JP 2007-1224797 A

  However, in the method of Patent Document 1, for example, when a gust blows in wind power generation, the power generated by the wind power generation increases, and thus the power transmitted to the power source may change. Therefore, power that cannot be charged by the storage battery may be transmitted to the storage battery due to a change in power or the like. And when the electric power which cannot charge a storage battery is transmitted to a storage battery, the installation which concerns on a storage battery may stop by control. Therefore, the entire autonomous operation control system may stop. Therefore, there is a possibility that the problem that the operation rate of the self-sustained operation control system becomes low may occur.

  One aspect of the present invention has been made in view of such a problem, and an object thereof is to increase the operation rate of the autonomous operation control system.

If the value is equal to or higher than the first upper limit value or the measured value is equal to or lower than the first lower limit value indicating the lower limit of the first range, the frequency related to the alternating current is changed to the storage battery system, and the measurement is performed. When the value is equal to or greater than a second upper limit value indicating the upper limit of the second range other than the first range, or the measured value is equal to or less than a second lower limit value indicating the lower limit of the second range, the power generation Equipment And a control unit for limiting the serial transmission.

Specifically, the bidirectional conversion device 111 converts an alternating current AC transmitted from the power generation facility to the storage battery system 11 via the bus 14 into a direct current DC charged in the storage battery 112.

  Further, the bidirectional conversion device 111 converts the direct current DC output from the storage battery 112 into an alternating current AC. Note that the storage battery system 11 can discharge the alternating current AC to the bus bar 14 by the bidirectional conversion device 111 converting the direct current DC into the alternating current AC.

  The storage battery 112 charges the direct current DC converted by the bidirectional conversion device 111. Moreover, the storage battery 112 discharges the direct current to charge.

  The control device 113 controls the bidirectional conversion device 111 based on the command data 3 from the autonomous operation control device 10. Further, the control device 113 measures the measurement values relating to the alternating current AC, the direct current DC, and the storage battery 112 by various sensors, and the control device 113 sends the measurement values to the autonomous operation control device 10 as measurement data 2.

  The measured value is, for example, power ACP related to AC current AC, voltage ACV related to AC current AC, current ACI related to AC current AC, or the like. Furthermore, the measured value may be, for example, the power DCP related to the direct current DC, the voltage DCV related to the direct current DC, or the current DCI related to the direct current DC. Furthermore, the measured value is, for example, a charge rate (State Of Charge) SOC related to the storage battery 112 or a temperature T related to the storage battery 112.

  In the measurement value, the power related to each alternating current may be obtained by calculation based on each current, each voltage, and the like. Furthermore, the power ACP related to the alternating current AC is preferably an effective power calculated from the voltage ACV related to the alternating current AC and the current ACI related to the alternating current AC.

  In the measurement value, the charging rate SOC related to the storage battery 112 may be obtained by calculation based on the current DCI related to the direct current DC or the like.

  Furthermore, the operation state of the storage battery system 11 is notified to the independent operation control device 10 by the measurement data 2 or the like. Furthermore, the self-sustained operation control apparatus 10 may perform calculation of measured values, calculation of active power, and the like.

  FIG. 4 is a functional block diagram illustrating an example of a functional configuration of a control device included in the storage battery system according to the embodiment of the present invention. Specifically, the control device 113 includes a droop control unit 1131, a frequency control unit 1132, a voltage command unit 1133, a voltage calculation unit 1134, and a voltage control unit 1135.

  The droop control unit 1131 outputs the voltage adjustment value dV and the frequency adjustment value df so as to obtain a so-called droop characteristic. Specifically, the droop control unit 1131 includes a voltage regulator and a frequency regulator. Further, the droop control unit 1131 outputs a frequency adjustment value df corresponding to the effective current component of the current ACI related to the AC current AC to the frequency control unit 1132 by the frequency adjuster. In addition, the droop control unit 1131 outputs a voltage adjustment value dV corresponding to the reactive current component of the current ACI related to the alternating current AC to the voltage control unit 1135 by the voltage regulator.

  The frequency control unit 1132 calculates an internal frequency f for operating the storage battery system, and outputs it to the voltage command unit 1133. Specifically, the frequency control unit 1132 outputs, for example, an a-phase reference signal and a c-phase reference signal whose frequency is the internal frequency f to the voltage command unit 1133. Furthermore, the frequency control unit 1132 includes a first adder A1 and a second adder A2. Note that the frequency control unit 1132 may include a VCO (Voltage Controlled Oscillator). First, the frequency control unit 1132 adds the frequency adjustment value df output from the droop control unit 1131 and the reference frequency f0 by the first adder A1. The reference frequency f0 is a frequency set in advance in the frequency control unit 1132, and is 50 Hz, for example. Next, the frequency control unit 1132 adds the frequency correction value Δf input from the autonomous operation control device 10 and the output value of the first adder A1 by the second adder A2, and calculates the internal frequency f. To do. The frequency correction value Δf is input by command data 3 (see FIG. 3), for example.

  When the direct current DC is discharged by the storage battery 112, the value of the internal frequency f decreases as the effective current component of the alternating current AC increases. On the other hand, when the direct current DC is charged by the storage battery 112, the value of the internal frequency f increases as the effective current component of the alternating current AC increases.

  The VCO is a voltage control oscillator, and the frequency control unit 1132 outputs an a-phase reference signal and a c-phase reference signal based on the internal frequency f by the VCO. For example, when the reference phase angle is θ, the a-phase reference signal is a signal having a waveform of cos θ, and the c-phase reference signal is a signal having a waveform of cos (θ + 2π / 3).

The voltage calculation unit 1134 calculates the voltage of the effective current component and the voltage of the reactive current component of the voltage ACV related to the alternating current AC. Next, the voltage calculation unit 1134 attenuates harmonics and the like included in the voltage of the active current component and the voltage of the reactive current component using a filter circuit or the like. Subsequently, the voltage calculation unit 1134 calculates a peak value | Vn | based on the voltage of the active current component and the voltage of the reactive current component. Specifically, assuming that the effective current component voltage is Vd and the reactive current component voltage is Vq, the peak value | Vn | is calculated by, for example, the peak value | Vn | = √ (Vd ² + Vq ² ). Subsequently, the voltage calculation unit 1134 outputs the peak value | Vn | to the voltage control unit 1135.

  The voltage control unit 1135, for example, the voltage correction value ΔV calculated based on the voltage adjustment value dV and the charging rate SOC (see FIG. 3), the peak value | Vn |, and the reference value of the voltage ACV related to the alternating current AC Based on the above, the voltage deviation dVn is calculated. Next, the voltage control unit 1135 outputs the calculated voltage deviation dVn to the voltage command unit 1133.

  The voltage command unit 1133 outputs the voltage deviation dVn and the internal frequency f to the bidirectional conversion device 111 using, for example, a PWM (Pulse Width Modulation) signal.

  The bidirectional conversion device 111 converts the alternating current so that the frequency of the voltage ACV related to the alternating current AC becomes the internal frequency f. Furthermore, the bidirectional conversion device 111 converts the alternating current so that the amplitude of the voltage ACV related to the alternating current AC is multiplied by the voltage deviation dVn.

<< Example of Calculation of Output Limit Value and Process Example Based on Measurement Value (Step S200) >>
The independent operation control device calculates an output limit value P. Further, the autonomous operation control apparatus performs processing based on the measurement value acquired in the process of calculating the output limit value P (step S200).

