A solar power generation system according to one aspect of the present invention includes a solar power generation device group that is arranged by a complex array solar power generation device, and the solar power generation device includes a concentrating solar power generation panel, and a support device for supporting the posture of the solar power generation panel to control the posture; and a control unit having information related to the wind of the place provided by the solar power generation device group, and the plurality of solar photovoltaic power generation devices The posture of the solar power generation panel is to be given to the support device; and in the case where the solar power generation panel that requires a predetermined retraction posture is required according to the above information, the control unit takes the sun in the retracted posture. The number of photovoltaic panels is increased in stages to the necessary number.

Moreover, the attitude control method of the solar power generation panel according to the present invention is a combination of a solar power generation device that supports the concentrating solar power generation panel so as to be able to control the posture thereof by the support device. The attitude control method of the solar power generation panel executed by the control unit that controls the posture integration of each of the photovoltaic power generation panels in the photovoltaic power generation device group, and the solar power generation device group is provided. In the case where the solar power generation panel in which the predetermined retreat posture is necessary according to the above information is present, the number of the solar power generation panels in the retracted posture is increased to the necessary number. In the state in which the solar power generation panel having the above-described retracted posture is present, based on the above information, the number of the solar power generation panels that adopt the retracted posture is reduced in a stepwise manner without taking the retracting posture.

[Problems to be Solved by the Invention] In order to track the sun, the concentrating solar power generation panel is supported by one pillar, for example, and the light receiving surface of the entire panel is large. Therefore, a large load is applied to the pillar when the wind pressure is received. . If the pillar is extremely strong, it can sufficiently withstand a large load, but in consideration of cost considerations, an appropriate strength is actually selected. Even in the case of a sunny day, when a strong wind blows on the panel, based on the safety considerations of the device, the temporary movement is made to the retreat posture (horizontal posture), and after the wind is stopped, the original sun tracking posture is restored, and control is performed accordingly. In the retracted posture, the wind pressure can be avoided as much as possible by making the panel horizontal.

However, in a large-scale solar power generation system, for example, when all the panels are in the retracted posture at the same time, the characteristics of the concentrating solar power generation cannot be generated due to a large deviation of the optical axis. That is, the power generation amount of several tens of MW to several hundreds of MW suddenly becomes zero. In the case of a large metropolitan area with large demand, the capacity of the power grid is large, and the supply and demand adjustment capability is large, so there is no particular problem. However, most of the high-intensity areas that are suitable for installing a solar power generation system are remote areas such as sand deserts. In such a place, the capacity of the entire power grid is often small. In this case, fluctuations of several tens of MW to several hundreds of MW may have a large impact on the regional power grid.

On the other hand, power companies often adjust the amount of power generated as needed. However, in the solar power generation system described above, even if it is sunny, there is a possibility that the amount of power generation suddenly becomes zero due to strong wind, and the prediction of the amount of power generation is difficult. When the amount of power generation suddenly becomes zero, the electric power company must perform, for example, emergency control of power generation such as thermal power generation to obtain a balance between supply and demand of electric power. This move has difficulty in responding to the power company.

In view of the above, an object of the present invention is to reduce the influence on a power grid in a solar power generation system using concentrating solar power generation even when a strong strong wind is blown in.

[Effects of the Present Invention] According to the present disclosure, in a solar power generation system using concentrating solar power generation, even when a strong strong wind is blown in, the influence on the power grid can be alleviated. [Important of the embodiment]

The gist of the embodiment of the present invention includes at least the following.

(1) The solar power generation system includes a solar power generation device group that is arranged by a complex array solar power generation device, and the solar power generation device includes a concentrating solar power generation panel, and the solar power generation panel a support device for supporting the posture of the photovoltaic power generation panel to control the posture; and a control unit having the above-mentioned information in each group of the solar photovoltaic power generation device according to information related to the wind of the place where the photovoltaic power generation device group is installed a function of the posture of the solar power generation panel to be given to the support device; and if the solar power generation panel in which a predetermined retraction posture is necessary according to the above information exists, the control unit takes the sun in the retreat posture The number of photovoltaic panels is increased in stages to the necessary number.

