Description

  The present invention relates to a control device.

  Conventionally, there is a control device that performs demand control so that the total power consumption for each demand time limit does not exceed the contract power amount determined with the power company. For example, in the control device disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 7-143670), a plurality of air conditioners are predicted so that the power consumption at the end of the demand time period is predicted and the power consumption does not exceed the contract power consumption. Demand control for ensuring user comfort while uniformly changing the set temperature is disclosed.

  In recent years, there is a movement to further reduce the amount of power used in each building. For this reason, the electric power company proposes a system that provides incentives for buildings, etc., that set a target power amount that is smaller than the normal contracted power amount described above, and that keeps the amount of power used at the target power amount in a predetermined time zone. Yes.

  However, in the control device disclosed in Patent Document 1, although demand control is performed in consideration of user comfort, control that considers even incentives is not considered.

  Then, the subject of this invention is providing the control apparatus which can perform the control which considered the incentive.

  The control device according to the first aspect of the present invention pays a penalty that power suppression targeting the first power amount cannot be performed, while performing power suppression targeting a second power amount lower than the first power amount. And a control device that controls facility equipment including an air conditioner in a building where an incentive enters. And the control apparatus which concerns on the 1st viewpoint of this invention is provided with a memory | storage part, a reception part, an electric energy suppression control part, an excess control part, and an acquisition part. The storage unit stores the first electric energy and the second electric energy. The reception unit receives a request time zone for performing the second power suppression control. 2nd electric power suppression control is control which makes the total electric energy used for every demand time limit of an installation apparatus below 2nd electric energy. The excess control unit executes the excess control in a predetermined time zone immediately before the request time zone. The excess control is control that causes the total power consumption for each demand time limit of the equipment to exceed the first power consumption. An acquisition part acquires the information of the excess from the 1st electric energy of the total electric energy used for every demand time limit of equipment in the excess control.

  Here, conventionally, in buildings, control is performed so that the total power consumption for each demand period does not exceed the first power consumption. This is because it is necessary to pay a penalty if the first electric energy is exceeded. Here, for example, the penalty is a fee demerit. In recent years, a system has been proposed in which an incentive is provided when power suppression is performed with the second power amount as a target. Here, for example, the incentive is a merit in charge.

  Therefore, in the present invention, excess control is performed in a predetermined time zone immediately before the request time zone in which the second power suppression control is performed in consideration of the incentive by performing the second power suppression control. That is, for example, when the penalty caused by executing the excess control is less than the incentive entered by executing the second power suppression control, even if the penalty occurs due to executing the excess control, the second power suppression Since an incentive is entered due to the execution of the control and no fee-related disadvantage occurs, when the second power suppression control can be executed, the excess control is executed. Therefore, during execution of the excess control, the user's comfort can be further ensured, and further, the excess control is executed in a predetermined time zone immediately before the execution of the second power suppression control.

After the excess control, the updating unit updates the upper limit value of the total power consumption for each demand time period of the facility device in the first power suppression control to a value obtained by adding the excess amount to the first power amount.

  Here, when the excess control in which the total power consumption for each demand time limit exceeds the first power amount, generally, the first power amount that is the target of power suppression is updated for one year from the following month, and the basic charge is also raised. Will be. And 1st electric power suppression control is performed based on this updated electric energy. However, in the present invention, since the incentive is entered by executing the second power suppression control, the excess control in which the basic charge is increased is performed, and the first power suppression control is executed based on the updated power amount. Even so, it is possible to prevent a fee penalty.

In other words, the power amount suppression control unit 36c performs control so that the total power consumption for each demand time period of the equipment is equal to or less than the first power amount based on the first contract with the power company 1 (excess control in FIG. 5). (See earlier first power suppression control). Specifically, as described above, the total power consumption for each demand period of each device (air conditioner 40, lighting device 50, ventilation device 60, etc.) constituting the facility device is equal to the first power amount or the facility device. Control is performed so that it is less than or equal to the target total power consumption for each demand period based on operating conditions.