  FIG. 6 is a flowchart illustrating a calculation example of the output limit value and a processing example based on the measurement value according to the embodiment of the present invention. Note that the process of step S200 illustrated in FIG. 5 is, for example, the process illustrated in FIG. Hereinafter, the case where the output limit value P is calculated by the process shown in FIG. 6 will be described as an example. In FIG. 6, the maximum power that can be transmitted and generated by the power generation facility 13 (see FIG. 1) is the output limit value P, the value for counting the storage battery system 11 (see FIG. 1) is the counter value k, and each storage battery system. The maximum power that can be charged by each of the storage batteries 112 (see FIG. 3) included in each of the 11 is defined as maximum power A. Note that the maximum power A may differ for each storage battery system 11 depending on the specifications of each storage battery 112 and the like.

  First, in FIG. 6, the autonomous operation control device initializes each variable (step S210). Specifically, in step S210, the independent operation control device inputs, for example, “0” for the output limit value P, “1” for the counter value k, and “0” for the maximum power A, respectively.

  Next, the autonomous operation control device acquires the operation state of the storage battery system 11 based on the measurement data 2 (see FIG. 3) and the like. Subsequently, the independent operation control device determines whether or not the k-th unit of the storage battery system is in operation based on the measurement data 2 or the like (step S220). Specifically, for example, when the counter value k is “1”, if the storage battery system of Unit 1 is in operation, the autonomous operation control device determines that it is in operation (YES in step S220). ). On the other hand, when the counter value k is “1”, when the storage battery system of the first unit is not in operation, the autonomous operation control device determines that it is not in operation (NO in step S220).

  When the autonomous operation control device determines that the k-th unit of the storage battery system is in operation, the autonomous operation control device proceeds to step S230. On the other hand, when the autonomous operation control device determines that the k-th unit of the storage battery system is not operating, the autonomous operation control device proceeds to step S280.

  In each step from step S230 to step S250 described below, based on the measured value related to the storage battery system 11 of the k-th unit corresponding to the counter value k, the autonomous operation control device is in which range the measured value is. to decide. Specifically, first, the self-sustained operation control apparatus acquires a measurement value related to the storage battery system 11 corresponding to the counter value k from the measurement data 2 or the like. Next, in each step from step S230 to step S250, the self-sustained operation control device determines which value is within a predetermined range of the measurement value.

  FIG. 7 is a table showing an example of a range of measurement values according to an embodiment of the present invention. For example, each range is determined by each upper limit value and each lower limit value shown in the table TB. Hereinafter, in FIG. 7, the measured values are the power ACP related to the alternating current AC (see FIG. 3), the current DCI related to the direct current DC (see FIG. 3), the voltage DCV related to the direct current DC, the charging rate SOC, and the temperature. The case of T will be described as an example.

  The range is determined by, for example, “the lower limit value of the first range” and “the upper limit value of the first range”. Hereinafter, the range determined by the “lower limit value of the first range” and the “upper limit value of the first range” is referred to as the first range. For example, the first range related to the power ACP related to the alternating current AC determined by the table TB is a range of “−500” to “500”. Further, a value equal to or higher than the upper limit value of the first range based on the table TB is a value equal to or greater than “500”. Furthermore, the value below the lower limit value of the first range based on the table TB is a value below “−500”. The first range is a range determined by the table TB for each “measured value type”.

  Further, the range is determined by, for example, “the lower limit value of the second range” and “the upper limit value of the second range”. Hereinafter, the range determined by the “lower limit value of the second range” and the “upper limit value of the second range” is referred to as the second range. For example, the second range related to the power ACP related to the alternating current AC determined by the table TB is a range of “−510” to “510”. Further, a value equal to or higher than the upper limit value of the second range based on the table TB is a value equal to or greater than “510”. Furthermore, the value below the lower limit of the second range based on the table TB is a value below “−510”. The second range is a range determined by the table TB for each “measured value type”, like the first range.

  Furthermore, the range is determined by, for example, “the lower limit value of the third range” and “the upper limit value of the third range”. Hereinafter, the range determined by the “lower limit value of the third range” and the “upper limit value of the third range” is referred to as the third range. For example, the third range related to the power ACP related to the alternating current AC determined by the table TB is a range of “−520” to “520”. Further, a value equal to or higher than the upper limit value of the third range based on the table TB is a value equal to or greater than “520”. Furthermore, the value below the lower limit value of the third range based on the table TB is a value below “−520”. The third range is a range determined by the table TB for each “measured value type”, like the first range.

  The first upper limit value is, for example, “upper limit value of the first range” in FIG. 7, and the first lower limit value is, for example, “lower limit value of the first range” in FIG. 7. The second upper limit value is, for example, “upper limit value of the second range” in FIG. 7, and the second lower limit value is, for example, “lower limit value of the second range” in FIG. 7. Further, the third upper limit value is, for example, “upper limit value of the third range” in FIG. 7, and the third lower limit value is, for example, “lower limit value of the third range” in FIG. 7.

  Each value shown in the table TB may be set based on the specification of the storage battery 112 (see FIG. 3). Furthermore, when there are a plurality of storage battery systems, different tables TB may be input for each storage battery system, and different ranges may be determined for each storage battery system.

  Hereinafter, the case where the measured value is the power ACP related to the alternating current AC will be described as an example. The electric power ACP related to the alternating current AC corresponds to the “electric power ACP related to the alternating current” in the “type of measurement values” shown in FIG.

  FIG. 8 is an overall configuration diagram illustrating an example of an overall configuration of a self-sustained operation control system in which a measurement value in one embodiment of the present invention is electric power related to an alternating current. Hereinafter, the independent operation control system 1 shown in FIG. 8 will be described as an example. Specifically, the autonomous operation control system 1 shown in FIG. 8 includes one wind power generation facility as the power generation facility 13, and includes three storage battery systems of the storage battery system 11A, the storage battery system 11B, and the storage battery system 11C (n = 3) This is an example. Furthermore, a measured value is each shown by measurement data etc. for every storage battery system. Further, in the autonomous operation control system 1, the measurement value related to the storage battery system 11A of the first unit is measured value 2A, the measurement value related to the storage battery system 11B of the second unit is measured value 2B, and the measurement value related to the storage battery system 11C of the third unit Is the measured value 2C.

  In addition, the storage battery system corresponding to the counter value k (see FIG. 6) of “1” (k = 1) is the storage battery system 11A of Unit 1 shown in FIG. Similarly, the storage battery system corresponding to the counter value k “2” (k = 2) is the storage battery system 11B of the second unit, and the storage battery system corresponding to the counter value k “3” (k = 3). Is the storage battery system 11C of No. 3.

  In addition, in each storage battery system shown in FIG. 8, the maximum power A (see FIG. 6) is “500”, and the maximum power A is the same.

  FIG. 8 shows a case where the power generation facility 13 generates power ACP related to 1500 kW AC current AC. In this case, the electric power related to the alternating current generated by the power generation facility 13 is distributed and transmitted to the load facility 12 and each storage battery system by the alternating current. Specifically, in the independent operation control system 1, it is assumed that an alternating current is transmitted to each storage battery system so that 150 kW out of 1500 kW is transmitted to the load facility 12. In addition, although each alternating current transmitted to each storage battery system is transmitted so that the power related to each alternating current is equal, as shown in FIG. 8, the power related to each alternating current varies. May occur. Hereinafter, as illustrated in FIG. 8, an example will be described in which there is variation in the power related to each alternating current transmitted to each storage battery system.

