[0030] The realization of the object of the present invention, its functional characteristics and advantages will be further described in conjunction with the embodiments with reference to the drawings. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] Moreover, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] To achieve the above object, refer to Figure 1 The present invention provides a comprehensive control method for a photovoltaic tea garden, including the following steps:

[0034] S100: Determine the rainfall difference value at each stage of tea growth and the rainfall difference period corresponding to the rainfall difference value according to the historical rainfall data of the location where the photovoltaic tea garden is located and the water requirements at each stage of tea growth.

[0035] In this step, collect the historical rainfall data of the location where the photovoltaic tea garden is located, including information such as rainfall amount and rainfall time distribution over the years. According to each stage of tea growth (such as the budding stage, the vigorous growth stage, the mature stage, etc.), determine the water requirements of tea at each stage. Compare the water requirements at each stage with the historical rainfall data, and calculate the rainfall difference value at each stage of tea growth, that is, the difference between the water requirements and the actual rainfall amount. Determine the rainfall difference period corresponding to the rainfall difference value, that is, in which time periods the water requirements of tea are greater than the actual rainfall amount and additional irrigation water is needed.

[0036] S200: Based on the historical power generation amount and historical power sales amount of the photovoltaic tea garden during the rainfall difference period, calculate the water storage amount of the upper reservoir during the process of storing and discharging electricity by pumping and discharging water between the lower reservoir and the upper reservoir.

[0037] In this application, pumped storage is applied to photovoltaic power generation. Pumped storage is an energy storage technology that uses water as an energy storage medium and realizes the storage and management of electric energy through the mutual conversion of electric energy and the potential energy of water. It usually consists of two reservoirs with different altitudes (upper reservoir and lower reservoir), a water turbine, a water pump, and a supporting water conveyance system, etc.

[0038] During the low power load period, use the surplus electric energy in photovoltaic power generation to drive the water pump to pump water from the lower reservoir to the upper reservoir, and store the electric energy as the potential energy of water; during the high power load period, release the water in the upper reservoir to drive the water turbine to generate electricity, convert the potential energy of water into electric energy, and transmit it to the power grid.

[0039] In this step, it is necessary to determine the water storage volume of the upper reservoir during the rainfall difference period for subsequent regulation. In this way, the water storage situation of the photovoltaic power station can be accurately grasped, providing accurate data support for subsequent water resource allocation. It can also optimize power management. After knowing the water storage volume, the power generation and power sales strategies of the photovoltaic power station can be reasonably arranged to avoid power waste and improve the economic benefits of the photovoltaic power station. In this way, the operation of the power station is guaranteed, ensuring that during the rainfall difference period, the photovoltaic power station has sufficient water storage volume for pumped storage to ensure the stable operation of the power station.

[0040] S300: Determine the irrigation water consumption of the corresponding upper reservoir of the photovoltaic tea garden during the rainfall difference period according to the rainfall difference value. The irrigation water consumption is at least greater than the rainfall difference value.

[0041] The irrigation water consumption is greater than the rainfall difference value, that is, a certain irrigation safety margin is provided. The irrigation safety margin can be adjusted according to actual needs and the scale of the tea garden, generally 10%-20% of the rainfall difference value.

[0042] S400: Determine the power generation water storage volume according to the water storage volume of the upper reservoir and the irrigation water consumption during the rainfall difference period, and adjust the power sales volume.

[0043] Power generation water storage volume = upper reservoir water storage volume - irrigation water consumption. In this step, the power sales volume of the photovoltaic power station is mainly adjusted according to the power generation water storage volume. If the power generation water storage volume is sufficient, the power sales volume can be appropriately increased; if the power generation water storage volume is insufficient, the power sales volume needs to be reduced to give priority to ensuring the irrigation needs of the tea garden.

[0044] In the above comprehensive control method of the photovoltaic tea garden, the irrigation water consumption required for each stage of the tea is determined according to historical rainfall data and water demand. The water storage volume corresponding to the power generation of the photovoltaic tea garden and the irrigation water consumption are comprehensively considered. This method can not only accurately plan irrigation requirements to ensure the growth of tea, but also optimize power management to improve the economic benefits of the photovoltaic power station, with significant economic and social benefits.

[0045] In some embodiments, the operation of according to the historical rainfall data of the location of the photovoltaic tea garden and the water demand in each growth stage of the tea includes:

[0046] Determine the water demand of the germination period, growth period, picking period and dormancy period of the tea according to the tea variety, growth environment and historical growth data.

[0047] Determine the rainfall difference value of the germination period, growth period, picking period and dormancy period of the tea and the corresponding stage of the tea according to the historical rainfall data of the location of the photovoltaic tea garden during the germination period, growth period, picking period and dormancy period.

[0048] By subdividing the difference value between the water demand and rainfall during the tea growth stages, the tea garden irrigation can be managed more precisely. Targeted irrigation plans can be made according to the characteristics of different stages, further improving the suitability of tea growth and reducing the problem of unreasonable irrigation caused by unclear stages.

