When increasing the power generated by the photovoltaic power generation facility and decreasing the power generated by the wind power generation facility, the control unit increases the power generated by the photovoltaic power generation facility during at least a part of the period during which the power generation by the photovoltaic power generation facility is increased. The power generated by the solar power generation facility may be controlled such that the rate of increase in the power generated by the facility is less than or equal to the rate of decrease in the power generated by the wind power generation facility.

The power generated by the solar power generation facility is controlled so that the rate of increase in the power generated by the solar power generation facility decreases when the sum of the value and the second output upper limit becomes equal to or greater than the upper limit of the allowable power generation amount. you can

The control unit temporarily decreases the control target value of the solar power generation equipment by the first correction amount when reducing the power generated by the solar power generation equipment and reducing the power generated by the wind power generation equipment. good.

The second correction amount may be smaller than the difference between the current power generation and the target power generation of the wind turbine generator.

The difference between the current generated power and the target generated power of the wind power generation facility when each generated power is decreased and the difference between the first correction amount is the difference between the current generated power of the wind power generation facility and the target when each generated power is increased. It may be larger than the difference between the generated power and the second correction amount.

Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Also, not all combinations of features described in the embodiments are essential for the solution of the invention.

FIG. 1 shows an outline of a power generation system 2 in which a power generation control device 100 of the present invention is used. The power generation system 2 includes a photovoltaic power generation facility 10 , a wind power generation facility 20 , and an interconnection point 30 . The photovoltaic power plant 10 may include multiple photovoltaic power plants 10-1 and 10-2. The wind power plant 20 may include multiple wind power plants 20-1, 20-2, and 20-3. However, the number of photovoltaic power generation facilities 10 and wind power generation facilities 20 is not limited. Each of the photovoltaic power generation equipment 10 and the wind power generation equipment 20 may be one.

The photovoltaic power generation facility 10 and the wind power generation facility 20 are electrically connected to the same interconnection point 30 via power transmission lines. Electric power generated by the solar power generation facility 10 and the wind power generation facility 20 may be supplied to the substation 4 via the interconnection point 30 . The substation 4 may be connected to a commercial power grid 6 .

When the power generator connects the generator to the commercial power system 6, the maximum output power (sometimes referred to as interconnection capacity) supplied by the generator is determined in advance. The interconnection capacity may be determined based on the rated output of the generator. When a plurality of types of generators are connected to one interconnection point 30, the total value of generated power (combined output value) of all generators is controlled to be equal to or less than the upper limit of the allowable power generation amount. In this example, the power generation control device 100 controls each power generator so that the total value of power generated by a plurality of types of power generation equipment does not exceed the upper limit of the allowable amount set below the coupling capacity.

FIG. 2 shows an example of a power generation system 2 having the power generation control device 100 of the first embodiment. The power generation system 2 includes a power conditioner 12 for photovoltaic power generation. The power conditioner 12 is called a PCS (Power Conditioning Subsystem). The power conditioner 12 may include an inverter device 14 and an output control section 16 . The inverter device 14 is connected to the photovoltaic power generation facility 10 . The inverter device 14 converts the DC power generated by the photovoltaic power generation facility 10 into AC power. The output control unit 16 receives control signals from the power generation control device 100 . The output control unit 16 controls the power generated by the photovoltaic power generation facility 10 according to the received control signal. Specifically, the output control unit 16 controls AC power output via the inverter device 14 .

The power generation system 2 includes a wind power generation controller 22 . The wind power generation control unit 22 controls power generated by the wind power generation equipment 20 . Specifically, the wind power generation equipment 20 generates power using wind turbine blades as a mechanical driving unit. In one example, the wind power generation control unit 22 controls the power generated by the wind power generation equipment 20 by pitch control that adjusts the angle of the blades of the wind turbine.

Power conditioner 12 and interconnection point 30 may be electrically connected by transmission line 18 . A transformer 36 may be provided between the power conditioner 12 and the interconnection point 30 . A transformer 37 may be provided between the interconnection point 30 and the substation 4 . The wind power generation facility 20 and the interconnection point 30 may be electrically connected by a transmission line 24 .