  In addition, the dispersion | variation in the electric power which concerns on each alternating current determines the share of the electric power which concerns on the alternating current 111 which each storage battery system each has (refer FIG. 3) charges with respect to the alternating current to charge by slope (proportional) control. This occurs due to variations related to characteristics such as impedance related to each transformer and variations related to characteristics of transmission and distribution lines.

≪Example of processing according to third range (Step S230 and Step S231) ≫
Returning to FIG. 6, the independent operation control device determines whether or not the measured value is within the third range (step S <b> 230). Specifically, in step S230, the self-sustained operation control device first acquires a measurement value related to the storage battery system corresponding to the counter value k. Next, in step S230, the independent operation control device compares the measured value with the “upper limit value of the third range” shown in the table TB (see FIG. 7). Furthermore, in step S230, the independent operation control device compares the measured value with the “lower limit value of the third range” shown in the table TB.

  That is, in step S230, when the independent operation control device determines that the measured value is either a value greater than or equal to the third upper limit value or a value less than or equal to the third lower limit value (NO in step S230), the autonomous operation control device The process proceeds to step S231. On the other hand, when the independent operation control device determines in step S230 that the measured value is not a value equal to or greater than the third upper limit value and the measured value is not equal to or smaller than the third lower limit value (YES in step S230), the autonomous operation control is performed. The apparatus goes to step S240.

  For example, in the storage battery system 11A of Unit 1 shown in FIG. 8 (when the counter value k = 1), the measurement value is “445” because the measurement value is 2A. In this case, the measured value 2A is not a value equal to or greater than “520” which is the “upper limit value of the third range” shown in the table TB. Furthermore, the measured value 2A is not a value equal to or less than “−520” that is the “lower limit value of the third range” shown in the table TB. That is, the measured value 2A is a value within the third range. Therefore, the independent operation control device determines that the measured value 2A is a value within the third range (YES in step S230).

  On the other hand, when the independent operation control device determines that the measured value is not within the third range (NO in step S230), the independent operation control device restricts the operation of the storage battery system (step S231). Specifically, in step S231, the independent operation control device stops, for example, each storage battery system whose measured value is not within the third range. That is, the process for limiting the operation of the storage battery system is a process for stopping the storage battery system, for example.

  FIG. 9 is a logic circuit diagram showing an example of processing related to the third range by the self-sustained operation control apparatus according to the embodiment of the present invention. FIG. 9 is a diagram illustrating an example of the processing in step S230 and step S231. Further, the processing in step S230 corresponds to the processing by the determination circuit 4 in FIG.

  Specifically, the independent operation control device compares the measured value with the “upper limit value of the third range” shown in the table TB (see FIG. 7) by the determination circuit 4. Furthermore, the independent operation control device uses the determination circuit 4 to compare the measured value with the “lower limit value of the third range” shown in the table TB. In addition, the independent operation control device outputs, as a signal, a result of determining whether or not the measured value is a value within the third range by the “NOR” logic circuit by the determination circuit 4 (step S230).

  Next, the autonomous operation control device outputs a signal for controlling the operation of the storage battery system by the output circuit 5 based on the signal indicating the output result of the determination circuit 4 and the control signal for the storage battery system. The output circuit 5 is, for example, an “AND” logic circuit connected as shown in FIG. Specifically, the output circuit 5 outputs either a signal for continuing the operation of the storage battery system (“1” in FIG. 9) or a signal for stopping the operation of the storage battery system (“0” in FIG. 9). To do. In addition, the process which a self-sustained operation control apparatus outputs the signal which stops the driving | operation of a storage battery system is an example of the process of step S231.

  When electric power related to a large alternating current is transmitted to the storage battery system, the self-sustained operation control device limits the operation of the storage battery system by the process of step S231. That is, the self-sustained operation control apparatus can protect the storage battery system from electric power related to a large alternating current by the process of step S231. Therefore, by restricting the operation of the storage battery system, the independent operation control device can increase the safety of the storage battery system.

≪Example of processing according to second range (step S240 and step S241) ≫
Returning to FIG. 6, the independent operation control device determines whether or not the measured value is within the second range (step S240). Specifically, in step S240, the independent operation control device compares the measured value with the “upper limit value of the second range” shown in the table TB (see FIG. 7). Further, in step S240, the independent operation control device compares the measured value with the “lower limit value of the second range” shown in the table TB.

  That is, in step S240, when the autonomous driving control device determines that the measured value is either a value greater than or equal to the second upper limit value or a value less than or equal to the second lower limit value (NO in step S240), the autonomous driving control device The process proceeds to step S241. On the other hand, in step S240, when the independent operation control device determines that the measured value is not a value equal to or greater than the second upper limit value and the measured value is not equal to or smaller than the second lower limit value (YES in step S240), the autonomous operation control is performed. The apparatus goes to step S250.

  For example, in the storage battery system 11A of Unit 1 shown in FIG. 8 (when the counter value k = 1 in FIG. 6), the measurement value is “445” because the measurement value is 2A. In this case, the measured value 2A is not a value equal to or greater than “510” which is the “upper limit value of the second range” shown in the table TB (see FIG. 7). Furthermore, the measured value 2A is not a value equal to or less than “−510” which is the “lower limit value of the second range” shown in the table TB. That is, the measured value 2A is a value within the second range. Therefore, the independent operation control device determines that the measured value 2A is a value within the second range (YES in step S240).

  On the other hand, when the autonomous operation control device determines that the measured value is not within the second range (NO in step S240), the autonomous operation control device restricts power transmission to the power generation facility (step S241). Specifically, in step S241, the self-sustained operation control device, for example, stops power generation by the power generation facility by sending a stop signal to the power generation facility, and releases the power generation facility by sending an operation signal to a circuit breaker or the like. To line up.

  FIG. 10 is an overall configuration diagram illustrating an example of processing related to the second range by the autonomous operation control apparatus according to the embodiment of the present invention. In the following, FIG. 10 will be described with an example of a self-sustaining operation control system 1 similar to the self-sustaining operation control system shown in FIG. Therefore, description of the independent operation control system 1 is omitted.

  The case where the independent operation control device 10 determines that the measured value is not within the second range (NO in step S240 in FIG. 6) is, for example, the case illustrated in FIG. Specifically, in FIG. 10A, when the power generation facility 13 is a wind power generation facility, when a gust or the like blows, the power generation facility 13 generates electric power related to an alternating current larger than that shown in FIG. Power transmission. Note that, as shown in FIG. 10A, the phenomenon in which the power related to the large alternating current is generated temporarily by the power generation facility 13 is a so-called overshoot phenomenon. Hereinafter, FIG. 10 will be described by taking as an example a case where the power related to each alternating current is as shown in FIG. 10A due to the overshoot phenomenon.

  In FIG. 10A, the electric power ACP related to the alternating current AC transmitted to each storage battery system is 515 kW, respectively. Therefore, in the power ACP related to the alternating current AC, the measured value is a value of “510” or more, which is the “upper limit value of the second range”, from the table TB (see FIG. 7). Therefore, in the electric power ACP related to the AC current AC to be transmitted, the measured value is determined by the self-sustaining operation control device 10 to be not within the second range (NO in step S240 in FIG. 6).

