Description

Remote control system, remote control device, gateway, remote control method, control method, and program

[0001] The present disclosure relates to a remote control system, a remote control device, a gateway, a remote control method, a control method, and a program.

[0002] Distributed power sources such as solar power generation systems, storage batteries, and electric vehicles (EVs) are connected to power distribution systems. Remote control systems exist that can contribute to balancing supply and demand by remotely controlling these distributed power sources. In these remote control systems, a remote control device transmits command values ​​to a gateway installed at a consumer's facility using cellular communication such as LTE (Long Term Evolution). The gateway receives these command values ​​and controls the distributed power sources based on the command values.

[0003] Furthermore, Patent Document 1 discloses a power monitoring and control device that controls the power output of a distributed power source based on power information associated with indoor power consumption obtained from a smart meter. When communication with the smart meter fails, this power monitoring and control device controls the power output of the distributed power source based on power information predicted from time information and the like, rather than the power information from the smart meter.

FIG. 2 is a schematic block diagram showing the configuration of a remote server 10 in the same embodiment. FIG. 3 is a schematic block diagram showing the configuration of a gateway 20 in the same embodiment. FIG. 4 is a flowchart illustrating an example of operation of the remote control system 100 in the same embodiment. FIG. 5 is a flowchart illustrating an example of operation of the remote server 10 in the same embodiment. FIG. 6 is a flowchart illustrating an example of operation of the gateway 20 in the same embodiment. FIG. 7 is an explanatory diagram illustrating the hardware configuration of each device according to the embodiment.

[0022] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Fig. 1 is a schematic block diagram showing the configuration of a remote control system 100 according to an embodiment of the present disclosure. The remote control system 100 includes a remote server 10 (remote control device), a gateway 20, and distributed power sources 30. Each of the remote server 10 and the gateway 20 may be realized by one or more computers reading and executing a program.

[0023] The remote server 10 is connected to the gateway 20 via a cellular communication network such as LTE so that they can communicate with each other. The remote server 10 may be connected to multiple gateways 20. The remote server 10 and the gateway 20 may be connected to each other so that they can communicate with each other via a communication means other than a cellular communication network. The gateway 20 is connected to the distributed power sources 30 so that they can communicate with each other via a local area network (LAN) or wireless LAN installed by a consumer. The gateway 20 may be connected to multiple distributed power sources 30.

[0024] The remote server 10 collects performance values ​​related to the distributed power sources 30 via the gateway 20. The remote server 10 also periodically calculates command values ​​(long-period command values) for the distributed power sources 30 and transmits these command values ​​to the gateway 20. These long-period command values ​​are calculated, for example, every minute. When the remote server 10 predicts that communication with the gateway 20 will be interrupted, it calculates long-period command values ​​over multiple periods and transmits these long-period command values ​​to the gateway 20. This allows the gateway 20 to continue controlling the distributed power sources 30 even if communication between the remote server 10 and the gateway 20 is interrupted.

[0025] The gateway 20 acquires actual values ​​related to the distributed power sources 30 and transmits the actual values ​​to the remote server 10. When the gateway 20 receives a long-period command value from the remote server 10, it calculates a command value (short-period command value) based on the long-period command value at a period shorter than the calculation period of the command value, and controls the distributed power sources 30. This period is, for example, 20 seconds. The gateway 20 may use the actual values ​​acquired from the distributed power sources 30 when calculating the short-period command value.

[0026] The distributed power sources 30 are power sources connected to a power distribution system, such as solar power generation, wind power generation, storage batteries, electric vehicles (EVs), and heat pump water heaters, or loads that perform demand response. The distributed power sources 30 are controlled by command values ​​from the gateway 20.

[0027] 2 is a schematic block diagram showing the configuration of the remote server 10 in this embodiment. The remote server 10 includes a communication interruption prediction unit 11, a long-cycle command value calculation unit 12, a transmission unit 13, and a distributed power source DB (Data Base) unit 14. The communication interruption prediction unit 11 predicts whether or not a communication interruption will occur between the gateway 20 and the remote server 10. This prediction may be made based on past communication history or weather information obtained from another system.