In such a solar power generation system, when some or all of the solar power generation panels need to adopt a retreat posture based on strong winds, the plurality of solar power generation panels are not simultaneously taken back, but the number of retreat postures is increased in stages. To the necessary number. Therefore, it is possible to prevent the rapid decrease of the generated electric power and to alleviate the influence on the electric power network.

(2) In the solar power generation system of (1), when the solar power generation panel having the above-described retracted posture exists, after the state, the information is not required to take the retreat posture. The control unit may reduce the number of the solar power generation panels in the retracted posture in a stepwise manner. In this case, for example, when the retreat posture is adopted, when the strong wind is stopped and the retraction posture is not required, the number of solar power generation panels that adopt the retreat posture is reduced in a stepwise manner and returned to the original posture. Therefore, it is possible to prevent the rapid increase of the generated electric power, and it is also possible to alleviate the influence brought to the electric power grid.

(3) In the solar power generation system of (1), in the solar power generation device group, the mechanical strength of the support device is mixed in a plurality of types, and the solar power generation panel in the retracted posture is required to be based on the information. In the presence of the above, the control unit may increase the number of the solar power generation panels in the retracted posture to a necessary number in a stepwise manner in which the intensity is lower. At this time, the solar power generation panel of the support device having a lower strength can be protected from strong winds by being in a retreating posture earlier. The solar power panel of the higher strength support device may not need to adopt a retreat posture corresponding to the intensity of the wind. In this way, the strength of the wind and the strength of the support device are taken into consideration to take the retreat posture, and the entire solar power generation device group can take appropriate retreat while avoiding the necessary power generation capability.

(4) In the solar power generation system according to any one of (1) to (3), in addition to the solar power generation device group, a solar power generation device equipped with a crystal solar power generation module may be provided in parallel. At this time, for example, by taking the horizontal retracting posture with the light receiving surface facing upward, it is possible to obtain a constant generated electric power with less equipment.

(5) On the other hand, from the viewpoint of the method, a posture control method for providing a solar power generation panel is provided, and solar power generation by supporting the concentrating solar power generation panel in a manner that can control its posture is supported by the support device. The posture control method of the solar power generation panel executed by the control unit that controls the posture integration of each of the photovoltaic power generation panels in the photovoltaic power generation device group is obtained by the above-described apparatus In the case where the solar power generation panel in which the predetermined retreat posture is necessary in accordance with the above-mentioned information, the information on the wind power generation panel in the retreat posture is the number of stages of the solar power generation panel When the above-described solar power generation panel is in a state in which the above-described retreat posture is present, according to the above information, when the retraction posture is unnecessary, the solar power generation panel in the retracted posture is adopted. The number of stages is reduced.

In the attitude control method of the solar power generation panel, when some or all of the solar power generation panels need to adopt the retreat posture based on the strong wind, the plurality of solar power generation panels are not simultaneously taken back, but the retracted posture is adopted. The number of stages is increased to the necessary number. Therefore, it is possible to prevent the rapid decrease of the generated electric power and to alleviate the influence brought to the electric power grid. In addition, when the retreat posture is adopted, the strong wind is stopped and the retracted posture is not required, and the number of solar power generation panels in the retracted posture is reduced in a stepwise manner and the original posture is restored. Therefore, it is possible to prevent the rapid increase of the generated electric power, and it is also possible to alleviate the influence brought to the electric power grid.

[Details of Embodiments] Hereinafter, a solar power generation system and a posture control method of a solar power generation panel according to embodiments of the present invention will be described with reference to the drawings.

<First Embodiment> "Photovoltaic Power Generator" FIG. 1 and FIG. 2 are perspective views of a group of concentrating solar power generators viewed from the light-receiving surface side and the back surface side, respectively. In FIG. 1, the photovoltaic power generation device 100 includes a solar power generation panel 1 that is continuous on the upper side and has a shape in which the lower side is divided into left and right sides, and a supporting device 2. The solar power generation panel (array) 1 is configured by arranging the concentrating solar power generation modules 1M in parallel on the gantry 11 (FIG. 2) on the back side. In the example of FIG. 1 , the solar power generation panel 1 is configured by, for example, an aggregate of a total of 200 concentrating solar power generation modules 1M.

The support device 2 includes a support 21, a susceptor 22, a 2-axis drive unit 23, and a horizontal shaft 24 (FIG. 2) serving as a drive shaft. In the pillar 21, the lower end is fixed to the base 22, and the upper end is provided with a two-axis drive unit 23. An electrical box 13 (FIG. 2) for electrical connection or circuit accommodation is provided in the vicinity of the lower end of the pillar 21.

