2.

[0036] [Table 1]

[0037] The memory unit 11 stores a plurality of users of the apartment building 2 in association with each of the plurality of sections 3 (step S2). Table 2 below shows an example of users of the apartment building 2. The power consumption calculation unit 12 acquires from the memory unit 11 the users of the apartment building 2 corresponding to each of the plurality of sections 3.

[0038] [Table 2]

[0039] Here, the section number is a number that identifies each of the multiple sections 3. Specifically, each of section numbers 101 to 104 corresponds to the second section 32 on the first floor of the apartment building 2. Furthermore, each of section numbers 201 to 204 corresponds to the first section 31 on the second floor of the apartment building 2. That is, the first digit of the section number corresponds to the floor number of the apartment building 2 on which the section 3 is located. Furthermore, two sections with the same third digit of the section number are located directly above the other. That is, for example, the first section 31 with section number 203 is located directly above the second section 32 with section number 103.

[0040] The power consumption calculation unit 12 calculates the amount of power consumption for each of the multiple users of the apartment building 2 (step S3). More specifically, for one or more sections 3 used by a single user, the power consumption calculation unit 12 determines the sum of one or more amounts of received power for the user as the amount of power received by the user. Furthermore, for one or more sections 3 used by a single user, the power consumption calculation unit 12 determines the sum of one or more amounts of transmitted power for the user as the amount of power transmitted by the user. Therefore, for example, for user "tenant C," the power received by the second section 32 with section number 103 and the first section 31 with section number 203 are summed up, and the respective amounts of transmitted power are summed up. Similarly, for user "tenant D," the power received by the second section 32 with section number 104 and the first section 31 with section number 204 are summed up, and the respective amounts of transmitted power are summed up. For users "tenant A," "tenant B," and "owner," the power received and transmitted amounts for the corresponding sections 3 are calculated as the power received and transmitted amounts for the users.

[0041] [Table 3]

[0042] This makes it easy to settle accounts between the user and the management company, for example, if the entire apartment complex 2 enters into a contract with an electric power company and the management company pays the usage fees and receives the electricity sales fee, even if one user uses multiple plots 3.

[0043] Furthermore, in the power management system 1, even if the users of some of the multiple sections 3 are changed, no construction work to interconnect or disconnect the power equipment 4 is required. In the power management system 1, the power equipment 4 of each of the multiple second sections 32 is not supplied with power from any of the multiple power equipment 4 included in the multiple first sections 31. Therefore, in the apartment building 2, it is possible to change the users of each of the multiple second sections 32 independently of changing the users of each of the multiple first sections 31. For example, even if a change in the user of the second section 32 with section number 101 is not synchronized with a change in the user of the first section 31 with section number 201 located directly above the second section 32 with section number 101, no construction work to interconnect or disconnect the power equipment 4 is required. Therefore, for example, a user of the apartment building 2 can easily give up ownership or usage rights of the second section 32 while continuing to use the first section 31, or to add ownership or usage rights to the second section 32. Therefore, in the apartment building 2, it is possible to easily set and change the correspondence between a plurality of sections 3 and a plurality of users.

[0044] (5) Effects The power management system 1 according to the embodiment includes a plurality of power meters 42, a storage unit 11, and a power consumption calculation unit 12. The plurality of power meters 42 are provided in each of a plurality of pieces of power equipment 4 that correspond one-to-one to a plurality of sections 3 in an apartment building 2, and calculate the amount of power consumed by the plurality of sections 3. The storage unit 11 stores a plurality of users of the apartment building 2 in association with each of the plurality of sections 3. The power consumption calculation unit 12 calculates the amount of power consumed by each of the plurality of users based on the amount of power consumed measured by each of the plurality of power meters 42.

[0045] Moreover, the power management method according to the embodiment includes a measuring step S1, a storing step S2, and a power consumption calculation step S3. In the measuring step S1, the power consumption of the multiple sections 3 is measured by multiple power meters 42 provided in each of multiple power equipment 4 that correspond one-to-one to the multiple sections 3 in the apartment building 2. In the storing step S2, the power consumption of each of the multiple users is calculated based on the power consumption of the multiple sections 3 measured by each of the multiple power meters 42. The storing step S2 and the power consumption calculation step S3 are executed by one or more processors.

[0046] This makes it possible to manage the amount of power consumed by each user, regardless of whether each of the multiple users uses one section 3 or multiple sections 3 in the apartment building 2. Furthermore, because the multiple wattmeters 42 correspond one-to-one to the multiple sections 3, even if there is a change in users of some of the multiple sections 3 in the apartment building 2, there is no need to perform construction work to interconnect or disconnect the power equipment 4 between the multiple sections 3. Therefore, it becomes possible to easily set and change the correspondence between the multiple sections 3 and the multiple users in the apartment building 2.

