Description

  The present invention relates to an electric energy control operation planning system, and more particularly, to reduce power costs in accordance with an operation plan of a facility of a water utility that is a consumer of electric power, and to smooth a peak load and / or charge system. TECHNICAL FIELD The present invention relates to an electric energy control operation planning device that enables electric energy control conforming to, and a water supply system including the same.

Conventionally, facility equipment of electric power consumers is operated by schedule control or automatic control according to demand fluctuations based on a daily operation plan. The amount of power used is determined in accordance with the operation of the device, but the peak time zone of the demand amount overlaps with other power consumers in a similar time zone. For the power supply side, in order to survive this peak time, measures to reduce the peak have been introduced in order to secure the supply amount. As a measure, in the power contract by season, in the summer and other seasons, peak hours from 1 pm to 4 pm on weekdays in summer, daytime hours from 8 am to 10 pm on weekdays, peak hours and daytime It aims to reduce the peak by combining night time other than time. In addition, there is a demand response in which the power consumer changes the demand amount to match the power supply-demand balance, and the power consumer trades with the power company or aggregator.
For example, in Patent Literature 1, the desired operation end time of the home appliance input by the user, the operation period information indicating the period required for the operation of the home appliance, and the power information indicating the power required for the operation of the home appliance are controlled by the device control. The device receives it. And the operation time calculation part which comprises an apparatus control apparatus is the time shift set by the time shift period setting part based on each received said information and the electricity bill information provided from an electric power company (electric power supplier). Within the period, the operation start time at which the power charge charged when the home appliance is operated is less than or equal to the predetermined charge (the power charge is the cheapest) is calculated, and the operation of the home appliance is started at the operation start time. A configuration is disclosed.
Moreover, in patent document 2, in order to control the power consumption of several information processing apparatus, the performance power consumption of each information processing apparatus is measured, and each information processing apparatus is made to achieve the target power consumption of the whole system. It is disclosed that time allocation is set and operation of the information processing apparatus is controlled.

However, in the configuration of Patent Document 1, although the operation start time at which the power charge required for driving is reduced is calculated based on the operation period (time required for driving) of the home appliances, these home appliances are operated individually. It is a premise, and no consideration is given to the situation where a plurality of electric devices are operated in conjunction with each other. Therefore, even when a plurality of electrical devices are to be operated at the same time, it may occur that they are operated alone. Therefore, there is a possibility that the target operating condition cannot be satisfied.
Moreover, in the configuration of Patent Document 2, although the target power consumption of the entire system is distributed to each information processing device that constitutes the system, each information processing device is operated independently, The information processing apparatus does not cooperate. That is, in allocating the target power consumption, no consideration is given to application to a system in which a plurality of information processing apparatuses operate in conjunction with each other.
Equipment that can be operated independently is mixed with equipment that can be operated by a water utility that is an electric power consumer, and equipment that is operated in conjunction with a plurality of equipment. Therefore, as in Patent Document 1 and Patent Document 2 described above, in the power control operation plan that considers only reducing the amount of power, it is difficult to effectively reduce power because it is not possible to incorporate equipment with interlocking conditions as control targets. It becomes.
Therefore, the present invention increases the number of electric devices to be reduced in electric power, so that it can control not only electric devices that can be operated independently but also electric devices that operate in conjunction with each other, and a water supply provided with the same. To provide a system.

In this specification, “electric power consumer” refers to a water utility that concludes a demand response contract with an aggregator that is an electric power company or electric power operator, and “water consumer” refers to a water utility owned by a water utility. The case where it is an individual using the tap water (tap water) supplied by the facility is taken as an example.
FIG. 1 is an overall schematic configuration diagram including a water supply system and a power supply system including a power amount control operation planning device in a water supply facility of a water supply company according to an embodiment of the present invention.
As shown in FIG. 1, raw water that becomes tap water, for example, is taken from a river (water source) 3 by a water intake pump 4 of a water intake plant 5 and is sent to a water purification plant 7 by a water transfer pump 6. In the water purification plant 7, filtration treatment, coagulation sedimentation treatment, and / or chlorine sterilization treatment are performed. Water that conforms to the water quality standards is sent as tap water to the A distributing reservoir 9a and the B distributing reservoir 9b by the water supply pumps 8a and 8b, respectively. Furthermore, the tap water stored in the A distribution reservoir 9a and the B distribution reservoir 9b is supplied to the water consumers 12 in each distribution area via the distribution pipe network 11 by the distribution pumps 10a and 10b.

  Since various electric devices of the water purification plant 7 which is a water supply facility, the intake pump 4, the water transfer pump 6, the water pumps 8a and 8b, the water distribution pumps 10a and 10b, etc. consume a large amount of power, the amount of power used by water facilities nationwide Accounts for about 0.8% of Japan's total electricity consumption. Among them, about 80% is consumed by pumps such as the intake pump 4, the water transfer pump 6, the water pumps 8a and 8b, and the water distribution pumps 10a and 10b. For this reason, it is particularly important for a water utility, who is also a power consumer who owns and operates a water supply facility, to reduce the amount of power used by efficiently operating these devices.

