Description

  The present invention relates to a power management system, a power management method, and a program for managing the power of a plurality of consumers.

  When implementing demand response, the aggregator recruits customers who cooperate in demand response (power suppression) in advance. Then, the power consumption that can be suppressed based on the recruitment result is estimated, and the target power suppression amount is contracted with the power company. If the contracted target power limit cannot be achieved, the aggregator must pay a penalty to the power company. Therefore, the aggregator sequentially estimates power consumption before or during demand response (power suppression) activation, and if it determines that the contracted target power suppression amount has not been reached, adds a customer who can cooperate with demand response Recruitment has been achieved to achieve the target power reduction.

  For example, when the consumer is a household, the HEMS aggregator that manages multiple households has a large influence on fluctuations in power consumption, depending on whether the householder is at home, going out, waking up or sleeping. Want home information about going out. In the conventional control device, control method and computer program, the householder's home / outing / wake-up / sleeping information is acquired based on the person's own button operation, before the demand response (power suppression) is activated and during the activation The power consumption was estimated using information on staying at home, going out, waking up, and going to sleep in the time of tightness, and it was judged whether the power suppression amount reached the target. Moreover, when the power suppression amount has not reached the target, the home appliances in the absent home are remotely controlled to reduce power (for example, Patent Document 1).

  As a result, the current power consumption estimation accuracy is improved by using the current home / outing / wake-up / sleeping information, and the target power suppression amount is reliably achieved by controlling the home appliances of each household as required. Is possible. Furthermore, since power saving control is performed only for the homes that are out, the decline in the comfort of the householders is minimal.

JP 2014-95947 A

  When recruiting additional customers who cannot achieve the target power reduction amount and can cooperate in demand response (power suppression), demand for households that are likely to reduce power consumption due to going out or going to bed. The possibility of cooperating will be higher if you add additional responses. However, in the control device, the control method, and the computer program described in Patent Document 1, information that correlates with changes in power consumption such as going out, staying at home, sleeping, and going home is used for additional recruitment for demand response cooperation. In addition, additional recruitment at an effective timing such as going out or sleeping was not made.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a power management system, a power management method, and a program that can achieve the target power suppression amount more reliably.

  The power consumption storage unit 106, the weather information storage unit 107, the home appliance operation information storage unit 108, the suppression request entrustment information storage unit 109, and the power consumption pattern information storage unit 110 are not necessarily required for the aggregator-side power management apparatus 100. Not necessarily. That is, there is a storage device outside the device, the home power management device 200 has a storage device, and each of the acquisition units 101 to 105 receives necessary data for the power suppression amount estimation unit 111 and the suppression request generation unit 112. When the data can be acquired collectively, the power consumption storage unit 106, the weather information storage unit 107, the home appliance operation information storage unit 108, the suppression request entrustment information storage unit 109, and the power consumption pattern information storage unit 110 are not necessary.

  The power suppression amount estimation unit 111 estimates the future power suppression amount of each home from the transition of the future power consumption of each home (customer). When estimating the power suppression amount, the current power consumption amount stored in the power consumption amount storage unit 106, the weather result data and weather forecast data of the corresponding region stored in the weather information storage unit 107, home appliances Operation history of home appliances stored in the operation information storage unit 108 to date, scheduled operation schedules in the future, consignment status of suppression requests for each home stored in the consignment request entrustment information storage unit 109, power consumption pattern The power consumption pattern up to the present time of each home stored in the information storage unit 110 is used.

  Note that the period of the power consumption estimated by the power suppression amount estimation unit 111 may be, for example, from the current time to the end time of demand response (power suppression). Further, it may be from the start time to the end time of demand response (power suppression) instead of from the present time. Further, it may be estimated until 24 o'clock on the current day, not until the end time of demand response (power suppression).

  The suppression request generation unit 112 generates suppression request information related to power usage and sends it to each home. The power usage suppression request information generated (or sent) by the suppression request generation unit 112 restricts the time zone when the aggregator wants to suppress power, the amount of power that the aggregator wants to reduce, the reward when cooperating with power suppression, and the use Home appliance information you want. When generating the suppression request, the power suppression amount estimation value received from the power suppression amount estimation unit 111, the target power suppression amount predetermined by the prior contract between the aggregator and the power company, and the power consumption pattern information storage unit 110 The stored power consumption pattern information of each household and the suppression request entrustment information stored in the suppression request entrustment information storage unit 109 are used.