In Fig. 2, the susceptor 22 is firmly embedded in the ground in a state visible only above. When the susceptor 22 is buried in the ground, the pillar 21 is vertical and the horizontal shaft 24 is horizontal. The two-axis drive unit 23 can rotate the horizontal axis 24 in two directions of an azimuth angle (an angle centering on the pillar 21) and an elevation angle (an angle centering on the horizontal axis 24). The horizontal shaft 24 is fixed in such a manner that the reinforcing member 12 that is reinforced with the fixed gantry 11 is orthogonal to each other. Therefore, if the horizontal shaft 24 is rotated in the azimuth or elevation direction, the solar power generation panel 1 is also rotated in this direction.

1 and 2 show the support device 2 that supports the solar power generation panel 1 by one pillar 21, but the configuration of the support device 2 is not limited thereto. In short, it is sufficient that the solar power generation panel 1 is movably supported by the two axes (azimuth angle, elevation angle).

FIG. 3 is a connection diagram showing an outline of an electrical connection relationship as an example. A drive control unit 3 is provided, for example, in the electrical box 13. The drive control unit 3 drives the motor 23a for driving the azimuth angle and the motor 23e for driving the elevation angle so that the solar power generation panel 1 performs the tracking operation so as to face the sun. The usual tracking operation is performed locally for each solar power generation device 100.

On the other hand, the signal of the posture control may be supplied to the drive control unit 3 by the upper control unit 7. The signal from the posture control of the control unit 7 is prioritized over the local tracking operation performed by the solar power generation device 100. The wind speed of the place where the solar power generation device 100 is installed is detected by the wind speed sensor 7a. The output detected by the wind speed sensor 7a is supplied to the control unit 7. The wind speed sensor 7a can also be said to be part of the control unit 7. However, the control unit 7 may be provided separately from the solar power generation device 100. The control unit 7 includes, for example, a computer, and implements a necessary control function by causing a computer to execute a software (computer program). The software is stored in a memory device (not shown) of the control unit 7.

Further, the output (direct current) of the solar power generation panel 1 is converted into AC power via the power conditioner 6, and the AC power is transmitted to a power converter (not shown). The power conditioner 6 is provided, for example, corresponding to each group of the photovoltaic power generation device 100. The AC power based on the respective outputs is transmitted from the complex array solar power generation device 100 to the variable electric machine.

For example, the solar power panel 1 at night is in a horizontal posture. At the same time as the sunrise, the solar power generation panel 1 is in a substantially vertical posture close to the state of FIG. 1 toward the direction of the sun rising from the horizon. Then, the azimuth and the elevation are operated in such a manner as to track the movement of the sun, and the light receiving surface is always placed in a posture facing the sun. At the time of the sunset, the solar power generation panel 1 is again in a substantially vertical posture close to the state of FIG. 1 toward the direction of the sun that has entered the horizon. The solar power generation panel 1 after the day is in a horizontal posture. If there is no strong wind blowing in, carry out such an action on a daily basis.

4 is a perspective view showing an example of a state in which the light receiving surface of the solar power generation panel 1 faces the sun. In addition, the solar power generation panel 1 in the retracted posture is horizontal, for example, and the wind easily passes, and the wind pressure is not easily received.

"Sunlight Power Generation System" FIG. 5 is a schematic diagram showing a state of the solar power generation system 300 in which the solar power generation device 100 is arranged in parallel, for example, in a group of eight groups of solar power generation devices 200 in total. The control unit 7 is connected to be communicable with all of the photovoltaic power generators 100, and can control the posture of each photovoltaic power generation panel 1 individually and collectively. As described above, the posture control of the control unit 7 is performed in preference to the local solar tracking operation of each of the photovoltaic power generators 100.

<<Retraction in Strong Wind>> Here, for example, it is assumed that all of the 64 solar power generation apparatuses 100 are of the same type, and the strength of the support apparatus 2 is also the same. 6 to 9 show the solar power generation device 100 in a simplified manner and indicated by square marks. The white mark is used to track the posture of the sun, and the mark with the slash is a retreat posture.