  In step S102, the excess control unit 36d determines whether or not it is a predetermined time before the requested time zone. Specifically, whether the excess control unit 36d is a predetermined time before the request time zone based on the request time zone stored in the request time zone storage area 35c and the time measured by the timer unit 34. It is determined whether or not. Here, the predetermined time is an arbitrary time stored in a predetermined storage area in advance, for example, one hour. Note that the predetermined time may be changed as needed based on the operating status of the equipment stored in the operating status storage area 35a, the predicted status (predicted power consumption) in the required time zone based on the operating status, and the like. If it is determined that it is a predetermined time before the requested time zone, the process proceeds to step S103, and the excess control unit 36d causes the power amount suppression control unit 36c to end the execution of the first power suppression control and executes the excess control. (See the excess control in FIG. 5). In the excess control, the total power consumption for each demand time limit of the equipment is made to exceed the first power consumption. More specifically, the total power consumption for each demand time limit of the equipment is controlled to be equal to or less than the value obtained by adding the first power amount and the excess amount. More specifically, as described above, in the excess control, the total power consumption for each demand time period of the air conditioner 40 included in the equipment is calculated as the target total use for each demand time period during the execution of the first power suppression control. Control is performed so as to be equal to or less than the sum of the electric energy and the excess. On the other hand, when it is determined in step S102 that the predetermined time before the requested time zone has not been reached, the excess control unit 36d instructs the power amount suppression control unit 36c to repeat the process of step S101. In other words, in the present embodiment, the first power suppression control is executed until a predetermined time before the request time zone, and when the predetermined time before the request time zone is reached, the first power suppression control is terminated and exceeded. Control is being executed.

  In step S104, the power amount suppression control unit 36c determines whether or not the start time of the requested time zone has come. Specifically, the power amount suppression control unit 36c determines whether or not the requested time zone start time is based on the requested time zone stored in the requested time zone storage area 35c and the time measured by the timer unit 34. Judging. If it is determined that the start time of the requested time zone has been reached, in step S105, the excess control unit 36d terminates the execution of the excess control of the facility device, and in step S106, the second power suppression of the facility device is performed. The control is executed (see the second power suppression control in FIG. 5). That is, in step S106, the power amount suppression control unit 36c performs control so that the total power consumption for each demand time period of the equipment is equal to or less than the second power amount based on the second contract with the power company 1. More specifically, as described above, the total power consumption for each demand period of each device (air conditioner 40, lighting device 50, ventilation device 60, etc.) constituting the facility device is the second power amount or the facility device. It is controlled so that it is less than or equal to the target total power consumption for each demand time period based on the driving situation. On the other hand, if it is determined in step S104 that the start time of the requested time zone has not been reached, the power amount suppression control unit 36c instructs the excess control unit 36d to continue the excess control (step S104). The process of S103 is executed). That is, in the present embodiment, excess control is executed from a predetermined time before the request time zone to the start time of the request time zone. When the start time of the request time zone is reached, the excess control is terminated and the second power Suppression control is being executed.

  In step S107, the power amount suppression control unit 36c determines whether or not the end time of the requested time period has come. Specifically, the power amount suppression control unit 36c determines whether or not the end time of the requested time zone based on the requested time zone stored in the requested time zone storage area 35c and the time measured by the timer unit 34. Judging. If it is determined that the end time of the requested time zone has been reached, the second power suppression control is terminated in step S108, and the process returns to step S101 to execute the first power suppression control (the requested time zone in FIG. 5). Refer to the subsequent first power suppression control). On the other hand, when it is determined in step S107 that the end time of the requested time zone has not been reached, the process of step S106 is repeated. That is, the second power suppression control is continuously executed.