A water supply system 100 according to an embodiment of the present invention includes a water intake pump 4, a water pump 6, water pumps 8a and 8b, and water pumps 10a and 10b, a water intake 5, a water purification plant 7, and a water distribution reservoir. 9a, B distribution reservoir 9b, distribution pipe network 11, supervisory control device 2 that performs water supply plan planning and monitoring control of equipment in water facilities such as the above-mentioned various pumps in consideration of the balance between supply and demand of tap water, and electric energy control An operation planning device 1 is provided. In addition, a terminal device 15 is connected to the electric energy control operation planning device 1 and the monitoring control device 2 for the operator to set operating conditions of various devices. In this specification, the terminal device 15 and the power amount control operation planning device 1 may be referred to. The monitoring control device 2 is electrically connected to the above-described various pumps and the water purification plant 7 via the communication network 13 or the communication line.
The water purification plant 7 and the A distributing reservoir 9a, and the water purification plant 7 and the B distributing reservoir 9b are communicated with each other through a water pipe. In addition, the A distributing reservoir 9a and the distributing pipeline network 11 and the B distributing reservoir 9b and the distributing pipeline network 11 are communicated with each other by distributing pipelines. FIG. 1 shows a mode in which water is supplied from the A distribution reservoir 9a and the B distribution reservoir 9b to the distribution pipeline network 11 through distribution pipelines by the distribution pumps 10a and 10b. However, the present invention is not limited to this, and a branch pipe is provided in the middle of the water supply pipe from the water purification plant 7 to the A distribution reservoir 9a and the B distribution reservoir 9b, and the distribution pipeline is not provided through the A distribution reservoir 9a and the B distribution reservoir 9b. In some cases, water is supplied to the water consumer 12 via the network 11. In this case, the water supply pumps 8a and 8b for supplying water from the water purification plant 7 to the A distribution reservoir 9a and the B distribution reservoir 9b are referred to as distribution pumps. Moreover, in FIG. 1, although the example which has two water supply reservoirs 9a and 9b, two water supply pumps 8a and 8b, and water supply pumps 10a and 10b is shown for convenience of explanation, these numbers are not restricted to two. .

The power amount control operation planning device 1 is electrically connected to the monitoring control device 2 and is also connected to the aggregator 16 through the communication control device 14 and the communication line network 13. The aggregator 16 is connected to the power supply system 17 through the communication network 13.
For example, a demand response command for power reduction during peak hours in summer is transmitted from the power supply system 17 of the power company via the aggregator 16 and the communication control device 14 connected to the communication line network 13. Sent to the device 1. Here, the “demand response command” is, for example, received by the electric energy control operation planning device 1 as the “peak cut command”, and the peak cut command includes the target peak time zone and the power used. The amount of reduction is included. As a response to this peak cut command, for example, by setting any pump out of a plurality of pumps scheduled to be operated during the peak time period among the operation time periods assigned to the various pumps described above, Reduce the instructed power consumption. Alternatively, by moving (time-shifting) the operation time zone of an arbitrary pump among the plurality of pumps scheduled to be operated during the peak time zone, as a result, the amount of power used in the instructed peak time zone is reduced. .

  Below, the Example of the electric energy control operation | use plan apparatus 1 which comprises the water supply system of this invention is described in detail using drawing.

FIG. 2 is a functional block diagram of the electric energy control operation planning device 1 according to the first embodiment of the present invention. As shown in FIG. 2, the power amount control operation planning apparatus 1 includes a power usage amount collection unit 18, a water operation plan data collection unit 19, a time series data processing unit 20, an operation plan generation unit 27, and an operation plan generation unit 27. The operation plan correction processing unit 28 for correcting the generated operation plan, the control command output unit 34 for outputting the operation plan corrected by the operation plan correction processing unit 28 to the monitoring control device 2, the aggregator 16 and the communication network 13 The communication processing unit 30 enables communication via the communication processing unit 30 (not shown in FIG. 2), and the demand response processing unit 29 receives and processes a demand response command transmitted from the aggregator 16 via the communication processing unit 30.
Moreover, the electric energy control operation planning device 1 includes an interlock operation interlock setting unit 31, a demand response target device setting unit 32, and an hourly charge setting unit 33. The operation plan generation unit 27, the operation plan correction processing unit 28, the demand response processing unit 29, the interlock operation interlock setting unit 31, the demand response target device setting unit 32, the hourly charge setting unit 33, and the control command output unit 34 are, for example, Realized in software. Specifically, a processor such as a CPU (not shown), a ROM for storing various programs, a RAM for temporarily storing calculation process data of various programs read from the ROM by the processor, an external storage device, or the like Hardware is configured by the memory.