  The power consumption measuring unit 201 of the home-side power management apparatus 200 (customer-side power management apparatus) measures the power consumption of each home (customer). For measurement, a distribution board, watt-hour meter (power meter or smart meter), etc. are used.

  The home appliance operation information measurement unit 202 measures operation information of home appliances in each household. The operation information includes, for example, an operation result of each home appliance, an operation schedule of each home appliance already registered, and the like.

  The power consumption pattern information input unit 203 is an input unit for a householder to input information related to a consumer's behavior related to a change in power consumption. The information related to the change in power consumption is, for example, information on staying at home, going out, getting up, going to bed, and the like. The aggregator-side power management apparatus 100 can detect that the power consumption pattern will change in the future by inputting these pieces of information at the time of going home, going out, getting up, sleeping, and the like. Note that buttons, a touch panel, a keyboard, and the like are used for input.

  The suppression request entrustment information input unit 204 is an input unit for inputting whether or not the householder entrusts the power suppression request information sent by the aggregator. By having these pieces of information input, the aggregator-side power management apparatus 100 can detect whether or not each home has been entrusted with a suppression request. Note that buttons, a touch panel, a keyboard, and the like are used for input.

  The suppression request display unit 205 displays the power suppression request information generated by the suppression request generation unit 112 of the aggregator-side power management device 100. The content displayed on the suppression request display unit 205 includes the time zone when the aggregator wants to suppress the use of power, the amount of power that the aggregator wants to reduce, the reward when cooperating with the power suppression, the home appliance information that wants to limit the use, and the like. The power suppression request information is displayed using a display or the like.

  FIG. 4 shows an example of the appearance of the home-side power management apparatus 200. As shown in FIG. 4, the home-side power management apparatus 200 has a power consumption pattern information input unit 203, a suppression request entrustment information input unit 204, and a suppression request display unit 205 installed on the exterior. The power consumption pattern information input unit 203 includes buttons for staying at home, going out, waking up, and going to bed, indicating the behavior patterns of consumers. In addition, the suppression request display unit 205 includes buttons regarding acceptance and rejection indicating whether the customer has accepted the power suppression request.

  Moreover, the home side power management apparatus 200 does not necessarily need to be one terminal. For example, the power consumption pattern information input unit 203, the suppression request entrustment information input unit 204, and the suppression request display unit 205 may be configured to use a mobile phone, a smartphone, a tablet, a PC, or the like. Further, the power consumption pattern information input unit 203 may be a terminal different from the suppression request entrustment information input unit 204 and the suppression request display unit 205 using a security company security terminal. When the power consumption pattern information input unit 203 is a security terminal or the like, it is necessary to make the power consumption pattern information reach the aggregator via a security company or the like.

  Next, the flow of operation according to the power management system in this embodiment will be described. FIG. 5 is a flowchart showing the determination process for additional power suppression recruitment executed by the power management system according to the first embodiment of the present invention. In the following description, an example will be described in which the aggregator issues a suppression request when a demand response is activated in advance (the day before, etc.), and each home has already responded to the power suppression request as a consignment / rejection. Further, an example will be described in which the aggregator has already contracted with a power company or the like for a target power suppression amount when a demand response is activated.

  The power suppression additional recruitment determination process is automatically started before the demand response is activated, or is started at an arbitrary timing by the user using a keyboard or the like. The processing is continued until the end time of demand response (power suppression).

  When the power suppression additional recruitment determination process is started, first, it is confirmed whether or not a time zone in which power suppression is required (hereinafter referred to as power suppression time) has ended (step 1). The power suppression time is, for example, a time period in which an electric power company is requesting the aggregator to suppress the power of the consumer due to power tightness.

  If it is still during the power suppression time, the aggregator-side power management apparatus 100 performs data acquisition from each home (step 2). The power consumption acquisition unit 101 acquires the power consumption up to now. The weather information acquisition unit 102 acquires the temperature and humidity up to now. Moreover, forecast values such as future temperature and humidity including the power suppression time are acquired. The home appliance operation information acquisition unit 103 acquires the operation results of each home appliance to date and the planned operation schedule. The suppression request entrustment information acquisition unit 104 acquires information as to whether each household is entrusted with the rejection request or rejects it. The power consumption pattern information acquisition unit 105 acquires the current power consumption pattern information of each home.