  Next, in step S241 (see FIG. 6), the autonomous operation control device 10 stops the power generation by the power generation facility 13. For example, in step S241, the independent operation control device 10 sends a signal or the like for stopping power generation to the power generation facility 13. Subsequently, when a signal for stopping power generation is sent, the power generation facility 13 stops power generation. Further, as shown in FIG. 10B, the self-sustained operation control device 10 disconnects the connection between the power generation facility 13, each storage battery system, and the load facility 12 by using a circuit breaker or the like included in the power generation facility 13. Is disconnected.

  When power transmission related to the alternating current from the power generation facility 13 is restricted in step S241, the storage battery system 11A, the storage battery system 11B, and the storage battery system 11C each discharge an alternating current of 50 kW of power. Next, the alternating current discharged from each storage battery system is transmitted to the load facility 12. Therefore, even if power transmission related to the alternating current is restricted from the power generation facility 13 to the load facility 12, the power related to the alternating current consumed by the load facility 12, as shown in FIG. 12 is transmitted. Therefore, the self-sustained operation control system 1 can lengthen the time during which the load facility 12 is transmitting power related to a constant alternating current consumed by the load facility 12. Therefore, the autonomous operation control device 10 can increase the operation rate of the autonomous operation control system 1 by limiting the power transmission from the power generation facility 13.

≪Example of processing according to first range (step S250 and step S251) ≫
Returning to FIG. 6, the independent operation control device determines whether or not the measured value is within the first range (step S250). Specifically, in step S250, the independent operation control device compares the measured value with an “upper limit value of the first range” shown in the table TB (see FIG. 7). Further, in step S250, the independent operation control device compares the measured value with the “lower limit value of the first range” shown in the table TB.

  That is, in step S250, when the autonomous driving control apparatus determines that the measured value is either a value equal to or higher than the first upper limit value or a value equal to or smaller than the first lower limit value (NO in step S250), the autonomous driving control apparatus The process proceeds to step S251. On the other hand, in step S250, when the independent operation control device determines that the measured value is not a value equal to or greater than the first upper limit value and the measured value is not equal to or less than the first lower limit value (YES in step S250), the autonomous operation control is performed. The apparatus goes to step S260.

  For example, in the storage battery system 11A of Unit 1 shown in FIG. 8 (when the counter value k = 1 in FIG. 6), the measurement value is “445” because the measurement value is 2A. Therefore, the measured value 2A is not a value equal to or greater than “500” that is the “upper limit value of the first range” shown in the table TB. Furthermore, the measured value 2A is not a value equal to or less than “−500” that is the “lower limit value of the first range” shown in the table TB. That is, the measured value 2A is a value within the first range. Therefore, the autonomous operation control apparatus determines that the measured value 2A is a value within the first range (YES in step S250).

  On the other hand, when the autonomous operation control device determines that the measured value is not within the first range (NO in step S250), the autonomous operation control device causes the storage battery system to change the frequency related to the alternating current (step S251). In addition, the frequency concerning an alternating current is the internal frequency f shown in FIG. 4, for example. Hereinafter, a case where the frequency related to the alternating current is the internal frequency f will be described as an example.

  FIG. 11 is an overall configuration diagram illustrating an example of processing related to the first range by the autonomous operation control apparatus according to the embodiment of the present invention. In the following, FIG. 11 will be described with an example of a self-sustaining operation control system 1 similar to the self-sustaining operation control system shown in FIG. Therefore, description of the independent operation control system 1 is omitted.

  When the independent operation control device 10 determines that the measured value is not within the first range (NO in step S250 in FIG. 6), for example, the storage battery system 11C shown in FIG. 11A (counter value k = 3 in FIG. 6). ). Specifically, when the power generation facility 13 is a wind power generation facility, when an overshoot phenomenon or the like similar to that in FIG. 10A occurs, the power generation facility 13 is shown in FIG. 8 as shown in FIG. Electric power is generated and transmitted according to a larger alternating current than shown. Hereinafter, the case where the power related to each alternating current is as shown in FIG. 11A due to the overshoot phenomenon will be described as an example.

  For example, in FIG. 11 (A), the electric power concerning the alternating current transmitted to 11 A of storage battery systems and the storage battery system 11B is 460 kW, respectively. On the other hand, the electric power related to the alternating current transmitted to the storage battery system 11C is 505 kW due to variations and the like. That is, in FIG. 11A, the measured value related to the storage battery system 11C is a value equal to or greater than “500” that is the “upper limit value of the first range” from the table TB (see FIG. 7). Accordingly, the measured value related to the storage battery system 11C is determined by the self-sustained operation control device 10 to be not within the first range (NO in step S250 when the counter value k = 3 in FIG. 6). Next, the independent operation control device 10 causes the storage battery system 11C to change the internal frequency f (see FIG. 4) (step S251 (see FIG. 6)).

  Specifically, in step S251, the autonomous operation control apparatus 10 changes the internal frequency f to the storage battery system 11C by sending the frequency correction value Δf to the storage battery system 11C that changes the internal frequency f. That is, the self-sustaining operation control device 10 can change the electric power related to the alternating current transmitted to the storage battery system 11C by changing the internal frequency f to the storage battery system 11C. A method for calculating the frequency correction value Δf will be described later.

  Further, when the power related to the alternating current transmitted to the storage battery system 11C is changed, a part of the power related to the alternating current transmitted to the storage battery system 11C shown in FIG. 11A is stored in the storage battery system 11A and the storage battery system. 11B is transmitted. For this reason, as shown in FIG. 11 (B), the autonomous operation control device 10 equalizes the power related to the alternating current transmitted to the storage battery system 11A, the storage battery system 11B, and the storage battery system 11C, and the first range. Can be a value within Note that the power related to the AC current to be transmitted may not be equal. That is, the autonomous operation control device 10 can change the power related to the alternating current transmitted to each storage battery system to the power within the first range by changing the internal frequency f to the storage battery system.

  Therefore, the self-sustained operation control device 10 can lengthen the time for transmitting the power related to the constant alternating current consumed by the load facility 12 to the load facility 12. Therefore, the independent operation control device 10 can increase the operating rate of the independent operation control system 1 by changing the internal battery frequency f.

  In addition, when the process of step S251 (refer FIG. 6) is performed, the autonomous operation control apparatus 10 may send the command which makes the electric power generation equipment 13 reduce an output limit value. Hereinafter, as illustrated in FIG. 11C, the case where the power generation facility 13 generates power related to an alternating current of 1665 kW will be described as an example. Specifically, for example, when electric power related to an alternating current of 1665 kW is generated, even if the internal frequency f related to the storage battery system 11C is changed, power is transmitted to each storage battery system as shown in FIG. The electric power related to the alternating current does not fall within the first range. In response to this, the independent operation control device 10 sends a command to the power generation facility 13 to lower the output limit value.

  Specifically, in the overall process illustrated in FIG. 6, when the process of step S251 is performed, the autonomous operation control apparatus 10 does not perform the processes of steps S260 and S270. Therefore, in step S270, the maximum power A related to the storage battery system that is the target of the process in step S251 is not added. For example, in the case illustrated in FIG. 11C, “500” that is the maximum power A of the storage battery system 11C is not added. Therefore, in step S300 (see FIG. 5), the autonomous operation control device 10 sets the output limit value to “1150”. Is sent to the power generation facility 13.