In addition, the electric energy control operation planning device 1 includes an electric energy time-series data file unit 21, a water operation plan data file unit 22, a device-specific rated power value file unit 23, an interlock operation interlock file unit 24, and a demand response compatible device file. A database or storage unit such as the unit 25 and the hourly fee file unit 26 is provided.
The power usage amount collecting unit 18 collectively acquires the power usage amount measurement information indicating the operation state of each device in the water supply facility from the monitoring control device 2. The power usage amount of each device captured by the power usage amount collecting unit 18 is stored in the power amount time-series data file unit 21 by the time-series data processing unit 20. The rated power consumption during operation of each device in the water supply facility is stored in advance in the device-specific rated power value file unit 23.

  The monitoring and control device 2 creates an optimal water operation plan for daily water demand fluctuations. Usually, the next day's water demand is predicted on the previous day, an operation plan for each device in the water supply facility is made, and each device is operated and controlled according to the operation plan. The amount of water demand varies from moment to moment depending on the weather of the day and the behavior of the water customer 12 (FIG. 1). Therefore, the water operation plan is finely corrected based on the actual data so that it can follow the amount of change in water demand, and actual operation starts. The water operation plan data created by the monitoring control device 2 is input to the water operation plan data collection unit 19. The input water operation plan data is stored in the water operation plan data file unit 22 by the time-series data processing unit 20.

  In FIG. 3, the example of the driving | running state (operation schedule) of the main equipment in a water supply facility is shown. As shown in FIG. 3, each facility, that is, a water intake station 5, a water pumping station, a water purification plant 7, an A distributing reservoir 9 a, and a B distributing reservoir 9 b, each has a plurality of intake pumps 4 as shown in the equipment name column. The water transfer pump 6, the water pumps (8a, 8b), and the water distribution pumps (10a, 10b) are installed. For each of these pumps, the rated power value stored in the device-specific rated power value file unit 23 is shown in the rated output (kW) column in advance. In the right column, as an example, the operation time period from the operation start time to the operation end time of each pump at the time from 0:00 am to 9:00 am is shown. In the operation time zone for each pump, the operation plan generation unit 27 reads out the water operation plan data stored in the water operation plan data file unit 22, and the operation start time specified in the read water operation plan data. And based on the operation end time.

In the example shown in FIG. 3, a case where a water utility that owns and operates the water supply system 100 shown in FIG. 1 has concluded a contract of 1400 kW with a power company (including aggregator 16), for example, 1400 kW. Show. As shown at the bottom of FIG. 3, the predicted power usage from midnight to 9 am is shown as time series data. Here, the predicted power consumption at each time is obtained as follows. First, the operation plan production | generation part 27 extracts the pump which is an operating device of an operation time slot | zone at each time. Subsequently, the operation plan generation unit 27 extracts the extracted rated power value of the pump by referring to the device-specific rated power value file unit 23. By calculating the extracted rated power values of the pumps, the predicted power usage at each time is obtained.
In FIG. 3, for example, at time 3:50, No. 2 intake pump (rated power value 80 kW) and No. 3 intake pump (rated power value 100 kW) installed in intake water station 5, 1 installed in water pump station No.1 water pump (rated power value 250 kW), No.4 water pump (rated power value 300 kW), No.1 water pump installed in the water purification plant 7 (rated power value 120 kW), No.1 water distribution installed in the A reservoir 9a The pump (rated power value 50 kW) and the No. 1 water pump (rated power value 30 kW) and No. 2 water pump (rated power value 30 kW) installed in the B reservoir 9b are in the operation time zone. Therefore, the operation plan production | generation part 27 calculates the estimated electric power consumption in time 3:50 as 960 kW by totaling the rated electric power value of these pumps. The same applies to other times.

FIG. 4 shows an example of the operation status when the linked operation is set as the operation condition of the main equipment in the water supply facility. As shown in FIG. 4, in comparison with FIG. 3, an operating condition in which a plurality of operating devices (pumps) are linked and operated between a “device name” and a “rated power (kW)” column indicating the rated power value of each pump. Alternatively, a “Linked Interlock” column is newly provided that allows specification of operating conditions for independent operation. In this “interlocking interlock” column, a pull-down button is provided to enable easy setting of interlocking operation interlock setting (◯ mark) and interlocking operation interlock non-setting (× mark). The interlock operation interlock setting on the screen will be described later. Here, interlocked operation interlock is a device that can be selected on the display screen all at once for interlocked operation, but prevents operation from being set erroneously so that it cannot be selected alone. is there.
As shown in FIG. 4, for example, the No. 1 water distribution pump and the No. 2 water distribution pump installed in the A distribution reservoir 9 a indicate that they are in interlocking operation conditions. Similarly, the No. 1 water pump and No. 2 water pump installed at the water purification plant 7 are in linked operation conditions, and further, the No. 1 distribution pump installed in the B water reservoir 9b is operated in conjunction with the No. 3 water pump. Indicates that the condition is met. A contract is usually concluded between the power company and a water company that owns and operates the water system 100 so that the contract power does not exceed the peak power amount throughout the year. The monthly power charge is the sum of the basic charge determined by the contract power and the power charge according to the power usage. Therefore, in order to reduce the power charge, it is also an effective method to smooth the peak load as much as possible and lower the contract power. In order to lower the contract power 1 (P1: 1400 kW) in FIG. 4 to the contract power 2 (P2: 1100 kW), the operation method is changed so that the operation of the device in the time zone in which the peak load occurs is moved to another time zone. There is a need. That is, in order to lower the peak power, the operation plan correction unit 28 selects a device that can be moved in another time zone on the screen displaying the operation status in FIG. 4 and changes the operation start time and the operation end time. Based on the change result, the operation plan generation unit 27 recalculates the predicted power usage, and verifies whether the predicted power usage falls within the range of contract power 2 (P2) lower than the contract power 1 (P1). .

