Abstract
Description
Technical Field
[0001] This invention belongs to the field of power distribution network energy dispatching technology, and particularly relates to a method and system for regulating energy consumption in glass greenhouses based on the characteristics of tomatoes. Background Technology
[0002] Venlo-type glass greenhouses, as representative production devices of modern agricultural facilities, are widely used in the cultivation of many agricultural products, one of the most important applications being the cultivation of tomatoes.
[0003] These types of glass greenhouses typically purchase electricity in a lump sum according to pre-set energy demand. However, this procurement model usually leaves a large surplus, resulting in underutilization of the electricity and leading to high operating costs and substantial losses for these greenhouses. Therefore, integrating these glass greenhouses with the external public power grid's demand response system, and profiting from the surplus energy generated by the greenhouses through this system, is an effective way to reduce their energy costs.
[0004] However, tomato growth is a highly nonlinear, dynamic, and complex process, strongly coupled with greenhouse environmental factors such as light and temperature. Therefore, describing these complex environmental constraints and accurately translating them into quantifiable and executable key energy constraints for greenhouse production when participating in grid dispatch, while ensuring that such greenhouses do not compromise tomato yield when responding to grid commands, remains a challenge for existing technologies. Summary of the Invention
[0005] To address the aforementioned technical problems, this invention proposes a method and system for regulating energy consumption in glass greenhouses based on the characteristics of tomatoes.
[0006] The first aspect of this invention proposes an energy regulation method for glass greenhouses based on the characteristics of tomatoes, the method comprising: A growth model for tomato seedlings was established based on the relative thermal effect and total photosynthetically active radiation of the glass greenhouse. Establish the constraints for the tomato seedling growth model; Establish a heat load model for the glass greenhouse related to the relative thermal effect and a supplemental light load model for the glass greenhouse related to the total photosynthetically active radiation; The temperature control equipment load and the supplemental lighting load of the glass greenhouse are calculated using the heat load model and the supplemental lighting load model of the glass greenhouse, respectively. The energy consumption adjustment range of the glass greenhouse is obtained by considering the baseline load of the glass greenhouse, the load of the temperature control equipment of the glass greenhouse, and the supplemental lighting load of the glass greenhouse.
[0007] A second aspect of the present invention provides an energy regulation system for a glass greenhouse based on the characteristics of tomatoes, the system comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to implement the method as described in the first aspect of the present invention.
[0008] In summary, the energy regulation method and system for glass greenhouses based on the characteristics of tomatoes proposed in this invention comprehensively considers the growth factors affecting tomato seedlings and converts them into energy demands that meet these growth factors. By calculating the energy demand, the energy surplus of the glass greenhouse that can participate in regulation without affecting crop growth is obtained. This energy surplus can then be used to participate in grid dispatch to generate revenue, thereby achieving a better balance between economic benefits and crop yield. Attached Figure Description