  Next, when a command to lower the output limit value to “1150” is sent from the self-sustained operation control device 10 to the power generation facility 13 in step S300, the power related to the alternating current generated by the power generation facility 13 is as shown in FIG. As shown in FIG. As a result, as shown in FIG. 11 (D), the autonomous operation control device 10 equalizes the electric power related to the alternating current transmitted to the storage battery system 11A, the storage battery system 11B, and the storage battery system 11C, and the first range. Can be a value within Note that the power related to the AC current to be transmitted may not be equal. Therefore, the self-sustained operation control device 10 can lengthen the time for transmitting the power related to the constant alternating current consumed by the load facility 12 to the load facility 12. Therefore, the autonomous operation control device 10 can increase the operating rate of the autonomous operation control system 1 by sending a command to the power generation facility 13 to lower the output limit value.

<< Calculation example of frequency correction value Δf >>
Hereinafter, a method of calculating the frequency correction value Δf will be described for each type of measurement value.

  FIG. 12 is a control block diagram illustrating an example of a method for calculating a frequency correction value when the measurement value according to an embodiment of the present invention is power related to an alternating current. In addition, FIG. 12 shows an example of a calculation method for the upper limit value side among the calculation methods of the frequency correction value when the measured value is power related to an alternating current. That is, FIG. 12 is an example of a calculation method used when the measured value is a positive value.

  For example, as shown in the figure, the autonomous operation control device compares the measured value with the first upper limit value and calculates the difference value. Next, the self-sustained operation control device calculates a correction value corresponding to the difference value using a frequency adjuster or the like. The calculated correction value is adjusted so as to be a value within a predetermined upper limit value and lower limit value by an upper / lower limiter or the like. Subsequently, the calculated correction value is multiplied by a corresponding coefficient depending on whether the measured value is a positive value or a negative value. Further, the multiplied correction value is inverted in sign to become a power frequency correction value Δfv. That is, when the measured value is power related to an alternating current, the frequency correction value Δfv for power is calculated as the frequency correction value Δf by a calculation method shown in the figure.

  Specifically, as shown in FIG. 11 (A), when the power related to the alternating current transmitted to the storage battery system has a value equal to or higher than the first upper limit value, the autonomous operation control device has a positive power frequency. The correction value Δfv is sent to the storage battery system as the frequency correction value Δf. Thereby, the storage battery system can change the internal frequency f (refer FIG. 4) with the frequency correction value (DELTA) f. Therefore, the self-sustained operation control device can reduce the electric power related to the alternating current transmitted to the storage battery system by causing the storage battery system to change the internal frequency f.

  FIG. 13 is a control block diagram illustrating an example of a method of calculating a frequency correction value when the measured value according to an embodiment of the present invention is a current related to a direct current. FIG. 13 shows an example of the calculation method for the upper limit value side among the calculation methods of the frequency correction value when the measurement value is a current related to a direct current. That is, FIG. 13 is an example of a calculation method used when the measured value is a positive value.

  For example, as shown in the figure, the autonomous operation control device compares the measured value with the first upper limit value and calculates the difference value. Next, the self-sustained operation control device calculates a correction value corresponding to the difference value using a frequency adjuster or the like. The calculated correction value is adjusted by an upper / lower limiter or the like so as to be a value within a predetermined upper limit value and lower limit value. Subsequently, the calculated correction value is multiplied by a corresponding coefficient depending on whether the measured value is a positive value or a negative value. Further, the multiplied correction value is inverted in sign to become a current frequency correction value Δfc related to the direct current. That is, when the measured value is a current related to a direct current, a current frequency correction value Δfc related to the direct current is calculated as the frequency correction value Δf by a calculation method shown in the figure.

  Specifically, when the current related to the direct current converted from the alternating current transmitted to the storage battery system has a value greater than or equal to the first upper limit value, the autonomous operation control device is for the current related to the direct current that becomes a positive value. The frequency correction value Δfc is sent to the storage battery system as the frequency correction value Δf. Thereby, the storage battery system can change the internal frequency f (refer FIG. 4) with the frequency correction value (DELTA) f. Therefore, the self-sustained operation control device can reduce the electric power related to the alternating current transmitted to the storage battery system by causing the storage battery system to change the internal frequency f. Therefore, the self-sustained operation control device can reduce the current related to the direct current by reducing the power related to the alternating current transmitted to the storage battery system.

  FIG. 14 is a control block diagram illustrating an example of a method for calculating a frequency correction value when the measured value according to an embodiment of the present invention is a voltage related to a direct current. FIG. 14 shows an example of a calculation method for the upper limit value among the calculation methods of the frequency correction value when the measured value is a voltage related to a direct current. That is, FIG. 14 is an example of a calculation method used when the measured value is a positive value.

  For example, as shown in the figure, the autonomous operation control device compares the measured value with the first upper limit value and calculates the difference value. Next, the self-sustained operation control device calculates a correction value corresponding to the difference value using a frequency adjuster or the like. The calculated correction value is adjusted by an upper / lower limiter or the like so as to be a value within a predetermined upper limit value and lower limit value. Subsequently, the calculated correction value is multiplied by a corresponding coefficient depending on whether the measured value is a positive value or a negative value. Further, the multiplied correction value is inverted in sign to become a voltage frequency correction value Δfdv for the direct current. That is, when the measured value is a voltage related to a direct current, the frequency correction value Δfdv for voltage related to the direct current is calculated as the frequency correction value Δf by the calculation method shown in the figure.

  Specifically, when the voltage related to the direct current converted from the alternating current transmitted to the storage battery system becomes a value equal to or higher than the first upper limit value, the self-sustained operation control device uses the voltage for the direct current related to a positive value. The frequency correction value Δfdv is sent to the storage battery system as the frequency correction value Δf. Thereby, the storage battery system can change the internal frequency f (refer FIG. 4) with the frequency correction value (DELTA) f. Therefore, the self-sustained operation control device can reduce the electric power related to the alternating current transmitted to the storage battery system by causing the storage battery system to change the internal frequency f. For this reason, the self-sustained operation control device can reduce the current related to the direct current by reducing the power related to the alternating current transmitted to the storage battery system. Therefore, the self-sustained operation control device can lower the voltage related to the direct current by lowering the current related to the direct current flowing into the storage battery.

  FIG. 15 is a control block diagram illustrating an example of a method of calculating a frequency correction value when the measured value according to an embodiment of the present invention is a temperature related to a storage battery. In addition, FIG. 15 shows an example of a calculation method on the upper limit side among the calculation methods of the frequency correction value when the measured value is the temperature related to the storage battery. That is, FIG. 15 is an example of a calculation method used when the measured value is a positive value.

  For example, as shown in the figure, the autonomous operation control device compares the measured value with the first upper limit value and calculates the difference value. Next, the self-sustained operation control device calculates a correction value corresponding to the difference value using a frequency adjuster or the like. The calculated correction value is adjusted by an upper / lower limiter or the like so as to be a value within a predetermined upper limit value and lower limit value. Subsequently, the calculated correction value is multiplied by a corresponding coefficient depending on whether the measured value is a positive value or a negative value. Further, the multiplied correction value is inverted in sign to become a temperature frequency correction value Δft. That is, when the measured value is a temperature related to the storage battery, the frequency correction value Δft for the temperature is calculated as the frequency correction value Δf by the calculation method shown in the figure.

