[0002] It has become a global consensus to vigorously develop renewable energy, effectively respond to climate change, and promote clean and low-carbon energy transformation. In this context, the application of photovoltaic systems is considered to have great potential, and its efficiency in light capture even exceeds that of photosynthesis. Installing photovoltaic systems in open areas can minimize costs, which has also led to some photovoltaic power stations being built on agricultural land, thus triggering the "land competition" contradiction between energy production and food production. Therefore, the development of agricultural-photovoltaic complementarity has become a solution. Agricultural-photovoltaic complementarity is also known as agricultural-photovoltaic integration. It refers to both photovoltaic power generation and agricultural production on the same piece of land, achieving dual use of one land, and emphasizing the mutual influence, competitive relationship and coupled symbiosis between photovoltaic power generation and agricultural production. However, due to various restrictions such as wall-mounted electricity sales, agricultural production and station operation and maintenance in agricultural-photovoltaic complementary stations consume a large amount of conventional electricity, which will generate a large amount of carbon emissions.

[0036] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0038] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] As shown in FIG. 2 , in one embodiment, the energy supply method of the agricultural photovoltaic complementary power station of the present invention includes steps S11 to S12 .

[0040] Step S11: convert solar energy and wind energy into electrical energy based on photovoltaic equipment and wind turbine equipment, and configure the electrical energy to the energy storage end and the power consumption end through a unidirectional converter and a bidirectional inverter.

[0041] Specifically, the steps of converting solar energy and wind energy into electrical energy based on photovoltaic equipment and wind turbine equipment, and configuring the electrical energy to the energy storage end and the power consumption end through a unidirectional converter and a bidirectional inverter include:

[0042] The DC power generated by the photovoltaic device is preferentially stored in the energy storage end through the unidirectional converter;

[0043] The AC power generated by the wind turbine equipment is transmitted to the power consumption end through a bidirectional inverter.

[0044] Among them, the power-consuming end includes building-end equipment, agricultural-end equipment and transportation-end equipment. Building-end equipment includes air conditioners, computers, lamps and other electrical appliances inside the building, which are powered by the system. Agricultural-end equipment includes agricultural facilities such as field cold storage, irrigation systems, and smart greenhouses, which are powered by the system. Transportation-end equipment includes official vehicles, operation and maintenance vehicles, street lights and other transportation facilities, which are powered by the system. Each user end is equipped with transmission equipment and monitoring detectors. Photovoltaic equipment is installed on the tops of various buildings (comprehensive operation and maintenance buildings, booster stations, etc.), on both sides of roads with outstanding lighting conditions, and on the top of integrated light storage and charging sheds. Wind turbine equipment (small wind turbines) are installed on various open spaces such as the tops of buildings and roads.

[0045] The energy storage end includes fixed energy storage equipment, mobile energy storage equipment, distribution boxes, transmission equipment, and monitoring detectors; wherein the fixed energy storage equipment is used to store electric energy for a long time, and the mobile energy storage equipment is used to adjust the energy storage position and capacity according to the actual needs of the power consumption end. Among them, the mobile energy storage equipment can be used for electric agricultural machinery and electric irrigation facilities and other electric agricultural machinery and equipment.

[0046] During the day or when there is sunshine, solar energy is absorbed by photovoltaic panels and converted into DC power using the photovoltaic effect. The electricity generated by photovoltaics is directed to energy storage facilities for storage through a one-way exchanger. At this time, the one-way exchanger ensures that the electricity does not flow back to the photovoltaic panels. Electrochemical energy storage devices (such as batteries) store excess electricity during peak power generation (daytime or when the wind is strong). When there is wind, the blades of the wind turbine are blown by the wind, driving the internal rotor to rotate. Through the principle of electromagnetic induction, the rotor rotates to generate electricity, that is, the kinetic energy of the wind is converted into electricity. Both photovoltaic generators and wind turbine generators are connected to the one-way exchanger DC line. This means that the flow of electricity from the generator to the grid or energy storage facility is one-way and cannot flow in the opposite direction. The electricity generated by the wind turbine can be directly output to users for use, because wind power generation is usually synchronized with the grid and can directly meet the power demand. Due to the large fluctuations in the output of photovoltaic power generation, or for use during peak power demand. The electricity generated by photovoltaic power generation is preferentially stored in energy storage facilities. Electrochemical energy storage devices, such as batteries, can store excess electricity during peak power generation periods (such as during the day when there is plenty of solar energy or strong winds). In this way, when power generation is insufficient (such as at night or when the wind is weak), the energy storage device can release the stored energy to meet power demand.

