[0068] In the second aspect of the present invention, in order to solve the shortcoming of the prior art that the energy supply of popular science devices depends on the mains, a photovoltaic microgrid power generation control method based on cadmium telluride is provided. The power generation control method is applied to a photovoltaic microgrid power generation power device based on cadmium telluride, so that the power device is separated from the mains or civil power facilities to achieve complete self-sufficiency.

[0070] In this embodiment, in order to facilitate understanding of how to determine the execution operation information of the actuator and the operation information of the power storage group 61, the following description is made here. The method of separately determining the execution operation information of the actuator and the operation information of the power storage group 61 includes: according to the layout information of the power generation glass 2, respectively collecting the solar radiation in the first time sequence and the second time sequence, and determining the total power generation of the power generation glass 2 in the first time sequence and the second time sequence; that is, by collecting the solar radiation in two different time periods, the total power generation of the power generation glass 2 in the current two different time periods can be determined. Then, according to the total power generation of the power generation glass 2 in the first time sequence and the second time sequence, the execution operation information of the actuator in the first time sequence and the second time sequence is obtained respectively; at the same time, according to the execution operation information of the actuator in the first time sequence and the second time sequence, the operation information of the power storage group 61 is determined respectively. That is, the rotation speed of the actuator and the charging and discharging work of the power storage group 61 can be determined according to the total power generation of the power generation glass 2.

[0071] In this embodiment, in order to further understand how to determine the execution operation information of the actuator and the operation information of the power storage group 61, the following example is given. Specifically, the method of separately determining the execution operation information of the actuator (transmission member 63) and the operation information of the power storage group 61 also includes:

[0072] The change in ambient photon flux caused by the change in solar radiation is: Formula (1),

[0073] In formula (1): - ambient photon flux under lighting conditions, ;

[0074] - Solar geometry factor;

[0075] -Planck constant, ;

[0076] -speed of light in vacuum, ;

[0077] - Photon energy, ;

[0078] -Boltzmann constant, ;

[0079] - Solar radiation semiconductor temperature, unit ;

[0080] The volt-ampere characteristic equation of an ideal solar cell is:

[0081] Formula (2),

[0082] In formula (2): -Boltzmann constant, ;

[0083] - Temperature, unit ;

[0084] - Voltage, unit ;

[0085] -Electron charge, unit ;

[0086] -Reverse saturation current, unit ;

[0087] -Short circuit current, unit ;

[0088] -Dark current, unit ;

[0089] The current produced by an ideal solar cell is:

[0090] Formula (3),

[0091] In formula (3): -Current, unit ;

[0092] -Current density, unit ;

[0098] -Armature circuit current, unit ;

[0099] -Armature circuit resistance, unit ;

[0100] - Motor constants;

[0101] -Magnetic flux, unit ;

[0102] That is, under different solar radiation levels, the solar photon flux changes, causing the number of electrons in the battery inside the photovoltaic module to change. The current formed by the movement of electrons changes synchronously, causing the battery outlet voltage to change, thereby changing the motor speed when the battery is running under load.

[0103] Specifically, in order to make it easier to understand how different solar radiation affects the change of motor speed, the following example is given. Specifically, 12 pieces of cadmium telluride power generation glass are connected in 1 series and 12 parallels, with a single piece peak power of 39Wp and a total power of 468Wp. This example is given under standard irradiance of 1000W / ㎡, 25℃, and air quality AM1.5.

[0104] Assuming that in the first time sequence, the solar radiation reaches 200W / ㎡ at 8 o'clock, according to equations (1) to (4), we can get:

[0105] = ,

[0106] ,

[0107] ,

[0108] 6.7rpm,

[0109] At this time, the rotation speed of the transmission member 63 is 6.7 rpm.

[0110] Assuming that in the second time sequence, the solar radiation reaches 600W / ㎡ at 10 o'clock, according to equations (1) to (4), we can get:

[0111] = ,

[0112] ,

[0113] ,

[0114] =20rpm,

[0115] At this time, the rotation speed of the transmission member 63 is 20 rpm.

[0116] When the total horizontal irradiance reaches 900W / ㎡ at 13 o'clock, according to equations (1) to (4), we can get:

[0117] = ,

[0118] ,

[0119] ,

[0120] ,

[0121] At this time, the rotation speed of the transmission member 63 is 30 rpm.

[0122] It can also be assumed that when the solar radiation reaches 400W / ㎡ at 17:00, according to equations (1) to (4), we can obtain:

[0123] = ,

[0124] ,

[0125] ,

[0126] =13.3rpm,

[0127] At this time, the rotation speed of the transmission member 63 is 13.3 rpm.

[0128] In the third aspect of the present invention, in order to solve the disadvantage of the prior art that the energy supply of the popular science device depends on the mains, a photovoltaic microgrid power generation control system based on cadmium telluride is provided, and the control system also includes: a charge and discharge control module and a voltage stabilizing module, the charge and discharge control module is electrically connected to the power storage group 61 and the power generation glass, respectively, and the charge and discharge control module is used to control the charge and discharge of the power storage group 61. The voltage stabilizing module is electrically connected to the charge and discharge control module, and the voltage stabilizing module is used to control the charge and discharge current and voltage of the power storage group 61.

[0129] In some embodiments, the control system can communicate using any currently known or future developed network protocol such as HTTP (Hyper Text Transfer Protocol), and can be interconnected with any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network ("LAN"), a wide area network ("WAN"), an internet (e.g., the Internet), and a peer-to-peer network (e.g., an ad hoc peer-to-peer network), as well as any currently known or future developed network.

[0130] The functions described above herein may be performed at least in part by one or more hardware logic components.