  Specifically, when the temperature related to the storage battery becomes a value equal to or higher than the first upper limit value, the self-sustained operation control device sends the temperature correction value Δft for the positive value as the frequency correction value Δf to the storage battery system. Thereby, the storage battery system can change the internal frequency f (refer FIG. 4) with the frequency correction value (DELTA) f. Therefore, the self-sustained operation control device can reduce the electric power related to the alternating current transmitted to the storage battery system by causing the storage battery system to change the internal frequency f. For this reason, the self-sustained operation control device can reduce the current related to the direct current by reducing the power related to the alternating current transmitted to the storage battery system. Therefore, the self-sustained operation control device can lower the temperature related to the storage battery by reducing the current related to the direct current flowing into the storage battery.

  FIG. 16 is a control block diagram illustrating an example of a method of calculating a frequency correction value when the measured value according to the embodiment of the present invention is a charging rate related to a storage battery. In addition, FIG. 16 shows an example of a calculation method on the upper limit side among the calculation methods of the frequency correction value when the measured value is the charging rate related to the storage battery. That is, FIG. 16 is an example of a calculation method used when the measured value is a positive value.

  For example, as shown in the figure, the autonomous operation control device compares the measured value with the first upper limit value and calculates the difference value. Next, the self-sustained operation control device calculates a correction value corresponding to the difference value using a frequency adjuster or the like. The calculated correction value is adjusted by an upper / lower limiter or the like so as to be a value within a predetermined upper limit value and lower limit value. Subsequently, the calculated correction value is multiplied by a corresponding coefficient depending on whether the measured value is a positive value or a negative value. Further, the multiplied correction value is inverted in sign to become a charging rate frequency correction value Δfs. That is, when the measured value is the charging rate related to the storage battery, the charging rate frequency correction value Δfs is calculated as the frequency correction value Δf by the calculation method shown in the figure.

  Specifically, when the charging rate related to the storage battery becomes a value equal to or higher than the first upper limit value, the self-sustained operation control device sends the charging rate frequency correction value Δfs, which is a positive value, to the storage battery system as the frequency correction value Δf. . Thereby, the storage battery system can change the internal frequency f (refer FIG. 4) with the frequency correction value (DELTA) f. Therefore, the self-sustained operation control device can reduce the electric power related to the alternating current transmitted to the storage battery system by causing the storage battery system to change the internal frequency f. For this reason, the self-sustained operation control device can reduce the current related to the direct current by reducing the power related to the alternating current transmitted to the storage battery system. Therefore, the self-sustained operation control device can lower the charging rate related to the storage battery by lowering the current related to the direct current flowing into the storage battery.

  The frequency correction value Δf may be calculated by combining the calculated frequency correction values by the calculation methods shown in FIGS.

  FIG. 17 is a control block diagram illustrating an example of a method for calculating a frequency correction value by a combination of frequency correction values according to an embodiment of the present invention. Specifically, FIG. 17 shows that the self-sustained operation control apparatus has a power frequency correction value Δfv, a current frequency correction value Δfc related to DC current, a voltage frequency correction value Δfdv related to DC current, and a frequency correction value Δft for temperature. And a charging rate frequency correction value Δfs is a diagram illustrating an example of a method for calculating the frequency correction value Δf.

  The power frequency correction value Δfv is a frequency correction value calculated by, for example, the calculation method shown in FIG. Further, the current frequency correction value Δfc related to the direct current is a frequency correction value calculated by a calculation method shown in FIG. 13, for example. Further, the voltage frequency correction value Δfdv related to the direct current is a frequency correction value calculated by a calculation method shown in FIG. 14, for example. Furthermore, the temperature frequency correction value Δft is a frequency correction value calculated by a calculation method shown in FIG. 15, for example. Furthermore, the charge rate frequency correction value Δfs is a frequency correction value calculated by a calculation method shown in FIG. 16, for example.

  Specifically, in the calculation method shown in FIG. 17, the autonomous operation control device selects the frequency correction value having the largest value among the frequency correction values as the maximum frequency correction value Δfmax. Next, the autonomous operation control apparatus sends the maximum frequency correction value Δfmax to the storage battery system as the frequency correction value Δf (see FIG. 11A). Thereby, the storage battery system can change the internal frequency f (refer FIG. 4) with the frequency correction value (DELTA) f.

  In FIG. 17, the frequency correction value having the largest value among the frequency correction values is selected as the maximum frequency correction value Δfmax. The frequency correction value having the largest value corresponds to the measurement value having the largest difference from the first upper limit value or the first lower limit value. Therefore, when the frequency correction value having the largest value is defined as the frequency correction value Δf, the autonomous operation control device sets the internal frequency f to the storage battery system corresponding to the measured value having the largest difference from the first upper limit value or the first lower limit value. Can be changed. Therefore, the autonomous operation control device further stabilizes the autonomous operation control system by changing the internal frequency f to the storage battery system corresponding to the measured value having the largest difference from the first upper limit value or the first lower limit value. Can do. Therefore, the autonomous operation control device can increase the operation rate of the autonomous operation control system 1 by further stabilizing the autonomous operation control system.

  In addition, it is preferable that a measured value is a value which shows the electric power or electric current which concerns on an alternating current. When the measured value indicates the power or current related to the alternating current, the independent operation control device can adjust the power or current related to the alternating current by changing the internal frequency f (see FIG. 4) based on the measured value. Therefore, the self-sustaining operation control device can reduce the case where the measured value is the power or current related to the alternating current when the measured value is the power or current related to the alternating current. Therefore, the self-sustained operation control device can reduce and protect the breakage of the inverter or the like included in the storage battery system due to the electric power or current related to the large alternating current. Therefore, when the storage battery system is protected, the operation rate of the storage battery system increases, so that the autonomous operation control system can increase the operation rate of the autonomous operation control system.

  Moreover, it is preferable that the value which shows the voltage which concerns on a direct current is contained in a measured value. The voltage related to the direct current can be measured with a simple sensor or the like. Therefore, when the value indicating the voltage related to the direct current is included in the measured value, the self-sustained operation control system can simplify the device for generating the measured value.

  Further, the measured value preferably includes a value indicating the temperature related to the storage battery. The temperature related to the storage battery can be measured with a simple sensor or the like. Therefore, when the value indicating the temperature related to the storage battery is included in the measured value, the self-sustained operation control system can simplify the device for generating the measured value.

  More preferably, the measured value preferably includes a voltage indicating a direct current and a value indicating a charging rate related to the storage battery. When the voltage related to the direct current increases, the internal device or the like of the storage battery may be damaged. In addition, when the charging rate of the storage battery increases, the voltage related to the direct current often increases. Therefore, when the charging rate increases and the voltage related to the direct current increases, internal devices and the like of the storage battery may be damaged.

  Therefore, when the voltage related to the direct current and the charging rate related to the storage battery are included in the measured values, the autonomous operation control device can reduce the increase of the voltage related to the direct current. Therefore, the self-sustained operation control device can protect internal devices and the like of the storage battery from damage by including the voltage related to the direct current and the value indicating the charging rate related to the storage battery in the measured value. Therefore, when the storage battery is protected from breakage, the operation rate of the storage battery increases, so that the autonomous operation control system can increase the operation rate of the autonomous operation control system.

  Note that the measurement value may be a current related to a direct current, which often has the same tendency as the power or current related to the alternating current.

