[0002] As the country promotes the green energy transformation, renewable clean energy represented by solar power generation, wind power generation, and hydropower accounts for an increasingly higher proportion of power generation sources. Compared with traditional thermal power generation, renewable clean energy power generation not only has environmental advantages such as low carbon emissions, but also has a higher cost advantage. However, for solar power generation, its power generation capacity depends on weather conditions, and it is impossible to achieve stable power generation, and there are fluctuations; and the main power generation time of solar power generation may not be the same as the main power consumption time of the load equipment. Therefore, for small power systems that use solar power generation, how to store and dispatch the electricity generated by solar power generation to enable the small power system to operate with higher economic benefits is a technical problem that needs to be solved urgently.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below with reference to the accompanying drawings and examples. However, the exemplary embodiments can be implemented in various forms and should not be understood as being limited to the embodiments described herein; on the contrary, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concepts of the exemplary embodiments to those skilled in the art. The same figure marks in the figures represent the same or similar structures, and thus their repeated descriptions will be omitted. The words expressing position and direction described in the present invention are all explained using the accompanying drawings as examples, but changes can be made as needed, and the changes made are all included in the scope of protection of the present invention. The drawings of the present invention are only used to illustrate the relative position relationship and do not represent the true proportions.

[0051] It should be noted that specific details are described in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The subsequent description of the specification is a preferred embodiment of the present application, but the description is for the purpose of illustrating the general principles of the present application and is not intended to limit the scope of the present application. The scope of protection of the present application shall be determined by the definition of the attached claims.

[0052] The power supply scheduling method and related hardware provided by the embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0053] In a first aspect, an embodiment of the present invention provides a power system, such as Figure 1As shown, it includes: photovoltaic power generation equipment D1, energy storage equipment D2, power supply equipment D3, and dispatching equipment D4. Among them, the power supply equipment D3 is connected to the photovoltaic power generation equipment D1, the energy storage equipment D2, the dispatching equipment D4, the external power grid P, and the load equipment L. The energy storage equipment D2 is also connected to the dispatching equipment D4.

[0054] In the specific implementation process, the photoelectric power generation equipment D1 can be a photoelectric power generation equipment, a photochemical power generation equipment, a photo-induction power generation equipment, a photobiological power generation equipment, or a focused photothermal power generation equipment, a photochimney power generation equipment, or a photothermal power generation equipment. The energy storage equipment D2 can be a chemical battery equipment, a pumped storage power station, etc. The power supply equipment D3 can include an inverter that converts the direct current generated by the photoelectric power generation equipment into alternating current, a transformer that converts the voltage of the electric energy generated by the external power grid, a switch device that controls the transmission of electric energy from different sources, a filter that controls power stability, a reactive power compensation device, etc., which can be implemented in the form of a photoelectric storage integrated cabinet.

[0055] In the specific implementation process, the dispatching device D4 controls the power supply device D3 to provide the electric energy generated by the photovoltaic power generation device to the load device L for consumption and to the energy storage device D2 for charging, and provides the electric energy provided by the external power grid P to the load device L for consumption and to the energy storage device D2 for charging, and provides the electric energy released by the energy storage device D2 to the load device L for consumption. In addition, the dispatching device D4 controls the energy storage device D2 to discharge the energy storage device D2 to the power supply device D3, and then supplies power to the load device L through the power supply device D3. The dispatching device D4 controls the energy storage device D2 to control the charging of the energy storage device D2, for example, to prevent the energy storage device D2 from being overcharged.

[0056] The working principle of the above power system is explained below by taking the process of the dispatching device D4 controlling each device in the above power system.

[0057] In a second aspect, an embodiment of the present invention further provides a power supply scheduling method, which is applied to the scheduling device D4 described in the first aspect. Figure 2 As shown, the power supply scheduling method specifically includes the following steps:

[0058] S100, controlling the solar power generation equipment to supply power to the load equipment.

[0059] In a specific implementation process, the solar power generation device can be controlled to supply power to the load device by controlling the power supply device D3.

[0060] In a specific implementation process, if the solar power generation device is not generating electricity (for example, when the solar power generation device is in a dark environment at night), the current solar power generation power is actually zero.

