Description

Demand control device and program

The present invention relates to a demand control device and a program, and in particular, to ranking of equipment to be controlled for power supply.

In the demand control, the power consumption within the demand time period is predicted, and when the predicted power consumption is predicted to exceed the target amount, predetermined energy saving control is performed. As energy saving control, for example, conventionally, each facility of a facility such as a building, a facility that can be stopped, a facility that does not want to be stopped if possible, a facility that cannot be stopped, or a facility that cannot be stopped, etc., according to a level setting standard based on the possibility of stopping, etc. Divide into levels. Then, an expected amount of power reduction (hereinafter, “surplus”) is set for each level. The level indicates the priority of the equipment to be controlled for power supply. In the energy saving control, the operation is switched to the operation with the smaller power consumption in order from the facility with the lower level (the facility group that can be stopped preferentially) according to the required power reduction amount. Alternatively, the operation of the equipment is stopped in order from the equipment having the weakest level to eliminate power consumption. In this way, control is performed so that the reduction target of the power consumption can be achieved.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of the entire system including an embodiment of the demand control device according to the present invention. FIG. 1 shows a server 2, an entry / exit management system 4, and a demand control device 10. The demand control device 10 acquires equipment information, operation result information, and operation information used for demand control from, for example, one or a plurality of server computers included in a building management system. The server 2 is illustrated.

Facility information includes information on each facility. For example, the equipment information includes information such as the type, model, model number, specification (rated power, etc.), and installation location of each equipment. The operation result information includes information on operation results of each facility. For example, the operation result information includes the amount of power used, in addition to the operating state (operating or non-operating) of each facility. The operation information includes information on the operation of the facility or each facility. For example, the operation information includes the energy saving control target time in the facility.

The entry / exit management system 4 is a system for managing entry / exit of a facility where the demand control device 10 is installed. The demand control device 10 acquires the number of persons in each area such as a room in the facility from the entrance / exit management system 4.

The demand control device 10 is a device that performs demand control. The demand control device 10 predicts whether the power consumption of the facility at the end of the demand time period exceeds a preset target value. If the power consumption of the facility at the end of the demand time period is predicted to exceed, the demand control device 10 performs energy saving control of each facility of the facility so that the power consumption of the facility at the end of the demand time period does not exceed the target value. carry out. Specifically, the demand control device 10 performs control such that the operation of one or a plurality of facilities is restricted so that the reduction target of the power consumption can be achieved. “Limiting the operation of equipment” means switching to an operation that consumes less power, or stopping the operation of the equipment to eliminate power consumption. Note that, as is clear from the above description, facilities that can be subjected to energy saving control are installed in the facilities. The equipment that can be subjected to the energy saving control is an electrical equipment that is supplied with electric power and operates, such as an air-conditioning equipment or a lighting equipment.

エネルギー Energy saving control is control to limit the operation of equipment and reduce the amount of power used in the equipment. The ultimate limitation of the operation of the equipment in the energy saving control is the suspension of the operation of the equipment. For example, turning off two fluorescent tubes out of the illumination having four fluorescent tubes corresponds to switching to operation with low power consumption. However, in the present embodiment, for convenience, a description will be given assuming that control for stopping the operation of the facility is energy saving control. That is, the energy saving control may be considered to be equivalent to the stop control of the operation of the equipment.

FIG. 2 is a hardware configuration diagram of a computer forming the demand control device 10 according to the present embodiment. The demand control device 10 according to the present embodiment can be realized by a general-purpose hardware configuration existing before, such as a personal computer (PC). That is, as shown in FIG. 2, the demand control device 10 includes a CPU 21, a ROM 22, a RAM 23, a hard disk drive (HDD) 24, a mouse 25 and a keyboard 26 provided as input means, and a display 27 provided as display means. An input / output controller 28 to be connected and a network interface (IF) 29 provided as communication means are connected to an internal bus 30.

Returning to FIG. 1, the demand control device 10 includes an index data generation unit 11, a control target equipment extraction unit 12, an equipment control information generation unit 13, a demand control unit 14, an index data storage unit 15, an equipment control information storage unit 16, It has a performance information storage unit 17. Note that components not used in the description of the present embodiment are omitted from the drawings.