<< Example of obtaining maximum power (step S260) >>
Returning to FIG. 6, the autonomous operation control device acquires the maximum power A from the storage battery system (step S260). Specifically, for example, when the autonomous operation control system 1 shown in FIG. 8 and the counter value k = 1, in step S260, the autonomous operation control device receives the maximum power A from the storage battery system 11A (see FIG. 8). To get. In the independent operation control system 1 shown in FIG. 8, the maximum power A of the storage battery system 11A is “500”. Therefore, when the autonomous operation control system 1 shown in FIG. 8 and the counter value k = 1, in step S260, the autonomous operation control device acquires a value of “500” as the maximum power A from the storage battery system 11A.

  Moreover, when the process of step S260 is performed, it is a case where the electric power which concerns on the alternating current in a 1st range is transmitted to the storage battery system corresponding to the counter value k. Therefore, in step S260, the storage battery system corresponding to the counter value k charges the electric power related to the AC current to be transmitted.

<< Example of addition of output limit value P (step S270) >>
The independent operation control device adds the maximum power A to the output limit value P (step S270). For example, the independent operation control system 1 shown in FIG. 8 will be described as an example. Specifically, when the counter value k = 1, the output limit value P is “0” by the process of step S210. Furthermore, since the maximum power A of the storage battery system 11A (see FIG. 8) is “500”, the maximum power A is “500”. Therefore, when the counter value k = 1, the output limit value P is changed from “0 + 500” to “500” by the process of step S270.

  Next, when the counter value k = 2, the output limit value P becomes “500” by the process of the counter value k = 1. Furthermore, since the maximum power A of the storage battery system 11B (see FIG. 8) is “500”, the maximum power A is “500”. Therefore, when the counter value k = 2, the output limit value P is changed from “500 + 500” to “1000” by the process of step S270.

  Further, when the counter value k = 3, the output limit value P becomes “1000” by the process of the counter value k = 2. Furthermore, since the maximum power A of the storage battery system 11C (see FIG. 8) is “500”, the maximum power A is “500”. Therefore, when the counter value k = 3, the output limit value P is changed from “1000 + 500” to “1500” by the process of step S270.

<< Count-up process example of counter value k (step S280) >>
The independent operation control device adds “1” to the counter value k (step S280). That is, in step S280, the autonomous operation control apparatus counts up a so-called counter value k.

<< Judgment example of whether or not the counter value k is larger than the number n of storage battery systems (step S290) >>
The autonomous operation control device determines whether or not the counter value k is larger than the number n of storage battery systems (step S290). Specifically, when the counter value k is larger than the number n of storage battery systems (YES in step S290), the autonomous operation control device proceeds to step S2A0. On the other hand, if the counter value k is not greater than the number n of storage battery systems (NO in step S290), the autonomous operation control apparatus proceeds to step S220. That is, in step S290, the autonomous operation control device determines whether or not the processes of steps S220 to S280 have been performed for each of the n storage battery systems included in the autonomous operation control system. That is, when all the processes of steps S220 to S280 have been completed for each of the n storage battery systems included in the autonomous operation control system (YES in step S290), the autonomous operation control device proceeds to step S2A0.

<< Calculation Example of Output Limit Value P (Step S2A0) >>
The independent operation control device calculates an output limit value P (step S2A0). For example, the independent operation control system 1 shown in FIG. 8 will be described as an example. Specifically, the output limit value P is “1500” by the process of step S270. Furthermore, the power related to the alternating current consumed by the load facility 12 (see FIG. 1) included in the autonomous operation control system 1 is 150 kW. Here, in step S2A0, the self-sustained operation control apparatus adds the power related to the alternating current consumed by the load facility 12 to the output limit value P obtained by the process of step S270. That is, in the independent operation control system 1 shown in FIG. 8, in step S2A0, the independent operation control device calculates the output limit value P as “1650” from “1500 + 150 = 1650”.

<< Transmission Example of Output Limit Value P (Step S300) >>
Returning to FIG. 5, the self-sustained operation control apparatus sends the output limit value P to the power generation facility (step S300). Specifically, in the autonomous operation control system 1 shown in FIG. 8, the autonomous operation control device sends the value “1650” calculated by the calculation shown in FIG.

  Next, when the output limit value P is sent to the power generation facility, the power generation facility generates power related to the alternating current that is equal to or less than the output limit value P and transmits the generated power. That is, the self-sustained operation control device can control the power related to the alternating current generated and transmitted by the power generation facility by the output limit value P. Note that the processing in step S300 is performed at regular time intervals based on the specifications of the power generation equipment and the like.

≪Judgment example of whether to end autonomous operation (step S400) ≫
The independent operation control device determines whether or not to end the independent operation (step S400). Specifically, when the autonomous operation control device determines that the autonomous operation is to be terminated (YES in step S400), the autonomous operation control device terminates the entire process by the autonomous operation control system. On the other hand, when the independent operation control device determines not to end the independent operation (NO in step S400), the independent operation control device proceeds to step S200.

  For example, when an operation for terminating the independent operation is performed by a system administrator or the like, the autonomous operation control device terminates the entire process by the autonomous operation control system (YES in step S400). For example, when the entire process by the autonomous operation control system is terminated, the autonomous operation control device disengages the power generation facility, disengages the load facility, and stops each storage battery system.

  On the other hand, if the system administrator or the like does not perform an operation for terminating the independent operation, the independent operation control device repeats Step S200 and Step S300 and continues the independent operation (NO in Step S400).

<< 5. Functional configuration example ≫
FIG. 18 is a functional block diagram showing an example of the functional configuration of the autonomous operation control apparatus in one embodiment of the present invention. Specifically, the autonomous operation control device 10 includes an acquisition unit 200 and a control unit 201.

  The acquisition unit 200 acquires measurement values from the storage battery system 11 using the measurement data 2. In addition, like the self-sustaining operation control system 1 illustrated in FIG. 8, when the self-sustaining operation control system 1 includes a plurality of storage battery systems 11, the acquisition unit 200 acquires measurement values from each storage battery system 11. As illustrated in FIG. 7, when a plurality of types of measurement values are used, the acquisition unit 200 acquires measurement values corresponding to the respective types from the storage battery system 11. The acquisition unit 200 is realized by, for example, the network I / F 103 (see FIG. 2).

  The control unit 201 controls the storage battery system 11 and the power generation facility 13 based on the measurement value. Specifically, when the measured value is a value equal to or greater than the first upper limit value or the measured value is equal to or less than the first lower limit value, the control unit 201 performs alternating current through the process of step S251 (see FIG. 6). The frequency related to the current is changed by the storage battery system. Further, when the measured value is a value equal to or greater than the second upper limit value or the measured value is equal to or less than the second lower limit value, the control unit 201 transmits power to the power generation facility by the process of step S241 (see FIG. 6). To restrict. Further, when the measured value is a value equal to or greater than the third upper limit value or the measured value is equal to or smaller than the third lower limit value, the control unit 201 operates the storage battery system by performing the process of step S231 (see FIG. 6). To restrict. Note that the control unit 201 is realized by, for example, the CPU 101 (see FIG. 2), the network I / F 103, and the like.

  Moreover, the data of table TB shown in FIG. 7 etc. are input into the independent operation control apparatus 10 by the system administrator etc. Therefore, the control unit 201 is acquired by the acquisition unit 200 with the first upper limit value, the first lower limit value, the second upper limit value, the second lower limit value, the third upper limit value, and the third lower limit value indicated by the table TB. The measured value can be compared.

