Abstract

A restriction information acquisition unit (542) acquires, from a server, restriction information including a restriction interval during which power outputted from the power conditioner of a power generation facility is restricted. A suppressed power generation amount acquisition unit (543) acquires, from the power conditioner, a suppressed power generation amount obtained by subtracting the amount of power outputted by the power conditioner from the amount of power generated by a power generation module. A power use control unit (544) controls in a manner such that power consumption by a device increases during the restriction period, with the acquired suppressed power generation amount as the upper limit thereof. When doing so, if a device priority order has been set, the power use control unit (544) selects a target device according to the priority order, and controls in a manner such that the power consumption of the selected device increases.

Description

Management device and management system

The present invention relates to a management apparatus and a management system that can effectively use power in a limited period in which power output from power generation facilities is limited.

In recent years, home systems (as an example, HEMS: Home Energy Management System) in which power generation facilities typified by solar power generation have been introduced have become widespread. In this home system, the power of a general household can be appropriately managed.

In addition, not only ordinary homes but also regional systems (for example, CEMS: Community Energy Management System) that manage electric power in the entire region such as buildings, factories, stores, and schools are becoming widespread.

As a prior art of such a regional system, for example, Patent Document 1 discloses an invention of an energy management system that can absorb and reduce surplus power generated by power generation in a region by heat storage operation.

JP 2012-55078 A

By the way, the supply and demand balance of the commercial power system may be disrupted due to the reverse power flow in which power is supplied from the customer to whom the power generation facility is introduced to the commercial power system (commercial power supply). For example, on a sunny holiday, the demand decreases significantly, and the supply increases as the power generation amount increases.

Therefore, in order to maintain the supply and demand balance of the commercial power system, the development of a system is in progress for an electric power company to specify the time for the consumer in advance to instruct suppression (restriction) of reverse power flow. For example, in 2014, Japan's Agency for Natural Resources and Energy announced an output control rule for photovoltaic power generation. This output control rule adjusts the power generation amount of the power generation facility to suppress the sale of power to the commercial power system.

As an example of a specific operation, when an electric power company plans a restriction period (time zone) in which output from power generation facilities should be restricted, it creates restriction information including restriction contents (upper limit of output) in the restriction period. . The electric power company provides the created restriction information to the power generation facility via the network. Then, the power generation facility suppresses the power generation amount so as not to exceed the output upper limit when the limit period comes in accordance with the provided limit information.

However, the invention described in Patent Document 1 does not reduce the reverse power flow according to the instruction for suppressing the reverse power flow as described above. That is, since no consideration is given to the provision of the restriction information, the power cannot be suppressed even if the restriction period comes as it is. As a result, the invention described in Patent Document 1 cannot effectively use power in the limited period.

The present invention has been made to solve the above-described problems, and a management apparatus and a management system capable of effectively utilizing power in a limited period in which power output from power generation equipment is limited The purpose is to provide.

In order to achieve the above object, the management device according to the present invention provides:
A management device that manages equipment that consumes power supplied from a commercial power source or power output from a photovoltaic inverter,
Receiving means for receiving restriction information including a restriction period in which power output from the photovoltaic inverter is restricted and a restriction value in the restriction period;
Based on the restriction information received by the receiving means, control means for controlling the device so that power consumption of the device increases during the restriction period;
Is provided.

According to the present invention, power can be effectively utilized by appropriately increasing power consumption in a limited period in which power output from the power generation facility is limited.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals. Hereinafter, as a specific example, a case where the present invention is applied to a home system will be described. However, as described later, the present invention can be similarly applied to a building system. That is, the embodiment described below is for explanation, and does not limit the scope of the present invention. Therefore, those skilled in the art can employ embodiments in which each or all of these elements are replaced with equivalent ones, and these embodiments are also included in the scope of the present invention.

(Embodiment 1)
FIG. 1 is a block diagram showing an example of the overall configuration of a home system 1 according to Embodiment 1 of the present invention. As shown in the figure, the home system 1 includes a power generation facility 10 that generates power, a device 20 that consumes power in the residence H, a breaker 30 that shuts off power supplied to the residence H, and a residence H. It includes a power measuring device 40 that measures power consumed or generated, a management device 50 that controls the entire home system 1, and a terminal device 60 that is used by a user.

The thick line in FIG. 1 indicates the power line PL. That is, power is connected to the power generation facility 10, the device 20, and the breaker 30 so that power can be supplied or output via the power line PL. And near them, current transformer CT for measuring the electric power which flows into electric power line PL is arranged.

Further, the dotted line in FIG. 1 indicates the communication line CL. That is, the power generation facility 10, the device 20, the power measuring device 40, the management device 50, and the terminal device 60 are connected to the home network N1 through the communication line CL. The communication line CL (home network N1) is, for example, a wired LAN (Local Area Network) or a wireless LAN.

In addition, the home system 1 can communicate with the server 70 arranged outside the residence H via the outside network N2. The server 70 stores restriction information 71 including a restriction period during which power output from the power generation facility 10 should be restricted. This restriction information 71 is appropriately read from the management device 50, for example. Details of the restriction information 71 will be described later.