The index data generation unit 11 generates index data that the equipment control information generation unit 13 refers to for generating equipment control information. The operation rate calculation unit 111, the remaining power calculation unit 112, and the control priority setting unit 113 included in the index data generation unit 11 generate the operation rate, the remaining power, and the control priority, which are the index data, respectively. Indices handled in the present embodiment will be described later. The control target equipment extraction unit 12 is provided as an extraction unit, and extracts equipment to be subjected to energy saving control by the demand control unit 14 from among the equipment of the facility with reference to the operation rate of each equipment. The equipment control information generation unit 13 is provided as a setting unit, and sets the priority of energy saving control for each equipment extracted by the control target equipment extraction unit 12. When setting the priorities, the facility control information generator 13 refers to the index data. Further, as described later, the facility control information generation unit 13 sets a priority level (hereinafter, simply “level”) as a priority order for each facility based on the index data. The demand control unit 14 performs demand control. If the power consumption of the facility at the end of the demand time period is predicted to exceed the preset target value, the demand control unit 14 sets the power consumption of the facility at the end of the demand time period to not exceed the target value. Control the operation of the equipment. The demand control unit 14 in the present embodiment controls the operation of the equipment in the order of priority set by the equipment control information generation unit 13, specifically, in the level unit set for each equipment.

The index data storage unit 15 stores the index data generated by the index data generation unit 11. The equipment control information storage unit 16 stores equipment control information generated by the equipment control information generation unit 13. The control result information storage unit 17 stores information on the execution contents of the demand control in the demand control unit 14 as control result information. Details of these pieces of information will be described later.

Each component (11 to 14) of the demand control device 10 is realized by a cooperative operation of a computer forming the demand control device 10 and a program operated by a CPU 21 mounted on the computer. Each of the storage units (15 to 17) is realized by the HDD 24 or the RAM 23 mounted on the demand control device 10. However, an external storage means may be used via a network.

プログラム The program used in the present embodiment can be provided by communication means. Further, the program used in the present embodiment can be provided by being stored in a computer-readable recording medium such as a CD-ROM or a USB memory. The program provided from the communication means or the recording medium is installed on a computer. Various processes are realized by the CPU of the computer sequentially executing the programs.

FIG. 3 is a diagram showing information related to the index in the present embodiment. The index in the present embodiment is used when classifying each facility. Here, each index will be described.

デマンド In the demand control according to the present embodiment, the power consumption in the facility within the demand time period is predicted. If the power consumption of the facility at the end of the demand time period is expected to exceed a preset target value, one or more power consumptions of the facility at the end of the demand time period will not exceed the target value. Energy saving control (stop in the present embodiment) is performed so as to limit the operation of the equipment of (1). It should be noted that contract power with a power company may be set as the target value, or other power consumption (usually less than the contract power) may be set as the target value.

In the present embodiment, a target power reduction is achieved by assigning a priority to each facility and stopping each operation in the priority order. The target power reduction amount can be generally calculated by subtracting the target value from the facility power consumption predicted at the end of the demand time period. However, the target amount of power reduction need not be limited to this.

設備 In this embodiment, each facility is classified into a plurality of levels. The level to which each facility belongs corresponds to the priority of the facility. The demand control unit 14 performs control such that the operation is stopped in order from the highest priority level in units of level. Since each level will include one or more facilities, the operation of the plurality of facilities will be stopped simultaneously. That is, it is possible to reduce the power consumption by the total value of the remaining power of each facility included in the level to be controlled. However, if the equipment to be controlled is stopped before being stopped by the energy saving control, the power consumption corresponding to the remaining power of the equipment cannot be reduced, and the target power reduction cannot be achieved. There is a fear.

Therefore, in the present embodiment, when prioritizing each facility (in this embodiment, when setting a level for each facility), the priorities are given by referring to the index shown in FIG. The target power reduction can be more reliably achieved.

FIG. 3 shows, as indices, the operation rate, control priority, remaining power, reliability of remaining power, the number of times of energy saving control, responsiveness of energy saving control, and the number of occupants.