Here, the rated power value of each pump will be described. In the example shown in FIG. 4, the relationship between the rated power values of the pumps is as follows.
Water transfer pump 6> Water pumps 8a, 8b> Water intake pump 4> Water pumps 10a, 10b
However, if the elevation of the distribution pipe network 11 laid by the distribution pumps 10a and 10b, that is, the distribution area is higher than that of the A distribution tank 9a and the B distribution tank 9b, the distribution pumps 10a and 10b are used. The discharge pressure increases, and the rated power values of the water distribution pumps 10a and 10b used also increase. This is the same in the water pumps 8a and 8b, and when the water purification plant 7 is provided at a higher elevation than the A reservoir 9a and the B reservoir 9b, water can be sent by natural flow. Water pumps 8a and 8b having a low discharge pressure can be used. On the other hand, when the A distributing reservoir 9a and the B distributing reservoir 9b are located at an altitude higher than the water purification plant 7, natural flow cannot be used, and the water pumps 8a and 8b to be used have high rated power values.

FIG. 5 is a display example of the terminal display screen when the linked operation shown in FIG. 4 is set. As shown in FIG. 5, the terminal display screen 150 of the terminal device 15 connected to the electric energy control operation planning device 1 includes a first display area 151, a second display area 152, a setting button 153, a time shift button 154, and It consists of an execution button 155. In the first display area 151, a diagram showing an example of an operation situation in which the linked operation is set as the operation condition of the main equipment in the water facility shown in FIG. 4 is displayed. The second display area 152 includes the facilities and operating devices displayed in the first display area 151, and a schematic diagram from the river 3 as a water source to the water distribution areas (water distribution area A and water distribution area B) is a system diagram. Displayed as a diagram. The operator checks the system diagram displayed in the second display area 152 and sets the interlock operation interlock for each device such as the intake pump displayed in the first display area 151 using the pull-down button. I do. Thereafter, when the setting button 153 is designated, the interlock operation interlock setting unit 31 (FIG. 2) stores the interlock operation interlock setting content displayed in the first display area 151 in the interlock operation interlock file unit 24. To do. Here, the data structure of the operation interlock setting status of the interlock operation device stored in the interlock operation interlock file unit 24 is shown in FIG. As shown in FIG. 6, for each device installed in each facility, either linked operation interlock setting (◯ mark) or linked operation interlock non-set (x mark) is stored. Thus, since the interlock operation interlock can be set in the first display area 151 while confirming the system diagram displayed in the second display area 152, for example, a plurality of water distribution pumps installed in the same reservoir Of these, the convenience can be improved when the operator determines whether or not the specific water distribution pump should be operated in conjunction.
In FIG. 5, the elevation data may be combined and displayed in the system diagram displayed in the second display area 152. Further, the second display area 152 may be a multi-window method, and detailed information of the area in the system diagram that is appropriately designated by the operator may be displayed in a pop-up on a new window.

  FIG. 7 is a diagram showing an operation status when the operation time zone of a specific device is moved (time shift) and controlled so as not to exceed the contract power, and is displayed in the first display area 151 shown in FIG. Only the contents to be processed are shown. First, in the time series data of the predicted power consumption displayed in the first display area 151 of FIG. 5 described above, the time period from 6 am to 9 am exceeds the contract power 2 (P2: 1100 kW). ing. In this state, when the operator specifies the time shift button 154 to avoid exceeding the contract power 2 (P2), the desired device (pump) displayed in the first display area shown in FIG. It will be in the state where movement time, ie, a time shift, is possible. In the example shown in FIG. 7, the minutes from No. 3 to No. 6 am, which is the operating time zone of No. 3 intake pump installed in intake No. 5, is changed from No. 2 to No. 3 am, and water is introduced. The minutes from 7:00 am to 9:00 am, which is the operating time zone of No. 4 water pump at the pump station, has been changed from 2:00 am to 3:50 am. This movement of the operation time zone is a state in which the operator designates the operation time zone of the desired device (pump) with the cursor by an input device such as a mass of the terminal device 15 and the desired operation time zone is selected and designated. This is done by dragging with a mouse or the like. After that, when the execution button 155 shown in FIG. 5 is designated by the operator, the operation plan correction processing unit 28 outputs the operation state (operation schedule) after the time shift shown in FIG. The operation plan generation unit 27 refers to the device-specific rated power value file unit 23 as described above, and recalculates the predicted power usage. Then, the time series data of the predicted power usage after recalculation is displayed in the first display area 151 as shown in FIG. By this movement (time shift) of the operation time zone, the predicted power usage is corrected to an operation plan that does not exceed the contract power 2 (P2) in the time zone from 0 am to 9 am. The corrected operation plan is output to the monitoring control device 2 via the operation plan correction unit 28 and the control command output unit 34. As described above, the operator can check the system diagram displayed in the second display area 152 even when the operation time zone is moved (time shift). Therefore, in determining the combination of pumps that should be moved in the operation time zone. Convenience can be improved.