The power generation system 2 includes power meters 32 and 34 for measuring the power generated by each power generation facility. The wattmeter 32 is connected to the power line between the photovoltaic power generation facility 10 and the interconnection point 30 to measure the power generated by the photovoltaic power generation facility 10 . The wattmeter 34 is connected to the power line between the wind power generation equipment 20 and the interconnection point 30 to measure the power generated by the wind power generation equipment 20 . The generated power values measured by the power meters 32 and 34 are supplied to the generated power monitoring unit 120 of the power generation control device 100 .

The power generation control device 100 controls power generated by the power generation system 2 including the solar power generation equipment 10 and the wind power generation equipment 20 . The power generation control device 100 includes a control section 110 . The power generation control device 100 may further include a power generation monitoring unit 120 and a storage unit 130 . The power generation control device 100 may be configured by a computer such as a PLC (Programmable Logic Controller). Each unit such as the control unit 110 and the generated power monitoring unit 120 may be implemented as a function of a CPU that executes a control program.

The control unit 110 may control the solar power generation equipment 10 and the wind power generation equipment 20 to limit the total value of the generated power at the interconnection point 30 to be equal to or less than the upper limit of the allowable power generation amount. When controlling the power generated by the wind power generation equipment 20 , the control unit 110 controls the power generated by the photovoltaic power generation equipment 10 based on the delay characteristics of the wind power generation equipment 20 . In this specification, the delay characteristic means the delay of fluctuation in the actual generated power after issuing a command to control the generated power.

The generated power monitoring unit 120 monitors the current generated power of the wind turbine generator 20 . The generated power monitoring unit 120 of this example also monitors the current generated power of the photovoltaic power generation facility 10 . In one example, the generated power monitoring unit 120 may acquire the current power generated by the photovoltaic power generation facility 10 from the power meter 32 . The generated power monitoring unit 120 may acquire the current power generated by the wind turbine generator 20 from the power meter 34 . The power meters 32 and 34 may function as generated power monitoring units.

The storage unit 130 may store each piece of information that the control unit 110 uses for control. In one example, the storage unit 130 may store information about delay characteristics of the wind turbine generator 20 . In addition, the storage unit 130 may store weather information such as the upper limit of the allowable amount of power generation at the interconnection point 30 and the wind speed and direction acquired from the outside. The storage unit 130 may store destination information when transmitting control signals to the output limiting mechanisms of the solar power generation equipment 10 and the wind power generation equipment 20 via the network.

FIG. 3 shows an example of output limitation in a comparative example. FIG. 3 shows the ratio (%) of the power generated by each power generation facility to the interconnection capacity when the power generated by the photovoltaic power generation facility 10 rises sharply. In the comparative example in FIG. 3, the control unit 110 controls the power generation of the wind power generation equipment 20 as the power generated by the photovoltaic power generation equipment 10 (PV output) increases from 50% to 100% of the interconnection capacity. It shows the case where the power (WT output) is reduced from 20% to 0% of the interconnection capacity.

In the wind power generation equipment 20, for example, the power generated by the wind power generation equipment 20 is controlled by pitch control that adjusts the angle of the blades of the wind turbine. That is, mechanical action is required to change the generated power. Therefore, the delay time A from receiving a command to control the generated power to when the generated power actually fluctuates is longer than the delay time in the photovoltaic power generation equipment 10 . For example, it takes 1 second to change the power generated by the wind turbine generator 20 by 5%.

Therefore, when the power generated by the solar power generation equipment 10 is rapidly changed while the power generated by the wind power generation equipment 20 is reduced, the power generated by the wind power generation equipment 20 cannot be suppressed in time, and the power generation at the interconnection point 30 There is a risk that the combined output, which is the total value of power, will exceed the upper limit value X1 of the predetermined allowable power generation amount. The upper limit of the predetermined allowable amount may be the interconnection capacity, and may be a value defined in the range of 90% or more and 99% or less of the interconnection capacity.