The operating rate is the operating rate of each facility. A high operation rate indicates that there is a high possibility that the vehicle is in operation when the energy saving control is started, that is, that there is a high possibility that electric power is being used. Therefore, by giving priority to the equipment having a high operation rate as the stop control target, the possibility of reducing the power consumption corresponding to the remaining power of the equipment increases. As the operation rate, a ratio of the operation time to a predetermined period (for example, one day) may be calculated. Further, as the operation rate, a ratio of the operation time to the time during which the energy saving control is performed (for example, working hours) may be calculated. Alternatively, the average of the operation rates of a plurality of periods may be used as the operation rate of the facility. The operation rate calculation unit 111 calculates the operation rate by referring to the operation information and the operation result information of the server 2 in response to a request from the control target equipment extraction unit 12 or the equipment control information generation unit 13.

The control priority is an index indicating the priority to be set as the power supply control target of each facility. The control priority is set for each facility such that a facility, such as a building manager, which is considered to be actively controlled by the user for energy saving is preferentially controlled. For example, if both the president's office and the corridor are equipment, a higher control priority is assigned to the corridor equipment so that the equipment in the corridor such as air conditioning equipment or lighting equipment is controlled to stop before the equipment in the president's office. Set for By setting the control priority by the user, it is possible to minimize the dissatisfaction of the facility user and to prevent a decrease in comfort. The control priority setting unit 113 displays a setting screen on the display 27 at the time of the level setting process, and allows the user to input a control priority for each facility. In the present embodiment, the control priority is set at three levels of “high”, “medium”, and “low”. However, this is only an example, and the control priority may be set using another number of levels.

Remaining power is an index indicating the power that can be reduced by each facility, and is the power reduction that can be expected when energy saving control is performed on each facility. By giving priority to equipment with a large spare capacity, it is possible to achieve the target amount of power reduction with the minimum necessary equipment. And it becomes possible to minimize user dissatisfaction. The remaining power may be calculated by installing a wattmeter in each facility and measuring the power consumption of the operating facility. Further, the rated power of each facility may be set as the remaining power. The remaining capacity calculation unit 112 calculates the remaining capacity with reference to the operation result information or the equipment information of the server 2 at the time of the level setting process. In the present embodiment, as shown in FIG. 7, the remaining power is set as a numerical value. However, the reserve may be set at a plurality of levels such as the control priority.

信頼 Reliability of spare capacity is an index that indicates the reliability of spare capacity of each facility. The reliability of the reserve is obtained by referring to the average error between the estimated reserve and the actual reserve when the energy saving control is performed on each facility. The average error rate may be referred to in consideration of the magnitude of the remaining power (absolute value). By preferentially controlling equipment with a small error (rate) as a control target, the amount of power reduction can be calculated more accurately, so that a more reliable reduction target can be achieved. The index data generator 11 calculates an average error (rate) with reference to the equipment information and the operation result information of the server 2 at the time of the level setting process. In the present embodiment, it is assumed that the reliability of the remaining power is set as a numerical value. However, the reliability of the remaining power may be set at a plurality of levels such as the control priority.

The number of times of energy saving control is an index indicating the frequency (control number) of each facility being controlled by the demand control unit 14, and is the number of times energy saving control is performed on the facility within the latest predetermined period. By giving priority to the equipment with a small number of executions so that the number of times the energy saving control is executed for each equipment is about the same, it is possible to maintain a sense of fairness. The index data generation unit 11 refers to the operation result information of the server 2 at the time of the level setting process, and acquires the number of times of performing the energy saving control within a predetermined period.

応答 The responsiveness of the energy saving control is an index indicating the time required from the start of control of each facility by the demand control unit 14 to the reduction of power. By giving priority to equipment with a high response speed, it is possible to achieve the reduction target at an early stage. The index data generation unit 11 calculates the responsiveness of the energy saving control with reference to the operation result information or the equipment information of the server 2 at the time of the level setting process. In the present embodiment, it is assumed that the responsiveness of the energy saving control is set by a numerical value. However, the responsiveness of the energy saving control may be set at a plurality of levels such as the control priority.

人数 The number of occupants is an index indicating the number of occupants in the installation area of each facility. By actively controlling facilities in an area where the number of people is small, it is possible to minimize user dissatisfaction. The index data generation unit 11 obtains the number of persons in the area by making an inquiry to the entry / exit management system 4 at the time of the level setting process.

When the index data generation unit 11 generates the above-described index as needed, the index data generation unit 11 sets and registers the index in the index data table of the index data storage unit 15 described later.

