Description

The present invention relates to a technique for managing the electric power demand of a consumer, and more particularly to an electric power demand management device and a method for selecting and setting a consumer who is a target of a request for electric power suppression.

In order to avoid a situation where the power supply is insufficient when the power consumption temporarily rises and the power supply becomes tight due to the concentration of operations of the devices that consume power, etc. , The main body on the power supply side has proposed to make a demand control request (power consumption adjustment request) for adjusting the power consumption (see Patent Document 1). Hereinafter, as disclosed in Patent Document 1, changing the power consumption pattern so that the consumer side suppresses the use of electric power in response to a request from the electric power supply side is defined as a demand response.

Demand response (DR) is also beginning to be used by electric power companies as a normal means of securing capacity. Currently, each consumer is requested to control power saving for up to 3 hours, but if the power saving control of the building (customer) is not completed in the shortest possible time, it will lead to complaints from the residents of the building. It ends up. Therefore, in order to recruit more consumers, the demand response time zone requested by the electric power company is divided into multiple time zones, and the consumers of the power saving control request partner are switched for each divided time zone. A method called relay dispatch, in which power saving control is shared by the consumers, may be adopted.

FIG. 6 is a diagram illustrating an example of relay dispatch. Here, an example in which a power saving request is made to the consumer A, the consumer B, and the consumer C is shown. FIG. 7 (A) is a diagram showing an example of a relay dispatch setting set by an operator of an aggregator operator who adjusts power demand between an electric power company and a consumer, and FIG. 7 (B) is a diagram showing a reduction amount by time zone. It is a figure which shows one example. In the examples of FIGS. 7 (A) and 7 (B), the customer A is requested to save 200 kW of electricity during the time zones of 15:00 to 16:00 and 17:00 to 18:00, and the time is from 16:00 to 17:00. It can be seen that it is set to request the consumer B and the consumer C to save 100 kW of power during the time zone.

In the example of Patent Document 1, each consumer inputs the demand response schedule information for the future week and reports the schedule to the aggregator business operator. That is, the planned power reduction amount for each consumer is reported in advance for each time zone of each day.

On the other hand, a contract such as "up to 400 kW / day somewhere in a specific time zone during the day (for example, from 12:00 to 18:00)" may be concluded between the consumer and the aggregator operator. be. In this way, if the demand response time zone is only roughly defined and the detailed time zone setting is not specified in the contract, the aggregator operator individually sets the time zone for requesting power saving for multiple consumers. Although it is necessary, there is a risk that a setting error may occur because the setting work becomes complicated.

International release WO2016 / 186081

The present invention has been made to solve the above problems, and an object of the present invention is to provide a power demand management device and a method capable of reducing an error in relay dispatch setting.

The electric power demand management device of the present invention has a consumer information storage unit configured to store information of a plurality of consumers who are subject to a request for power suppression in advance, and a consumer selected by the user. A consumer is selected from the time zone setting unit configured to set the time zone as the scheduled power reduction time zone of the consumer and the information of the scheduled power reduction time zone of the consumer selected by the user. Based on the time zone display unit configured to be displayed in the first display area of the setting screen and the information stored in the customer information storage unit, the power reduction schedule of the customer selected by the user is planned. Information on the total amount of the planned power reduction amount set by all the consumers and the planned power reduction amount setting unit configured to set the amount for each scheduled power reduction time zone is described for each scheduled power reduction time zone. It is displayed in the second display area of the setting screen, and when the planned power reduction amount is newly set by the planned reduction amount setting unit, the total of the planned power reduction amount in the corresponding scheduled power reduction time zone is newly set. Based on the planned reduction amount display unit configured to update the display of the second display area so as to increase by the amount of the planned power reduction amount, and the information stored in the customer information storage unit. When it is determined that the planned power reduction time zone cannot be set , the customer information is provided with a setting prohibition unit configured to prohibit the setting of the planned power reduction time zone and the planned power reduction amount. The storage unit stores at least information on the maximum daily power reduction possible amount and the power reduction possible amount per unit time of each consumer, and the reduction planned amount setting unit is before setting the power reduction planned amount. Based on the information stored in the consumer information storage unit, the power reduction provisional amount of the consumer selected by the user is calculated for each time zone selected by the user, and the setting prohibition unit is used. The value obtained by adding the provisional power reduction amount calculated by the planned power reduction amount setting unit to the sum of the planned power reduction amounts set by the customer selected by the user is the maximum daily power consumption of this customer. When the amount that can be reduced is exceeded, it is determined that the planned power reduction time zone cannot be set, and the planned power reduction amount setting unit determines the provisional power reduction amount when the planned power reduction time zone can be set. Is set as the planned power reduction amount of the consumer selected by the user .
Further, in one configuration example of the power demand management device of the present invention, the planned reduction amount display unit displays information on the required power reduction amount determined in advance on top of the information on the total sum of the planned power reduction amounts. It is characterized by that.