As an example, the power generation facility 10 is a solar power generation system including a power generation module 11 and a power conditioner 12.

The power generation module 11 includes, for example, a solar panel and generates power by receiving sunlight. This power generation module 11 will be described below in the case where the rated capacity (maximum generated power) is 5 kW as an example.

The power conditioner 12 is composed of, for example, a photovoltaic inverter (Photo Voltec inverter), and converts the power (direct current) generated by the power generation module 11 into alternating current and outputs the alternating current. For example, when the restriction information 71 is supplied via the management device 50, the power conditioner 12 suppresses the output in the restriction period. Note that the power conditioner 12 may read the restriction information 71 directly from the server 70 without using the management device 50.

In the restriction information 71, for example, as shown in FIG. 2A, an output upper limit (up to what percentage of the rated capacity of the power generation module 11 can be output) in each time (time zone) is defined. In this example, the output from 0 o'clock to 9 o'clock and from 15 o'clock to 24 o'clock is defined as 100% (that is, no limit). Further, the output from 9 o'clock to 11 o'clock and from 13 o'clock to 15 o'clock is defined as 40%. The output from 11:00 to 13:00 is defined as 0%. In other words, the time period when the output is smaller than 100% is the limit period, and the output upper limit in the limit period is the limit value. The restriction information 71 illustrated in FIG. 2A is an example and can be changed as appropriate. For example, instead of specifying the output upper limit by the ratio (%), the output upper limit may be specified by the power value (n [kW]).

When such restriction information 71 is supplied, the power conditioner 12 generates power with the line Lp as the upper limit even if the power generation module 11 generates power as indicated by the line La as shown in FIG. 2B, for example. Output. In other words, during the limited period (9:00 to 15:00), less power than the power generated by the power generation module 11 is output. In particular, from 11:00 to 13:00, the output power is set to 0 (no power is output).

In addition, when self-consumption (electricity purchase) has occurred in such a limited period, the power conditioner 12 has the power until the self-consumption (when the power generation amount of the power generation module 11 is sufficient). Can be output. That is, as shown in Figure 2C, the backward flow P _R at the connection point C, a power P _G outputted from the power generation facility 10, and a power P _L that is consumed by device 20, determined by Equation 1 below .

P _R = P _G −P _L (Formula 1)

The power conditioner 12, when the power P _R> 0, and outputs the electric power is suppressed to the upper limit value (line Lp). On the other hand, if power P _R ≦ 0, the power can be increased and output until power P _R = 0 converges.

This will be specifically described with reference to FIG. 3, the transition of the power P _L that is consumed by device 20, is indicated by a chain line. Also shows the power P _G outputted from the power generation facility 10 by a thick solid line. That is, in the limited period (9:00 to 15), during a time period the power P _L is below the upper limit (line Lp), the power conditioner 12 outputs the power P _G to 2kW to be the upper limit. Thereafter, when the power P _L exceeds the upper limit value, the power conditioner 12 increases the power value to the same power value as the power P _L and outputs the power P _G. Incidentally, the power P _L exceeds the power generation amount (line La), the power conditioner 12 outputs the power P _G having the same power value and the power generation amount.

Moreover, the power conditioner 12 subtracts the power generation amount generated by the power generation module 11 in such a limited period, and the reduced power generation amount obtained by subtracting the power amount output by the power conditioner 12 (for example, the power consumption of the entire residence H). It is obtained and transmitted to the management device 50. For example, the power conditioner 12 obtains the suppressed power generation amount Y1 at time T1, and obtains the suppressed power generation amount Y2 at time T2, and transmits it to the management device 50. The power conditioner 12 may periodically obtain the suppressed power generation amount and transmit it to the management device 50. In addition, in response to a request from the management device 50, the power conditioner 12 obtains the suppressed power generation amount and manages the management device 50. 50 may be transmitted.

Such a suppressed power generation amount indicates the amount of power from the current power consumption (that is, the output of the power conditioner 12) to the original power generation amount. That is, power consumption can be increased by the amount of suppressed power generation.

Further, the above method of obtaining the suppressed power generation amount is an example, and the suppressed power generation amount may be obtained by another method. As an example, the power conditioner 12 estimates the power generation amount of the power generation module 11 and subtracts the power amount output from the power conditioner 12 (for example, the power consumption of the entire residence H) from the estimated power generation amount, thereby suppressing the power generation amount. You may ask for. In this case, the power conditioner 12 estimates the power generation amount of the power generation module 11 from the past power generation amount and weather information.

Specifically, the power conditioner 12 stores the maximum power generation amount (in units of 30 minutes) of the power generation module 11 in the past two weeks, and estimates the power generation amount of the power generation module 11 using the value. The merit of using the values for the past two weeks is that at least one sunny day is included in the two weeks (exists with a very high probability), and the effective maximum power generation amount is Will always be remembered. In one week, it may happen that there is no clear day during the rainy season. Furthermore, since the season does not change significantly in the past two weeks, the power generation amount estimated using the maximum power generation amount is appropriate. Moreover, if the weather information is partly cloudy, the power conditioner 12 sets the power generation amount to the power generation amount when it is cloudy only during that time period. The power conditioner 12 may estimate the power generation amount of the power generation module 11 from either the past power generation amount or weather information. Further, instead of the power conditioner 12, the management device 50 described later may estimate the power generation amount of the power generation module 11.