[0047] Furthermore, in the power management system 1 according to the embodiment, the multiple sections 3 include two or more first sections 31 and two or more second sections 32. Each of the multiple first sections 31 has an entrance / exit 311 that connects to the outside of the apartment building 2. Each of the multiple second sections 32 has a first entrance / exit 321 and a second entrance / exit 322 that connect to the outside of the apartment building 2. This allows one or more of the multiple users to use the first section 31 and the second section 32 for different purposes.

[0048] Furthermore, in the power management system 1 according to the embodiment, the apartment building 2 is a low-rise apartment building. The multiple second sections 32 are located on the lowest floor of the apartment building 2. This makes it easy to use the multiple second sections 32 for various purposes.

[0049] Furthermore, in the power management system 1 according to the embodiment, the plurality of second compartments 32 include inner garages. As a result, the second compartments 32, which are inner garages, are likely to face the road, making them easier for users to use, and a user who owns a vehicle can use both the first compartment 31 and the second compartment 32, improving convenience.

[0050] Furthermore, in the power management system 1 according to the embodiment, the plurality of first sections 31 include living spaces. This allows a user of the first section 31, which is a living space, to also use the second section 32 as needed.

[0051] Furthermore, in the power management system 1 according to the embodiment, at least one of the multiple power facilities 4 includes a power generation facility 44. Of the multiple power meters 42, the power meter 42 provided in the power facility 4 that includes the power generation facility 44 includes a power receiving power meter 42A and a power transmitting power meter 42B. This makes it possible for the power management system 1 to also manage the power that is generated by the power generation facility 44 and sold to the power grid 5.

[0052] Furthermore, in the power management system 1 according to the embodiment, the power generation facility 44 includes a solar panel. This allows the power management system 1 to also manage the power generated by the solar panel and sold to the power grid 5.

[0053] (Variation) (1) In the power management system 1 according to the embodiment, when the second section 32 has a charger 45, the electric vehicle 6 may be used as a storage battery for supplying power to the second section 32.

[0054] (2) In the power management system 1 according to the embodiment, each of the power meters 42 may convert the amount of power consumption into an electricity charge and output the electricity charge, and the power consumption calculation unit 12 may calculate the electricity charge for each user.

[0055] (3) In the power management system 1 according to the embodiment, each of the plurality of first sections 31 is not limited to being occupied by one user among the plurality of users, but may be occupied by a group including two or more users among the plurality of users. Similarly, each of the plurality of second sections 32 may be used by a group including two or more users. In this case, the storage unit 11 may store information identifying the group instead of the user associated with the section 3. The information identifying the group may be, for example, the name of the group, the name of the group representative, etc. In other words, the storage unit 11 may store a table that associates users or groups with each of the plurality of sections 3.

[0056] (Aspect) A power management system (1) according to a first aspect includes a plurality of power meters (42), a storage unit (11), and a power consumption calculation unit (12). The plurality of power meters (42) are provided in each of a plurality of power facilities (4) that correspond one-to-one to a plurality of sections in an apartment building (2), and measure the amount of power consumed in the plurality of sections (3). The storage unit (11) stores a plurality of users of the apartment building (2) in association with each of the plurality of sections (3). The power consumption calculation unit (12) calculates the amount of power consumed by each of the plurality of users based on the amount of power consumed in the plurality of sections (3) measured by each of the plurality of power meters (42).

[0057] The power management system (1) according to the above aspect makes it possible to manage the amount of power consumed by each of the multiple users, regardless of whether each user uses one section (3) or multiple sections (3) in the apartment building (2). Furthermore, because the multiple wattmeters (42) correspond one-to-one with the multiple sections (3), even if the users of some of the multiple sections (3) in the apartment building (2) change, no work is required to interconnect or disconnect the power equipment (4) between the multiple sections (3). Therefore, it becomes possible to easily set and change the correspondence between the multiple sections (3) and the multiple users in the apartment building (2).

[0058] In the power management system (1) according to the second aspect, in the first aspect, the plurality of sections (3) include two or more first sections (31) and two or more second sections (32). Each of the plurality of first sections (31) has an entrance / exit (311) that connects to the outside of the apartment building (2). Each of the plurality of second sections (32) has a first entrance / exit (321) and a second entrance / exit (322) that connect to the outside of the apartment building (2).

[0059] According to the power management system (1) of the above aspect, one or more of the multiple users can use the first section (31) and the second section (32) for different purposes.

[0060] In the power management system (1) according to the third aspect, the apartment building (2) is a low-rise apartment building in the second aspect, and the plurality of second sections (32) are arranged on the lowest floor of the apartment building (2).

[0061] According to the power management system (1) of the above aspect, it becomes easy to use the second sections (32) for various purposes.

[0062] In the power management system (1) according to a fourth aspect, in the second or third aspect, the plurality of second compartments (32) include an inner garage.