[0061] Since the photovoltaic power generation power of photovoltaic power generation equipment is affected by the lighting conditions and cannot be controlled manually, there may be a situation where the current photovoltaic power generation power of the photovoltaic power generation equipment does not match the current power consumption of the load equipment. For example, the current photovoltaic power generation power of the photovoltaic power generation equipment is greater than the current power consumption of the load equipment. At this time, the power generated by the photovoltaic power generation equipment is more than the power consumed by the load equipment; for another example, the current photovoltaic power generation power of the photovoltaic power generation equipment is less than the current power consumption of the load equipment. At this time, the power generated by the photovoltaic power generation equipment is not enough to meet the power consumption of the load equipment. The following describes the additional power supply scheduling steps when the current photovoltaic power generation power of the photovoltaic power generation equipment is not equal to the current power consumption of the load equipment.

[0062] (1) The current solar power generation power of the solar power generation equipment is greater than the current power consumption of the load equipment:

[0063] In step S100, the solar power generation device supplies power to the load device with the current power consumption.

[0064] While executing step S100, the following steps are also executed:

[0065] S200, controlling the solar power generation equipment to charge the energy storage equipment with the power difference between the current solar power generation power and the current power consumption.

[0066] During the specific implementation process, the scheduling device can distribute the electric energy generated by the photovoltaic power generation equipment by controlling the power supply equipment, provide the electric energy corresponding to the current power consumption to the load device for consumption, and provide the electric energy corresponding to the power difference between the current photovoltaic power generation power and the current power consumption to the energy storage device for charging.

[0067] In the specific implementation process, when controlling the solar power generation equipment to charge the energy storage device with the power difference between the current solar power generation power and the current power consumption, charging is stopped when the storage capacity of the energy storage device reaches the upper storage capacity limit of the energy storage device to avoid damaging the energy storage device.

[0068] (2) The current solar power generation power of the solar power generation equipment is less than the current power consumption of the load equipment:

[0069] In step S100, the solar power generation device supplies power to the load device with the current power generation power.

[0070] While executing step S100, step S300 is also executed.

[0071] S300, controlling the energy storage device to supply power to the load device with the target power supply as the upper limit of the power supply during the current control period.

[0072] Among them, the target power supply is determined based on the day and night conditions corresponding to the current control period, the storage capacity of the energy storage device at the starting time of the current control period, the predicted solar power generation of the solar power generation equipment in the next control period of the current control period, and the predicted power consumption of the load equipment in the next control period of the current control period.

[0073] In an embodiment of the present invention, the whole day is divided into multiple control periods for segmented control. Among them, each control period can be of equal length (for example, the whole day is divided into 12 control periods, each control period is 2 hours); or, each control period can be of unequal length (for example, the whole day is divided into 6 control periods, which are 6:00-7:59, 8:00-10:59, 11:00-12:59, 13:00-15:59, 16:00-17:59, 18:00-21:59, 22:00-5:59), and the embodiment of the present invention does not make too many restrictions here. In addition, the time corresponding to the control period can also be adjusted according to the sunrise and sunset time of the location of the solar power generation equipment and the time-of-use electricity price of the external power grid. For example, for the same location, the control period in winter is different from that in summer.

[0074] After completing the division of the control time periods, you will get daytime control time periods that are all in the daytime state, nighttime control time periods that are all in the nighttime state, and control time periods that span day and night in which sunrise or sunset may occur in a certain control time period. A control time period that spans day and night does not have sunrise or sunset at the start or end time of the control time period. For a control time period that spans day and night, the day and night state corresponding to the control time period that spans day and night can be determined based on the time ratio of day and night, that is, whether the control time period specifically belongs to a daytime control time period or a nighttime control time period. For example, if the sun sets at 18:30 at the location of the solar power generation equipment on a certain day, then for the control time period from 18:00 to 21:59, the control time period belongs to the nighttime control time period on that day.

[0075] Optionally, the predicted solar power generation amount of the solar power generation equipment in the next control period can be determined according to the weather forecast information corresponding to the location of the solar power generation equipment in the next control period.