Returning to FIG. 1, the device 20 is a power consuming device that consumes power in the residence H. As an example, a storage battery, an electric vehicle, an electric water heater, an air conditioner, a refrigerator, a washing machine, an automatic cleaner, and a vacuum cleaner , Ventilation fan, television, lighting, and floor heater. In addition, although FIG. 1 shows a case where two devices 20 are arranged in the house H, this is for ease of explanation, and the number of devices 20 can be changed as appropriate according to the actual situation. .

Breaker 30 appropriately cuts off the supply of power from commercial power source PS to power line PL in residence H. For example, the breaker 30 performs electrical connection between the commercial power source PS and the power line PL when the power consumed in the house H (power supplied from the commercial power source PS) exceeds a predetermined capacity. Cut off. The capacity of the breaker 30 is determined, for example, when a user makes a contract with an electric power company. The breaker 30 may be an earth leakage breaker.

The power measurement device 40 includes, for example, a power detection unit 41 and a communication unit 42. The power detection unit 41 detects the amount of power flowing through the power line PL using the above-described current transformer CT. For example, the communication unit 42 transmits information on the amount of power detected by the power detection unit 41 (that is, power information) to the management device 50.

As an example, the management device 50 is a HEMS (Home Energy Management System) controller that can control the device 20 in the residence H. For example, the management device 50 communicates with the power measurement device 40 via the communication line CL, and collects power information about the amount of power measured by the power measurement device 40. In addition to this, the management device 50 acquires the suppressed power generation amount from the power generation facility 10 (power conditioner 12) via the communication line CL. In addition, the management device 50 acquires the restriction information 71 from the server 70 via the outside network N2.

An example of the configuration of the management device 50 will be described below with reference to FIG. FIG. 4 is a block diagram illustrating an example of the configuration of the management device 50. As illustrated, the management device 50 includes an in-home communication unit 51, an out-of-home communication unit 52, a data storage unit 53, and a control unit 54.

The in-home communication unit 51 is a communication unit for connecting to the in-home network N1 through the communication line CL, for example, and under the control of the control unit 54, the power generation facility 10, the device 20, the power measuring device 40, and the terminal device 60. Communicate with. For example, the in-home communication unit 51 receives power amount information (power information) transmitted from the power measurement device 40. Further, the in-home communication unit 51 receives the suppressed power generation amount sent from the power generation facility 10 (power conditioner 12). In addition, the in-home communication unit 51 transmits screen data (for example, a control status display screen described later) generated by the control unit 54 (display control unit 546 described later) to the terminal device 60.

The out-of-home communication unit 52 is, for example, a communication adapter for connecting to an external outside network N2, and performs communication with the external server 70 under the control of the control unit 54. For example, the out-of-home communication unit 52 receives the above-described restriction information 71 sent from the server 70.

The data storage unit 53 is configured by, for example, a non-volatile semiconductor memory, and stores the power information received from the power measurement device 40, the suppressed power amount received from the power conditioner 12, and the limit information 71 received from the server 70. To do. In addition, as will be described later, the data storage unit 53 indicates past power generation amount information (power generation amount transition), past power consumption information (power consumption amount transition), weather information, and a user's action schedule. Various information such as schedule information is stored.

The control unit 54 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (none of which are shown), and controls the entire management device 50. Functionally, the control unit 54 includes a power information collection unit 541, a restriction information acquisition unit 542, a suppressed power generation amount acquisition unit 543, a power utilization control unit 544, an operation reception unit 545, and a display control unit 546. Is provided. These functions are realized by the CPU using the RAM as a work memory and appropriately executing, for example, various programs stored in the ROM (for example, a power utilization control processing program described later).

The power information collection unit 541 collects power information including the amount of power measured by the power measurement device 40. That is, the power information collection unit 541 collects the power consumption amount consumed by the device 20.

The restriction information acquisition unit 542 acquires restriction information 71 stored in the server 70. That is, the restriction information acquisition unit 542 acquires the restriction information 71 as illustrated in FIG.

The suppressed power generation amount acquisition unit 543 acquires the suppressed power amount calculated by the power conditioner 12. For example, the suppressed power generation amount acquisition unit 543 acquires the suppressed power amounts Y1 and Y2 as illustrated in FIG. That is, the suppressed power generation amount acquisition unit 543 acquires the suppressed power generation amount obtained by subtracting the total power consumption in the house from the power generation amount of the power generation module 11. Note that, as described above, the power generation amount may be an actual measurement value obtained from the power generation module 11 or an estimation value estimated by the power conditioner 12.