In FIG. 7, the linked operation is not set as the operating condition, that is, the operation time zone of the No. 3 intake pump and the No. 4 water pump in which the independent operation is set as the operating condition is moved (time shifted). Although shown, it is not limited to this. For example, even for a combination of a plurality of pumps for which linked operation is set as an operation condition, the operation time zone can be moved (time shift) in units of these combinations. However, in this case as well, it is desirable to set a higher priority for a combination of independently operable pumps for which no linked operation condition is set, as candidate movement candidates (time shift candidates) in the operation time period.
Moreover, the influence on the water customer 12 by the movement (time shift) of the operation time zone of the pump specified and specified can be prevented by the water purification plant 7 or the water reservoirs (9a, 9b) serving as a buffer. The relationship between the capacity of the water purification plant 7 or the distribution reservoir (9a, 9b), for example, the monitoring of the water level in the settling basin in the water purification plant 7 and the water level in the distribution reservoir (9a, 9b) is performed by the monitoring control device 2. .

In FIG. 8, the operation | movement flowchart of the electric energy control operation planning apparatus 1 is shown. The power control and operation planning device 1 displays a system diagram of the water supply facility in the second display area 152 of the terminal display screen 150, and displays the operation conditions and operation status of each device in the first display area 151 (step S101). ). Here, the operation status of each device is determined by the operation plan generation unit 27 based on the water operation plan data collected and stored from the monitoring control device 2 with reference to the water operation plan data file unit 22. The interlocking operation interlock setting unit 31 receives the interlocking operation interlock setting for each water facility device input by the operator via the first display area 151 (step S102).
In step S <b> 103, the linked operation interlock setting unit 31 stores the received linked operation interlock setting status for each device in the linked operation interlock file unit 24. The operation plan correction processing unit 28 monitors whether or not an instruction is input to the time shift button 154 in the terminal display screen 150. If there is no instruction input to the time shift button 154, the operation plan correction processing unit 28 enters a standby state and ends the process. On the other hand, if an instruction input to the time shift button 154 is detected, the process proceeds to step S105.

In step S105, when the operation plan correction processing unit 28 detects an instruction input to the execution button 155 in the terminal display screen 150, the operation plan generation unit displays the operation status (operation schedule) after the operation time zone shift (time shift).

  FIG. 9 is a diagram illustrating a setting example of a demand response target device stored in the demand response compatible device file part of the power amount control operation planning apparatus according to the second embodiment of the present invention. The present embodiment is different from the first embodiment in that in addition to the interlock operation interlock setting function shown in the first embodiment, a function capable of responding to a demand response command from an electric power company is provided. The overall configuration of the water system 100 shown in FIGS. 1 and 2 and the functional block configuration of the power amount control operation planning device are the same as those in the first embodiment. Below, the description which overlaps with Example 1 is abbreviate | omitted.

  First, as shown in FIG. 1, the demand response command from the power supply system 17 of the electric power company is a power consumer who has concluded a demand response contract via an aggregator 16 which has previously concluded a demand response contract with the target consumer. Is received via the communication line network 13 by the electric energy control operation planning device 1 constituting the water system 100, which is owned and operated by the water company. Specifically, the demand response command from the aggregator 16 is received by the communication processing unit 30 shown in FIG. 2 and input to the demand response processing unit 29. In response to the demand response command, the demand response processing unit 29 is set in advance as a demand response compatible device among the operation devices in the peak time zone to be included in the peak cut command that is the demand response command. Treat equipment as shut down. The demand response processing unit 29 outputs the operation stop command to the operation plan correction processing unit 28. The operation plan correction processing unit 28 stops a device set as a demand response target device on an operation time chart indicating an operation state (operation schedule) described later. The operation plan correction processing unit 28 outputs an operation stop command for the device set as the demand response device to the control command output unit 34. The control command output unit 34 outputs the operation stop command input from the operation plan correction processing unit 28 to the monitoring control device 2 that controls devices such as water facilities and pumps, and the monitoring control device 2 operates the corresponding device. Is stopped.