[0028] The long-cycle command value calculation unit 12 periodically calculates a long-cycle command value for the distributed power source 30. This cycle is, for example, one minute. The long-cycle command value may be the power at the power receiving point or the charging / discharging power of the distributed power source 30. Furthermore, when the communication interruption prediction unit 11 predicts that a communication interruption will occur, the long-cycle command value calculation unit 12 calculates long-cycle command values ​​over multiple cycles. For example, if the multiple cycles are 10 cycles and the cycle for calculating the long-cycle command values ​​is one minute, when the remote server 10 predicts that a communication interruption will occur, the remote server 10 calculates long-cycle command values ​​over multiple cycles, such as a command value after 0 minutes, a command value after 1 minute, a command value after 2 minutes, ..., and a command value after 10 minutes, and transmits these to the gateway 20. Note that the multiple cycles may be a predetermined number of cycles, or a number of cycles corresponding to the length of the period predicted by the communication interruption prediction unit 11 as the period during which a communication interruption will occur.

[0029] When calculating the long-cycle command value, the long-cycle command value calculation unit 12 may use either or both of the actual values ​​of the distributed power sources 30 stored in the distributed power source DB unit 14 and meteorological information. The actual values ​​of the distributed power sources 30 include, for example, the instantaneous power at the power receiving point, the integrated amount of power, the instantaneous power generation power of the photovoltaic power generation, the integrated amount of power generation, the instantaneous charge / discharge power of the storage battery, and the remaining amount of power stored. The meteorological information includes, for example, the temperature, humidity, the amount of solar radiation, and the wind speed.

[0030] The transmitter 13 transmits the long-cycle command values ​​calculated by the long-cycle command value calculator 12 to the gateway 20. When the communication interruption predictor 11 predicts that a communication interruption will occur, the transmitter 13 transmits the long-cycle command values ​​calculated by the long-cycle command value calculator 12 over multiple periods to the gateway 20.

[0031] The distributed power source DB unit 14 stores the performance values ​​of the distributed power sources 30 acquired via the gateway 20. The distributed power source DB unit 14 may also store weather information.

[0032] 3 is a schematic block diagram showing the configuration of the gateway 20 in this embodiment. The gateway 20 includes a command receiving unit 21, a short-cycle command value calculating unit 22, and a power supply control unit 23. The command receiving unit 21 receives a long-cycle command value from the remote server 10.

[0033] The short-cycle command value calculation unit 22 calculates a short-cycle command value that is shorter than the long-cycle command value based on the long-cycle command value received by the command receiving unit 21. The short cycle is, for example, 20 seconds. The short-cycle command value may be the power at the power receiving point or the charge / discharge power of the distributed power source 30. The short-cycle command value may be different from the long-cycle command value. For example, the long-cycle command value may be the power at the power receiving point, and the short-cycle command value may be the charge / discharge power. Furthermore, short-cycle command values ​​for multiple distributed power sources 30 may be calculated for one long-cycle command value. Furthermore, when the command receiving unit 21 receives long-cycle command values ​​spanning multiple cycles, the short-cycle command value calculation unit 22 calculates the short-cycle command value based on each of the long-cycle command values ​​spanning the multiple cycles.

[0034] For example, if the command receiving unit 21 receives a command value for 0 minutes, a command value for 1 minute, a command value for 2 minutes, ..., a command value for 10 minutes as long-cycle command values, the short-cycle command value calculation unit 22 calculates a short-cycle command value for 0 minutes, a short-cycle command value for 20 seconds, and a short-cycle command value for 40 seconds based on the command value for 0 minutes, calculates a short-cycle command value for 1 minute, a short-cycle command value for 1 minute 20 seconds, and a short-cycle command value for 1 minute 40 seconds based on the command value for 1 minute, calculates a short-cycle command value for 10 minutes, a short-cycle command value for 10 minutes 20 seconds, and a short-cycle command value for 10 minutes 40 seconds based on the command value for 10 minutes. The short-cycle command value calculation unit 22 may use actual values ​​of the distributed power sources 30 when calculating each short-cycle command value. This allows the short-cycle command value calculation unit 22 to correct the next command value if the actual values ​​do not match the command values.

[0035] The power supply control unit 23 transmits the short-cycle command value calculated by the short-cycle command value calculation unit 22 to the distributed power supply 30 .

