Description

Electricity system reforms are underway on both the demand and supply sides of electricity. Demand Response (DR) allows consumers to curb electricity usage in response to electricity tariff pricing or incentive payments when electricity wholesale market prices soar or power grid reliability declines. It is to change the power consumption pattern. A virtual power plant (VPP) integrates multiple small-scale private power generation facilities, such as corporate private power generation facilities and power demand restraints for electric vehicle storage batteries, as if it were a single power plant. It is also called a virtual power plant by controlling it.

Patent Document 2 points out that when an electric device as a facility owned by a user is controlled by a demand response, the time when the user cannot freely use the electric device increases, and the comfort of the user may be impaired. .. Therefore, a demand that estimates the user's life pattern during the demand response period, assigns one of a plurality of demand response control methods based on the estimation, and controls the user's electrical equipment without impairing the user's comfort. The response control method is disclosed.
Patent Document 3 compares the daily power transition of a hospital with the residential facilities of an elderly home or an elderly condominium. In residential facilities, there is a first peak around 7 am, it decreases after noon, and there is a second peak around after dinner, but in hospitals, outpatients increase from morning to afternoon and peak after noon. , Mutual power transitions are complementary. Therefore, by installing one power storage device in the hospital and a total of four power storage devices in multiple residential facilities and controlling the charging and discharging of these in an integrated manner, the daily power consumption of the hospital and multiple residential facilities combined. The transition is leveled.

The demand response control system according to the present disclosure divides a plurality of facilities installed in a building into a plurality of groups, one controller for each group that manages the facilities belonging to each group, and power storage having a predetermined storage capacity. It is equipped with a device and a building management device that centrally manages a plurality of controllers, and the controllers are divided into control terminals that control the operation of equipment belonging to the group, monitoring terminals that monitor the operating status of equipment belonging to the group, and groups. A building management device that has a power switching terminal that switches the power supply destination to the equipment to which it belongs to a power company or a power storage device, and a power consumption terminal that outputs the actual power consumption data of the controller, which is the total power consumption of the equipment belonging to the group. stores the baseline power consumption table which is arranged a baseline power consumption of each controller calculated in a predetermined method, from a power company, a period of the reduced power P0 from among power reduction inception H0 Receive the demand response request of the content you want to execute, select the first controller with baseline power consumption corresponding to P0 from the baseline power consumption list, and acquire the actual power consumption of each controller in a predetermined control cycle. However, when the actual power consumption of the first controller deviates from P0 and the dissociated power consumption of the first controller, which is the difference between the actual power consumption of the first controller and P0, exceeds the control allowable range of the demand response control. , Select another controller to be added or replaced with respect to the first controller to make a combination of multiple controllers, and the combination divergence power consumption, which is the difference between the actual power consumption of the combination and P0, is within the control allowable range. A plurality of controllers constituting the combination are set as the control target controller, the power supply from the power company is stopped for the set control target controller, and the necessary power is supplied from the power storage device instead.

In the demand response control system according to the present disclosure, when the actual power consumption of the first controller deviates to less than P0, the second controller having the baseline power consumption corresponding to the dissociated power consumption of the first controller is selected. Then, it is added to the first controller, and the first controller and the second controller form the first combination, and the first deviation power consumption, which is the difference between the actual power consumption of the first combination and P0, is within the control allowable range. set the first controller and the second controller constituting a first combination as the control target controller in the case of, when the first divergence power consumption exceeds the control allowable range, actual power of the second controller and the Select and add a third controller that has baseline power consumption corresponding to the second controller divergence power consumption, which is the difference from the baseline power consumption of the two controllers, and use the first controller, the second controller, and the third controller. It is preferable to repeat this with the second combination and stop the repetition when the divergence power consumption of the combination is within the control allowable range.

