Description

  The present invention relates to a management apparatus for equipment, a management system, a program, and a recording medium.

  Conventionally, in order to avoid the situation where the power supply is short when the amount of power consumption temporarily rises and the supply of power becomes tight in summer, etc., the air conditioner from the main body on the power supply side There has been devised a system that makes a demand control request (an adjustment request for power consumption) that promotes suppression of power consumption.

  For example, in the system described in Patent Document 1 (Japanese Patent Laid-Open No. 10-30834), when power is tight, a demand control request is received, and the output of the air conditioner is reduced to reduce power consumption. When this is required, attention is paid to the fact that the comfort of the air-conditioned space is significantly deteriorated. In the system described in Patent Document 1, air conditioning is possible as much as possible even when the demand control request is accepted for the purpose of reducing the number of consumers who cancel the demand control request as much as possible because the comfort is impaired. It has been proposed to perform control so as not to impair the comfort of the target space.

  In this way, in contrast to the supply of electric power from the electric power company to each consumer, the electric charge is paid from the consumer to the electric power company as compensation. Here, as a method for determining the electricity rate, for example, there are cases where a plurality of types of rate setting contracts (a plurality of types of rate plans, etc.) are provided based on the schedule of the power consumption amount of each consumer.

  Here, for example, there may be a plurality of types of complicated charge setting contracts such as correcting the electricity charge depending on whether the consumer accepts demand control. Specifically, an operator on the power supply side such as an electric power company may require each customer to temporarily adjust the amount of power consumption when the power supply is tight, etc. The operator on the side may have a contract with each customer so that various incentives are granted so that each customer can respond to the adjustment request of the power consumption as much as possible. As a result, each consumer receives incentives such as lowering charges by responding to requests for adjustment of power consumption, while operators on the power supply side, such as electric power companies, It is possible to obtain a merit that the power generation-related equipment can be made larger than necessary and the power generation-related equipment can be eliminated more than necessary.

  However, in the case where there are a plurality of rate setting contracts in which electricity charges are corrected based on the acceptance of demand control in this way, each consumer chooses an appropriate rate setting contract. It becomes difficult to grasp whether or not it is possible, or the work for grasping becomes complicated.

  The subject of the present invention is made in view of the above-mentioned point, and in the case where the consideration for the consumption of electric power is determined so that a privilege is given to the consumer side by responding to the adjustment request of the electric power consumption An object of the present invention is to provide a management apparatus, management system, program, and recording medium for equipment that can provide useful information to consumers.

(5) Specific example of processing for each customer FIG. 11 shows customers A, B, C, D managed separately for the first team, the second team, and the third team for each type of basic charge setting contract. Taking E, F, G, and H as examples, the occurrence of a penalty when changing the acceptance information 33a and canceling the acceptance schedule of the power consumption adjustment request will be described with an example.

  As shown in FIG. 10, the consumers B and F accept an adjustment request for power consumption and set demand acceptance days within a normal frequency (for example, a range of 8 days or more and less than 20 days in a month). The basic rate setting contract is such that the penalty when canceling is required (correction conditions) and the unit price of electricity charges is normal (basic conditions) I belong to the second team.

  Further, the consumers A, D, and E accept the adjustment request for power consumption and frequently perform demand response control (with a frequency higher than the normal frequency, for example, 20 days or more permissible days per month). The penalty when canceling while being requested (as much as possible) is larger than normal (correction conditions), but the unit price of electricity charges is set lower than the normal case (basic conditions) Belongs to the first team that has a basic fee setting contract.

  In addition, the consumers C, G, and H frequently accept demands for adjusting power consumption and perform demand response control (with a frequency lower than the normal frequency, for example, an acceptable date of acceptance of less than 8 days per month. The penalty when canceling is not required (corrected condition) is smaller than normal (correction conditions), but the unit price of electricity charges is set higher than normal (basic conditions) ) Belongs to the third team that has a basic fee setting contract.