The power utilization control unit 544 controls the device 20 so that the power consumption of the device 20 increases during the limited period. For example, the power utilization control unit 544 performs control so that the power consumption amount of the device 20 increases with the suppressed power generation amount acquired by the suppressed power generation amount acquisition unit 543 as an upper limit. In more detail, the power utilization control unit 544 commands the control of the control target device 20 through the in-home communication unit 51. Specifically, the power utilization control unit 544 instructs the electric vehicle to charge or instructs the electric water heater to boil in order to effectively use the suppressed power generation amount.

The operation accepting unit 545 accepts the operation data in accordance with an operation of a user who uses the terminal device 60 (for example, an operation for setting the priority order of the device 20 as will be described later).

The display control unit 546 generates screen data to be supplied to the terminal device 60. Specifically, the display control unit 546 generates screen data constituting the control status display screen P1 as shown in FIG. 5A. As an example, the control status display screen P1 of FIG. 5A is a screen that displays the state of the device 20 controlled by the power utilization control unit 544 in the control period.

In addition, the display control unit 546 generates a control status display screen P1 on which the message screen M1 is superimposed as shown in FIG. 5B, for example, at the start of the control period. Further, for example, at the end of the control period, the display control unit 546 generates the control status display screen P1 on which the message screen M2 is superimposed as shown in FIG. 5C.

Returning to FIG. 1, the terminal device 60 is a portable terminal such as a tablet terminal or a smartphone, and is used by the user. An example of the configuration of the terminal device 60 will be described below with reference to the block diagram of FIG. As illustrated, the terminal device 60 includes a communication unit 61, a display unit 62, an input unit 63, a data storage unit 64, and a control unit 65.

The communication unit 61 is, for example, a communication unit (for example, a wireless LAN unit) for connecting to the home network N1 through the communication line CL, and communicates with the management device 50 under the control of the control unit 65.

The display unit 62 includes a liquid crystal panel, and displays various screens under the control of the control unit 65. Specifically, the display unit 62 displays the control status display screen P1 described above based on the screen data sent from the management device 50.

The input unit 63 includes a touch panel, a touch pad, and the like, and performs a process of receiving an operation input from the user. For example, when a touch panel is employed as the input unit 63, a transparent flat plate capacitive sensor that detects a change in capacitance is mounted on the liquid crystal display. When this capacitive sensor detects contact (press) on the touch surface (for the user, the display screen of the liquid crystal display) with the user's fingertip or a dedicated pen, the position information (coordinate data) is controlled. Is output to the unit 65.

The data storage unit 64 is composed of, for example, a nonvolatile semiconductor memory. The data storage unit 64 temporarily stores the screen data generated by the management device 50 and received through the communication unit 61 (for example, the screen data of the control status display screen P1 described above). In addition, the data storage unit 64 stores a program executed by the control unit 65.

The control unit 65 includes a CPU, a ROM, and a RAM (all not shown) and controls the terminal device 60 as a whole. The control unit 65 functionally includes a screen display processing unit 651 and an input detection unit 652. This function is realized by the CPU appropriately executing various programs stored in the ROM or the data storage unit 64 using the RAM as a work memory.

The screen display processing unit 651 displays a screen based on the screen data transmitted from the management apparatus 50 (for example, the above-described control status display screen P1) on the display unit 62 through the communication unit 61.

The input detection unit 652 generates operation data and transmits the operation data to the management device 50 through the communication unit 61, for example, when an operation from the user on the screen is received from the input unit 63. Specifically, the input detection unit 652 receives an operation for the user to set a priority order for the device 20 to be controlled during the limited period.

Hereinafter, the operation of the management device 50 (control unit 54) according to the first embodiment of the present invention will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of the power utilization control process executed by the control unit 54. This power utilization control process is repeatedly executed periodically, for example.

First, the control unit 54 acquires power information (step S101). That is, the power information collection unit 541 collects power information including the amount of power measured by the power measurement device 40. That is, the power information collection unit 541 collects the power consumption amount consumed by the device 20.

The control unit 54 acquires the restriction information 71 (step S102). That is, the restriction information acquisition unit 542 acquires the restriction information 71 stored in the server 70. That is, the restriction information acquisition unit 542 acquires the restriction information 71 as illustrated in FIG.

The control unit 54 determines whether or not it is during the limited period (step S103). For example, the control unit 54 compares the current time with the restriction information 71 as shown in FIG. 2A to determine whether or not the present time is in the restriction period. When the control unit 54 determines that it is not in the limit period (step S103; No), the power utilization control process is once ended.

On the other hand, when determining that it is during the limited period (step S103; Yes), the control unit 54 determines whether or not power purchase has occurred (step S104). When determining that power purchase has occurred (step S104; Yes), the control unit 54 once ends the power utilization control process. That is, since power purchase has occurred and power generation has not been performed to the extent that it is suppressed, the control unit 54 does not perform control to increase the power consumption of the device 20 as will be described later.