In the planned reduction amount display unit, the horizontal axis is common to the time axis of the first display area, and the vertical axis is power. It is characterized in that it is displayed in the second display area for each scheduled time zone.

In addition, the power demand management method of the present invention displays information on the set scheduled power reduction time zones of a plurality of consumers who are the targets of the power suppression request in the first display area of the setting screen for selecting the customer. The first step, the second step of displaying the total information of the set planned power reduction amounts of all consumers in the second display area of the setting screen for each scheduled power reduction time zone, and the user. When the third step of setting the selected time zone of the consumer selected by the customer as the scheduled power reduction time zone of this consumer and the new scheduled power reduction time zone set by this third step Refer to the fourth step of updating the display of the first display area and the customer information storage unit that stores the information of each customer in advance, and based on the information stored in the customer information storage unit. In addition, the fifth step of setting the planned power reduction amount of the consumer selected by the user for each scheduled power reduction time zone, and when the planned power reduction amount is newly set by this fifth step. , The sixth step of updating the display of the second display area so that the total sum of the planned power reduction amounts in the corresponding scheduled power reduction time zone is increased by the newly set planned power reduction amount, and the demand. When it is determined that the planned power reduction time zone cannot be set based on the information stored in the house information storage unit, the setting of the planned power reduction time zone and the planned power reduction amount is prohibited. The consumer information storage unit stores at least information on the maximum daily power reduction possible amount and the power reduction possible amount per unit time of each customer, and the fifth step is , The power reduction provisional amount of the consumer selected by the user is determined for each time zone selected by the user based on the information stored in the customer information storage unit before the setting of the planned power reduction amount. In the seventh step, the power reduction provisional amount calculated in the fifth step is added to the total set power reduction planned amount of the consumer selected by the user. The fifth step includes the step of determining that the planned power reduction time zone cannot be set when the value exceeds the maximum daily power reduction possible amount of the consumer, and the fifth step is the power reduction schedule. It is characterized by including a step of setting the power reduction provisional amount as a planned power reduction amount of a consumer selected by the user when a time zone can be set .

According to the present invention, it is possible to shorten the power suppression time of each consumer and schedule it, and by providing a setting screen in which the setting operation and the confirmation of the operation result can be visually performed, the error of the relay dispatch setting can be reduced.

Hereinafter, examples of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a power demand management device according to an embodiment of the present invention. The electric power demand management device 1 includes a consumer information storage unit 2, a time zone display unit 3, a reduction schedule amount display unit 4, a time zone setting unit 5, a setting storage unit 6, and a reduction schedule amount setting unit 7. The setting prohibition unit 8, the setting prohibition display unit 9, the request input unit 10, the power saving request unit 11, the display device 12, and the input device 13 are provided. The electric power demand management device 1 is installed in, for example, a management center of an aggregator operator.

FIG. 2 is a flowchart illustrating the operation of the power demand management device 1 of this embodiment when the relay dispatch is set.
The consumer information storage unit 2 contains information on the maximum power reduction amount ERmax per day, information on the power reduction amount ERt per unit time (1 hour), and information on the power reduction time zone. It is stored in advance for each consumer managed by the aggregator operator. For example, suppose that customer A has a contract that "a maximum of XXX [kW / day] can be reduced somewhere in a specific time zone during the day (for example, from 12:00 to 18:00)". Assuming that consumer A can reduce YYY [kW] per hour, it is possible to reduce ERmax / ERt = XXX / YYY [hours] somewhere between 12:00 and 18:00. It turns out that.