FIG. 9 shows a data structure showing the setting status of the demand response target device stored in the demand response compatible device file unit 25. As shown in FIG. 9, for each device installed in each facility, either a demand response target device setting (◯ mark) or a demand response target device non-setting (× mark) is stored. In FIG. 9, No. 1 water pump and No. 2 water pump installed in water purification plant 7, No. 1 water pump and No. 2 water pump installed in A water reservoir 9a, and No. 1 installed in B water reservoir 9b The distribution pump No. 3 to the distribution pump is a demand response target device non-setting device, and shows a case where other various pumps are set as demand response target devices.
FIG. 10 is a diagram illustrating an example of an operation state in the case where the linked operation and the demand response target device are set as the operation conditions of the main device at the time of the demand response command. The difference from the first embodiment is that a “demand response target device” column is newly provided between the “linked interlock” column for setting the linked operation condition and the “rated power (kW)” column. ing. This “Demand-sponsor target device” column has a pull-down button. The operator sets each device installed in each facility as a demand response target device setting (marked with a circle) and a demand response target device not set. (×) can be easily set. The example shown in FIG. 10 shows a case where a water utility as a power consumer has concluded a contract for contract power 2 (P2: 1100 kW) with an electric power company. In FIG. 10, the right column shows, as an example, an operation time zone from the operation start time to the operation end time of each pump at the time from 9:00 am to 6:00 pm (18:00). The setting of the operation time zone for each pump is the same as in the first embodiment, and a description thereof is omitted. As shown in FIG. 10, in all the periods from 9:00 am to 6:00 pm (18:00), the predicted power usage is an operation plan (operation plan) that does not exceed the contract power 2 (P2). Yes.

Next, the setting of the demand response target apparatus by the operator will be described for each apparatus installed in each facility. FIG. 11 is a display example of a terminal display screen when setting the interlocking operation and demand response compatible device shown in FIG. 10. As shown in FIG. 11, the terminal display screen 150 of the terminal device 15 connected to the electric energy control operation planning device 1 includes a first display area 151, a second display area 152, a setting button 153, and an execution button 155. Is done. The terminal display screen 150 in FIG. 11 does not have the time shift button 154 shown in FIG. The system diagram displayed in the second display area 152 is the same as that shown in FIG. Moreover, the interlocking operation interlock setting with respect to each apparatus of each facility displayed on the 1st display area 151 is performed similarly to the above-mentioned FIG. While referring to the system diagram displayed in the second display area 152, the operator considers a case where a demand response command, for example, a peak cut command is received from the power supply system 17 via the aggregator 16. Then, by using the pull-down button in the “demand response target device” column, either the demand response target device setting or the demand response target device non-setting is selectively set for each device. Thereafter, when the setting button 153 is designated, the demand response target device setting unit 32 (FIG. 2) stores the demand response target device setting content displayed in the first display area 151 in the demand response corresponding device file unit 25. To do. At this time, the data structure stored in the demand response compatible device file unit 25 has the contents shown in FIG.
In FIG. 11, the elevation data may be combined and displayed in the system diagram displayed in the second display area 152. In this case, the operator can further improve the convenience in determining the device that can be stopped when receiving the peak cut command as the demand response command while referring to the altitude data. Further, the second display area 152 may be a multi-window method, and detailed information of the area in the system diagram that is appropriately designated by the operator may be displayed in a pop-up on a new window.

  FIG. 12 is a diagram showing an operation status when a demand response command is supported by stopping operation of a specific device among demand response target devices, and shows contents displayed in the first display area 151 shown in FIG. . In the example illustrated in FIG. 12, the demand response command is transmitted from the power supply system 17 and received by the communication processing unit 30 via the aggregator 16. As shown in FIG. 12, when the demand response processing unit 29 receives a peak cut command as a demand response command at 1:30 pm (13:30) via the communication processing unit 30, the operation plan correction processing unit 28 performs the following operation. In order to achieve the power reduction target (for example, 300 kW reduction) defined in advance by the above-mentioned demand response contract, the operation plan correction processing unit 28 refers to the demand response corresponding device file 25, and among the devices in the operation time zone. A device set as a demand response target device is selected in the demand response compatible device file unit 25. In the selection of this device, the device assigned with the operation time zone is selected in the time zone specified by the demand response command, in FIG. 12, the time zone from 1:30 pm to 4 pm. Of the plurality of selected demand response target devices, a combination of demand response target devices that can achieve the power reduction target is determined based on the rated power value of the demand response target device. In the example shown in FIG. 12, the No. 4 intake pump installed in the intake 5 (operation stoppage period: 3:00 pm to 4:00 pm), the No. 3 intake pump installed in the transfer pump station (operation stoppage period: 1 pm 3:30 pm to 3 pm), and the combination of demand-responsible equipment that the No. 3 water distribution pump (operation stoppage period: 3:00 pm to 4:00 pm) installed in the A reservoir 9a can achieve the power reduction target As determined.

  The operation plan correction processing unit 28 outputs a stop command to the devices included in the determined combination to the monitoring control device 2 via the control command output unit 34. The supervisory control device 2 controls to stop the operation of the device corresponding to the received stop command. When the demand response command does not include the power amount reduction time zone but includes only the power amount reduction start time, the operation plan correction processing unit 28 combines the demand response target devices that can achieve the power reduction target. This determination process is repeatedly executed at a predetermined cycle, and the operation plan is corrected to achieve the power reduction target. In this case, the operation resumption time of the equipment that has been stopped in response to the demand response command is when the demand response cancellation command is received from the aggregator 16 via the power supply system 17. In the example illustrated in FIG. 12, when the demand response cancellation command is received from the aggregator 16 at 4 pm, the operation plan correction processing unit 28 performs the operation restart for the equipment that has been stopped in response to the demand response command. The operation command is output by the monitoring control device 2 via the control command output unit 34 to control the operation.