[0076] If the weather forecast information predicts that there will be precipitation at the location of the solar power generation equipment in the next control period, the predicted solar power generation is determined to be a preset value (for example, the predicted solar power generation is determined to be 0, or the predicted solar power generation is determined to be a value close to 0).

[0077] If the weather forecast information predicts that there will be no precipitation at the location of the photovoltaic power generation equipment in the next control period, the predicted photovoltaic power generation is determined based on the predicted cloud cover of the weather forecast information. Among them, the predicted photovoltaic power generation is linearly negatively correlated with the predicted cloud cover. The cloud cover is the ratio of the cloud area to the sky area. For example, let the predicted photovoltaic power generation of the photovoltaic power generation equipment in the next control period be E1, and the predicted cloud cover be C. Then:

[0078] E1=k·C+b

[0079] Wherein, k and b are parameters obtained by fitting calibration, and k<0.

[0080] Optionally, the predicted power consumption of the load device in the next control period is determined according to the time corresponding to the next control period. The predicted power consumption of the load device in the next control period is in a sinusoidal relationship with the time corresponding to the control period. For example, let the predicted power consumption of the load device in the next control period be E2, and the mark time corresponding to the control period (the mark time can be set to the start time, end time, midpoint time, etc. of the control period) be t. Then:

[0081]

[0082] Among them, e1, ω, e2 is the parameter obtained by fitting calibration.

[0083] In the specific implementation process, in the process of controlling the energy storage device to supply power to the load device with the target power supply as the upper limit of the power supply during the current control period, when the sum of the energy storage power supply of the energy storage device to the load device and the current solar power generation power is less than the current power consumption, the dispatching device also controls the external power grid to supply power to the load device. Among them, the current external power supply power of the external power grid to the load device satisfies: the sum of the current solar power generation power, the energy storage power supply power, and the current external power supply power is equal to the current power consumption, so as to achieve the balance of power supply and demand of the power system.

[0084] In this way, the power supply scheduling method provided by the embodiment of the present invention can store the surplus electric energy of solar power generation while supplying the electric energy generated by solar power generation to the load device for consumption. Therefore, when solar power generation cannot meet the electricity demand of the load device, the electric energy stored in advance can be provided to the load device for consumption, thereby reducing the load device's use of electric energy provided by the external power grid, thereby effectively reducing the electricity cost of the load device and realizing peak shaving and valley filling of solar power generation.

[0085] Specifically, Figure 3 As shown, step S300 may include the following steps:

[0086] S310: Determine whether the current control period belongs to the daytime control period or the nighttime control period.

[0087] If the current control period is the daytime control period, execute step S410; if the current control period is the nighttime control period, execute step S510.

[0088] If the current control period is the night control period, then accordingly:

[0089] S510: Determine whether the current control period belongs to the first electricity price period.

[0090] The electricity price period includes a first electricity price period and a second electricity price period, and the electricity price of the external power grid in the first electricity price period is higher than the electricity price in the second electricity price period.

[0091] In the specific implementation process, the external power grid will divide the whole day into multiple electricity price periods according to the power consumption of its load, wherein the period with greater power consumption of the load in the external power grid has a higher power price. For example, the external power grid is divided into three types of electricity price periods, namely, valley period, stable period and peak period, according to the power consumption of its load, wherein the power price of the valley period is lower than that of the stable period, and the power price of the stable period is lower than that of the peak period. Then, the peak period can be used as the first electricity price period in the embodiment of the present invention, the valley period can be used as the second electricity price period in the embodiment of the present invention, and the stable period can be used as the third electricity price period that does not belong to the second electricity price period and the first electricity price period. For another example, the external power grid is divided into 5 levels of electricity price periods, 1 to 5, according to the power consumption of its load, wherein the higher the level of the electricity price period, the higher the electricity price. Then, the 4th level electricity price period and the 5th level electricity price period can be used as the first electricity price period in the embodiment of the present invention, the 1st level electricity price period and the 2nd level electricity price period can be used as the second electricity price period in the embodiment of the present invention, and the 3rd level electricity price period can be used as the third electricity price period that does not belong to the first electricity price period and the second electricity price period.