It should be noted that the current data acquired by the power consumption acquisition unit 101, the weather information acquisition unit 102, the home appliance operation information acquisition unit 103, and the power consumption pattern information acquisition unit 105 may acquire the difference from the previously acquired amount. And the past data of the period required for the estimation of the electric power consumption of the electric power suppression amount estimation part 111 may be acquired. In addition, regarding the suppression request entrustment information acquisition unit 104, if the entrustment information has already been acquired after sending the suppression request to each home, it is not necessary to acquire it again.

The data acquired by the power consumption acquisition unit 101, the weather information acquisition unit 102, the home appliance operation information acquisition unit 103, the suppression request entrustment information acquisition unit 104, and the power consumption pattern information acquisition unit 105 are the power consumption storage unit 106, the weather information, The information is stored in the storage unit 107, the home appliance operation information storage unit 108, the suppression request entrustment information storage unit 109, and the power consumption pattern information storage unit 110.

After data is acquired by each acquisition unit and stored in each storage unit, the power suppression amount estimation unit 111 estimates how much power consumption can be suppressed in the future (step 3). In estimating the power suppression amount, first, the future power consumption is estimated. As an estimation method, for example, it is possible to estimate by regression analysis using, as an explanatory variable, weather information, home appliance information, suppression request entrustment information, and power consumption pattern information, with the power consumption as in Equation 1 as an objective function. .
Power consumption = α ₁ × Meteorological information + α ₂ × Home appliance information + α ₃ × Control request entrustment information + α ₄ × Power consumption pattern information + ε (Equation 1)

In the regression analysis of Equation 1, past power consumption actual measurement values, meteorological information actual measurement values, home appliance information actual measurement values, suppression request consignment information actual measurement values, and electric consumption pattern information actual measurement values stored in the data storage units 106 to 110 are used. The regression variables α _{1 to} α ₅ and the residual ε are learned. Then, when estimating the power consumption at a certain time, the previously learned regression variables α _{1 to} α ₅ and the residual ε and the weather information, home appliance information, suppression request consignment information, and power consumption pattern information at that time Use forecast values. As the weather information, the weather forecast data at that time may be used. Further, the home appliance information may be used for estimation assuming that the home appliance operating status already scheduled in the home appliance operating schedule or the current operating status continues until that time. The suppression request entrustment information and power consumption pattern information may be used for estimation assuming that the current entrustment status and power consumption pattern will continue in the future. These power consumptions are estimated for each household, or a plurality of households are estimated collectively.

  The power suppression amount can be obtained by the difference between the baseline and the power consumption estimated value. Baseline is the standard power consumption when determining the amount of power suppression for consumers by demand response, and is an estimate of power consumption that should have been used when consumers did not suppress power consumption. It is. This baseline uses a calculation method designated by an electric power company or the like. The calculation method is, for example, High X of Y.

  After estimating the power suppression amount based on the latest acquired data, the suppression request generation unit 112 compares with the target power suppression amount contracted with the electric power company, and determines whether additional suppression requests should be recruited ( Step 4).

  If the power suppression amount estimated value is larger than the target power suppression amount, the power suppression has achieved the target, and there is no need to issue an additional suppression request. In that case, the process returns to step 1 to check whether the power suppression time has ended, and if it has not ended, data acquisition and power suppression amount estimation are tried again. Note that there may be no change in the data that can be acquired even if you attempt to acquire data by returning to Step 1 as soon as the decision for additional power suppression in Step 4 is over, so please wait several minutes or tens of minutes. You may make it return to step 1.

  If the estimated power suppression amount is smaller than the target power suppression amount, the target power suppression amount contracted with the power company cannot be achieved as it is, and there is a possibility that a penalty must be paid. Therefore, additional requests for suppression are recruited to increase the amount of power suppression.