For example, it is assumed that the local wind speed set by the solar power generation device group 200 reaches the level of "strong wind" that requires a retreat posture. At this time, first, as shown in FIG. 6, the control unit 7 moves the solar power generation device 100 of one column on the left side of the figure from the posture of tracking the sun to the retracted posture, for example. That is, the retreat posture is 8 groups, and the remaining 56 groups are postures for tracking the sun.

Next, in FIG. 7, the control unit 7 further moves the solar power generation device 100 of the second row from the posture of tracking the sun to the retracted posture. That is, the retreat posture is increased to 16 groups, and the remaining 48 groups are postures for tracking the sun. If the strong wind continues, the 1 column is staged to the retreat posture. In Fig. 8, 56 is the retreat posture, and only 8 groups are the postures for tracking the sun. Finally, in FIG. 9, all the solar power generation panels 1 are in a retracted posture.

The actual wind system is blown in at random, so it is very difficult to move in the order of Figure 6 to Figure 9. For example, in the middle of the state of FIGS. 6 to 9, after the wind is stopped, the original situation can be restored. However, even if all of the last photovoltaic power generation panels 1 are in the retracted posture, they are all at the same time as the retracted posture, and the number of transitions to the retracted posture is increased to the necessary number in a stepwise manner.

The relationship between the posture of the solar power generation panel 1 and the generated electric power will be described. The solar power generation panel 1 composed of the concentrating solar power generation module 1M is configured to condense sunlight and introduce it into an optical system of a small power generating element. Therefore, the amount of power generation becomes zero when the posture is retracted.

FIG. 10 is a diagram showing changes in power generation power when the entire group of the strong wind photovoltaic power generation device group 200 is simultaneously in the retracted posture for comparison. At this time, the generated electric power rapidly becomes zero at the same time as the start of the retreat. That is, it has a big impact on the power grid.

FIG. 11 is a diagram showing changes in generated electric power when the stage type is in the retracted posture in the manner of the above-described series of the above-described FIGS. 6 to 9 . That is, the generated electricity is reduced in eight stages. Therefore, the impact on the power grid can be alleviated. Further, in this case, the support device 2 needs to have a strength capable of resisting strong wind during at least the time T until the eight stages are lowered.

FIG. 12 is a diagram showing changes in the generated electric power when the photovoltaic power generator 100 is stepped in a group and is kept as short as possible in one stage, and is moved to the retracted posture. The characteristic of the reduction of the generated electric power at this time is close to a straight line, but it is still a step change.

In the above-described example (FIGS. 6 to 9), the number of the solar power generation panels 1 that are in the retracted posture is increased from the left side of the figure. However, this is merely an example for convenience of explanation, and it may be used from which column. Further, it is also possible to make the predetermined number a retreat posture in a random manner without being tied to the columns. In other words, it is sufficient to increase the number of solar photovoltaic panels 1 in the retracted posture to the necessary number.

Further, in the case where the strong wind is stopped, for example, in the order of FIG. 9, FIG. 8, FIG. 7, and FIG. 6, the number of the solar power generation panels 1 that return to the original solar tracking posture may be increased in a stepwise manner. In other words, when the solar power generation panel 1 having the retracted posture is present, the control unit 7 reduces the solar power generation panel that adopts the retracted posture in a step-by-step manner when the retraction posture is not required according to the wind information. The number of 1. In this manner, when it is not necessary to take a retreat posture based on the strong wind stop, the number of the solar power generation panels 1 in the retracted posture is reduced in a stepwise manner and the original posture is restored. Therefore, it is possible to prevent the rapid increase of the generated electric power, and it is also possible to alleviate the influence brought to the electric power grid.

<Second Embodiment> Next, in the solar power generation system according to the second embodiment, the appearance of the photovoltaic power generation device 100 is substantially the same as that of FIG. 1, but the strength of the support device 2 that supports the load when receiving the wind pressure is mixed. Plural categories. For example, a pillar 21 having a plurality of types of strengths by changing the diameter of the pillar 21, the thickness of the metal, the material, and the like is prepared. Further, the support device 2 having a plurality of types of strengths may be prepared by varying the degree of reinforcement of the portion where the stress tends to concentrate.