[0092] If the result of step S510 is yes, step S520 is executed.

[0093] S520: Determine the target power supply as the storage capacity of the energy storage device at the start time of the current control period.

[0094] S530: Determine whether the actual power supply from the energy storage device to the load device during the current control period reaches the target power supply.

[0095] If the result of step S530 is no, execute step S540; if the result of step S530 is yes, execute step S550.

[0096] S540, controlling the energy storage device to supply power to the load device with the target power supply as the upper limit of the power supply during the current control period.

[0097] Furthermore, when the energy storage device supplies power to the load device, the real-time power supply of the energy storage device needs to be adjusted according to the current power consumption of the load device to achieve a balance between power supply and demand of the power system. Figure 5 As shown, the step S540 specifically includes the following steps:

[0098] S541, determine whether the current solar power generation power and the upper limit of the energy storage power supply power of the energy storage device are greater than or equal to the current power consumption.

[0099] If the result of step S541 is yes, execute step S542; if the result of step S541 is no, execute step S543.

[0100] S542, control the energy storage device to supply power to the load device. The energy storage power supplied by the energy storage device to the load device satisfies: the sum of the energy storage power and the current solar power generation power is equal to the current power consumption.

[0101] S543, control the energy storage device to supply power to the load device at the upper limit of the energy storage power supply power, and control the external power grid to supply power to the load device. The current external power supply power of the external power grid to the load device satisfies: the sum of the current solar power generation power, the upper limit of the energy storage power supply power and the current external power supply power is equal to the current power consumption.

[0102] S550, controlling the external power grid to supply power to the load device. The current external power supply power of the external power grid to the load device satisfies: the sum of the current solar power generation power and the current external power supply power is equal to the current power consumption.

[0103] Furthermore, if the result of step S510 is no, that is, the current control period does not belong to the first electricity price period, then the electricity price of the external power grid in the current control period is low, and the target power supply can be set to 0, that is, the energy storage device does not supply power to the load device. At this time, the external power grid is controlled to supply power to the load device (for example Figure 3 As shown in step S550, the electric energy consumed by the load device in a dark environment at night is all provided by the external power grid. Of course, the target power supply amount can also be set to a non-zero value, that is, the energy storage device bears at least part of the electric energy consumed by the load device, and the difference between the electric energy provided by the energy storage device and the electric energy consumed by the load device in a dark environment at night is provided by the external power grid to reduce the use of the electric energy provided by the external power grid. The embodiment of the present invention is not limited in detail here.

[0104] If the current control period is the daytime control period:

[0105] S410, determining a target power supply according to the predicted solar power generation of the solar power generation equipment in the next control period, the predicted power consumption of the load equipment in the next control period, and the storage capacity of the energy storage equipment at the start time of the current control period.

[0106] S420, determining whether the actual power supply of the energy storage device to the load device during the current control period reaches the target power supply.

[0107] If the result of step S420 is no, execute step S430; if the result of step S420 is yes, execute step S440.

[0108] S430: In the current control period, the energy storage device is also controlled to supply power to the load device with the target power supply as the upper limit of the power supply.

[0109] Furthermore, when the energy storage device supplies power to the load device, the real-time power supply of the energy storage device needs to be adjusted according to the current power consumption of the load device to achieve a balance between power supply and demand of the power system. Figure 4 As shown, the step S430 specifically includes the following steps:

[0110] S431, determining whether the sum of the current solar power generation power and the upper limit of the energy storage power supply power of the energy storage device is greater than or equal to the current power consumption.

[0111] If the result of step S431 is yes, execute step S432; if the result of step S431 is no, execute step S433.

[0112] S432, controlling the energy storage device to supply power to the load device, the current energy storage power supplied by the energy storage device to the load device satisfies: the sum of the current solar power generation power and the current energy storage power supply power is equal to the current power consumption.

[0113] S433, control the energy storage device to supply power to the load device at the upper limit of the energy storage power supply power, and control the external power grid to supply power to the load device. The current external power supply power of the external power grid to the load device satisfies: the sum of the current solar power generation power, the upper limit of the energy storage power supply power, and the current external power supply power is equal to the current power consumption.