  In the present invention, a change in power consumption pattern is used when an additional power suppression request is issued. For this purpose, first, a change in the power consumption pattern of each home is detected (step 5). The power consumption pattern to be detected is changed by inputting a life pattern such as going out, going home, getting up, going to sleep, etc. by the householder of each household, and the power input by the householder of each household in the power consumption pattern information input unit 203 The consumption pattern information is acquired by the power consumption pattern information acquisition unit 105 of the aggregator-side power management apparatus, and the suppression request generation unit 112 acquires the power consumption pattern information acquired by the power consumption pattern information acquisition unit 105 to obtain the power consumption pattern information. Detect changes.

  Next, after detecting a change in the power consumption pattern, the suppression request generation unit 112 creates power suppression request information suitable for each change, that is, in accordance with the change in the power consumption pattern, and uses the power suppression request information as power. It is sent to each customer whose consumption pattern has been changed (step 6). For example, if it is detected that the power consumption pattern has been changed from home to going out (a householder has pressed the go-out button), create power suppression request information requesting to cooperate in power suppression using the outing time And send it to the home. FIG. 6 is an example of a power suppression request sent by the aggregator-side power management terminal when a family member presses the outing button of the power consumption pattern information input unit 203. The sent message (power suppression request information) is displayed on the suppression request display screen. It should be noted that the suppression request information to be sent to the home is sent together with the time for which power cooperation is desired and the suppression cooperation fee (incentive) as shown in FIG. 6 and displayed on the suppression request display screen. Good.

  FIG. 7 is a diagram illustrating an example of the power suppression request information that is generated and sent by the aggregator-side power management terminal 100 and displayed on the home-side power management device 200 when the householder presses the go-out button. As shown in FIG. 7, for example, as pattern A, a cooperation fee for power suppression for 1 hour is displayed, as pattern B, a cooperation fee for power suppression for 2 hours is displayed, and as pattern C, for power suppression for 3 hours. The cooperation fee can be displayed. As described above, a power suppression request regarding a plurality of patterns of power suppression time and reward amount may be set step by step so that it can be selected in accordance with the length of the outing time of the householder.

  In addition, for example, when it is detected that the power consumption pattern has been changed from going out to home (a householder has pressed the home button), in order to suppress the increase in power consumption after returning home, It creates power suppression request information that requests to limit and cooperate in power suppression, and sends it to the home. FIG. 8 is an example of a power suppression request that the aggregator-side power management terminal 100 sends to the home-side power management device when the householder presses the return button of the power consumption pattern information input unit 203. The transmitted power suppression request (power suppression request information) is displayed on the suppression request display screen. In addition, to the power suppression request sent to the home, please send together with the household appliance information that you want the householder to suppress power, the home appliance information that you want to limit for suppression, and the suppression cooperation fee (incentive) as shown in FIG. Also good.

  FIG. 9 is a diagram illustrating an example of a plurality of patterns of suppression requests that are generated and sent by the aggregator-side power management terminal 100 and displayed on the home-side power management apparatus 200 when the home person presses the return button. As shown in FIG. 9, for example, as pattern A, the cooperation fee when the use of lighting and air conditioning in the living room is restricted is displayed, and as pattern B, the cooperation fee when the use of all home appliances in the living room is restricted is displayed. As a pattern C, it is possible to display a cooperation fee when the use of all home appliances in the living room and the room A is restricted. In this way, it is possible to set a restriction request regarding a plurality of patterns of target home appliances and the amount of remuneration, and to select home appliances to be used in accordance with the behavior of the householder. Furthermore, in FIG.8 and FIG.9, although the time of electric power suppression is 30 minutes, you may make it another length and a householder may select it.

  In addition, power suppression request information for requesting cooperation in power suppression at bedtime or when getting up may be generated and sent. At bedtime (when the family member presses the bed button), the amount of power consumption is reduced, so that it may be requested to use the bedtime time to cooperate in power suppression as when going out. When you wake up (when the resident presses the wake-up button), you may ask them to cooperate with power suppression by using only certain home appliances just like when you go home because the power consumption increases. .

  After generating and sending power suppression request information according to the change, the process returns to step 1 to check whether the power suppression period has ended. If not completed, the latest data is acquired and the power suppression amount is estimated. When estimating the power suppression amount, there is a possibility that a plurality of households that have received the suppression request information created in step 6 are responding to the suppression request, and the power suppression amount estimation value should increase.