[0047] This system design improves energy efficiency because it can store electricity during peak power generation and release it during peak demand, thereby balancing supply and demand. Through energy storage equipment, the system can provide more stable power output and reduce dependence on traditional energy generation. The system helps improve the reliability and flexibility of the power grid while reducing energy waste.

[0048] Step S12: acquiring power information of the power generation end, power consumption information of the power consumption end, energy storage end information and external power grid information, and allocating the power based on the smart energy management and control platform.

[0049] Specifically, the smart energy management and control platform obtains information from each system through sensors, including the power generation end, the power consumption end, and the energy storage end. It monitors the operating status and data of each end in real time to ensure accurate data transmission and processing. Based on real-time data, the smart platform calculates and predicts changes in power load and automatically allocates green power. Based on the actual input and output power, the smart platform controls the charging and discharging mode of the energy storage end and optimizes power distribution.

[0050] When the internal power generation scale is greater than the power demand, the excess electricity is connected to the grid through the bidirectional inverter; when the internal power generation scale is less than the power demand, additional electricity is obtained from the external power grid.

[0051] Based on the grid information, the smart energy management platform reduces the output of internal power generation equipment during peak power consumption periods to avoid grid overload, and increases power generation during off-peak power consumption periods to make full use of off-peak electricity.

[0052] Intelligent management effectively increases the service life of fixed and mobile energy storage units in the energy storage system, and improves the economic safety and stability of the entire agricultural photovoltaic complementary station energy supply system and the utilization rate of electric energy. The smart platform digitally displays the data of each terminal through monitoring equipment, making it easier for operators to grasp the status of each terminal in real time. It also provides remote control functions, allowing operators to manage and adjust the system through display screens or remote terminals.

[0053] The above-mentioned overall configuration is layered and optimized. The upper layer comprehensively considers economic and zero-carbon indicators to determine the optimal structure of the system and the optimal capacity of each device. The lower layer combines the output of renewable energy and the load requirements of users in the agriculture, construction, and transportation systems to optimize the optimal coordinated output of each device in the system, thereby ensuring the zero-carbon, economic, safe, and stable operation of the system.

[0054] An embodiment of the present invention also provides an agricultural-photovoltaic complementary power station energy supply system, which can implement the agricultural-photovoltaic complementary power station energy supply method described in the present invention, but the implementation device of the agricultural-photovoltaic complementary power station energy supply system described in the present invention includes but is not limited to the structure of the agricultural-photovoltaic complementary power station energy supply system listed in this embodiment. All structural deformations and replacements of the prior art made according to the principles of the present invention are included in the protection scope of the present invention.

[0055] like Figure 2a to Figure 2b As shown, in one embodiment, the energy supply system of the agricultural-photovoltaic complementary power station includes a power generation module 21, an energy storage module 22, a power consumption module 23 and a dispatching module 24. The power generation module includes a photovoltaic system, a wind turbine system, a single-phase switch, a bidirectional inverter, a first transmission device, a first monitoring detector, etc. The energy storage module includes a distribution box, a fixed energy storage device, a movable energy storage device, a second transmission device, and a second monitoring detector. The power consumption module includes building-end equipment, agricultural-end equipment and transportation-end equipment, which are used to use the electric energy based on actual needs; the dispatching module is used to obtain power information of the power generation end, power consumption information of the power consumption end, energy storage end information and external power grid information, and dispatch the electric energy based on the smart energy management and control platform.