[0114] S440, controlling the external power grid to supply power to the load device. The current external power supply power of the external power grid to the load device satisfies: the sum of the current solar power generation power and the current external power supply power is equal to the current power consumption.

[0115] Further optionally, the step S300 further includes (not shown in the figure):

[0116] When the current solar power generation power of the solar power generation equipment is less than the current power consumption of the load equipment, if the current control period belongs to the second electricity price period and the target power supply in the current control period is 0, the external power grid is controlled to charge the energy storage device in the current control period.

[0117] In the specific implementation process, when the external power grid is controlled to charge the energy storage device, charging is stopped when the storage capacity of the energy storage device reaches the upper storage capacity limit of the energy storage device to avoid damaging the energy storage device.

[0118] In this way, when the electricity price of the external grid is low, the energy storage device is charged by the external grid when the energy storage device is not supplying power to the load device, so that when the electricity price of the external grid is high, the energy storage device can be charged by releasing the stored electric energy, thereby reducing the load device's use of electric energy provided by the external grid during times of higher electricity prices, thereby effectively reducing the electricity cost of the load device.

[0119] Further optionally, if Figure 3 As shown, after step S550, the following steps are further included:

[0120] S560: Determine whether the current control period belongs to the second electricity price period, and whether the target power supply amount of the current control period is 0.

[0121] If the results of step S560 are all yes, execute step S570; otherwise, execute the corresponding power supply scheduling step at the next moment.

[0122] S570: Determine the predicted light level for the next daytime control period according to the weather forecast information for the location of the solar power generation equipment for the next daytime control period.

[0123] For example, the control periods are: daytime control period ①: 6:00-7:59, daytime control period ②: 8:00-10:59, daytime control period ③: 11:00-12:59, daytime control period ④: 13:00-15:59, daytime control period ⑤: 16:00-17:59, nighttime control period ①: 18:00-21:59, nighttime control period ②: 22:00-5:59. For nighttime control period ① and nighttime control period ②, the next daytime control period is daytime control period ①: 6:00-7:59.

[0124] S580: Determine a target power storage amount according to the predicted light level.

[0125] S590: Control the external power grid to charge the energy storage device with the target storage capacity as the charging target during the current control period.

[0126] In a specific implementation process, the predicted light level of the next daytime control period can be determined according to the weather forecast information corresponding to the next control period at the location of the solar power generation equipment.

[0127] If the weather forecast information predicts that there will be precipitation at the location of the solar power generation equipment during the next daytime control period, the predicted light level is determined to be the lowest level.

[0128] If the weather forecast information predicts that there will be no precipitation at the location of the solar power generation equipment during the next daytime control period, the predicted light level is determined based on the predicted cloud cover of the weather forecast information. The predicted light level is negatively correlated with the predicted cloud cover. For example, the predicted light level corresponds to the predicted cloud cover in the following manner:

[0129] Table 1 Classification of cloud cover information

[0130] Cloud Cover [0,35％) [35％,70％) [70％,100％] Predicted light levels High Level Intermediate Low level

[0131] Accordingly, the target storage capacity can be determined as follows:

[0132] ① If the predicted light level is low, the upper limit of the storage capacity will be used as the target storage capacity.

[0133] If the predicted light level is low, the light conditions in the next daytime control period are expected to be very poor. In this case, when the electricity price of the external grid is low, the external grid is controlled to fully charge the energy storage device to reduce electricity costs.

[0134] ② If the predicted light level is medium, determine the predicted solar power generation of the solar power generation equipment in the next daytime control period, and use the difference between the upper limit of the energy storage capacity of the energy storage equipment and the predicted solar power generation as the target storage capacity.

[0135] If the predicted light level is medium, the light conditions in the next daytime control period are expected to be average, and the solar power generation equipment is expected to provide a certain amount of power to the energy storage equipment, but it cannot fully charge the energy storage equipment. Then the energy storage equipment is controlled to be charged to a state of being not fully charged during the nighttime control period, and the remaining rechargeable capacity of the energy storage equipment is expected to be fully charged by the solar power generation equipment during the next daytime control period, thereby reasonably reducing the energy storage equipment's use of external power grid power during the nighttime control period and reducing electricity costs.