FIG. 13 shows an example of arranging 36 sets of solar power generation apparatuses 100, for example. Among the 36 sets, the strength of the support device 2 is set to, for example, six stages, and each of the six sets is six sets. The solar power generation device 100 is classified into A, B, C, D, E, and F in order of high intensity, and the critical value for moving to the retracted posture when the strong wind is strong, for example, the critical value of the highest intensity A is set to wind speed of 20 m/s. The above is continuous for 10 seconds. On the contrary, the critical value of F with the lowest intensity is set to a wind speed of 14 m/s or more and continuous for 8 seconds. B, C, D, and E are set to the intensity between A and F. That is, the relationship between the strengths is set to A>B>C>D>E>F. Their values are only an example of the description. Further, the arrangement of A to F in Fig. 13 is also an example for convenience of explanation.

For example, if the wind speed reaches the level of the critical value of F, F enters the retracting action. If the wind speed reaches the level of the critical value of E, F and E enter the retracting action. If the wind speed reaches the level of the critical value of D, F, E, and D enter the retracting action. If the wind speed reaches the level of the critical value of C, F, E, D, and C enter the retracting action. If the wind speed reaches the level of the critical value of B, F, E, D, C, and B enter the retracting action. If the wind speed reaches the level of the critical value of A, then F~A all enters the retracting action.

The actual wind suddenly reaches the critical value of A from the state of the weak wind, but gradually becomes stronger. Therefore, at least the occurrence of at least a few suddenly occurs as a retreat posture, and the number of transitions to the retreat posture is increased step by step. Thereby, it is possible to prevent the generated power from suddenly becoming zero. That is, the impact on the power grid can be alleviated. When the strong wind stops and recovers from the retreat posture, the number of responses is also increased in stages, so that the rapid increase of the generated power can be prevented, and the influence brought to the power grid can be alleviated.

In the second embodiment, in the solar power generation device group 200, the mechanical strength of the support device 2 is mixed in a plurality of types, and when the retraction posture is required, the retraction posture is adopted in a stepwise manner in the order of the lower strength. The necessary number. In this case, the solar power generation panel 1 of the support device 2 having a lower strength can be protected from strong winds by being in a retracted posture earlier. The solar power generation panel 1 of the support device 2 having a higher strength can take the retraction posture according to the strength of the wind. In this manner, the strength of the wind and the strength of the support device 2 are taken into consideration, and the retreat posture is adopted, and the entire photovoltaic power generation device group 200 can take appropriate retreat and the power generation capability of the above-described power generation capability can be avoided.

<Other measures common to the respective embodiments> Other measures that are common to the above-described respective embodiments can be added. For example, the following can be considered. In addition to the photovoltaic power generation device group 200 in which the solar power generation panel 100 of the concentrating type is mounted, a solar power generation device in which a crystal ray solar power generation module is mounted may be provided in parallel. The merging method may be, for example, a plurality of groups may be mixed in the solar power generation device group 200, or may be provided adjacent to each other. Regarding the solar power generation device equipped with the crystal ray solar power generation module, the support device 2 is the same, and the retraction posture adopted is also the same.

In this way, when a solar power generation panel equipped with a crystal solar power generation module is provided in parallel, for example, by adopting a horizontal retraction posture with the light receiving surface facing upward, a constant amount of generated electric power can be obtained in a small amount. That is, even if the retracted posture is taken, the generated electric power does not become zero. Therefore, even if all the solar power generation panels adopt the retracted posture, the influence brought to the power grid can be alleviated.

<Consolidation> As described in detail above, the solar power generation system 300 includes: a solar power generation device group 200; and a control unit 7 having a plurality of pieces of information related to the wind of the place provided by the solar power generation device group 200 The posture to be taken by the solar power generation panel 1 among the photovoltaic power generation devices 100 is indicated to the function of the support device 2. When there is a solar power generation panel 1 in which a retreat posture is required depending on the wind information, the control unit 7 increases the number of solar photovoltaic panels 1 in the retracted posture to a necessary number.

According to such a solar power generation system 300, when some or all of the solar power generation panels 1 need to adopt a retreat posture based on strong winds, the plurality of solar power generation panels 1 are not simultaneously taken back, but the number of retracted postures is taken. Increase the phase to the necessary number. Therefore, it is possible to prevent the rapid decrease of the generated electric power and to alleviate the influence brought to the electric power grid.