  Furthermore, the autonomous operation control device 10 acquires a measurement value by the acquisition unit 200. Next, the autonomous operation control apparatus 10 determines whether the measurement value is a value equal to or higher than the first upper limit value or a value equal to or lower than the first lower limit value based on the table TB by the control unit 201. Subsequently, when the measured value is equal to or greater than the first upper limit value or the measured value is equal to or less than the first lower limit value, the autonomous operation control device 10 uses the control unit 201 to set the frequency related to the alternating current to the storage battery system. 11 is changed. Thereby, the storage battery system 11 can change the frequency which concerns on alternating currents, such as internal frequency f (refer FIG. 4).

  The autonomous operation control device 10 can lower the electric power related to the alternating current transmitted to the storage battery system 11 by causing the storage battery system 11 to change the frequency related to the alternating current. Furthermore, by lowering the electric power related to the alternating current transmitted to the storage battery system 11, the autonomous operation control device 10 relates to the alternating current transmitted to each of the plurality of storage battery systems 11, as shown in FIG. The power can be made uniform and a value within the first range. Therefore, the self-sustained operation control device 10 can lengthen the time for transmitting the power related to the constant alternating current consumed by the load facility 12 to the load facility 12. Therefore, the autonomous operation control device 10 can increase the operating rate of the autonomous operation control system 1 by changing the internal frequency f to the storage battery system 11.

  Furthermore, the autonomous operation control apparatus 10 determines whether the measured value is a value equal to or greater than the second upper limit value or a value equal to or less than the second lower limit value based on the table TB by the control unit 201. Subsequently, when the measured value is equal to or larger than the second upper limit value or the measured value is equal to or smaller than the second lower limit value, the autonomous operation control device 10 causes the power generation facility to limit power transmission. Next, when power transmission from the power generation facility 13 is restricted, the storage battery system 11 discharges an alternating current. Subsequently, the alternating current discharged from each storage battery system is transmitted to the load facility 12. Therefore, even if power transmission from the power generation facility 13 is restricted to the load facility 12, electric power related to a certain alternating current consumed by the load facility 12 is transmitted to the load facility 12. Therefore, the self-sustained operation control system 1 can lengthen the time for transmitting the power related to the constant alternating current consumed by the load facility 12 to the load facility 12. Therefore, the autonomous operation control device 10 can increase the operation rate of the autonomous operation control system 1 by restricting the power generation facility 13 to transmit power.

≪ 6. Comparative example ≫
FIG. 19 is an overall configuration diagram illustrating an example of an overall configuration of a self-sustained operation control system of a comparative example. Specifically, in FIG. 19, a self-sustained operation control system 1 </ b> A having each storage battery system, load facility 12, and power generation facility 13 similar to the autonomous operation control system 1 illustrated in FIG. 8 is illustrated as a comparative example.

  First, as in FIG. 11 (A) and the like, it is assumed that the overshoot phenomenon and the like, and the power related to each AC current transmitted to each storage battery system varies. Furthermore, in the independent operation control system 1A, for example, as shown in FIG. 19A, it is assumed that the electric power related to the alternating current is transmitted to each storage battery system.

  Next, when it becomes like FIG. 19 (A), the electric power of 520 kW which cannot be charged is transmitted to the storage battery system 11C. Therefore, the storage battery system 11C stops operation and does not perform charging. Subsequently, when the storage battery system 11C stops operation, the power related to the alternating current transmitted to the storage battery system 11C is distributed and transmitted to the storage battery system 11A and the storage battery system 11B. 19 (B).

  Subsequently, in FIG. 19B, electric power related to an alternating current of 750 kW is transmitted to the storage battery system 11A and the storage battery system 11B. In this case, the storage battery system 11A and the storage battery system 11B are each supplied with electric power related to an AC current of 750 kW that cannot be charged. Therefore, the storage battery system 11A and the storage battery system 11B stop operation, and the respective storage batteries Prevent the system from charging.

  Subsequently, when the storage battery system 11A, the storage battery system 11B, and the storage battery system 11C stop operation, the autonomous operation control system 1A enters the state shown in FIG. That is, since the power related to the alternating current is not transmitted to each storage battery system, the power related to the 1650 kW alternating current transmitted by the power generation facility 13 is transmitted to the load facility 12. In this case, 1650 kW of electric power, which is larger than the power related to the consumed alternating current, is transmitted to the load facility 12, so that the load facility 12 is cut off as shown in FIG. Disconnect using a container. Therefore, the operation of the autonomous operation control system 1A as a whole is stopped by the disconnection of the load facility 12.

  That is, if the overshoot phenomenon and the power related to the alternating current transmitted to the storage battery system vary, the storage battery systems may stop in a chained manner, and the operation of the entire autonomous operation control system 1A may stop. In addition, as shown in FIG. 19C, when the power related to the AC current of 1650 kW larger than the power related to the AC current consumed by the load facility 12 is transmitted to the load facility 12, the load facility 12 may be damaged. is there.

  FIG. 20 is an overall configuration diagram illustrating an example of an overall configuration of a self-sustained operation control system of another comparative example. Specifically, in FIG. 20, a self-sustained operation control system 1A similar to that in FIG. 19 is used as a comparative example.

  First, even if there is a variation in the electric power related to the alternating current transmitted to each storage battery system, the electric power related to the alternating current transmitted to each storage battery system, as shown in FIG. In some cases, the electric power is related to an alternating current that can be charged. However, as shown in FIG. 20A, for example, a storage battery, due to factors other than power related to AC current such as a voltage related to DC current, a current related to DC current, a charging rate related to storage battery, or a temperature related to storage battery The system 11C may stop operation and prevent charging. If it becomes like this, since the electric power based on the alternating current transmitted to 11 C of storage battery systems is distributed and transmitted to 11 A of storage battery systems and the storage battery system 11B similarly to FIG.19 (B), 1A of independent operation control systems are The state shown in FIG.

  Therefore, in FIG. 20B, the electric power related to the AC current of 670 kW is transmitted to the storage battery system 11A, and further, the electric power related to the AC current of 680 kW is transmitted to the storage battery system 11B. If it becomes like this, since the electric power which concerns on the alternating current which cannot charge both will be transmitted to 11 A of storage battery systems and the storage battery system 11B, 11 A of storage battery systems and the storage battery system 11 B will each stop driving | operation, and each storage battery system Avoid charging.

  Subsequently, when the storage battery system 11A, the storage battery system 11B, and the storage battery system 11C stop operation, the autonomous operation control system 1A enters the state shown in FIG. Since the power related to the alternating current is not transmitted to each storage battery system, the power related to the 1500 kW alternating current transmitted by the power generation facility 13 is transmitted to the load facility 12. If it becomes like this, since the electric power which concerns on the 1500 kW alternating current larger than the electric power which concerns on the alternating current consumed is transmitted to the load equipment 12, load equipment 12 is for equipment protection, for example of FIG. Thus, the circuit is disconnected by a circuit breaker or the like. Therefore, the operation of the autonomous operation control system 1A as a whole is stopped by the disconnection of the load facility 12. That is, due to factors other than the electric power related to the alternating current, the storage battery systems may be stopped in a chain manner, and the operation of the entire autonomous operation control system 1A may be stopped. In addition, as illustrated in FIG. 20C, when the power related to the 1500 kW AC current larger than the power related to the AC current consumed by the load facility 12 is transmitted to the load facility 12, the load facility 12 may be damaged. is there.