[0056] Photovoltaic equipment and wind turbine equipment are the core power generation components in this application, which are responsible for converting solar energy and wind energy into electrical energy respectively. These two devices are connected to the rest of the system through unidirectional switches and bidirectional inverters to ensure that electrical energy can be effectively transmitted and distributed. The unidirectional switch is mainly used to convert the DC power generated by the photovoltaic equipment into AC power, and transmit it to the energy storage end or the power consumption end through the bidirectional inverter. The bidirectional inverter can realize the conversion of voltage and frequency during the power transmission process to meet the needs of different equipment.

[0057] The distribution box of the energy storage module is connected to the power generation module, power consumption module and the bidirectional inverter of the integrated photovoltaic storage and charging power station through DC lines, and is connected to the external power grid through AC lines.

[0058] Air conditioners, computers and other electrical appliances as well as lighting equipment inside the complex building are all connected to the smart energy management and control platform, giving priority to the use of green electricity generated by photovoltaics and wind turbines. The shortfall is supplemented by the energy storage system to ensure the stable power supply of the building system. Agricultural cold storage, irrigation systems, green agricultural machinery and other equipment required for agricultural production are all connected to the smart energy management and control platform. Green electricity is given priority, and mobile energy storage units are used to power electric agricultural machinery and electric irrigation facilities. Official vehicles, operation and maintenance vehicles, agricultural machinery charging, street lights and other equipment inside the station are all connected to the smart energy management and control platform. Green electricity is given priority, and mobile energy storage units are used to power electric agricultural machinery and electric irrigation facilities.

[0059] The smart energy management and control platform is a key component of this application, including smart power consumption intelligent terminals, transmission equipment, monitoring detectors, and display screens. It intelligently allocates power by obtaining power information from the power generation end, power consumption information from the power consumption end, energy storage end information, and external power grid information. The platform is closely connected with photovoltaic equipment, wind turbine equipment, unidirectional switches, bidirectional inverters, energy storage end, and power consumption end to ensure the coordinated operation of the entire system.

[0060] The various systems in the present invention are closely connected through unidirectional switches, bidirectional inverters, energy storage systems and smart energy management and control platforms to form a complete zero-carbon smart energy supply system. This system can not only efficiently utilize renewable energy, but also interact with the external power grid through intelligent management, ensuring the economy, safety and stability of the system.

[0061] In one embodiment, in the power generation system of the power supply system of the agricultural-photovoltaic complementary station of the present invention: the photovoltaic equipment and the wind turbine equipment generate electric energy through the photovoltaic system and the wind turbine system respectively. The unidirectional converter connects the DC lines of the photovoltaic generator and the wind turbine generator to ensure the unidirectional flow of electric energy. The bidirectional inverter is used to convert DC power into AC power, and to convert AC power into DC power, so as to realize interaction with the external power grid. The transmission equipment is responsible for transmitting electric energy from the power generation end to the power consumption end or the energy storage system. The monitoring detector is used to monitor the operating status of the power generation system. In the energy storage system of the power supply system of the agricultural-photovoltaic complementary station of the present invention: the distribution box serves as the central control unit of the energy storage system, connecting all energy storage units and the power consumption end. The fixed energy storage unit and the movable energy storage unit are used to store electric energy, and are connected to the distribution box through the transmission equipment. The monitoring detector monitors the status of the energy storage system. In the power consumption end system of the power supply system of the agricultural-photovoltaic complementary station of the present invention: the building system, the agricultural system, and the transportation system are the power consumption ends, which are connected to the distribution box through the transmission equipment to receive the power supply. There is also a monitoring detector inside each system to monitor the power consumption. The intelligent management system of the power supply system of the agricultural photovoltaic complementary station of the present invention includes: intelligent power consumption intelligent terminal, transmission equipment, monitoring detector and display screen. The operation data of the whole system is collected through sensors, and management and control are performed.

[0062] Power generation: During the day, photovoltaic equipment generates direct current, which is first stored in the energy storage system through a one-way exchanger. When there is wind, the wind turbine equipment generates alternating current, which is directly supplied to users through transmission equipment.