  In any of the above, it is determined in advance that the penalty increases as the timing of cancellation is closer to the implementation date.

  Here, an example of the customer A belonging to the first team in which the unit price of the electricity bill is set to be low by frequently performing demand response control will be described.

  An example in which the customer A cancels the acceptance schedule of the adjustment request for the power consumption amount by changing the acceptability information 33a with reference to FIG.

  The customer A accepts a request for adjusting the power consumption amount, and performs demand response control for reducing the power consumption amount to reduce the power consumption amount through the HEMS input unit 55 one month or more before the “implementation date”. It is assumed that acceptance information 33a is input to the HEMS controller 5. Specifically, the customer A who has a contract belonging to the first team adjusts the power consumption amount on all weekdays (frequency of 20 days or more in a month) from Monday to Friday as acceptance / rejection information 33a. Assume that it is allowed to perform demand response control that accepts a request and reduces power consumption.

  In the central management system 10, it is determined in advance that a cancellation that is less than a predetermined time length immediately before the scheduled execution date (for example, the day before the implementation date) is not accepted. That is, the HEMS input unit 55 is set in advance so that the reception process is not performed even if the schedule change information is input for a predetermined period immediately before the scheduled execution date and time. As a result, for a predetermined period immediately before the scheduled date and time of implementation, each customer can be prevented from being canceled, and the process according to the schedule for accepting the power consumption adjustment request is performed as much as possible, thereby reducing the power consumption. The predictability of quantity can be increased.

  Based on the above assumption, for example, the customer A inputs the schedule change information to the HEMS input unit 55 between one month and four weeks before the implementation date in which the acceptance is permitted in the acceptance information 33a. Suppose that you cancel the acceptance. In this case, since the customer A has a basic fee setting contract that is cheaper than the normal unit price of electricity, a larger penalty is incurred as a penalty for cancellation, but the timing of cancellation For cases where is 4 weeks ago, there will be a long time left until the implementation date, so the penalty will be adjusted so as not to increase. Specifically, when the HEMS input unit 55 receives the input of the schedule change information, the HEMS control unit 52 transmits the schedule change information to the aggregator 3 via the communication network 2. Here, the basic consideration information generation unit 32a of the aggregator control unit 32 is based on the fee contract information 33b stored in the aggregator storage unit 33, and generates electricity according to the basic fee setting contract currently contracted by the customer A. The unit price (specific basic condition) of the charge is specified, and the basic charge (basic consideration information) for the month is generated based on the power consumption data acquired from the smart meter 6 via the communication network 2 or the like. Next, the corrected consideration information generation unit 32b specifies the presence / absence of cancellation and the date / time of cancellation based on the history information 33c. Then, the corrected consideration information generation unit 32b specifies the magnitude of the penalty value based on both the type of the basic fee setting contract and the timing at which the cancellation is performed based on the fee contract information 33b for the specified cancellation. (Specify based on specific correction conditions.) Based on the penalty value specified above, the basic charge (basic consideration information) for the month is corrected, and the electricity charge (corrected consideration information) for the month is generated.

  For example, in the case of canceling both Monday and Tuesday two weeks ago, the corrected consideration information generation unit 32b specifies the cancellation value based on both the type of the basic fee setting contract and the timing at which the cancellation was performed. Then, a process of adding an amount twice (two days) of the specified penalty value to the basic charge for the month is performed.

  Further, it is assumed that the schedule change information is input to the HEMS input unit 55 and canceled for one day of the week one week before the implementation date that the customer A has accepted in the acceptability information 33a. . In this case, a large penalty corresponding to the cancellation one week before that is larger than the small penalty corresponding to the cancellation four weeks ago occurs. Specifically, when the HEMS input unit 55 receives the input of the schedule change information, the HEMS control unit 52 transmits the schedule change information to the aggregator 3 via the communication network 2. As a result, the corrected consideration information generation unit 32b of the aggregator control unit 32 performs processing for adding the amount of a large penalty value one week ago to the basic charge for the month.