On the other hand, when it is determined that there is no power purchase (step S104; No), the control unit 54 acquires a suppressed power generation amount (step S105). That is, the suppressed power generation amount acquisition unit 543 acquires the suppressed power amount calculated by the power conditioner 12. For example, the suppressed power generation amount acquisition unit 543 acquires the suppressed power amounts Y1 and Y2 as illustrated in FIG.

The control part 54 performs control to the apparatus 20 according to the acquired suppression power generation amount (step S106). That is, the power utilization control unit 544 controls the device 20 so that the power consumption of the device 20 increases. For example, the power utilization control unit 544 performs control so that the power consumption amount of the device 20 increases with the suppressed power generation amount acquired in step S105 as an upper limit. Specifically, the power utilization control unit 544 instructs the electric vehicle to charge or instructs the electric water heater to boil in order to effectively use the suppressed power generation amount. Note that when the power generation amount output from the power conditioner 12 is smaller than a limit value determined from the output upper limit of the limit information 71, the control unit 54 does not control the device 20. That is, since it is more beneficial to sell power than to perform control to increase the power consumption of the device 20, control to the device 20 is not performed. Further, in this case, since the output from the power conditioner 12 is the same as not being suppressed, control for increasing the power consumption of the device 20 is not performed.

By such a power utilization control process, it is possible to effectively utilize power by appropriately increasing power consumption in a limited period in which power output from the power generation facility 10 (power conditioner 12) is limited.

(Embodiment 2)
In the first embodiment, the case where the device 20 is simply controlled in the limited period has been described. However, the device 20 may be appropriately controlled in consideration of the user's intention. Hereinafter, Embodiment 2 of the present invention will be described. Also in the second embodiment, the overall configuration is the same as in FIG.

FIG. 8 is a block diagram showing an example of the configuration of the management device 50 according to the second embodiment of the present invention. As illustrated, the management device 50 includes an in-home communication unit 51, an out-of-home communication unit 52, a data storage unit 53, and a control unit 54. The configurations of the in-home communication unit 51, the out-of-home communication unit 52, and the data storage unit 53 are the same as those in the first embodiment described above. As a difference, the data storage unit 53 stores priority order information 531 as shown in FIG.

In the priority order information 531, the priority order of the device 20 to be controlled, the condition, and the control content are associated with each other in the limited period. This priority order information 531 is an example, and can be changed as appropriate by the control unit 54 (priority order setting unit 551), as will be described later.

Returning to FIG. 8, the control unit 54 functionally includes a power information collection unit 541, a limit information acquisition unit 542, a suppressed power generation amount acquisition unit 543, a priority order setting unit 551, and a control target selection unit 552. A power utilization control unit 544, an operation reception unit 545, and a display control unit 546. That is, in the second embodiment, the priority order setting unit 551 and the control target selection unit 552 are added to the configuration of the control unit 54 in the first embodiment.

The priority order setting unit 551 sets the priority order of the devices 20 to be controlled, for example, in accordance with a user operation. In other words, the priority order setting unit 551 changes the priority order of the devices 20 in the priority order information 531 described above.

The control target selection unit 551 selects the device 20 to be controlled in the limited period according to the priority order information 531 changed by the priority order setting unit 551. For example, the control target selection unit 551 selects the devices 20 that satisfy the conditions in order from the device 20 with the highest priority in order to use the suppressed power generation amount.

Hereinafter, the operation of the management device 50 (control unit 54) according to the second embodiment of the present invention will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of the control target selection process executed by the control unit 54. This control target selection process is executed, for example, before step S106 of the power utilization control process shown in FIG. 7 described above.

First, the control unit 54 (control target selection unit 552) sets the suppressed power generation amount acquired by the suppressed power generation amount acquisition unit 543 to the remaining suppressed power generation amount, and sets the initial value 1 to the variable N representing the priority order. (Step S201).

The control unit 54 determines whether or not there is a device 20 with priority N (step S202). If the control unit 54 determines that there is no device 20 having the priority order N (step S202; No), the control unit 54 proceeds to step S208 described later.

On the other hand, when it is determined that there is a device 20 with priority N (step S202; Yes), the control unit 54 calculates the consumable amount of the device 20 (step S203). For example, if the device 20 is a power storage device such as a rechargeable battery or an electric vehicle, the control unit 54 determines the consumable amount (more specifically, the chargeable amount from the remaining time until the limit period ends and the remaining capacity of the power storage device. ). If the device 20 is a heat storage device such as an electric water heater, the control unit 54 calculates a consumable amount (more specifically, a heat storage amount) from the remaining time until the limit period ends and the remaining capacity of the heat storage device. calculate. In addition, if the device 20 is a home appliance, the control unit 54 calculates a consumable amount from the remaining time until the limit period ends and the power consumption of the home appliance.

The control unit 54 determines whether or not the remaining suppressed power generation amount is larger than the consumable amount (step S204). When determining that the remaining suppressed power generation amount is larger than the consumable amount (step S204; Yes), the control unit 54 subtracts the usable amount from the remaining suppressed power generation amount (step S205).

On the other hand, when it is determined that the remaining suppressed power generation amount is not larger than the consumable amount (step S204; No), the control unit 54 sets the remaining suppressed power generation amount to zero (step S206).