(6) Features (6-1)
In the equipment control system 100 of the present embodiment, the buildings A and B pay a penalty if the power suppression targeted for the first power amount cannot be performed, and target the second power amount lower than the first power amount. It is assumed that incentives will be provided when power is suppressed. Specifically, buildings A and B have signed a first contract with power company 1 regarding power suppression targeting the first power amount and a second contract regarding power suppression targeting the second power amount. It is out. The first contract is a contract in which the buildings A and B pay a penalty to the power company 1 if the power control cannot be performed. The second contract is a contract in which an incentive from the power company 1 is entered into the buildings A and B when power is suppressed.

  And in the buildings A and B, as a premise, the control device 30 executes the first power suppression control of the facility equipment based on the first contract. However, since the buildings A and B have a second contract with the power company 1, exceptionally, the second power suppression control of the equipment is executed when the requested time zone is reached. Then, by executing this second power suppression control, incentives are entered from the power company 1 into the buildings A and B. Therefore, in addition, in exceptional cases, a predetermined time zone immediately before the request time zone (ie, The equipment equipment excess control is executed during a predetermined time before the request time zone to the start time of the request time zone. Furthermore, in this embodiment, an administrator or the like can input an excess from the first power amount of the total power consumption for each demand time period of the equipment device in the excess control via the input unit 33. In the present embodiment, in the excess control, the target total power consumption for each demand period of the air conditioner 40 is increased by the excess amount. Thus, for example, if the administrator or the like inputs a number greater than 0 as the excess, the user's comfort regarding the air-conditioning environment is ensured during the execution of the excess control.

  In the present embodiment, the excess control is executed in a predetermined time zone immediately before the execution time zone (request time zone) of the second power suppression control. Therefore, during execution of the second power suppression control, the user regarding the air conditioning environment It is possible to suppress the decrease in comfort as much as possible.

  As described above, in the present embodiment, it is possible to execute control corresponding to a system that has been proposed in recent years, that is, a system that takes incentives into consideration.

(6-2)
In the present embodiment, the derivation unit 36e is based on the information on the incentive and the information on the penalty stored in the contract information storage area 35b of the storage unit 35. Situational relationships are derived. The derived excess-money status relationship is stored in the excess-money status storage area 35d of the storage unit 35 and displayed on the display unit 32 by the output unit 36f.

  As described above, in the present embodiment, the administrator or the like can visually recognize the predetermined excess and the corresponding monetary status via the display unit 32. In other words, the administrator, etc., in the excess control, how much the total power consumption per demand time period of the equipment is exceeded from the first power amount, that is, how much the excess amount is, how much plus It is possible to grasp whether it will be negative or negative. Therefore, the administrator or the like can determine the excess from the first power amount of the total power consumption for each demand time period related to the equipment in the excess control by looking at the relationship between the excess amount and the money situation. As described above, in this embodiment, the administrator or the like can determine the balance between the comfort and the price.

(6-3)
In the present embodiment, the excess control unit 36d cancels the thermo-off control of the air conditioner 40 in the excess control.

  As described above, during the excess control, even if the set temperature is reached, the thermo-off is not performed, so that heat can be continuously stored in the room as the air-conditioning target space by the air-conditioning of the air conditioner 40. Therefore, the user's discomfort regarding the air-conditioning environment can be reduced during the execution of the second power suppression control executed after the end of the excess control.

(7) Modifications The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to the above-described embodiment, and can be changed without departing from the gist of the invention. .

(7-1) Modification A
In the above-described embodiment, it has been described that the first power suppression control of the facility device is executed after the request time period ends. However, the present invention is not limited to this. You may comprise so that control may be performed.

  Hereinafter, a specific processing flow in the control device 30 according to the present modification will be described with reference to FIGS. 6 and 7. FIG. 6 is a flowchart showing the flow of processing in the control device 30 according to Modification A. FIG. 7 is a graph showing a part of the transition of the electric energy in the buildings A and B according to the modified example A. Here, since steps S111 to S118 in FIG. 6 are the same processing as in the above embodiment, description thereof will be omitted, and only steps S119 to S121 that are different from the above embodiment will be described.

  In step S119, the power amount suppression control unit 36c instructs the excess control unit 36d to execute excess control of the equipment. That is, in this modification, the excess control of the equipment is executed immediately after the request time period.