4 and 5 are examples of output limitation in the power generation control device 100 of the first embodiment. 4 and 5, the horizontal axis indicates the time, and the vertical axis indicates the ratio (%) of the power generated by each power generation facility to the interconnection capacity. In the example shown in FIGS. 4 and 5, the control unit 110 adds a first margin to the current power generation (PV output) of the photovoltaic power generation facility 10 to obtain a first output upper limit value (first output limit value). value). The control unit 110 adds a second margin to the current generated power (WT output) of the wind power generation equipment 20 to set a second output upper limit value (second output limit value). The first margin may be 8% or less of the rated power of the photovoltaic power generation facility 10, more preferably 4% or more and 6% or less, or 5%. The second margin may be 8% or less of the rated power of the wind power generation facility 20, more preferably 4% or more and 6% or less, or 5%.

As shown in FIG. 4, when the sum of the first output upper limit value and the second output upper limit value is less than the upper limit value of the allowable power generation amount, the solar power generation equipment 10 and the wind power generation equipment 20 output You can generate power without being restricted.

FIG. 5 shows the details of control when the sum of the first output upper limit value and the second output upper limit value is greater than or equal to the upper limit value of the allowable power generation amount. When the sum of the first output upper limit value and the second output upper limit value is greater than or equal to the upper limit value of the allowable power generation amount, the control unit 110, as indicated by B in FIG. The power generated by the photovoltaic power generation facility is controlled so that the rate of increase in the power generated by the solar power generation facility is less than or equal to the rate of decrease in the power generated by the wind power generation facility (A in FIG. 5). As used herein, the rate of increase means the amount of increase per unit time, and the rate of decrease means the amount of decrease per unit time.

Specifically, the control unit 110 may limit the increase rate of the output upper limit value (output limit value) of the photovoltaic power generation equipment 10 based on the delay characteristics when the power generated by the wind power generation equipment 20 is reduced. . If the delay characteristic of the wind power generation equipment 20 is 5%/second, the control unit 110 controls the solar power generation equipment 10 so that the increase rate of the output upper limit value (output limit value) of the photovoltaic power generation equipment 10 is 5%/second or less. Controls the power generated by photovoltaic power generation equipment. Information about such an increase rate may be stored in the storage unit 130 in advance.

The control unit 110 controls the increase rate of the power generated by the photovoltaic power generation facility 10 when the sum of the first output upper limit value and the second output upper limit value is smaller than the upper limit value of the allowable power generation amount (C in FIG. 5) , the increase rate of the power generated by the photovoltaic power generation equipment 10 when the sum of the first output upper limit value and the second output upper limit value is equal to or higher than the upper limit value of the allowable power generation amount (B in FIG. 5 ), the power generated by the photovoltaic power generation equipment may be controlled.

Therefore, even when the power generated by the photovoltaic power generation facility 10 increases, the control unit 110 does not limit the rate of increase from the initial point of the increase in the generated power, but sets the first output upper limit and the second The increase rate may be suppressed when the sum of the output upper limit value and the upper limit value of the allowable power generation amount is exceeded as a trigger. That is, the increase rate of the power generated by the photovoltaic power generation facility 10 is suppressed during at least a part of the period during which the power generated by the photovoltaic power generation facility 10 is increased. Therefore, it is possible to prevent an increase in the suppression amount of the power generated by the photovoltaic power generation, compared to the case where the rate of increase is suppressed from the initial point of increase in the power generated. On the other hand, it is possible to prevent the total value of electric power at the interconnection point 30 from exceeding the upper limit of the allowable power generation amount.