The control unit 54 adds the device 20 having the priority order N to the control target (step S207).

The control unit 54 determines whether or not the remaining suppressed power generation amount is greater than zero (step S208). When determining that the remaining suppressed power generation amount is not greater than zero (zero) (step S208; No), the control unit 54 ends the control target selection process.

On the other hand, when it is determined that the remaining suppressed power generation amount is greater than zero (step S208; Yes), the control unit 54 adds 1 to the variable N (step S209).

The control unit 54 determines whether or not the variable N is maximum (step S210). When determining that the variable N is not the maximum (step S210; No), the control unit 54 returns the process to the above-described step S202.

On the other hand, when it is determined that the variable N is the maximum (step S210; Yes), the control unit 54 ends the control target selection process.

By such a control target selection process, the device 20 can be appropriately selected in accordance with the priority order determined by the user. Similarly to the above, the power can be effectively utilized by appropriately increasing the power consumption in the limited period.

In addition to selecting the target device 20 according to the priority order, the device 20 is controlled according to the control content determined according to the operation setting of the device 20 and the type of the device 20 collected before the start of the limit period. May be.

For example, in the case of an air conditioner as an example, when the set temperature is set to “28 degrees” before the start of the restriction period and the controller 54 is operating, the control unit 54 sets the set temperature of “28 degrees” to the data storage unit 53. Remember it. Then, when utilizing the suppressed power generation amount in the limited period, even if the power consumption with the increased cooling operation can be consumed until the set temperature is “24 degrees”, the control unit 54 stores the stored “28 degrees”. In consideration, for example, the cooling operation is controlled to “26 degrees”.

In this case, the electric power can be effectively utilized by appropriately increasing the electric power consumption in accordance with the intention of the user.

For example, when the user is expected to increase the power consumption of the device 20, such as when there is a visitor's schedule during the restriction period, the power consumption prediction unit 564 predicts the power consumption considering the schedule.

Hereinafter, the operation of the management apparatus 50 (control unit 54) according to the third embodiment of the present invention will be described with reference to FIGS. FIG. 12 is a flowchart illustrating an example of the power utilization control process executed by the control unit 54. On the other hand, FIG. 13 is a flowchart showing a power generation amount prediction process called as a subroutine, and FIG. 14 is a flowchart showing a power consumption amount prediction process called as a subroutine.

In the power utilization control process of FIG. 12, the process up to step S105 is the same as that of FIG. 7, and thus the description thereof will be omitted and the process will be described from step S111.

The control unit 54 executes a power generation amount prediction process (step S111). Details of the power generation amount prediction process are shown in FIG.

The control unit 54 acquires the transition of the past power generation amount (step S301). That is, the control unit 54 obtains the transition of the power generation amount from the past power generation amount information stored in the data storage unit 53.

That is, the weather information acquisition unit 561 acquires weather information (weather forecast information) from an external weather information server (not shown). As described above, the weather information includes the expected amount of solar radiation.

The control unit 54 predicts a change in the power generation amount during the limited period based on the past power generation transition and weather information (step S303). That is, based on the transition of the past power generation amount acquired in step S301 and the weather information (expected solar radiation amount) acquired in step S302, the transition of the power generation amount in the limited period is predicted.

(Embodiment 4)
In the first to third embodiments described above, the processing during the restriction period has been mainly described. However, the device 20 may be appropriately controlled even when the restriction period ends. Embodiment 4 of the present invention will be described below. Also in the fourth embodiment, the overall configuration is the same as in FIG.

FIG. 15 is a block diagram showing an example of the configuration of the management device 50 according to the fourth embodiment of the present invention. As illustrated, the management device 50 includes an in-home communication unit 51, an out-of-home communication unit 52, a data storage unit 53, and a control unit 54. The configurations of the in-home communication unit 51, the out-of-home communication unit 52, and the data storage unit 53 are the same as those in the first embodiment described above. As a difference, the data storage unit 53 stores activation condition information 532 as shown in FIG. 16A and release condition information 533 as shown in FIG. 16B.

In the activation condition information 532 shown in FIG. 16A, conditions for activating control that utilizes the suppressed power generation amount during the restriction period are defined. In addition, in the cancellation condition information 533 illustrated in FIG. 16B, a condition for canceling the control that uses the suppressed power generation amount is predetermined. The cancellation condition information 533 also includes a condition that the limited period has ended (cancelled). The activation condition information 532 and the release condition information 533 are examples, and can be changed as appropriate according to the user's operation.

A margin is provided in the activation condition information 532 and the release condition information 533. This is because of a hysteresis (resistance to fluctuations), or when it is necessary to keep the upper and lower limits. is there.

Returning to FIG. 15, the control unit 54 functionally includes a power information collection unit 541, a restriction information acquisition unit 542, a suppressed power generation amount acquisition unit 543, a utilization control activation determination unit 571, and a utilization control release determination. Unit 572, power utilization control unit 544, operation reception unit 545, and display control unit 546. That is, in the fourth embodiment, a utilization control activation determination unit 571 and a utilization control release determination unit 572 are added to the configuration of the control unit 54 in the first embodiment.