  In the above example, the basic consideration information generation unit 32a of the aggregator 3 reads out the unit price of the relatively low electricity rate stored in the aggregator storage unit 33 so as to correspond to the type of the basic rate setting contract of the first team. Then, the measurement data of the power consumption acquired by the smart meter 6 and transmitted to the aggregator 3 is read. Then, the basic consideration information generation unit 32a of the aggregator 3 multiplies the unit price of the electricity price by the total power consumption of the month ascertained from the measurement data of the power consumption, thereby obtaining the basic of the customer A in the month. Calculate the fee. Further, the corrected consideration information generation unit 32b of the aggregator 3 cancels the two days canceled at the time four weeks ago and the time one week before the implementation date allowed to be accepted in the above-described acceptance information 33a. Calculate the total penalty amount for the day canceled with. Specifically, the corrected consideration information generation unit 32b of the aggregator 3 classifies the two days canceled at the time of four weeks ago in the aggregator storage unit 33 as a category of the unit price of the basic rate setting contract with a low unit price. The penalty value stored in the category corresponding to the cancellation four weeks ago is read, and the penalty value is multiplied by 2 corresponding to two days, and the penalty corresponding to the cancellation for two days four weeks ago Calculate the amount. Further, the corrected consideration information generation unit 32b cancels the one-day cancellation for one day before, in the aggregator storage unit 33, in the category of the unit price of the basic charge setting contract with the lowest unit price of the electricity charge and one week in advance. The penalty value stored in the corresponding category is read, and the penalty value is multiplied by 1 corresponding to one day to calculate the penalty amount corresponding to the cancellation for one day before one week. Here, the corrected consideration information generation unit 32b sums the penalty amount corresponding to the cancellation for two days four weeks ago and the penalty amount corresponding to the cancellation for one day one week ago. Calculate the penalty amount. Then, the corrected compensation information generation unit 32b of the aggregator 3 calculates the electricity charge for the customer A in the month by adding the total penalty amount to the basic charge for the customer A in the month.

  In addition, the electricity bill calculated by the corrected consideration information generation unit 32b in this way is transmitted to the corresponding customer's HEMS controller 5 via the communication network 2 and the gateway 4. The HEMS control unit 52 of the HEMS controller 5 causes the HEMS output unit 56 to display and output the received electricity bill.

(6) Flowchart of Control Processing for Power Consumption Adjustment Request FIG. 12 shows the flow of control processing for the power consumption adjustment request in the central management system 10 described above.

  In step S <b> 11, has the aggregator control unit 32 of the aggregator 3 accepted the acceptance / rejection information 33 a input by the customer via the HEMS input unit 55 of the HEMS controller 5 by being stored in the aggregator storage unit 33? Judge whether or not. If the acceptability information 33a is accepted here, the process proceeds to step S12. Here, the HEMS control unit 52 stores the acceptability information 33 a input by the customer via the HEMS input unit 55 of the HEMS controller 5 in the HEMS storage unit 53.

  In step S <b> 12, the aggregator control unit 32 of the aggregator 3 determines whether there is schedule change information input by the customer via the HEMS input unit 55 of the HEMS controller 5. If it is determined that the schedule change information exists, the process proceeds to step S13. If it is determined that the schedule change information does not exist, the process proceeds to step S14. Here, when the customer inputs the schedule change information via the HEMS input unit 55 of the HEMS controller 5, the HEMS control unit 52 overwrites the acceptability information 33 a stored in the HEMS storage unit 53. Let

  In step S <b> 13, the aggregator control unit 32 overwrites the acceptability information 33 a stored in the aggregator storage unit 33 based on the schedule change information. Whether the schedule change information indicates that “if a power consumption adjustment request occurs at the scheduled date and time, the schedule that was supposed to be rejected is changed to be accepted” , "If a request for adjusting the power consumption occurs at the scheduled date and time, change the plan that was supposed to be accepted so that it will not be accepted", that is, whether to indicate cancellation To do. If it indicates cancellation, the aggregator control unit 32 causes the aggregator storage unit 33 to store information specifying the time when the schedule change information is received as cancellation history information 33c. As a result, it is possible to grasp information indicating how long the cancellation was accepted at the stage before the scheduled date of implementation.

