Abstract
In vigorous development of modern greenhouse industry,multi-span greenhouses are equipped with a large number of devices and involve multiple systems and various types.However,traditional power supply methods have several drawbacks,includ-ing poor power supply stability,low energy utilization efficiency,high operating costs,and environmental pollution,which signific-antly hinder multi-span greenhouse industry further development.To effectively solve above problems,Beijing Academy of Agriculture and Forestry Sciences'multi-span greenhouse was selected as a typical case.Through in-depth on-site investigations,a smart power sup-ply system based on renewable energy was designed combined with actual power consumption needs of multi-span greenhouses and re-newable energy sources characteristics and advantages such as solar energy,wind energy,and others.Research results showed that this system could significantly reduce multi-span greenhouse operating costs,remarkably improve energy utilization efficiency and intelligent management level.It has important theoretical and practical significance for protected agriculture sustainable development and industry green transformation and upgrading promotion.关键词