When the relay dispatch is set, the time zone display unit 3 of the power demand management device 1 displays the first display area 121 indicating the set scheduled power reduction time zone of each consumer on the relay dispatch setting screen 120 of the display device 12. FIG. Is displayed (step S1 in FIG. 2). In the first display area 121, the set scheduled power reduction time zone for each customer is displayed along the time axis. Specifically, a square 122 representing a time zone in units of 30 minutes is displayed for each customer. Here, since the scheduled power reduction time zone for each customer is not set, all the squares 122 are white backgrounds indicating that they have not been set.

The planned power reduction time in this embodiment indicates the elapsed time from the start of power suppression. The reason why the scheduled power reduction time is the elapsed time from the start of suppression is that the relay dispatch setting of this embodiment is a setting work in which a consumer is selected in advance before the start of power suppression. .. The duration of power restraint is decided in advance by contract, but when the power company requests power restraint is determined by the supply and demand balance of the power company on the day. Therefore, the user (operator) who sets the relay dispatch cannot know in advance when the power company requests the power suppression. As described above, the scheduled power reduction time (from 0:00 to 3:00 in the example of FIG. 3) in this embodiment indicates the elapsed time from the start of power suppression. In the example of FIG. 3, the screen shows the schedule for 3 hours from the start of power suppression, but it goes without saying that the schedule for 3 hours or more may be set.

On the other hand, the planned reduction amount display unit 4 of the power demand management device 1 graphically shows the total of the set planned power reduction amounts of all consumers for each time zone (for each elapsed time zone from the start of power suppression). The second display area 123 is displayed on the relay dispatch setting screen 120 of the display device 12 as shown in FIG. 3 (step S2 in FIG. 2). In this graph, the horizontal axis is common to the time axis of the first display area 121, and the vertical axis is electric power. Further, the planned reduction amount display unit 4 displays the required power reduction amount NER by a line 124 (for example, a red line) so as to be superimposed on the graph of the second display area 123 (step S2). This required power reduction amount NER is predetermined, for example, at the request of the power company. In the example of FIG. 3, the planned power reduction amount of each consumer is not set, and the total sum of the planned power reduction amounts is 0 in each time zone.

The user (operator) of the power demand management device 1 operates an input device 13 such as a mouse to perform relay dispatch among the squares 122 of the time zone displayed in the first display area 121 of the relay dispatch setting screen 120. Click the grid 122 of the desired time zone of the customer you want to set.

When the selection operation by the input device 13 as described above is performed by the power demand management device 1 in the planned reduction amount setting unit 7 (YES in step S3 of FIG. 2), the unit time (1 hour) of the consumer selected by the user. ) The information of the power reduction possible amount ERt per is acquired from the consumer information storage unit 2, and based on this power reduction possible amount ERt, the power reduction provisional amount of the customer is estimated for each time zone selected by the user. Calculate (step S4 in FIG. 2).

In the above example, the scheduled power reduction time zone can be set in units of 30 minutes, so if the time zone from 0:00 to 0:30 and the time zone from 0:30 to 1:00 are selected by the user, these The power reduction provisional amount in the time zone of 30 minutes is ERt / 2.

The setting prohibition unit 8 of the power demand management device 1 determines whether or not the scheduled power reduction time zone can be set when the selection operation by the input device 13 as described above is performed (YES in step S3) (YES in step S3). FIG. 2 Step S5). Specifically, the setting prohibition unit 8 acquires information on the maximum daily power reduction possible amount ERmax of the customer selected by the user from the customer information storage unit 2, and has already set the customer. The information of the planned power reduction amount SER is acquired from the setting storage unit 6, and the power reduction provisional amount calculated by the planned power reduction amount setting unit 7 is added to the total of the set power reduction planned amount SER of the customer. If the value is equal to or less than the power reduction possible amount ERmax of the consumer, it is judged that the power reduction scheduled time zone can be set.

When it is determined that the scheduled power reduction time zone can be set (YES in step S5), the time zone setting unit 5 of the power demand management device 1 sets the time zone selected by the consumer selected by the user. It is set as the scheduled power reduction time zone for consumers (step S6 in FIG. 2). Information on the selected consumer and the scheduled power reduction time zone is stored in the setting storage unit 6.