In particular, in this example, each output upper limit value is varied so as to follow the power generated by the solar power generation equipment 10 and the power generated by the wind power generation equipment 20 . In this way, by setting the output upper limit value of each power generation facility to a value close to the value of the current power generation without fixing it, when the power generation suddenly changes, the combined output at the interconnection point 30 will be the upper limit of the allowable power generation amount. to prevent it from exceeding

FIG. 6 shows an example of a control block of the power generation control device 100. As shown in FIG. The control unit 110 of this example includes a first output upper limit calculation unit 111, a second output upper limit calculation unit 112, a total value calculation unit 113, a comparison unit 114, an increase rate limiting unit 115, a first switching unit 116, a second A switching unit 117 and a second output upper limit updating unit 118 may be included.

FIG. 7 is a flowchart showing an example of processing of the power generation control device 100 of the first embodiment. FIG. 7 shows an example of a power generation control method for controlling the power generated by the power generation system 2 including the photovoltaic power generation equipment 10 and the wind power generation equipment 20 . The power generation control method controls the power generated by the solar power generation equipment 10 based on the delay characteristics of the wind power generation equipment 20 when controlling the power generated by the wind power generation equipment 20 .

The power meter 32 measures the currently generated power (PV output) P _POUT of the photovoltaic power generation equipment 10, and the power meter 34 measures the current generated power (WT output) P _WOUT of the wind power generation equipment 20 (step S101). . When there are a plurality of photovoltaic power generation facilities 10, the generated power monitoring unit 120 may calculate the total power generated by the plurality of photovoltaic power generation facilities 10 as the current power generation _PPOUT . The same applies to the current power generation P _WOUT .

The first output upper limit value calculation unit 111 adds a first margin P _PMG to the current power generation (PV output) P _POUT of the photovoltaic power generation equipment 10 to obtain a first output upper limit value (first output limit value) _PPMX is calculated (step S102). Similarly, the second output upper limit calculation unit 112 adds the second margin P _WMG to the current generated power (WT output) P _WOUT of the wind power generation equipment 20 to obtain the second output upper limit (second output limit). value) P _WMX is calculated (step S102). The combined value calculator 113 calculates the sum P _SMX of the first output upper limit value P _PMX and the second output upper limit value P _WMX (step S103).

The comparison unit 114 compares the sum P _SMX of the first output upper limit value P _PMX and the second output upper limit value P _WMX with the upper limit value X1 (for example, interconnection capacity) of the allowable power generation amount (step S104). If the sum P _SMX is less than the upper limit X1 of the allowable power generation amount (step S104: NO), the comparison unit 114 may output a logical value of zero. In this case, the first switching unit 116 and the second switching unit 117 transmit the current first output upper limit P _PMX and second output upper limit P _WMX calculated in step S102 to each power generation equipment (step S106 ). If the sum P _SMX is equal to or greater than the upper limit X1 of the allowable power generation amount (step S104: YES), the comparison unit 114 may output a logical value of 1. In this case, the increase rate limiting unit 115 sets the increase rate of PPMX to a value determined based on the delay characteristics of the wind power generation equipment so that the increase rate of the photovoltaic power generation is equal to or less than the decrease rate of the wind power generation power. is restricted (step S105).

Further, the second output upper limit value update unit 118 calculates a new second output upper limit value P _WMX by subtracting the change amount P _PMXV of the photovoltaic power generation output P _PMX from the previous second output upper limit value P _WMXOLD . (step S105). Then, the control unit transmits the first output upper limit value P _PMX and the second output upper limit value P _WMX calculated in step S106 to each power generation equipment (step S106).

According to this example, the delay can be offset by the solar power generation until the fluctuation of the generated power of the wind power ends. Therefore, it is possible to prevent the total value of power at the interconnection point 30 from exceeding the upper limit of the allowable power generation amount.

In the power generation control device 100 of the first embodiment described above, the case where the margin is added to the current generated power to calculate the first output upper limit value and the second output upper limit value has been described. Also, a case has been described in which control unit 110 limits the rate of increase to an arbitrary value stored in storage unit 130 or the like. However, the power generation control device 100 is not limited to this case. When controlling the power generated by the wind power generation equipment 20 , the power generation control device 100 may control the power generated by the solar power generation equipment 10 based on the delay characteristics of the wind power generation equipment 20 .