  In step S14, the aggregator control unit 32 determines whether or not it is time to calculate the electricity bill. For example, in the case of a contract in which the electricity rate is fixed once a month, it is confirmed whether or not the timing is once a month. If it is time to calculate the electricity bill, the process proceeds to step S15. If it is not time to calculate the electricity bill, the process proceeds to step S16.

  In step S15, the aggregator control unit 32 performs an electricity bill calculation output process, which will be described later, and proceeds to step S16.

  In step S <b> 16, the aggregator control unit 32 determines whether a power consumption amount adjustment request from the power company 1 is currently received. If not, the process returns to step S11 and the above process is repeated. If accepted, the aggregator control unit 32 causes the aggregator storage unit 33 to store the date and time when the adjustment request for the power consumption is received. This makes it possible to grasp the date and time when the request for adjusting the power consumption occurs.

  Here, the HEMS control unit 52 also determines whether or not an adjustment request for power consumption from the power company 1 has been received. The power consumption amount adjustment request from the power company 1 may be received by the HEMS controller 5 via the communication network 2 and the gateway 4, or the HEMS controller 5 via the aggregator 3 and the communication network 2. May have been received.

  In step S <b> 17, the HEMS control unit 52 is based on the latest acceptability information 33 a stored in the HEMS storage unit 53, “Does it intend to respond when a request for adjusting the power consumption occurs?” It is determined whether or not it is permitted. If it is not permitted, the process proceeds to step S18. If it is permitted, the process proceeds to step S19.

  In step S18, the HEMS control unit 52 continues the control of the equipment such as the electrical appliance 8 and the heat pump 7 by the normal control instead of the demand response control that reduces the power consumption, and returns to step S11. .

  In step S <b> 19, the HEMS control unit 52 starts to control the equipment such as the electrical appliance 8 and the heat pump 7 by demand response control with reduced power consumption.

  In step S <b> 20, the HEMS control unit 52 determines whether or not a suppression period for which suppression of power consumption is required has elapsed with respect to the power consumption adjustment request grasped in step S <b> 16. If it has elapsed, the process proceeds to step S21.

  In step S21, the HEMS control unit 52 ends the demand response control and starts the normal control. Further, the HEMS control unit 52 stores in the HEMS storage unit 53 that it has responded to the adjustment request for the power consumption, and transmits it to the aggregator 3 via the communication network 2. The aggregator control unit 32 stores in the aggregator storage unit 33 the response to the adjustment request for the power consumption and the date and time. After performing the above process, the process returns to step S11 to repeat the process.

(7) Flowchart of power charge calculation output process FIG. 13 shows the flow of the power charge calculation output process described above.

  In step S31, the aggregator control unit 32 identifies the type of basic charge setting contract of the customer stored in advance in the aggregator storage unit 33, and is stored in advance in the aggregator storage unit 33 according to the type. Read the unit price of the electricity bill.

  In step S <b> 32, the aggregator control unit 32 reads out data corresponding to the consumer from the measurement data of the power consumption obtained by the smart meter 6 and stored in the aggregator storage unit 33.

  In step S33, the aggregator control unit 32 calculates a basic fee by multiplying the unit price read in step S31 by the total power consumption for the predetermined period (for example, one month) read in step S32.

  In step S <b> 34, the aggregator control unit 32 determines whether or not the cancel history information 33 c is recorded in the aggregator storage unit 33. If the cancel history information 33c is not recorded, the process proceeds to step S39. If the cancel history information 33c is recorded, the process proceeds to step S35.