In addition, as shown in FIGS. 6 to 9, if the family member is entrusted with a restraint request that includes the time he wants to cooperate in power restraint, it will limit what time it will go out, and what time it will limit the use of home appliances Therefore, it is possible to estimate with higher accuracy when estimating the power consumption by Equation (1).
If the power suppression time has expired in step 1, it is not necessary to estimate the power suppression amount or send power suppression request information any more, so the processing ends.

  In addition, the process of determining whether additional recruitment of the power suppression amount is necessary in steps 1 to 4 and the process of detecting the change of the power consumption pattern in steps 5 and 6 and generating and sending the suppression request information suitable for the change are performed in parallel You may make it carry out. That is, while it is determined that additional recruitment of power suppression is necessary in Steps 1 to 4, in order to increase the number of households that cooperate with the suppression request, changes in the power consumption pattern are always detected in Step 5 and Step 6. The power suppression request information suitable for the change may be continuously generated and sent.

Also, in this embodiment, power suppression request information is sent only to homes that have detected a change in power consumption pattern, but when it is determined that additional recruitment of power suppression is necessary, the current suppression request is entrusted. The power suppression request information may be sent to all households that are not. In this case, when it is first determined that additional recruitment for power suppression is required, the suppression request information is sent to all households that are not currently entrusted with the suppression request, and additional recruitment for power suppression is required thereafter. In this case, a change in the power consumption pattern is detected, and power suppression request information suitable for the change is created and sent only to the home. The method of power suppression when entrusted with a suppression request may be performed manually by a householder or remotely controlled by an aggregator. Further, the aggregator may be controlled remotely only for households that are entrusted with the suppression request and are absent.

  As described above, the power management system according to this embodiment has insufficient power suppression amount, and in addition, when a suppression request is issued to each household (customer), it is adapted to changes in the household power consumption pattern. Make a suppression request. Thereby, since the suppression request | requirement is issued according to each householder's action, the household which cooperates in electric power suppression increases, and it becomes possible to achieve the target electric power suppression amount more reliably. Also, by sending a request for suppression that includes the time you want to cooperate in power suppression, and having a family member entrust you with the request for suppression, the household will have low power consumption until what time (it will cooperate with power suppression) Therefore, the power consumption can be estimated with higher accuracy, and the target power suppression amount can be reliably achieved.

  In addition, since each household receives a suppression request when going out, it is possible to cooperate in power suppression using outing time or the like, and receive a suppression cooperation fee (incentive) without impairing comfort.

Embodiment 2. FIG.
FIG. 10 is a block configuration diagram of a power management system according to Embodiment 2 of the present invention.
The difference from the first embodiment is that a coupon generation unit 113 is added to the aggregator-side power management device 100 and a coupon display unit 206 is added to the home-side power management device 200.

  The coupon generation unit 113 of the aggregator-side power management apparatus 100 generates a discount coupon that prompts a home person to go out during the power suppression time or a discount coupon that prompts a person who goes out to increase the outing time. This discount coupon is a coupon that can be used in the vicinity of each household only during the power suppression time. The coupon generation unit 113 acquires whether or not it is necessary to send power suppression request information from the suppression request generation unit 112, and acquires the current power consumption pattern information of each home from the power consumption pattern information storage unit 110. . And the coupon production | generation part 113 sends the coupon suitable for a condition based on the power consumption pattern information (at home, going out) information of each household. The coupon generation unit 113 may acquire power consumption pattern information through the suppression request generation unit 112.

  The coupon display unit 206 of the home side power management apparatus 200 displays a discount coupon that can be used only during the power suppression time generated by the coupon generation unit 113 of the aggregator side power management apparatus 100. The contents to be displayed are discount contents, usable stores, time when coupons are valid, and the like. Discount coupons are displayed using a display or the like. In addition, when displaying, you may display on the same display as the display on which power suppression request information is displayed. Moreover, you may send to the terminal (cell phone, smart phone, tablet, etc. which a consumer owns) different from the home side power management apparatus 200 so that it can show immediately in a shop.