[0063] Energy storage management: The smart energy management system monitors power generation and stores excess power in fixed and mobile energy storage units. When power generation is insufficient, the stored power is released to meet demand.

[0064] Power distribution: The smart energy management system automatically allocates power according to power demand, giving priority to the use of energy storage systems for power supply, and supplementing from the external power grid when it is insufficient. The bidirectional inverter realizes the conversion between direct current and alternating current, as well as the interaction with the external power grid.

[0065] Power supply at the power consumption end: Building systems, agricultural systems, and transportation systems obtain electrical energy from the distribution box as needed.

[0066] System monitoring and optimization: Monitoring detectors collect system data in real time, and the smart energy management system analyzes and processes it. Based on the data analysis results, the system automatically adjusts the power generation, energy storage, and power supply strategies to optimize system operation.

[0067] Grid interaction: The smart energy management system coordinates and controls the energy flow with the external grid through a bidirectional inverter based on grid information and peak and valley periods. When there is excess power generation, the power is connected to the grid; when there is insufficient power generation, power is purchased from the grid.

[0068] Through the above connection relationships and work processes, the zero-carbon intelligent energy supply system for the agricultural-photovoltaic complementary station of this application can achieve efficient, stable and green power supply, while optimizing energy utilization, reducing operating costs and achieving zero carbon emissions.

[0069] The present invention forms a collaborative energy supply system by integrating photovoltaic power generation, wind power generation, energy storage system and smart energy management and control platform. This integration ensures the efficient and stable operation of the system under various energy input and output conditions. Through advanced algorithms and data analysis, the smart energy management and control platform not only monitors the operating status of the system in real time, but also predicts and optimizes power supply. This intelligent management helps to improve the response speed and decision-making efficiency of the system. The system design takes into account future expansion needs, such as the use of mobile energy storage devices, so that the system can flexibly adjust the energy storage capacity and location according to changes in electricity demand. The present invention emphasizes the use of renewable energy, helps to reduce dependence on fossil fuels, reduce greenhouse gas emissions, and meet the requirements of sustainable development. Through smart energy management, the system can store electricity during periods of low electricity prices and use or sell electricity during peak electricity price periods, thereby bringing economic benefits to users. In addition, the use of bidirectional inverters enables the system to flexibly control the inflow and outflow of electricity according to the grid conditions and internal needs, optimizing the utilization efficiency of energy.

[0070] like Figure 3 As shown, Figure 3 The installation scene diagram of the energy supply method of the agricultural photovoltaic complementary power station of the present invention in one embodiment is shown. In one embodiment, a certain agricultural science and technology park covers a large area and has multiple agricultural greenhouses, office buildings, experimental facilities and agricultural machinery and equipment. The park hopes to achieve self-sufficiency in green energy, reduce operating costs, and promote sustainable development by implementing the energy supply system of the agricultural photovoltaic complementary power station.

[0071] Step S31: Generation and configuration of electrical energy

[0072] In the park, photovoltaic equipment is installed on the top of agricultural greenhouses, office building roofs and parking sheds, using the photovoltaic effect to convert solar energy into direct current electricity. Small wind turbine equipment is installed in open areas of the park, using the kinetic energy of wind to generate alternating current electricity through the principle of electromagnetic induction.

[0073] Through the unidirectional converter, the DC power generated by photovoltaics is first stored in the energy storage end to ensure that the power does not flow back to the photovoltaic panels. The AC power generated by the wind turbine is directly transmitted to the power consumption end of the park through the bidirectional inverter to power the facilities in the park.

[0074] Step S32: Power allocation of the smart energy management and control platform

[0075] The smart energy management and control platform obtains real-time information on power generation, power consumption, energy storage and external power grid through sensors installed in various locations.