  In step S120, the excess control unit 36d determines whether or not a predetermined time has elapsed from the end time of the requested time period. Specifically, the excess control unit 36d sets a predetermined time from the end time of the request time zone based on the request time zone stored in the request time zone storage area 35c and the time measured by the timer unit 34. It is determined whether or not it has passed. Here, the predetermined time is an arbitrary time stored in a predetermined storage area in advance, for example, one hour. Note that the predetermined time may be changed as needed based on the operating status of the equipment stored in the operating status storage area 35a, the predicted status (predicted power consumption) in the required time zone based on the operating status, and the like. And when determining with having passed predetermined time, it transfers to step S121, the excess control part 36d complete | finishes the excess control of an installation apparatus, and also the electric energy suppression control part 36c is the 1st electric power of an installation apparatus. An instruction is given to execute the suppression control (step S111). On the other hand, when it is determined that the predetermined time has not elapsed, the excess control of the equipment is continuously executed. In this way, in this modification, as shown in FIG. 7, not only the predetermined time zone immediately before the request time zone, but also the predetermined time zone immediately after the request time zone (that is, the predetermined time zone from the end time of the request time zone). Excessive control of equipment is executed until the time elapses).

  Thereby, the user's discomfort regarding the air-conditioning environment in the required time zone due to the execution of the second power suppression control can be recovered as soon as possible.

(7-2) Modification B
In the above embodiment, it is described that the excess control is executed only in a predetermined time zone immediately before the request time zone, and in the modification A, the excess control is executed only in the predetermined time zone immediately before / after the request time zone. It is not limited to this. For example, the control device 130 having the configuration shown in FIG. 8 may be used so as to perform the processing shown in FIG. Hereinafter, based on FIGS. 8-10, the structure of the control apparatus 130 which concerns on this modification, and the flow of a process are demonstrated. The difference of the control device 130 from the control device 30 is that the control unit 36 further functions as the update unit 36g (see FIG. 8), and therefore, only the configuration will be described. Further, regarding the flow of processing, steps S131 to S134 in FIG. 9 are the same as steps S101 to S104 in the above embodiment, and steps S136 to S139 in FIG. 9 are steps S105 to S139 in the above embodiment. Since this is the same as S108, description thereof will be omitted, and only step S135 will be described.

<Configuration>
The update unit 36g updates the upper limit value of the total power consumption for each demand time period of the facility device in the first power suppression control to a value obtained by adding the excess amount to the first power amount after the requested time period. Therefore, in the first power suppression control after the request time zone, the total power consumption for each demand time period of the equipment is controlled to be equal to or less than the value obtained by adding the excess amount to the first power amount.

<Process flow>
In step S135, the update unit 36g updates the upper limit value of the total power consumption for each demand time period of the facility device from the first power amount to a value obtained by adding the excess amount to the first power amount. Therefore, in step S131, the power suppression of the equipment is executed with the updated value as a target. That is, in the first power suppression control after the excess control, the power amount is set to be equal to or less than the updated value. The suppression control unit 36c controls the total power consumption for each demand time period of the equipment (see FIG. 10). In addition, about the method of 1st electric power suppression control, it is the same as that of the said embodiment. Here, the update of the upper limit value of the total power consumption for each demand time period by the update unit 36g may be performed immediately after the start of excess control or after the end of excess control. That is, this update may be performed after the excess control.

  Here, generally, when the total power consumption for each demand period exceeds the first power amount, the first power suppression control is executed with the exceeded value as a target, and the basic charge is often raised. Therefore, as in the above-described embodiment, when it is not premised that the first power suppression control targeting the first power amount that is initially set as the power company 1 is performed, In consideration of the user's comfort, the first power suppression control may be executed in a time zone other than the requested time zone, with the target being a value obtained by adding an excess amount to the first power amount.

