[0056] Embodiment 1
[0057] like Figure 1 As shown, in this embodiment, a wind-solar coordinated on-site comprehensive energy complementary system for use in facility agriculture industrial parks is provided, including: an electric energy module, a thermal energy module, and a wind-solar complementary water-lifting irrigation module.
[0058] The electric energy module is used to supply electric energy to the facility agriculture industrial park;
[0059] The thermal energy module is used to input the electric energy generated by the electric energy module into an electric heating device or an air source heat pump to obtain thermal energy;
[0060] The wind-solar complementary water-lifting irrigation module is used to use the aeration equipment to inhale air before the irrigation water enters the irrigation capillary tube and the dripper through the aeration component, so that a water-gas mixture is formed in the irrigation water and transported to the root zone of the crop, and water is lifted and irrigated based on wind and solar power generation.
[0061] The power module is the main source of energy supply in the facility agriculture industrial park. The system diagram is as follows: Figure 2 shown.
[0062] a. Wind energy: Wind power generation equipment converts wind energy into electrical energy to meet the power needs of the park. Wind resources are volatile, so they need to be used in combination with other energy resources.
[0063] b. Solar energy: Solar radiation is converted into electrical energy through photovoltaic power generation. This renewable energy source is characterized by diurnal and seasonal fluctuations, especially when the sun is abundant.
[0064] c. Biomass energy: Agricultural waste or organic waste in the park can be converted into biomass energy after waste collection and treatment, and supplied to the park as heat or electricity. The use of biomass energy can reduce waste in the park and realize the recycling of energy.
[0065] d. Conventional electricity: If the renewable energy supply is insufficient and there is volatility, the park can obtain supplementary electricity from the power grid. Grid power is usually used as a supplementary energy source to ensure stable power supply when renewable energy generation is insufficient.
[0066] e.Battery pack:
[0067] Stores electrical energy and can supply power to the load at any time. It stores energy when wind and solar power generation is sufficient and the load cannot be absorbed, and stores energy when electricity prices are low; it supplies energy when wind and solar power output is less than the load demand or when electricity prices are peak.
[0068] One end of the photovoltaic and wind power equipment is connected to a battery pack, and the equipment that generates electricity from biomass energy is connected to the battery pack. One end of the battery pack is connected to the electricity demand equipment of the facility agriculture system. The photovoltaic and wind power equipment transmits the converted electricity to the power-consuming equipment of the facility agriculture system through the battery pack, stores part of the electricity and transmits part of the excess electricity to the national power grid.
[0069] The electric energy output by the power module provides energy for the agricultural industrial park, reducing dependence on external energy. In the case of insufficient electricity, the power grid can supplement electricity to ensure stable power supply.
[0070] The demand for heat in the facility agriculture industrial park is relatively large. The use of heat energy in the comprehensive energy system of the facility agriculture industrial park mainly relies on the synergy of multiple energy forms. The electric energy generated by the electric energy module is input into the electric heating equipment and air source heat pump to obtain heat energy. Figure 3 shown.
[0071] a. Electric heating equipment:
[0072] Convert electrical energy into thermal energy to release heat directly or circulate heat medium in heating pipes to meet heating needs.
[0073] b. Air source heat pump:
[0074] Air source heat pumps do not cause any pollution to the air when working, and have high conversion efficiency and low loss. They can be used as a heat source for environmental heating in facility agricultural parks.
[0075] c. Boiler:
[0076] One end of the biogas fermentation tank is connected to a biogas boiler and a micro gas turbine. The fuel generated by the biogas fermentation tank drives the biogas boiler and the micro gas turbine to operate. The micro gas turbine is connected to the waste heat boiler to generate heat energy through the waste heat boiler. Since the gas production efficiency of biogas fermentation is related to temperature, the ambient temperature alone cannot meet the gas production requirements, so the heat required for biogas fermentation needs to be supplemented by other heat sources. In addition to supplying biogas fermentation with heat energy, the excess heat generated by the biogas boiler and the waste heat boiler is transported to the heat storage device to store excess heat and provide supplementary heat energy for the agricultural industrial park during peak demand periods or when energy production is insufficient.
[0077] In addition, one end of the power module is connected to an electric heating device and an air source heat pump. Part of the heat generated by the equipment is used to meet the heating needs of the facility agriculture park, and the other part is supplied to the biogas fermentation tank. These heating methods, combined with energy storage systems, photovoltaic power generation and wind power generation, can ensure the stability of the internal environment of the park with low carbon emissions.

Before the irrigation water enters the irrigation capillary tube and the dripper, the air is sucked in by the aeration equipment, and a water-gas mixture is formed in the irrigation water and transported to the root zone of the crop, thereby facilitating the soil and crops to absorb fertilizer and water. At the same time, the system makes full use of wind power and solar power generation for water lifting irrigation, realizes the integration of wind power generation and solar power generation, and solves the problems of low automation level, waste of water resources and poor water and fertilizer absorption effect of crops during irrigation in the existing irrigation system.

The gas energy generated by the biogas fermentation tank can drive the operation of the biogas boiler and the micro gas turbine. The micro gas turbine is connected to a waste heat boiler to generate heat energy through the waste heat boiler. The heat energy generated by the biogas boiler and the waste heat boiler is supplied to biogas fermentation, and the excess part is transported to the heat storage device to store excess heat and provide supplementary heat energy for the facility agriculture industrial park during peak demand periods or insufficient energy production.
[0086] Raw materials for fertilizer production;
[0087] The biogas slurry and biogas residue produced by the biogas fermentation tank can be processed and applied to farmland as organic fertilizer to meet the nutritional needs of crops. One end of the biogas fermentation tank is connected to the fertilizer tank, which provides fertilizer raw materials for the fertilizer tank, and one end of the water reservoir is connected to the fertilizer tank, which provides fertilizer water for the fertilizer tank. The organic fertilizer produced by the fertilizer tank can be used in agricultural production in the facility agriculture industrial park to maximize the use of renewable energy, reduce energy costs, and promote the green and sustainable development of the park.

[0115] The technical effects of this embodiment are:
[0116] Wind and solar energy are intermittent and unstable renewable energy sources. The facility agriculture industrial park can ensure the stability of energy supply by using a comprehensive energy complementary system (such as wind and solar complementarity, energy storage system and intelligent scheduling, etc.). By combining wind and solar energy with energy storage equipment (such as battery energy storage), the system can provide continuous power when wind and solar resources are insufficient, ensuring the normal operation of the park facilities.
[0117] Facility agriculture usually requires a lot of energy support (such as lighting, temperature control, irrigation, etc.).