FIG. 13 shows an operation flow of the electric energy control operation planning device 1. Since the processing from step S101 to step S103 shown in FIG. 13 is the same as that in the first embodiment, description thereof is omitted here. In step S <b> 201, the demand response target device setting unit 32 receives a demand response target device setting for each device of the water facility input by the operator via the first display area 151. Thereafter, in step S202, the demand response target device setting unit 32 determines whether the demand response target device setting status for each received device, that is, the demand response target device setting or the demand response target device non-setting, Store in the file unit 25.
In step S <b> 203, the demand response processing unit 29 monitors the reception of a peak cut command that is a demand response command from the aggregator 16 via the communication processing unit 30. If no peak cut command is received, the process enters a standby state and the process ends. On the other hand, when the peak cut command is received, the process proceeds to the next step S204. The operation plan correction processing unit 28 that has received the peak cut command from the demand response processing unit 29 refers to the demand response-compatible device file unit 25, and among a plurality of operating devices, a plurality of devices set as demand response target devices Extract combinations. For each combination of a plurality of extracted devices, the rated power value of each device included in the combination is read from the device-specific rated power value file unit 23. Based on the read rated power value, a combination of demand response target devices that satisfy the power reduction target included in the peak cut command is selected and specified (step S204).

  In step S205, the operation plan generation unit 27 reads the combination of the demand response target devices determined in step S204 and the rated power value of the device in the other operation time period from the device-specific rated power value file unit 23, Calculate the predicted power usage at each time. Subsequent steps S106 and S107 are the same as in the first embodiment, and the time series data of the calculated predicted power usage is displayed in the first display area 151 in the terminal display screen 150, and the process is terminated.

  FIG. 14 is a diagram illustrating an example in which the actual power consumption is superimposed and displayed on the driving situation when the demand response command shown in FIG. 12 is supported. At the end of step S107 in FIG. 13 described above, the driving status shown in FIG. 12 is displayed in the first display area 151. In this display state, the operation plan generating unit 27 refers to the power amount time-series data file unit 21 and reads the actual power usage amount of each device up to the current time. Here, the actual power usage amount of each device is collected from the monitoring control device 2 by the power usage amount collection unit 18 in a predetermined cycle, and is stored in the power amount time series data file unit 21 as time series data. The operation plan generation unit 27 cumulatively processes the actual power usage amount up to the current time for each device that has been read out, and obtains the total power usage amount. As shown in FIG. 14, the obtained total power consumption is superimposed and displayed on the time series data of the predicted power usage as, for example, a bar graph as the actual power usage. As a result, the operator can easily grasp the actual power usage up to the current time as compared with the predicted power usage.

  FIG. 15 is a diagram showing hourly charges in the summer and other seasons stored in the hourly charge file unit 26 of the electric energy control operation planning device 1. This hourly fee table is stored in advance in the hourly fee file unit 26 by the hourly fee setting unit 33. FIG. 16 is a diagram showing an example in which a charge for each time zone is further superimposed and displayed on the driving situation when the demand response command shown in FIG. 14 is supported. The operation plan correction processing unit 28 refers to the hourly charge file part 26 and calculates the hourly power charge during operation of the device. The calculation of the power charge by time zone is performed by the operation plan correction processing unit 28 based on the power rate unit price by time zone set in the time zone charge file unit 26 and the actual power usage amount described in FIG. Is required. Also, the predicted power charge after the current time is obtained by the operation plan correction processing unit 28 based on the hourly charge unit price and the predicted power usage (total value of the rated power value of the operation-scheduled equipment). The operation plan correction processing unit 28 evaluates the power charge upper limit value based on the predicted power charge and corrects the operation time zone of the operation-scheduled device in a time zone in which the power charge can be reduced.

In the present embodiment, when a demand response command is received, the operation of a desired device is stopped from the devices set as demand response target devices in advance. However, the present invention is not limited to this. For example, instead of stopping the operation of the desired device, the operation time zone of the desired device may be moved (time-shifted) from the devices set as demand response target devices in advance.
Further, in this embodiment, the case where a demand response command output as a peak cut command is received from an electric power company has been described as an example. However, the present invention is not limited to this. For example, a target power consumption is set and the target power consumption is equal to or less than this target power consumption The operation of a specific device may be stopped, or the operation time zone of each device may be moved (time shift). That is, if the operation of a specific device is stopped or the operation time zone of each device is moved (time shift) so as to be equal to or less than a predetermined value (power consumption) arbitrarily set by the operator, Any aspect is included.

According to the present embodiment, in addition to the effects of the first embodiment, since a demand response target device can be set in advance, a demand response command from an electric power company can be handled in real time.
In addition, the influence of the equipment that has been shut down in response to the demand response command is corrected at regular intervals by the water operation plan planning function provided in the monitoring and control device 2, and the corrected water operation plan is again converted into the electric energy control operation planning device. By developing the operation schedule of each device in the water supply facility in 1 and maintaining the demand response, the operation of each device in which the water operation plan and the electric energy control operation plan are coordinated can be realized.