  Even in this case, since the incentive is given to the buildings A and B by executing the second power suppression control, the excess control for raising the basic charge is performed, and the first power based on the updated power amount is performed. Even if the power suppression control is executed, it is possible to prevent a penalty from being caused.

(7-3) Modification C
In the excess control of the above embodiment, the excess control unit 36d may further execute the housing heat storage control of the air conditioner 40. Specifically, the excess control unit 36d may transmit a command for executing excess control and a command for executing enclosure heat storage control to the control unit of the air conditioner 40. Here, the frame heat storage control is control for storing heat in the frame. As the housing heat storage control, for example, it is conceivable that the direction of the flaps of the indoor units constituting the air conditioner 40 is blown horizontally to accumulate heat in the housing, that is, the building housing is used as a heat storage medium.

  In this way, during the second power suppression control is being performed (requested time zone) by storing heat in the enclosure in the excess control unit in a predetermined time zone immediately before the requested time zone in which the second power suppression control is executed. User discomfort regarding the air-conditioning environment can be reduced. Moreover, since the building frame is used as a heat storage medium, it is not necessary to separately provide a heat storage device and the cost can be suppressed.

(7-4) Modification D
In the above-described embodiment, it has been described that the excess-monetary situation relationship derived by the deriving unit 36e is displayed on the display unit 32 by the output unit 36f. However, the method output by the output unit 36f is displayed on the display unit 32. It is not limited to the displayed method. For example, the excess-monetary status relationship may be printed on a paper medium, or may be sent by e-mail to a computer owned by an administrator or the like in buildings A and B. Even in this case, the control device 30 is configured so that an administrator or the like can input the excess from the first power amount of the total power consumption for each demand time limit in the excess control via the input unit 33. If this is the case, the same effects as those of the above-described embodiment can be obtained.

(7-5) Modification E
In the above-described embodiment, as an example of information related to incentives, an example has been described in which the second power suppression control is executed once for 300 yen. However, the present invention is not limited to this, and is not limited to this. Information for which a fee is set may be used. In this case, the deriving unit 36e derives the incentive from the information related to the incentive and the requested time zone (specifically, the time from the start time to the end time of the requested time zone).

(7-6) Modification F
In the above-described embodiment, it has been described that the acquisition unit 36a acquires the excess information input via the input unit 33 by the administrator or the like, but is not limited thereto.

  For example, you may add the function of a calculation part (not shown) to the control part of the control apparatus of the said embodiment. Specifically, the calculation unit calculates a predetermined time zone immediately before the requested time zone, that is, an excess amount in the excess control, from the equipment device status and the history of the equipment status stored in the operation status storage area. .

  Then, the acquisition unit acquires the excess information calculated by the calculation unit.

  Thus, in this modification, since an excess can be determined based on the past history and the situation of real-time equipment, excess control that contributes to the user's comfort can be executed.

(7-7) Modification G
In the excess control of the above-described embodiment, it has been described that the thermo-off control of the air conditioner 40 is cancelled. However, instead of this, the set temperature control of the air conditioner 40 (indoor unit 42) may be performed.

  The set temperature control is control for decreasing the set temperature of the air conditioner 40 (indoor unit 42) during the cooling operation and increasing the set temperature of the air conditioner 40 (indoor unit 42) during the heating operation. That is, it is control to prevent the thermo-off.

  Thus, by performing the set temperature control of the air conditioner 40 during the excess control, heat can be continuously stored in the room as the air-conditioning target space by the air conditioning of the air conditioner 40. Therefore, similarly to the above-described embodiment, the user's discomfort regarding the air-conditioning environment can be reduced during the execution of the second power suppression control executed after the end of the excess control.

  The present invention concludes a first contract with a power company regarding power suppression targeting a first power amount and a second contract regarding power suppression targeting a second power amount lower than the first target power. In addition, when the power suppression in the second contract is performed, an incentive is entered. On the other hand, the present invention can be variously applied to a control device that controls equipment including an air conditioner in a building that pays a penalty if the power suppression in the first contract cannot be performed.