[0136] ③ If the predicted light level is high, the current storage capacity of the energy storage device is used as the target storage capacity.

[0137] If the predicted light level is high, it is expected that the next daytime control period will have sufficient light, and the solar power generation equipment is expected to provide sufficient power for the energy storage equipment to charge to full. Then the energy storage equipment is controlled not to charge during the night control period, thereby minimizing the energy storage equipment's use of external grid power during the night control period and reducing electricity costs.

[0138] In this way, by controlling the charging strategy of the energy storage device during the night time period with low electricity prices according to the weather forecast information of the location of the solar power generation equipment during the next daytime control period, the electricity cost can be reduced as reasonably as possible.

[0139] The predicted solar power generation of the solar power generation equipment in the next control period is recorded as E1, the predicted power consumption of the load equipment in the next control period is recorded as E2, the storage capacity of the energy storage equipment at the start time of the current control period is recorded as E3, and the target power supply is recorded as E0.

[0140] As an optional implementation, the target power supply during the daytime control period can be determined in the following manner:

[0141] ①If E1≥E2, then E0=min(E3,E1-E2).

[0142] For case ①, since the predicted power consumption of the load device in the next control period is small, and the predicted solar power generation of the solar power generation device in the next control period is large, if the energy storage device releases a certain amount of stored energy in the current control period, the energy released in the current control period is expected to be compensated by solar power generation in the next control period. In this way, the min (E3, E1-E2) energy stored in the energy storage device can be released for consumption by the load device in the current control period, and it is expected that it will not affect the energy storage device's power supply to the load device in the night control period.

[0143] ②If E1<E2, then E0=0.

[0144] For situation ②, since the predicted power consumption of the load equipment in the next control period is large, the predicted solar power generation of the photovoltaic power generation equipment in the next control period is insufficient to meet the predicted power consumption demand. Therefore, it is estimated that the energy storage equipment cannot be charged in the next control period. Under the premise that only the photovoltaic power generation equipment is used to charge the energy storage equipment during the day, in order not to affect the energy storage equipment's power supply to the load equipment during the night control period, the energy storage equipment does not supply power to the load equipment during the current control period.

[0145] As another optional implementation, the target power supply during the daytime control period can be determined in the following manner:

[0146] ① If the next control period of the current control period belongs to the second electricity price period, then E0=E3.

[0147] For situation ①, when the power generated by solar power generation is insufficient to meet the power consumption demand of the load device during the current control period, the energy storage device can be controlled to supply power to the load device to reduce the load device's use of power provided by the external power grid, thereby reducing the load device's electricity cost. Since the electricity price of the external power grid is lower during the next control period, it is acceptable to use the power of the external power grid to charge the energy storage device during the next control period. In this way, even if the energy storage device is fully charged with power from the external power grid during the next control period, the cost is still low.

[0148] ② If the next control period of the current control period does not belong to the second electricity price period, and E1≥E2, then E0=min(E3,E1-E2).

[0149] For situation ②, when the power generated by solar power generation in the current control period is insufficient to meet the power consumption demand of the load equipment, the energy storage device can be controlled to supply power to the load equipment to reduce the load equipment's use of power provided by the external power grid, thereby reducing the load equipment's electricity cost. Since the electricity price of the external power grid in the next control period is high, it is not acceptable to use the power of the external power grid to charge the energy storage device in the next control period. The power released by the energy storage device in the current control period should all be charged and provided by the solar power generation device in the next control period. Since the predicted power consumption of the load equipment in the next control period is small, and the predicted solar power generation of the solar power generation device in the next control period is large. In this way, the min (E3, E1-E2) power stored in the energy storage device can be released for consumption by the load equipment in the current control period. This part of the power is expected to be replenished by solar power generation in the next control period, and it is expected that it will not affect the energy storage device's power supply to the load equipment in the night control period.

[0150] ③ If the next control period of the current control period does not belong to the second electricity price period, and E1<E2, then E0=0.