  In step S <b> 35, the aggregator control unit 32 specifies the time when the schedule change information is accepted based on the cancellation history information 33 c recorded in the aggregator storage unit 33. Further, when the schedule change information is received a plurality of times, each time period and the number of times corresponding to each time period are specified.

  In step S <b> 36, the aggregator control unit 32 specifies a penalty value stored in advance in the aggregator storage unit 33 according to the basic fee setting contract and the schedule change information reception timing. In addition, when the cancellation exists several times, it specifies for every cancellation.

  In step S37, the aggregator control unit 32 calculates the cancellation amount by multiplying the cancellation value specified in step S36 by the number of cancellations at the time corresponding to the cancellation value. If cancellation has occurred at a plurality of periods, the total value of values obtained by multiplying the number of cancellations at the period corresponding to each cancellation value is calculated as the cancellation amount.

  In step S38, the aggregator control unit 32 adds the cancellation amount calculated in step S37 to the basic fee calculated in step S33, calculates an electricity rate, and proceeds to step S40.

  In step S39, the aggregator control part 32 performs the process which makes the basic charge calculated in step S33 the electric charge, and transfers to step S40.

  In step S40, the aggregator control unit 32 stores the calculated electricity bill in the aggregator storage unit 33 and also outputs it. The output here may be, for example, a printout of a bill sent to the consumer, or by transmitting information on the electricity bill from the aggregator 3 to the HEMS controller 5 of the consumer. There may be. When the HEMS controller 5 receives the electricity bill, the HEMS output unit 56 displays and outputs the electricity bill.

(8) Flowchart of Basic Charge Setting Contract Type Change Proposal Process The flow of the basic charge setting contract type change proposal process in the centralized management system 10 is shown in FIG.

  In step S51, the condition selection unit 32c of the aggregator control unit 32 determines whether or not a predetermined selection start condition set in advance is satisfied. Specifically, in this example, the condition selection unit 32c determines whether or not the date and time set in advance as the time for reviewing the contract within a year. If the time is satisfied, the process proceeds to step S52.

  In step S52, the condition selection unit 32c of the aggregator control unit 32 reads the data from the time when the basic fee setting contract was last changed to the present in the history information 33c stored in the aggregator storage unit 33. The process proceeds to step S53.

  In step S53, the condition selection unit 32c of the aggregator control unit 32 reads the data from the time when the basic rate setting contract was last changed to the present among the electricity rates stored in the aggregator storage unit 33. Thus, the total value of electricity charges for that period is grasped.

  In step S54, the condition selection unit 32c of the aggregator control unit 32 grasps the past power consumption and the permission status of the power consumption adjustment request based on the history information 33c read in step S52. Specifically, the past acceptance information 33a, the schedule change information, and the power consumption measured by the smart meter 6 are grasped. If the condition selection unit 32c has temporarily selected from a plurality of types of basic charge setting contracts stored in the charge contract information 33b, the condition accepting information 33a, the schedule change information, and the power consumption Select a basic rate setting contract that will reduce the total electricity bill for the period under the same conditions.

  In step S55, the condition selection unit 32c of the aggregator control unit 32 transmits the basic fee setting contract selected in step S54 to the aggregator output unit 35 and transmits it to the HEMS controller 5 via the communication network 2 and the gateway 4. By doing so, a proposal for changing the type of the basic charge setting contract is made to the consumer.

(9) Features of the present embodiment In the aggregator 3 of the centralized management system 10 according to the above embodiment, the condition selection unit 32c of the aggregator control unit 32 makes a basic rate setting contract that can be expected to make the electricity rate cheaper for consumers. Can be selected and proposed to consumers.

For example, the basic principle is that the penalty when canceling while demanding frequent adjustment of demand response by accepting the adjustment request of power consumption is larger than usual, but the unit price of electricity bill is set low For customers who had a price setting contract, cancellations were frequently made based on the history information 33c , and as a result, other basic price setting contracts were able to reduce electricity charges. When it is found out, it is possible to grasp the type of basic charge setting contract that allows the customer to reduce the electricity charge.