[0076] During the day when the sun is bright or the wind is blowing, the platform automatically allocates electricity according to the power generation and stores the excess electricity in fixed and mobile energy storage devices. At night or when the wind speed is low, the platform releases the electricity in the energy storage device to meet the power demand in the park. Based on the grid information, the platform reduces the external grid power supply during peak electricity price periods to reduce operating costs; during low electricity price periods, the platform purchases electricity from the external grid to supplement the energy storage.

[0077] Among them, the park has installed several fixed energy storage systems, including lithium-ion battery packs and lead-acid battery packs, which are placed in special energy storage rooms to provide long-term and stable energy storage. In order to improve the flexibility and emergency response capabilities of energy storage, the park is also equipped with several mobile energy storage units, such as battery energy storage vehicles, which can be quickly deployed within the park to respond to sudden power demands. During peak power generation, fixed energy storage devices and mobile energy storage devices automatically receive excess power from photovoltaic devices and wind turbines and store it. During low power generation or when the power demand in the park increases, the energy storage system will release the stored power according to the instructions of the smart energy management and control platform to ensure the continuity and stability of the power supply in the park. The bidirectional inverter enables the energy storage system to interact with the external power grid. When the external power grid electricity price is low, the energy storage system can purchase electricity from the power grid for charging; when the electricity price is high, the energy storage system can discharge to the grid to achieve efficient use of electricity and maximize economic benefits. When power generation equipment cannot operate normally due to power grid failure or extreme weather, the energy storage system can serve as an emergency power source to provide necessary power support for key facilities in the park (such as laboratories, cold storage facilities, etc.).

[0078] The park has significantly reduced the consumption of traditional energy and achieved efficient use of green energy through the energy supply system of the agricultural photovoltaic complementary power station. Through the optimization and allocation of the smart energy management and control platform, the park has reduced external power purchases during peak electricity price periods, effectively reducing electricity bills. The application of the energy storage system ensures that the park can maintain a stable power supply when power generation is insufficient, improving the operational reliability of the park. The implementation of the system has reduced greenhouse gas emissions, contributed to environmental protection, and is in line with the park's sustainable development concept.

[0079] In one embodiment, the load required by each agricultural-photovoltaic complementary station is different. Taking an agricultural-photovoltaic complementary station in Guangdong as an example, through calculation, the electricity consumption of the agricultural system is about 1.0687 million kWh / year, the electricity consumption of the building system is about 401,200 kWh / year, and the electricity consumption of the transportation system is about 18,600 kWh / year. The total electricity consumption is about 1.4885 million kWh / year. Based on this, the power generation is determined and the required installed capacity is calculated. By considering the internal space layout of the station, the wind turbines and photovoltaic facilities are arranged reasonably. The following is the power consumption of each system in an agricultural-photovoltaic complementary station in Guangdong:

[0080] Table 1 Power consumption of each system in a photovoltaic complementary station in Guangdong

[0081]

[0082] Based on this, the total annual electricity consumption of a certain agricultural photovoltaic complementary station in Guangdong is 1.4885 million kWh. This data is the basis for determining the power generation and installed capacity. In order to meet the annual power demand of the station, the power generation system needs to generate at least 1.4885 million kWh of electricity. Taking into account the efficiency of photovoltaic power generation systems and wind power generation systems and local climatic conditions, the actual power generation needs to be slightly higher than this value to compensate for system losses and weather effects. Installed capacity refers to the maximum output power of the power generation system, which is calculated based on the efficiency and time of the system. After determining the power generation and required installed capacity, the wind turbines and photovoltaic facilities are reasonably arranged. For agricultural systems, the power consumption is the largest, mainly concentrated in cold storage, irrigation facilities and greenhouse systems, which have high requirements for the stability and reliability of power supply. For building systems, power consumption is mainly concentrated in comprehensive buildings and booster stations, among which electrical appliances and air conditioners are the main power-consuming equipment. For transportation systems, power consumption is relatively small, mainly vehicle charging piles. By analyzing the electricity consumption of each system, the power generation system of the agricultural-photovoltaic complementary station can be rationally planned to ensure that it can meet the power needs of the station, while optimizing the energy structure and improving energy utilization efficiency.