[0151] For situation ③, since the electricity price of the external power grid is high in the next control period, it is unacceptable to use the electricity of the external power grid to charge the energy storage device in the next control period. The electricity released by the energy storage device in the current control period should be charged and provided by the photovoltaic power generation device in the next control period. However, the predicted power consumption of the load device in the next control period is large, while the predicted photovoltaic power generation of the photovoltaic power generation device in the next control period is small. It is expected that the photovoltaic power generation device will not have excess electricity to charge the energy storage device in the next control period. Therefore, in order not to affect the energy storage device's power supply to the load device in the night control period, the energy storage device does not supply power to the load device in the current control period.

[0152] In a third aspect, based on the same inventive concept, an embodiment of the present invention further provides a power supply scheduling device, such as Figure 6 As shown, including:

[0153] The photovoltaic load power supply scheduling module M1 is used to control the photovoltaic power generation device to supply power to the load device with the current power consumption when the current photovoltaic power generation power of the photovoltaic power generation device is greater than the current power consumption of the load device; and to control the photovoltaic power generation device to supply power to the load device with the current photovoltaic power generation power when the photovoltaic power generation power is less than or equal to the current power consumption;

[0160] If the predicted solar power generation is not less than the predicted power consumption, the target power supply is determined to be the minimum value of the difference between the predicted solar power generation and the predicted power consumption and the power storage at the starting time;

[0161] If the predicted solar power generation is less than the predicted power consumption, the target power supply is determined to be 0.

[0162] As another optional implementation, if the current control period is a daytime control period, the target power supply is determined by:

[0165] If the next control period of the current control period does not belong to the second electricity price period, and the predicted solar power generation is less than the predicted power consumption, the target power supply is determined to be 0.

[0166] The electricity price of the external power grid in the first electricity price period is higher than the electricity price in the second electricity price period.

[0167] Optionally, the device further comprises:

[0168] The external electric energy storage charging scheduling module M4 is used to control the external power grid to charge the energy storage device in the current control period when the current solar power generation power is less than the current power consumption power, if the current control period belongs to the second electricity price period, and the target power supply in the current control period is 0.

[0169] Further optionally, the external electric energy storage charging scheduling module M4 is specifically used for:

[0170] If the current control period belongs to the night control period and the second electricity price period, and the target power supply in the current control period is 0, then the predicted light level in the next daytime control period is determined according to the weather forecast information of the location of the solar power generation equipment in the next daytime control period;

[0171] Determining a target power storage capacity according to the predicted light level;

[0172] During the current control period, the external power grid is controlled to charge the energy storage device with the target storage capacity as a charging target.

[0173] Further optionally, determining a target power storage amount according to the predicted light level includes:

[0174] If the predicted light level is a high level, the current storage capacity of the energy storage device is used as the target storage capacity;

[0175] If the predicted light level is a medium level, the predicted light power generation of the solar power generation equipment in the next daytime control period is determined, and the difference between the upper limit of the storage capacity of the energy storage device and the predicted light power generation is used as the target storage capacity;

[0176] If the predicted light level is a low level, the upper limit of the power storage amount is used as the target power storage amount.

[0177] Optionally, the predicted solar power generation amount of the solar power generation equipment in the next control period is determined by:

[0178] If the weather forecast information corresponding to the next control period at the location of the solar power generation equipment predicts precipitation, determining the predicted solar power generation amount as a preset value;

[0179] If the weather forecast information predicts that there is no precipitation, the predicted solar power generation is determined according to the predicted cloud cover of the weather forecast information; wherein the predicted solar power generation is linearly negatively correlated with the predicted cloud cover.

[0180] Optionally, the device further includes: an external electric energy load power supply scheduling module (not shown in the figure), which is used to control the external power grid to supply power to the load device when the sum of the energy storage power supply power of the energy storage device to the load device and the current solar power generation power is less than the current power consumption. Among them, the current external power supply power supplied by the external power grid to the load device satisfies: the sum of the current solar power generation power, the energy storage power supply power, and the current external power supply power is equal to the current power consumption.

[0181] It should be understood that the power supply scheduling device provided in the embodiment of the present invention can be implemented in other ways.