According to the above configuration, when the actual power consumption of the first controller deviates beyond P0, adding another controller to the first controller further deviates beyond P0. Therefore, the second controller and the third controller, which have a baseline power consumption lower than the baseline power consumption of the first controller, are replaced with a first combination as a set. The second controller has a baseline power consumption corresponding to the power consumption obtained by subtracting the deviation power consumption of the first controller from the baseline power consumption of the first controller. The third controller has baseline power consumption corresponding to the divergent power consumption of the first controller. Controller deviation current consumption Given that no more than 50% of the baseline power consumption of the controller, (baseline power consumption of the first controller)> (baseline power consumption of the second controller)> (third controller is a baseline power consumption) of.

If no divergence power consumption occurs in either the second controller or the third controller, (actual power consumption of the first combination) = (actual power consumption of the second controller + actual power consumption of the third controller) = P0. Become. When divergence power consumption occurs between the second controller and the third controller, the second controller, which consumes more baseline power, and the fourth controller , which consumes less baseline power than the third controller, are paired. 2 Replace with a combination. The fourth controller has a baseline corresponding to the power consumption obtained by subtracting the divergent power consumption of the second controller from the baseline power consumption of the third controller. Therefore, if divergence power consumption does not occur in the third controller, (actual power consumption of the second combination) = (actual power consumption of the second controller + actual power consumption of the fourth controller) = P0. When the fourth controller has dissociated power consumption, the above process is repeated in the same manner. In this way, even if the actual power consumption of the first controller deviates beyond P0, the first controller is replaced with another combination, and the difference between the actual power consumption of the combination and P0 can be within the control allowable range. For example, by stopping the repetition, the power consumption P0 can be reduced accurately.

A master controller 22 is arranged on the master control panel 18, and a plurality of controllers 24 according to the power consumption of each floor are arranged on the control panel 20 for each floor. In FIG. 1, the CNT number is shown by distinguishing between the master controller 22 and the other controllers 24. One master controller CNT00 is arranged on the master control panel 18. Three controllers 24, CNT11, CNT12, and CNT13, are arranged on the BF floor control panel 20a, which consumes a large amount of power. Two controllers 24 are arranged on the first floor control panel 20b, the second floor control panel 20c, and the third floor control panel 20d on the office floor. Two units of CNT21 and CNT22 are arranged on the first floor control panel 20b, two units of CNT31 and CNT32 are arranged on the second floor control panel 20c, and two units of CNT41 and CNT42 are arranged on the third floor control panel 20d. Is placed. Three controllers 24, CNT51, CNT52, and CNT53, are arranged on the control panel 20e on the 4th floor, which has an employee cafeteria that consumes a lot of power.

The control board arranged in slot number 6 is a control board that controls the signal type is "BO: power supply switching". BO = 1 is a control signal in the power switching unit 62 in which the power supply source for all the equipment 14 under the control of the controller 24 is the power from the electric power company 8. BO = 0 is a control signal in the power switching unit 62 in which the power supply source for all the equipment 14 under the control of the controller 24 is AC power from the power storage device 34 via the AC / DC power conversion device 32. The control signal BO is transmitted to the power switching unit 62 by a signal line drawn from the power switching terminal of the control board arranged in slot number 6.

Power switching unit 62 is a power switch panel Ru you switch the power supply source for the equipment 14 to the controller 24 to jurisdiction. The switching of the power supply destination in the power switching unit 62 is performed by the switching signal from the power switching control board arranged in the slot number 6 in the PLC 60. When the switching signal is BO = 1, the power supply line 42 is connected to the power supply line 30 to which the power from the power company 8 is supplied, and the power supply source for the equipment 14 is the power company 8. When the switching signal is BO = 0, the power supply line 42 is connected to the power supply line 36 to which AC power is supplied from the power storage device 34 via the AC / DC power conversion device 32, and is a power supply source for the equipment 14. Is the power storage device 34. In BO = 0, the power supply line 42, due to being blocked from the power supply line 30, instead of the power supply from the power company 8, so that the alternative Ri switching the power supply from the power storage device 34.

The time for processing S28 is the start time of the first control cycle in the system 10. The time from S22 to S28, which is the demand response control start time, is the control initial setting period for processing S24 and S26.