[0036] 4 is a flowchart illustrating an example of the operation of the remote control system 100 according to this embodiment. First, the remote server 10 predicts a communication interruption (step S1). If no communication interruption is predicted, the remote server 10 calculates a long-cycle command value and transmits it to the gateway 20 (step S2). Next, the gateway 20 receives the long-cycle command value transmitted in step S2 (step S3). Next, the gateway 20 acquires the actual values ​​of the distributed power sources 30 (step S4) and calculates a short-cycle command value using the command value received in step S3 and the actual value acquired in step S4 (step S5). Next, the gateway 20 transmits the command value calculated in step S5 to the distributed power sources 30 (step S6).

[0037] If a communication interruption is predicted in step S1, the remote server 10 calculates long-cycle command values ​​for multiple periods and transmits them to the gateway 20 (step S7). The gateway 20 then receives the long-cycle command values ​​for multiple periods transmitted in step S7 (step S8). The gateway 20 then acquires the actual values ​​of the distributed power sources 30 (step S9) and calculates short-cycle command values ​​using the command values ​​received in step S8 and the actual values ​​acquired in step S9 (step S10). The gateway 20 then transmits the command values ​​calculated in step S10 to the distributed power sources 30 (step S11).

[0038] FIG. 5 is a flowchart illustrating an example of the operation of the remote server 10 in this embodiment. First, the communication interruption prediction unit 11 predicts whether a communication interruption will occur (step Sa1). If a communication interruption has occurred (step Sa2-Y), the long-cycle command value calculation unit 12 calculates a long-cycle command value spanning multiple periods (step Sa3). Next, the transmission unit 13 transmits the long-cycle command value spanning multiple periods calculated in step Sa3 to the gateway 20 (step Sa4), and the process returns to step Sa1. Also, if the prediction result in step Sa1 does not indicate an occurrence (step Sa2-N), the long-cycle command value calculation unit 12 calculates a long-cycle command value (step Sa5). The command value calculated here is for only one period. Next, the transmission unit 13 transmits the long-cycle command value calculated in step Sa5 to the gateway 20 (step Sa6), and the process returns to step Sa1.

[0039] 6 is a flowchart illustrating an example of the operation of the gateway 20 in this embodiment. First, the command receiving unit 21 receives commands from the remote server 10 (step Sb1). If the received command contents in step Sb1 include multiple long-period command values ​​(step Sb2-Y), the gateway 20 repeats steps Sb4 to Sb9 for each long-period period for the multiple periods (steps Sb3 and Sb11), and returns to step Sb1 when the repetition is complete.

[0040] In step Sb4, one command value is acquired from the multiple long-cycle command values. The acquired command value is the one corresponding to the relevant repetition among the multiple long-cycle command values. For example, for the first repetition, it is the command value after 0 minutes, and for the second repetition, it is the command value after 1 minute. Next, the gateway 20 repeats steps Sb6 to Sb8 for one long cycle for each short cycle period (steps Sb5 and Sb9). For example, if the long cycle is 1 minute and the short cycle is 20 seconds, this repetition is 3 times, which is 1 minute divided by 20 seconds.

[0041] In step Sb6, the gateway 20 acquires the actual values ​​of the distributed power sources 30. Next, the gateway 20 calculates a short-cycle command value based on the long-cycle command value acquired in step Sb4 and the actual values ​​acquired in step Sb6 (step Sb7). Next, the gateway 20 transmits the short-cycle command value calculated in step Sb7 to the distributed power sources 30 (step Sb8).

[0042] On the other hand, if the received content of step Sb1 does not include multiple long-cycle command values, i.e., if there is only one long-cycle command value (step Sb2-N), the gateway 20 acquires the long-cycle command value (step Sb12). Next, the gateway 20 repeats steps Sb14 to Sb16 for one long cycle for each short cycle period (steps Sb13 and Sb17), and returns to step Sb1 when the repetition is complete. This repetition is similar to the repetition of steps Sb5 and Sb9. For example, if the long cycle is one minute and the short cycle is 20 seconds, the number of repetitions is three, which is one minute divided by 20 seconds.

[0043] In step Sb14, the gateway 20 acquires the actual values ​​of the distributed power sources 30. Next, the gateway 20 calculates a short-cycle command value based on the long-cycle command value acquired in step Sb12 and the actual values ​​acquired in step Sb14 (step Sb15). Next, the gateway 20 transmits the short-cycle command value calculated in step Sb15 to the distributed power sources 30 (step Sb16).