Next, the operation in the present embodiment will be described. In performing the demand control in the present embodiment, it is necessary to classify each facility of the facility into levels. This embodiment is characterized in that facility control information is generated by performing facility level division based on the index shown in FIG. Therefore, in the present embodiment, two steps are taken. That is, as shown in FIG. 4, a control target facility extraction process (step 10) for extracting facilities to be classified into levels (in other words, facilities to be subjected to energy saving control) from the facilities of the facility, A level setting process (step 20) for classifying each facility into levels is executed. These processes can be executed independently of the demand control. For example, considering that it is desired to use real-time data such as the number of occupants, it is not necessary to execute these processes when it is predicted that the power consumption of the facility at the end of the demand time period will exceed the target value. It is suitable. First, details of the control target facility extraction processing will be described with reference to the flowchart shown in FIG.

(4) The operation rate calculation unit 111 calculates an operation rate for all the facilities of the facility (Step 101). As the operation rate, the ratio of the operation time of the equipment to the predetermined period can be calculated. The operating time of the equipment can be obtained from the operation result information. Further, the predetermined period may be the entire time (for example, 24 hours a day) as described above, or may be a time zone (for example, working time) in which the energy saving control is performed. The time period during which the energy saving control is performed can be obtained by referring to the operation information of the equipment.

(4) Upon acquiring the operation rate calculated by the operation rate calculation unit 111, the control target equipment extraction unit 12 first excludes the equipment whose operation rate is 100% from the control target candidates (step 102). It is considered that the equipment whose operation rate is 100% is equipment that must always be operated at all times, for example, air conditioning equipment in a server room. Depending on how to set the period for which the operation rate is to be calculated, for example, the air conditioning equipment in the server room may be temporarily stopped during maintenance. For example, a predetermined value close to 100% may be set as the operation rate of the exclusion target.

Next, the control target equipment extraction unit 12 excludes the equipment whose operation rate is X% or less from the control target candidates (Step 103). For example, when X = 0, this facility is not operating at all in the predetermined period for calculating the operation rate. Even if such equipment is subjected to energy saving control, no reduction in power can be expected, so the controlled equipment extraction unit 12 excludes such equipment from control object candidates from the beginning. For these reasons, "X" is preferably a number close to zero. However, in practice, “X” may be appropriately set according to the operation.

As described above, the control target equipment extraction unit 12 extracts the equipment to be subjected to the energy saving control with reference to the operation rate of each equipment.

Next, the details of the level setting process will be described with reference to the flowchart shown in FIG. In this process, a level is set for each facility extracted in step 20 with reference to the index data. For this purpose, an index data table shown in FIG. 7 is set (step 201). That is, in the index data table, each index data of the control priority, the spare capacity, and the operation rate is set for each facility extracted in step 10. As described above, the control priority setting unit 113 allows the user to set the control priority for the equipment. The operation rate calculation unit 111 obtains necessary information from the server 2 and calculates the operation rate of each facility. The spare capacity calculation unit 112 acquires necessary information from the server 2 and calculates the spare capacity of each facility.

The index data generation unit 11 can also generate other index data that is not included in the index data table, such as the reliability of remaining capacity. Here, for the sake of convenience, a case will be described as an example in which level division is performed using three indices of the operation rate, the control priority, and the spare capacity.

In the present embodiment, the following processing is executed for each facility extracted in step 10 with reference to the index data table. Therefore, the processing load required for the level setting process can be reduced as compared with the case where each facility is not extracted. In the description of this process, each facility extracted as a target of the energy saving control in step 10 is simply referred to as “facility” unless otherwise specified.

では In the present embodiment, the levels are set in order from the equipment that is likely to be subjected to energy saving control. In the present embodiment, the lower the number, the higher the level, and the energy saving control is performed in order from the equipment corresponding to the higher level.

{Circle around (1)} First, a variable α indicating a level is set to 1 (step 202). Then, the facility control information generation unit 13 refers to the index data table and extracts the facility having the highest control priority among the facilities that have not been classified into levels (step 203). The facilities that are not classified into levels are facilities that have not been added to any of the levels in the subsequent step 205. In the present embodiment, since control priorities are set at three levels of “high”, “medium”, and “low”, a plurality of facilities may be extracted at the same time.