Then, it is determined whether or not ΔP1 ≠ 0 (S32). When the determination of S32 is denied, ΔP1 = 0 and the power reduction of P0 is realized, so that the first controller is set as the controller to be controlled (S40). The controller to be controlled is a controller 24 that receives control in which the power supply from the electric power company 8 is stopped and the necessary power is supplied from the power storage device 34 instead. In the controller to be controlled, BO = 0 is output from the PLC 60 as a power switching signal to the power switching unit 62 under the control of the building management device 16, and the power supply source of each facility 14 belonging to the set control controller is the electric power company. It is switched from 8 to the power storage device 34.

If S32 is affirmed, then it is determined whether or not ΔP1 is within the control allowable range in the demand response control (S34). The request from the electric power company 8 is within the permissible range of the reduced power P0 over the period H0 (± ΔP0), but even during the period H0, during one control cycle T in which the period H0 is divided into a plurality of parts. However, the actual power consumption AP of each controller 24 fluctuates. In consideration of this fluctuation, it is preferable to set the control allowable range in the demand response control to be smaller than (± ΔP0). As an example, {± (1/2) ΔP0}, which is half of (± ΔP0), is set as the control allowable range (± Δs) in the demand response control. Therefore, the determination of S34 is whether or not {−Δs ≦ (AP1-P0) ≦ + Δs}. If the determination in S34 is being affirmative constant is, Delta] P1 is ≠ 0, because it is within the control tolerance range, with respect to building power KP (P0 ± ΔP0) are implemented, the first controller is controlled object controller Is set as (S40).

If S34 is being not constant, the actual power AP1 of the first controller deviates from P0, and, if the divergence power ΔP1 of the first controller exceeds a control tolerance of demand response request (± Delta] s) Is. In this case, since (P0 ± ΔP0) is not realized in the first controller, another controller 24 to be added or replaced is selected for the first controller (S36).

The contents of addition or replacement of another controller 24 in S36 and S38 described above will be described with reference to FIGS. 9 to 11. FIG. 9 is a flowchart showing a procedure for distinguishing addition or replacement. When in FIG. 7 S34 is not constant, the first controller of the offset power ΔP1 = (AP1-BP1) = (AP1-P0) is equal to or a negative value is determined (S46). If the determination of S46 is affirmed, AP1 <P0, and P0 is insufficient only with the first controller. Therefore, additional control is performed to add another controller 24 to the first controller (S48). If the determination of S46 is denied, P1> P0, and the first controller exceeds P0. Therefore, another controller 24 having a baseline power consumption less than the baseline power consumption BP1 of the first controller is used. Replacement Performs replacement control (S50). In the case of additional control, it is sufficient to add one other controller 24, but in the case of replacement control, the baseline power consumption BP of one other controller 24 is less than P0, so two different controllers 24 Replace with a combination of.

If S 72 is denied, the process corresponding to the above S62 to S72 is repeated (S74). Then, in the combination of additional control, when [−Δs ≦ (actual power consumption of the combination) −P0 ≦ + ΔS], the subsequent processing is stopped. Since this corresponds to the affirmation of the determination in S38 in FIG. 7, the additional control ends, the process returns to FIG. 7, and the process proceeds to S40.