The utilization control activation determination unit 571 determines whether to activate the control that utilizes the suppressed power generation amount according to the activation condition information 532 described above. For example, the utilization control activation determination unit 571 may suppress the power purchase when the power purchase does not occur in consideration of the margin or the amount of suppressed power generation exists in consideration of the margin. It is determined that control utilizing the power generation amount should be activated.

The utilization control cancellation determination unit 572 determines whether to cancel the control that utilizes the suppressed power generation amount according to the above-described cancellation condition information 533. For example, the utilization control cancellation determination unit 572 indicates that power purchase has occurred in consideration of the margin, that the amount of controlled power generation does not exist in consideration of the margin, and that the limit period has ended (cancelled). When the above conditions are met, it is determined that the control utilizing the suppressed power generation amount should be released.

Hereinafter, the operation of the management device 50 (control unit 54) according to the fourth embodiment of the present invention will be described with reference to FIG. FIG. 17 is a flowchart illustrating an example of the power utilization control process executed by the control unit 54. In the power utilization control process of FIG. 17, the process up to step S102 is the same as that of FIG.

The control unit 54 determines whether or not the limited period has arrived (step S121). For example, the control unit 54 compares the current time with the restriction information 71 as shown in FIG. 2A to determine whether or not the restriction period has arrived. When the control unit 54 determines that the limit period has not arrived (step S121; No), the power utilization control process is once ended.

On the other hand, when it is determined that the limit period has arrived (step S121; Yes), the control unit 54 determines whether or not power purchase has occurred (step S104). When determining that power purchase has occurred (step S104; Yes), the control unit 54 once ends the power utilization control process.

On the other hand, when it is determined that there is no power purchase (step S104; No), the control unit 54 acquires a suppressed power generation amount (step S105).

The control unit 54 determines whether or not the activation condition is met (step S122). That is, the utilization control activation determination unit 571 determines whether to activate the control that utilizes the suppressed power generation amount according to the activation condition information 532 described above. For example, the utilization control activation determination unit 571 may suppress the power purchase when the power purchase does not occur in consideration of the margin or the amount of suppressed power generation exists in consideration of the margin. It is determined that control utilizing the power generation amount should be activated. When determining that the activation condition is not met (step S122; No), the control unit 54 returns the process to the above-described step S104.

On the other hand, when it is determined that the activation condition is met (step S122; Yes), the control unit 54 performs control of the device 20 according to the acquired suppressed power generation amount (step S106). Note that the control unit 54 stores the control content before executing control on the device 20 in the data storage unit 53.

The control unit 54 determines whether or not the control period has ended (step S123). When determining that the limited period has not ended (step S123; No), the control unit 54 returns the process to step S104 described above.

On the other hand, when it is determined that the limited period has ended (step S123; Yes), the control unit 54 determines whether or not the release condition is met (step S124). That is, the utilization control cancellation determination unit 572 determines whether to cancel the control that utilizes the suppressed power generation amount according to the cancellation condition information 533 described above. For example, the utilization control cancellation determination unit 572 cancels the control to utilize the suppressed power generation amount when the user does not perform manual operation on the controlled device 20 during the restriction period. Determine that it should be done. When determining that the release condition is not met (step S124; No), the control unit 54 ends the power utilization control process. That is, the process ends while maintaining the current control.

On the other hand, when it is determined that the release condition is met (step S124; Yes), the control unit 54 returns the controlled device 20 to the original control content (step S125).

By such power utilization control processing, when the user manually controls the target device 20 during the limited period, the user's operation can be respected by not returning the control. Further, if the release condition is met, the control can be returned to the original state, and the electric power can be effectively utilized without causing unnecessary power purchase.

(Embodiment 5)
In the first to fourth embodiments described above, the processing during the restriction period and the processing at the end of the restriction period have been mainly described. However, the device 20 may be appropriately controlled before the restriction period starts. Hereinafter, Embodiment 5 of the present invention will be described. Also in the fifth embodiment, the overall configuration is the same as in FIG.

FIG. 18 is a block diagram showing an example of the configuration of the management device 50 according to the fifth embodiment of the present invention. As illustrated, the management device 50 includes an in-home communication unit 51, an out-of-home communication unit 52, a data storage unit 53, and a control unit 54. The configurations of the in-home communication unit 51, the out-of-home communication unit 52, and the data storage unit 53 are the same as those in the first embodiment described above. As a difference, the data storage unit 53 stores advance control information 534 as shown in FIG.

The pre-control information 534 defines devices to be controlled in advance and control details before the start of the limit period. The prior control information 534 is an example, and can be changed as appropriate according to a user operation.

Returning to FIG. 18, the control unit 54 functionally includes a power information collection unit 541, a restriction information acquisition unit 542, a prior control unit 581, a suppressed power generation amount acquisition unit 543, and a power utilization control unit 544. The operation receiving unit 545 and the display control unit 546 are provided. That is, in the fifth embodiment, the prior control unit 581 is added to the configuration of the control unit 54 in the first embodiment.