  This makes it possible to easily grasp the desired basic charge setting contract even when a complicated charge system is adopted in which the electricity charge fluctuates in response to an adjustment request for power consumption. Become.

  Furthermore, when a customer who knows the type of the basic fee setting contract is changed to the more preferable basic fee setting contract, a team corresponding to the type of the basic fee setting contract (in the above example, the first charge setting contract is the The power consumption characteristics of each consumer belonging to the team, the second team, and the third team) are made uniform for each team. Thereby, the stability of power management (power consumption prediction, etc.) in the aggregator 3 can be improved.

  In addition, since the timing for canceling a schedule for accepting an adjustment request for power consumption is configured so that the cancellation value increases as the execution date is closer, the centralized management system can be used to refrain from cancellation immediately before the execution date. 10, the occurrence of communication congestion immediately before the implementation date can be suppressed.

  As described above, acceptance / rejection information 33a is submitted in advance from the customer, and since cancellation is suppressed, processing close to the schedule can be performed, and in the aggregator 3 Power management (e.g., prediction of power consumption) is facilitated, and the necessity of providing an unnecessarily large-scale power generation facility in the power company 1 can be reduced.

(10) Modification (10-1) Modification A
In the above embodiment, the case where the aggregator program 34 is stored in the aggregator 3 in advance has been described as an example.

  The aggregator 3 is not limited to this. For example, as shown in FIG. 15, such a program is stored via the recording medium 134 in which the aggregator program 34 described above is stored temporarily. You may make it install with respect to the aggregator 3 which was not.

  Further, the aggregator program 34 may be stored in any location connected so as to be downloadable via the communication network 2. That is, the aggregator program 34 may be downloaded and installed via the communication network 2 to an aggregator in which such an aggregator program 34 is not stored.

(10-2) Modification B
In the above-described embodiment, as a cancellation penalty, a system in which a consumer is burdened in the form of adding a penalty amount to the basic fee corresponding to the power consumption during the period has been described as an example.

  However, the cancellation penalty is not limited to this, and for example, an incentive may be generated by another method such as a reduction in the point return rate related to the electricity bill. In addition, for example, the penalty may be given by increasing the unit price of the electricity charge after the next month.

(10-3) Modification C
In the above-described embodiment, the case has been described as an example in which, when the schedule of the date and time that can respond to the adjustment request for the power consumption is canceled, the user is forced to bear the cancellation amount.

  However, the method for suppressing the change of the schedule is not particularly limited. For example, instead of granting the penalty of adding the cancellation amount, the schedule of the date and time that can respond to the power consumption adjustment request for a predetermined period of time If there is no change, a method may be used in which the electricity bill is reduced by performing the operation as scheduled.

(10-4) Modification D
In the above-described embodiment, the mechanism for giving a penalty to the consumer when canceling the schedule of the date and time that can respond to the adjustment request for the power consumption has been described as an example.

  However, if the cancellation date / time has passed without the generation of power consumption adjustment request, the actual power consumption adjustment request has occurred at the canceled date / time without any penalty. Only a penalty may be given.

(10-5) Modification E
The above embodiment has been described by taking as an example the case of presenting a two-choice schedule whether to respond to a request for adjusting the power consumption.

  However, instead of simply selecting whether or not to respond to the adjustment request for the power consumption amount, a schedule may be submitted in which the level of response is divided into a plurality of settings. In other words, both are scheduled to respond to the power consumption adjustment request, but the extent to respond to the power consumption adjustment request at a specific date and the extent to respond to the power consumption adjustment request at another specific date and time. You may make it schedule differently. In this case, for example, the control method of the heat pump 7 is not two choices of normal control and demand response control, and the demand response control may be further divided into a plurality of types of power consumption per unit time.