When S84 is denied, the dissociated power consumption ΔP2 of the second controller is obtained. ΔP2 = (AP2-BP2) = {AP2- (BP1-ΔP1)}. Therefore, similarly to S46, it is determined whether or not ΔP2 is a negative value (S86). If the determination is affirmed, the process proceeds to the additional control of S48, and another controller is additionally processed to the second controller. If the determination is denied, the fourth controller having the baseline power consumption BP4 corresponding to the power consumption (BP3-ΔP2) obtained by subtracting the deviation power consumption ΔP2 of the second controller from the baseline power consumption BP3 of the third controller is selected. To do. Then, the fourth controller is replaced with the third controller (S88) to form a combination of (second controller + fourth controller) (S90). This combination is called a second combination in replacement control. Then, the actual power consumption AP4 of the fourth controller is referred to (S92). It can be seen that the actual power consumption of the second combination is (AP2 + AP4) (S94). Therefore, it is determined whether or not {(actual power consumption of the second combination) -P0} is within the control allowable range. That is, it is determined whether or not [−Δs ≦ (AP2 + AP4) −P0 ≦ + ΔS] (S96). If the judgment is affirmative, the subsequent processing is stopped. Since this corresponds to the affirmation of the determination in S38 in FIG. 7, the replacement control ends, the process returns to FIG. 7, and the process proceeds to S40.

FIG. 13 further shows a case where the actual power consumption AP1 of the first controller deviates from (P0 ± Δs) as a result of referring to the actual power consumption of the first controller in S30. Since FIG. 13 shows the case of replacement control, {(dissociation power consumption ΔP1) = (AP1-P0)} of the first controller is a positive value, which exceeds the control allowable range (+0.75 kW). The case is shown. Here, the case where the baseline power consumption BP1 of the first controller = P0 (+ 33.3%) is shown as the dissociated power consumption ΔP1. In this case, the actual power consumption AP1 of the first controller is (BP1 = PO = 30 kW) × (100% + 33.3%) = 40 kW, and the divergent power consumption ΔP1 of the first controller is (AP1-P0) =. (+ 10 kW). That is, the reduced power with respect to the building power consumption KP is 10 kW more than P0. In FIG. 13, at t = 0, this reduced excess power (ΔP1 = + 10 kW) is indicated by diagonal lines. Since this reduced excess power (ΔP1 = + 10 kW) exceeds the control allowable range {± (1/2) s} = (± 0.75 kW), the process further proceeds to S76 within the same sub-control cycle. .. In S76, the two controllers with less baseline power BP than the first controller baseline power consumption BP1 as a set, replacing to the first controller (S7 6). One of the two controllers has a second having a baseline power consumption BP2 corresponding to the power consumption (BP1-ΔP1) obtained by subtracting the deviation power consumption ΔP1 of the first controller from the baseline power consumption BP1 of the first controller. It is a controller. The other is a third controller having a baseline power consumption BP3 corresponding to the divergence power consumption ΔP1 of the first controller. The second controller and the third controller are combined into a first combination (S78). Up to this point, the processing performed in the first sub-control cycle.

FIG. 14 is a diagram showing an actual power consumption transition line 78 of the building 12 on a day when the power consumption of the building 12 is not so large in spring or autumn and there is no plan for a demand response request from the electric power company 8. For reference, the alternate long and short dash line 70 also shows the actual power consumption transition line 70 in FIG. The building management device 16 determines the power consumption leveling level 80 in advance, and reduces the power supplied from the power company 8 in the portion where the actual power consumption transition line 78 exceeds the power consumption leveling level 80. I do. In FIG. 14 , the area of the shaded area 82 is the electric energy (kWh) reduced by the power consumption leveling control. In this case as well, the power storage device 34 supplies the equipment 14 that receives the power consumption leveling control with the same amount of power as the reduced power so as not to reduce the convenience of the user. Region 84 hatched enclosed by two-dot chain line is the amount of power the electric storage device 34 is discharged at the same size as the reduced performed power leveling control electrodeposition competence (kWh).

In S134 of FIG. 15, when the power supply of the controller to be controlled is switched for a certain control period, the process proceeds to S136, and it is determined whether or not the power consumption leveling control end time is reached. The power consumption leveling control end time is, for example, 11:00 pm when the power consumption leveling control starts from midnight of the day, assuming that the control time is set every hour. That is, the time when all the processes are completed over the day is the power consumption leveling control end time. If the determination in S136 is denied, the process returns to S120, the actual power consumption AP of each controller 24 is acquired in the next control time, and the above process is repeated. When the judgment at S 1 36 is affirmative, the control is ended power leveling.