[0049] In some embodiments, the step of calculating the water storage volume of the upper reservoir during the process of storing and discharging electricity by pumping and releasing water between the lower reservoir and the upper reservoir based on the historical power generation amount and historical electricity sales amount of the photovoltaic tea garden includes:

[0050] Collect the historical power generation amount and historical electricity sales amount data of the photovoltaic tea garden during the rainfall difference period.

[0051] According to the power generation power and power generation time of the photovoltaic power station, calculate the total power generation amount of the photovoltaic power station during the rainfall difference period.

[0052] Combined with the historical electricity sales amount data, calculate the water storage volume of the upper reservoir during the process of storing and discharging electricity by pumping and releasing water during the rainfall difference period. In this embodiment, through detailed data collection and calculation, the change of the water storage volume of the upper reservoir can be grasped more accurately, providing a more reliable basis for subsequent power generation and irrigation water allocation, and improving the operation accuracy and reliability of the entire system.

[0053] In some embodiments, the total irrigation water volume is 1.1 to 1.2 times the rainfall difference value. By setting the total irrigation water volume slightly higher than the rainfall difference value in this embodiment, a certain redundancy is provided for the irrigation process, which can effectively cope with possible irrigation losses, rainfall errors, etc., ensuring that the tea garden can obtain sufficient water supply under any circumstances and further guaranteeing the growth of tea.

[0054] In some embodiments, the step of determining the power generation water storage volume based on the water storage volume of the upper reservoir and the total irrigation water volume during the rainfall difference period and adjusting the electricity sales amount includes:

[0055] According to the total irrigation water volume and the number of days in the rainfall difference period, determine the daily irrigation water volume during the rainfall difference period.

[0056] According to the daily water storage volume of the upper reservoir and the daily irrigation water volume during the rainfall difference period, determine the daily power generation water storage volume and electricity sales amount.

[0057] This method can still use the part of the total irrigation water volume except the daily irrigation water volume for power generation. Compared with storing all the total irrigation water volume in the upper reservoir during the entire rainfall difference period, the above method does not affect irrigation and maximizes power generation as much as possible.

[0058] In this embodiment, by refining the adjustment of water storage capacity and electricity sales volume to each day, the dynamic balance management of power generation and irrigation water use is achieved, enabling flexible adjustment according to the actual situation of each day, further optimizing power generation benefits and irrigation effects, and improving the overall operation efficiency of the system.

[0059] In some embodiments, it further includes:

[0060] During the rainfall difference period, real-time future rainfall prediction data and the electricity demand of the power grid are collected, and the daily power generation water storage capacity and electricity sales volume are dynamically adjusted.

[0061] For example, through the real-time rainfall prediction data provided by the meteorological department, the rainfall amount and rainfall time distribution in the next few days are obtained. On the one hand, rainfall can supplement the water demand of the tea leaves, thus reducing the demand for irrigation volume, and the water volume available for power generation in the upper reservoir increases. On the other hand, it can supplement the water demand of the upper reservoir, and the water volume available for power generation in the upper reservoir also increases.

[0062] The electricity demand can be obtained by cooperating with the power grid operator to obtain the electricity demand data of the power grid in real time, including peak and off-peak electricity consumption periods.

[0063] In this embodiment, by introducing real-time rainfall prediction and power grid demand data, the system can make an early response, adjust power generation and irrigation strategies according to future rainfall conditions, and optimize electricity sales volume in combination with power grid demand, further improving the flexibility and adaptability of the system and achieving the optimal allocation of resources.

[0064] In some embodiments, if the water storage capacity is sufficient and future rainfall prediction data predicts rainfall replenishment, the daily power generation water storage capacity and electricity sales volume are dynamically increased.

[0065] In this embodiment, the sufficient water storage capacity and the replenishment potential of future rainfall are fully utilized. By increasing the power generation water storage capacity and electricity sales volume, the power generation benefits are further improved, and at the same time, the idle waste of water resources is avoided, achieving the maximum utilization of resources.

[0066] In some embodiments, if the water storage capacity is insufficient and future rainfall prediction data predicts no rainfall replenishment, the daily power generation water storage capacity and electricity sales volume are dynamically reduced.

[0067] In this embodiment, the optimization and adjustment of power generation and power sales strategies under favorable conditions are further emphasized to achieve the efficient operation of the photovoltaic tea garden.

[0068] The present invention also provides a comprehensive control system for a photovoltaic tea garden, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the above-mentioned comprehensive control method for the photovoltaic tea garden are realized.

[0069] The present invention also provides a computer-readable storage medium storing a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned comprehensive control method for a photovoltaic tea garden are implemented.

[0070] In the above-mentioned comprehensive control method for a photovoltaic tea garden, the irrigation water consumption required for each stage of tea is determined according to historical rainfall data and water demand. The water storage capacity corresponding to the power generation of the photovoltaic tea garden and the irrigation water consumption are comprehensively considered. This method can not only accurately plan irrigation requirements to ensure the growth of tea, but also optimize power management to improve the economic benefits of the photovoltaic power station, and has significant economic and social benefits.