Next, the facility control information generation unit 13 extracts the facility with the highest operation rate from the extracted facilities (Step 204). Then, the extracted equipment is added to the level α (step 205). Here, since the level is still “1”, the facility is classified into level 1. Then, the facility control information generation unit 13 adds the remaining capacity of the facility to be added to the remaining capacity of level 1 (step 206). Since the remaining power of each level is initialized to “0”, the remaining power obtained by the addition is the power that can be reduced at the level.

If the processing for all the facilities has not been completed (N in step 207), the facility control information generation unit 13 compares the remaining power of the level with the target reduction power. The target reduction power is set in advance for each level. The target power reduction for each level is the power reduction target for the level. If the remaining power at this level has not reached the target power reduction (N in step 208), the process returns to step 203. Then, the processing shifts to the processing for the equipment that has not been classified. Then, steps 203 to 207 are repeated, and when the remaining power of the level becomes equal to or more than the target reduction power (“Y” in step 208), 1 is added to the level α (step 209), so that the next level (priority) (A level one degree lower). In the present embodiment, the number of levels for classifying the equipment is determined in advance, and when the number of levels is reached (“Y” in step 210), the process ends. Otherwise (“N” in step 210), the above-described processing (steps 203 to 209) is repeatedly executed. If all the facilities can be classified into levels ("Y" in step 207), the process ends.

In step 205, only one facility is added to the level α. However, it can be assumed that there is a facility having the same operation rate in step 204. When it is desired to achieve the target reduction power of the level α with a few facilities, it is sufficient to select a facility having the maximum spare power. If not, or if there are a plurality of facilities having the same spare capacity, processing is performed so as to preferentially extract the facilities registered in the higher rank of the index data table and to always extract one facility.

設備 When the facilities are classified as described above, the facility control information generating unit 13 registers the execution result of the level setting process in the facility control information storage unit 16 as the facility control information. The facility control information is configured such that one or a plurality of facilities are linked to each level.

When the demand control unit 14 predicts that the power consumption of the facility at the end of the demand time period exceeds a preset target value, the demand control unit 14 performs energy saving control in order from the highest-level facility with reference to the facility control information. . That is, the equipment allocated to level 1 is first subjected to the energy saving control, and the supply of power is stopped. As a result, it is expected that the power consumption will be reduced by more than the target reduction power set for level 1. If the target power reduction amount has not been reached, the demand control unit 14 performs energy saving control on the next highest level 2 facility. As described above, by performing the energy saving control in order from the equipment of the higher level, the demand control unit 14 controls the operation of the equipment so that the power consumption of the facility at the end of the demand time period does not exceed the target value.

(4) In the present embodiment, the priority order (level) for limiting the power supply for each facility is set based on the operation rate. Therefore, it is possible to preferentially set the equipment having a high possibility of actually using the electric power as the energy saving control target. This makes it possible to further reduce the difference between the reduced power (surplus) expected when the corresponding facility is controlled for energy saving and the target reduced power. As a result, it is possible to more reliably achieve the target amount of power reduction.

In the present embodiment, each facility is divided into levels based on the control priority and the operation rate. However, the control priority and the operation rate may be used as indices to be referred to for extracting the equipment, such that the equipment having a large spare capacity is preferentially extracted. In addition, using the other indices shown in FIG. 3, specifically, each facility is divided into levels using the reliability of the remaining power, the number of times of energy saving control, the responsiveness of energy saving control, and the number of people in the room. You may. In the present embodiment, in steps 203 and 204 shown in FIG. 6, equipment is extracted using an index. The facility control information generation unit 13 may execute a process of extracting a facility based on the other index, included in the processing of these steps, or instead of the processing of one of the steps.

For example, the reliability of spare power and the responsiveness of energy saving control are indices closely related to the accuracy and efficiency for obtaining the target amount of power reduction, like the operation rate. Therefore, at least one of the reliability of the remaining power and the responsiveness of the energy saving control may be added to the condition for simply extracting the equipment, or at least one of the reliability of the remaining power and the responsiveness of the energy saving control instead of the operation rate. Or may be used.

回数 Furthermore, the number of energy-saving controls and the number of occupants are closely related to comfort, as are the control priorities. Therefore, at least one of the number of times of energy saving control and the number of people in the room may be added to the condition for simply extracting the equipment, or at least one of the number of times of energy saving control and the number of people in the room may be used instead of the control priority.