When the scheduled power reduction time zone is set in step S6, the time zone display unit 3 of the power demand management device 1 updates the first display area 121 (FIG. 2, step S7). Specifically, the time zone display unit 3 changes the display color of the grid 122 corresponding to the scheduled power reduction time zone of the consumer selected by the user, thereby changing the scheduled power reduction time of the selected consumer. Notify the user that the band setting is complete.

Next, when it is determined that the planned power reduction amount setting unit 7 of the power demand management device 1 can set the planned power reduction time zone (YES in step S5), the user performs the power reduction provisional amount calculated in step S4. It is determined as the planned power reduction amount SER in the planned power reduction time zone of the consumer selected by (FIG. 2, step S8). The information of the planned power reduction amount SER is stored in the setting storage unit 6.

When the planned power reduction amount SER is determined in step S8, the planned reduction amount display unit 4 of the power demand management device 1 updates the second display area 123 (step S9 in FIG. 2). Specifically, in the planned power reduction amount display unit 4, the sum of the planned power reduction amounts of all the consumers in the planned power reduction time zone set in step S6 is the total power reduction planned amount SER determined in step S8. The graph of the second display area 123 is updated so as to increase by the amount.

FIG. 4 shows an example of the relay dispatch setting screen 120 after the first display area 121 and the second display area 123 have been updated. In the example of FIG. 4, the time zone from 0:00 to 0:30 and 0:30 to 1:00 for customer A, and from 1:00 to 1:30 and 1:30 to 2:00 and 2:00 for customer B. Since the time zone from 2:30 to 2:30 and the time zone from 2:30 to 3:00 of customer C are set as the scheduled power reduction time zones, the display of the corresponding squares 122 in the first display area 121 is displayed. As the colors are changed, the graph 125 is updated so that the total of the planned power reduction amounts in these scheduled power reduction time zones is increased by the amount of the planned power reduction amount SER determined in step S7.

In this way, while looking at the relay dispatch setting screen 120, the user is requested to suppress the power so that the sum of the planned power reduction amounts in each time zone in 30-minute units is equal to or more than the required power reduction amount NER. You can repeatedly select the house and the scheduled power reduction time zone.

Next, the setting prohibition unit 8 of the electric power demand management device 1 sets the electric power of the consumer selected by the user when the selection operation by the input device 13 as described above is performed (YES in step S3). If the value obtained by adding the provisional power reduction amount calculated by the planned power reduction amount setting unit 7 to the sum of the planned power reduction amount SER exceeds the power reduction possible amount ERmax of the customer, the planned power reduction time zone cannot be set. It is determined that it is possible (NO in step S5), and the time zone setting unit 5 is notified that the scheduled power reduction time zone cannot be set (FIG. 2, step S10).

When it is determined that the scheduled power reduction time zone cannot be set, the setting prohibition display unit 9 of the power demand management device 1 relays a message or the like notifying the user that the scheduled power reduction time zone cannot be set. It is displayed on the dispatch setting screen 120 (step S11 in FIG. 2). In this way, when it is determined that the planned power reduction time zone cannot be set, the setting of the planned power reduction time zone and the planned power reduction amount SER is prohibited, and the process returns to step S3.
The power demand management device 1 performs the above operations until the user completes the relay dispatch setting (YES in step S12 of FIG. 2).

After the relay dispatch setting as described above, when the request input unit 10 of the power demand management device 1 receives the request for power suppression from the power company, the power saving request unit 11 of the power demand management device 1 receives the request from the power company. Contents and settings Based on the contents of the relay dispatch setting stored in the storage unit 6, the contents of the request for power suppression to the consumer are determined, and the determined contents are notified to the consumer. The request for power suppression from the electric power company and the request for power suppression to the consumer include, for example, the contents such as the power suppression start time, the power suppression duration, and the amount of power reduction.

In addition, in order to determine the content of the request for power reduction to the consumer, the scheduled power reduction time for each customer preset in the relay dispatch setting is converted to the time of the actual day, and the power reduction is performed. It is necessary to create a schedule, and such a schedule may be created automatically by the power saving requesting unit 11 or manually by the operator.

In this way, in this embodiment, the relay dispatch setting screen 120 can be scheduled to shorten the power suppression time of each consumer while maintaining the required power reduction amount NER, and the setting operation and the operation result can be visually confirmed. By providing it, it is possible to reduce errors in relay dispatch settings.