FIG. 8 is an example of control in the power generation control device 100 of the second embodiment. The configuration of the power generation control device 100 of the second embodiment is the same as in FIG. The power generation control device 100 of the second embodiment includes a power generation monitor 120 that monitors the current power generated by the wind turbine generator 20 . The control unit 110 controls the power generated by the solar power generation equipment 10 based on the difference between the target power generation, which is the control target value of the power generated by the wind power generation equipment 20, and the current power generation. In an ideal state where the wind power generation equipment 20 has no delay characteristics, there is no difference between the current power generation of the wind power generation equipment 20 and the target power generation of the wind power generation equipment 20 . However, in reality, as described above, the wind turbine generator 20 has delay characteristics. A difference due to delay characteristics occurs between the current power generation of the wind power generation equipment 20 and the target power generation of the wind power generation equipment 20 . In other words, the difference represents the delay characteristics. The control unit 110 can measure measured values of delay characteristics at any time to control each generated power.

In this example, the difference between the current power generation and the target power generation in the wind power generation facility 20 is sequentially calculated at a predetermined sampling cycle, and the power generation of the photovoltaic power generation facility 10 is controlled according to the difference. Such control is a kind of feedback control based on the difference. For example, the greater the difference, the greater the influence of the delay characteristics of the wind power generation equipment 20 . Therefore, the controller 110 limits the power generated by the photovoltaic power generation facility 10 as the difference increases. As time passes and the difference becomes smaller, the limit on the power generated by the photovoltaic power generation facility 10 is relaxed.

Also in this example, the control unit 110 increases the power generated by the solar power generation equipment 10 and decreases the power generated by the wind power generation equipment 20 . The control unit 110 controls the rate of increase in the power generated by the solar power generation facility 10 (indicated by θ ₁ in the figure) to be equal to that of the wind power generation facility 20 during at least a part of the period in which the power generated by the solar power generation facility 10 is increased. The power generated by the photovoltaic power generation facility 10 is controlled so as to be equal to or less than the rate of decrease in the power generated ₍ indicated by θ2 in the figure).

FIG. 9 is a flowchart showing an example of processing in the power generation control device 100 of the second embodiment. The power meter 32 measures the power currently generated by the solar power generation facility 10, and the power meter 34 measures the power currently generated by the wind power generation facility 20 (step S201). The control unit 110 calculates the difference between the control target value for wind power generation and the current wind power generation power (output value) as a delay characteristic (step S202). Then, the photovoltaic power is limited based on the difference so that the increase rate of the photovoltaic power is equal to or less than the decrease rate of the wind power (step S203). In step S203, the control unit 110 may limit the first output upper limit value for photovoltaic power generation. The limited first output upper limit value (limit value) or the like is transmitted to each power generation facility as a control signal to control the power generated by each power generation facility (step S204).

Also in the second embodiment, the processing from step S101 to step S104 in the flowchart of FIG. 7 in the first embodiment may be executed. In this case, the margin is added to the current generated power to calculate the first output upper limit value and the second output upper limit value, and the sum of the first output upper limit value and the second output upper limit value is the allowable upper limit value X1. In the case above, the control unit 110 executes the processing from step S201 to step S204.

According to the power generation control device 100 of the second embodiment, the actually measured value of the delay characteristic can be measured at any time to control the generated power according to the delay characteristic of the wind turbine generator 20 . In addition, even if the storage unit 130 does not store information about delay characteristics in advance, it is possible to control the generated power.

FIG. 10 shows an example of a power generation system 2 having a power generation control device 100 of the third embodiment. The power generation control device 100 of this example includes a delay characteristic storage unit 132 . The delay characteristic storage unit 132 may store delay characteristics. The delay characteristic storage unit 132 may be a model, formula, graph, parameter, or the like for reproducing how the fluctuation of the generated power in the wind turbine generator 20 is delayed after issuing a command to control the generated power. A delay characteristic may act as an observer in the control. The control unit 110 can estimate the current delay effect based on the control target value of the wind power generation and the delay characteristics. Other configurations may be the same as those of the power generation control device 100 of the first embodiment.