  Furthermore, according to the present embodiment, when the hourly power rate system can be applied, a predicted power rate based on the predicted power usage is obtained, and the upper limit of the power rate is evaluated and the operation time zone is changed. Electricity charges can be reduced.

  In FIG. 17, the operation | movement flow of the electric energy control operation | use planning apparatus of Example 3 which concerns on the other Example of this invention is shown. In the first embodiment, a configuration in which the operator moves (time shifts) the operation time zone of a desired device with respect to the operation status (operation schedule) of each device of the water supply facility displayed in the first display area of the terminal display screen. It was. On the other hand, the present embodiment is different from the first embodiment in that the electric energy control operation planning apparatus is configured to present to the operator a combination candidate of devices that should move (time shift) in the operation time zone. Other configurations are the same as those of the first embodiment, and redundant description is omitted below.

As shown in FIG. 17, the process from step S101 to step S103 for setting the interlock operation interlock for each device in the water supply facility is the same as that in the first embodiment. In step S301, when the operation plan correction processing unit 28 detects an instruction input to the time shift button 154 in the terminal display screen 150, the operation plan correction processing unit 28 recognizes that a time shift request by the operator has occurred.
Thereafter, the operation plan correction processing unit 28 refers to the linked operation interlock file unit 24, and selects a plurality of devices from the devices for which the linked operation interlock is set or the devices for which the linked operation interlock is not set. A plurality of combinations (hereinafter referred to as a plurality of combinations) are extracted. That is, the operation plan correction processing unit 28 extracts a plurality of combinations of devices that can move (time shift) the operation time zone based on the presence / absence (set / non-set) of the interlock operation interlock flag (step S302). Here, when extracting a combination of devices, for example, the priority of the device for which the independent operation condition is specified (linked operation interlock is not set) is set to the priority of the device for which the operation condition is specified (linked operation interlock setting). It is desirable to set higher than the priority. The operation plan correction processing unit 28 outputs the extracted plural sets of information to the operation plan generation unit 27.

In step S303, the operation plan generator 27 calculates a difference ΔP between the contract power 1 (P1) and the contract power 2 (P2). Here, the contract power 1 (P1) is, for example, 1400 kW as in the first embodiment, and the contract power 2 (P2) is, for example, 1100 kW. Therefore, the difference ΔP is 300 kW.
The operation plan generation unit 27 reads out the rated power values of the devices constituting each group from the device-specific rated power value file unit 23 for each of the plurality of combinations extracted in step S302, and totals the rated power values for each group. To do. Then, a plurality of device combination candidates that fall within the difference ΔP (for example, 300 kW) are extracted (step S304).

In step S305, in the first display area 151 in the terminal display screen 150, for example, as shown in FIG. Thus, the operator selects a desired candidate from a plurality of candidates that overlap in the first display area 151 and are displayed in the plurality of windows, so that the selected window becomes active. Here, the lower the rated power value aggregated for each set, the higher the candidate rank is set, and the lower is displayed on the front side of the screen.
In step S306, in the window selected in step S305, the movement (time shift) of the operating time zone of the device to a desired time zone is accepted by an input device such as a mouse by the operator. The operation plan generation unit 27 reads the rated power value of each device for each time shift from the device-specific rated power value file unit 23, and calculates the predicted power usage amount at each time based on the read rated power value. . Subsequent steps S106 and S107 are executed in the same manner as in the first embodiment.

  According to the present embodiment, in addition to the effects of the first embodiment, the selection of the device that should move (time shift) the operation time zone by the operator is further facilitated.

The present embodiment is different from the third embodiment in that the power amount control operation planning device 1 automatically executes the shift (time shift) of the operation time of the equipment installed in the water supply facility. The rest of the configuration is the same as that of the third embodiment, and therefore, a duplicate description is omitted below.

The processing from step S101 to step S304 shown in FIG. 18 is the same as that in the third embodiment. In step S401, the operation plan correction processing unit 28 moves (time shifts) the operation time zone of each device to another time zone for each device combination candidate extracted in step S304. The operation plan generation unit 27 reads out and sums up the rated power values of the devices constituting the combination candidates from the device-specific rated power value file unit 23 for each combination candidate of devices after the time shift. Then, the predicted power consumption is calculated based on the counting result and the rated power value of other devices in the same time period.
The operation plan correction processing unit 28 performs a shift (time shift) of the operation time zone of the devices constituting the combination candidate that is the smallest among the predicted power usage amounts for each candidate calculated in step S401 (step S402). ). The time series data of the predicted power usage after the time shift is executed is stored in the power amount time series data file unit 21 by the operation plan generation unit 27 (step S403). In step S403, the time series data of the predicted power usage after the time shift stored in the power quantity time series data file unit 21 is displayed in the first display area 151 in the terminal display screen 150 (step S404), and processing Exit.