  Next, the flow of operation according to the power management system in this embodiment will be described. FIG. 11 is a flowchart showing the determination process for additional power suppression recruitment executed by the power management system according to the first embodiment of the present invention. In the following description, as in the first embodiment, the aggregator issues a power suppression request when a demand response is activated in advance (the day before, etc.), and each household has already responded to the suppression request as a consignment / rejection. An example will be described. Further, an example will be described in which the aggregator has already contracted with a power company or the like for a target power suppression amount when a demand response is activated. Moreover, the process (steps 1 to 6) from the start of the power suppression additional recruitment determination process to the generation and transmission of the suppression request suitable for the change is the same as in the first embodiment.

In the second embodiment, after the suppression request generation unit 112 detects the change in the power consumption pattern, generates the power suppression request information, and sends it, the coupon generation unit 113 is suitable for the change (in response to the change in the power consumption pattern). A combined coupon is created and sent (step 7). For example, if it is detected that the power consumption pattern has been changed from home to going out (a householder has pressed the go-out button), do not go home until the power suppression time is over, or the outing time will be a little longer Then, create and send a discount coupon to the home. The discount coupon to be created can be used during the power suppression time at supermarkets, restaurants, movie theaters, etc. around the home. In addition, the discount coupon to be created is not sent to all households connected to the aggregator, but is sent only to households whose power consumption pattern has been changed from home to going out. The discount effect may be increased.

After creating / sending the discount coupon, the process returns to step 1 in the same manner as in the first embodiment to check whether the power suppression period has ended. If not completed, the latest data is acquired and the power suppression amount is estimated. When estimating the power suppression amount, there is a possibility that a plurality of households that have received the suppression request created in step 6 are responding to the suppression request, and the power suppression amount estimation value should increase. Moreover, the discount coupon created in step 7 may be responding to a long-time suppression request, and the power suppression amount estimated value until the end of the power suppression time should increase.

In FIG. 11, the power consumption pattern change is detected (step 5), and after creating and sending a suppression request suitable for the change (step 6), a coupon suitable for the change is created and sent, but as shown in FIG. Alternatively, a coupon suitable for the power consumption pattern may be created and sent before step 5 (step 8).

FIG. 12 is a flowchart showing a case where a coupon is created / sent at a timing different from that in FIG. 11 in the power suppression additional recruitment determination process executed by the power management system according to the second embodiment of the present invention. In the case of FIG. 12, for example, a discount coupon that can be used during a power suppression time at a supermarket, a restaurant, a movie theater, or the like around the home for encouraging going out to a home whose power consumption pattern is at home. In addition, the discount coupon to be created is not sent to all the homes connected to the aggregator, but the power consumption pattern is sent only to homes at home, so the discount effect per coupon is high. It may be made to become.

After creating / sending the discount coupon, as in the first embodiment, the suppression request generation unit 112 detects the power consumption pattern change (step 5), generates power suppression request information suitable for the change, and each demand Send to home (step 6). When detecting this change in the power consumption pattern, the discount coupon created in step 8 may cause the householder who was scheduled to be at home to go out. Will be changed. This should increase the amount of power suppression.

  As described above, the power management system in this embodiment has a power suppression amount that is insufficient, and when an additional power suppression request is issued, a discount coupon according to the state or change of the power consumption pattern is sent, and the householder A power suppression request is made in accordance with changes in power consumption patterns (life patterns). For this reason, by sending discount coupons, it is possible to increase the number of families who plan to go out or to increase the number of family members who plan to stay home, so that more families can participate in longer time restraint requests. Therefore, it is possible to reliably achieve the target power suppression amount.

  Also, by sending a request for suppression that includes the time you want to cooperate in power suppression, and by having a family member entrust you with the power suppression request, the power consumption of the household will be low until what time. ), It is possible to estimate the power consumption with higher accuracy, and it is possible to reliably achieve the target power suppression amount.

  Also, instead of sending discount coupons to all households, coupons are sent only to specific households (customers), so the discount effect per coupon can be increased and more households Can participate in a longer time restraint request.

In addition, since each household receives a suppression request when going out, it is possible to cooperate in power suppression using outing time or the like, and receive a suppression cooperation fee (incentive) without impairing comfort. Furthermore, discount coupons that can be used around each home can be acquired.