The pre-control unit 581 performs pre-control on the target device 20 in accordance with the pre-control information 534 described above. For example, the pre-control unit 581 partially stops boiling at night on the previous day for the electric water heater. Then, after the control period is reached, the electric water heater is restarted. That is, prior control is executed in order to secure power that can be consumed in the control period. In addition to this, when there is a reservation that the air conditioner is turned on before the control period, the advance control unit 581 delays (suspends) the reservation. Then, after the control period is reached, the reservation is made valid and the operation of the air conditioner is controlled to be ON. This is because the air conditioner consumes a large amount of electricity at the start of operation, so that it appropriately consumes electricity during the control period.

(Embodiment 6)
In the first to fifth embodiments, the single home system 1 has been described. However, a plurality of home systems 1 (devices 20 in each house) may be appropriately controlled. Hereinafter, Embodiment 6 of the present invention will be described. In the sixth embodiment, a region management system 100 (CEMS: Community Energy Management System) will be described as an example.

FIG. 20 is a block diagram showing an example of the overall configuration of the area management system 100 according to the sixth embodiment of the present invention.

As shown in FIG. 20, the regional management system 100 includes an overall management device 80, a server 70, a management device 50 (

management devices

50a, 50b, 50c,...), And a power conditioner 12 (power conditioner 12a). , 12b, 12c, ...). Although omitted in FIG. 20, the configuration of each house is the same as that of the home system 1 described above.

The overall management device 80 includes, for example, a CEMS controller that controls the entire regional system 100. The overall management device 80 is, for example, authorized by an electric power company, and can update the restriction information for the power conditioner 12 in each home, as will be described later. An example of the configuration of the overall management apparatus 80 will be described below with reference to the block diagram of FIG. As illustrated, the overall management apparatus 80 includes a communication unit 81, a data storage unit 82, and a control unit 83.

The control unit 83 includes a CPU, a ROM, and a RAM (all not shown) and controls the overall management apparatus 80. Functionally, the control unit 83 includes a restriction information acquisition unit 831, a power generation facility information collection unit 832, an overall suppressed power generation amount calculation unit 833, an allocation target selection unit 834, and a restriction information update unit 835. This function is realized by the CPU appropriately executing various programs stored in the ROM or the data storage unit 82 using the RAM as a work memory.

The restriction information acquisition unit 831 acquires the restriction information 71 described above from the server 70.

The power generation facility information collection unit 832 collects information (power generation facility information) related to the power generation facility 10 from the management device 50.

The total suppression power generation amount calculation unit 833 calculates the total suppression power generation amount whose output should be limited in the overall management device 50 (that is, the region) in accordance with the acquired restriction information (restriction contents in the restriction period).

The allocation target selection unit 834 selects one or more management devices 50 in order to allocate the calculated overall suppressed power generation amount. That is, since the efficiency as a whole is reduced when the power generation facilities 10 are individually restricted, for example, the restriction contents are made stronger than those at the time of individual restriction, and the restriction target is assigned to fewer homes. It should be noted that households to which restrictions are assigned will be less burdensome, such as a rotation system.

The restriction information update unit 835 changes the restriction contents in the restriction period for the power conditioner 12 managed by the selected management device 50. Further, the restriction information update unit 835 cancels the restriction period for the power conditioners 12 managed by the other management apparatus 50 excluding the selected management device.

Hereinafter, the operation of the overall management apparatus 80 (control unit 83) according to the sixth embodiment of the present invention will be described with reference to FIG. FIG. 22 is a flowchart illustrating an example of the restriction information update process executed by the control unit 83.

First, the control unit 83 acquires restriction information (step S501). That is, the restriction information acquisition unit 831 acquires the restriction information 71 described above from the server 70.

The control unit 83 acquires power generation facility information (step S502). That is, information regarding the power generation facility 10 is collected from the management device 50.

The control unit 83 calculates the total suppression power amount that needs to be restricted within the area (step S503). That is, the total suppressed power generation amount calculation unit 833 calculates the total suppressed power generation amount whose output should be limited in the overall management device 50 according to the acquired restriction information (content of restriction in the restriction period).

The control unit 83 selects one or more management devices 50 in order to allocate the total suppression power amount (step S504). That is, the allocation target selection unit 834 selects one or more management devices 50 (that is, houses) in order to allocate the overall suppressed power generation amount calculated in step S503.

The control unit 83 requests the selected management device 50 to update the restriction content during the restriction period (step S505). That is, the restriction information update unit 835 changes the restriction content in the restriction period for the power conditioner 12 managed by the management device 50 selected in step S504.

The control unit 83 requests the other management devices 50 other than the selected management device 50 to cancel the restriction period (step S506). That is, the restriction information update unit 835 cancels the restriction period for the power conditioners 12 managed by the other management devices 50 excluding the management device 50 selected in step S504.

制限 With this restriction information update process, power can be used effectively throughout the region.