FIG. 11 is an example of control in the power generation control device 100 of the third embodiment. FIG. 12 is a flowchart showing an example of processing in the power generation control device 100 of the third embodiment. The power meter 32 measures the power currently generated by the solar power generation facility 10, and the power meter 34 measures the power currently generated by the wind power generation facility 20 (step S301). The control unit 110 refers to the delay characteristics stored in the delay characteristics storage unit 132 (step S302). The delay characteristic may be obtained by experimentally calculating the delay characteristic of the wind turbine generator 20 in advance, or may be modeled theoretically. Delay characteristics may include non-linear characteristics of fluctuations in actual generated power after issuing a command to control generated power.

The control unit 110 refers to the delay characteristics in the delay characteristics storage unit 132 and estimates the current power generated by the wind power generation equipment 20 using the control target value for wind power generation (step S303). The generated power at each time t0, t1, t2, t3 is estimated. The control unit 110 controls the photovoltaic power according to the estimated value of the wind power so that the increase rate of the photovoltaic power is less than or equal to the decrease rate of the wind power (step S304). As shown in FIG. 11, even if the wind turbine generator 20 exhibits nonlinear delay characteristics, the control unit 110 can control the generated power based on the delay characteristics. The control unit 110 may transmit a control signal to each power generation facility to control the power generated by each power generation facility (step S305).

FIG. 13 shows an example of a power generation system 2 having the power generation control device 100 of the fourth embodiment.

The characteristic correction unit 142 may correct the delay characteristic based on at least one of the wind speed and wind direction at the place where the wind power generation equipment 20 is installed. In the wind power generation equipment 20, the power generated by the wind power generation equipment 20 is controlled by pitch control that adjusts the angle of the blades of the wind turbine. Therefore, the delay characteristics may change depending on the wind speed and wind direction.

Therefore, detailed description is omitted. Note that the power generation control device 100 of the fifth embodiment may further include the delay characteristic updating unit 140 described in the fourth embodiment.

In the first to fifth embodiments, mainly the processing in the case of increasing the power generated by the solar power generation equipment and decreasing the power generated by the wind power generation equipment 20 has been described. However, the power generation control device 100 is not limited to such processing.

FIG. 18 shows an example of control when both photovoltaic power generation output and wind power generation output are reduced. The left side of FIG. 18 shows output changes in the generated power (PV output) by the solar power generation equipment 10 and the output changes in the generated power (WT output) by the wind power generation equipment 20 in an ideal state. The right side of FIG. 18 shows the control contents in this example.

When reducing the power generated by the solar power generation equipment 10 and the power generated by the wind power generation equipment 20, the control unit 110 is larger than the difference L1 between the current power generation and the target power generation of the wind power generation equipment 20. The control target value of the photovoltaic power generation facility is temporarily decreased by the first correction amount L2.

For example, when receiving a request to reduce the interconnection capacity, it becomes necessary to decrease both the photovoltaic power generation and the wind power generation power to reduce the total value of the power generation at the interconnection point 30 . In such a case, it is desirable to reduce the total value of generated power to a predetermined value with as little delay as possible. Considering that it takes time to suppress the power generated by the wind power generation equipment 20, the control unit 110 temporarily decreases the control target value of the power generated by the photovoltaic power generation equipment 10. FIG.

FIG. 19 is a flow chart showing an example of processing in the power generation control device 100 when decreasing the photovoltaic power generation output and the wind power generation output. When the control unit 110 decreases the power generated by the solar power generation facility (step S501: YES) and also decreases the power generated by the wind power generation facility (step S502: YES), the processing from step S503 to step S505 is performed. can be executed.

The power meter 32 measures the power currently generated by the solar power generation facility 10, and the power meter 34 measures the power currently generated by the wind power generation facility 20 (step S503). The control unit 110 calculates the difference L1 between the control target value of wind power generation and the current wind power generation output value. Then, the control unit 110 temporarily decreases the control target value of the solar power generation equipment 10 by a first correction amount L2 that is larger than the difference L1 between the control target value for wind power generation and the current wind power generation power. As the power generated by the wind power generation equipment 20 decreases, the control unit 110 increases the control target value of the temporarily reduced power generation to restore it to the original control target value.

According to such processing, even when both the photovoltaic power generation and the wind power generation are reduced based on the command, the power generation can be rapidly reduced while considering the delay characteristics of the wind power generation equipment 20. can.

FIG. 20 shows an example of control when both photovoltaic power generation output and wind power generation output are increased. The left side of FIG. 20 shows the output change of the generated power (PV output) by the solar power generation equipment 10 and the output change of the generated power (WT output) by the wind power generation equipment 20 in the ideal state. The control contents in the example are shown.

When increasing the power generated by the solar power generation equipment 10 and increasing the power generated by the wind power generation equipment 20, the control unit 110 is smaller than the difference L3 between the current power generated by the wind power generation equipment 20 and the target power generation. The control target value of the photovoltaic power generation facility is temporarily increased by the second correction amount L4.

For example, when receiving a request to increase the interconnection capacity, it may be desirable to increase both the photovoltaic power and the wind power to increase the total value of the power generated at the interconnection point 30 . In such a case, it is advantageous to increase the total value of generated power with as little delay as possible. Considering that it takes time to increase the power generated by the wind power generation facility 20, the control unit 110 temporarily increases the control target value of the power generated by the photovoltaic power generation facility 10. FIG.

FIG. 21 is a flowchart showing an example of processing in the power generation control device 100 when both the photovoltaic power generation output and the wind power generation output are increased. When the control unit 110 increases the power generated by the solar power generation equipment (step S601: YES) and decreases the power generated by the wind power generation equipment (step S602: YES), the processing from step S603 to step S605 is performed. can be executed.

The power meter 32 measures the power currently generated by the solar power generation facility 10, and the power meter 34 measures the power currently generated by the wind power generation facility 20 (step S603). The control unit 110 calculates the difference L3 between the control target value for wind power generation and the current wind power generation output value. Then, the control unit 110 temporarily increases the control target value of the photovoltaic power generation equipment 10 by a second correction amount L4 that is smaller than the difference L3 between the control target value for wind power generation and the current wind power generation power. As the power generated by the wind power generation equipment 20 increases, the control unit 110 decreases the control target value of the temporarily increased power generation to return it to the original control target value.

According to such processing, even when both the solar power generation power and the wind power generation power are increased based on the command, the power generation can be rapidly increased while considering the delay characteristics of the wind power generation equipment 20. can.

The processes shown in FIGS. 18 to 21 can be executed by the same power generation control device 100. FIG. That is, when the control unit 110 reduces the power generated by the solar power generation equipment 10 and reduces the power generated by the wind power generation equipment, the difference L1 between the current power generation and the target power generation of the wind power generation equipment 20 The control target value of the photovoltaic power generation facility is temporarily decreased by the first correction amount L2, which is also large. Then, when increasing the power generated by the solar power generation equipment 10 and increasing the power generated by the wind power generation equipment 20, the control unit 110 sets the difference L3 between the current power generation and the target power generation of the wind power generation equipment 20. The control target value of the photovoltaic power generation facility 10 is temporarily increased by a second correction amount L4 that is smaller than.

When each generated power is increased by the difference L1 between the current generated power and the target generated power of the wind power generation equipment 20 and the first correction amount L2 (D1 shown in FIG. 18) when each generated power is decreased may be larger than the difference (D2 shown in FIG. 20) between the difference L3 between the current generated power and the target generated power of the wind power generation equipment 20 in , and the second correction amount L4. That is, when each generated power is to be decreased, it is greatly decreased, and when each generated power is to be increased, it is less likely to exceed the interconnection capacity.

In addition, when decreasing the power generated by the solar power generation equipment 10 and increasing the power generated by the wind power generation equipment 20, the solar power generation equipment 10 may be executed to delay the reduction of the generated power.
