Development and application of smart energy edge control device for facility agricultural industrial parks

针对目前乡村存在供电设施季节性过载问题突出、能源综合利用经济性差、光伏消纳能力弱和落地难等问题,研究设计了一种智慧用能边缘控制装置,构建云边协同系统控制架构,基于组态监控软件实现设施农业产业园中设施农业负荷的智能化控制,提高可再生能源利用率,提高经济效益。以某日光温室为研究对象,以CY-LFC121C设备为边缘控制核心进行了边缘控制装置的搭建,以日光温室日运行费用、光伏消纳率及CO_(2)减排率为指标,利用改进的蝗虫优化算法进行多目标寻优及实验室仿真试验,并于甘肃省某日光温室进行现场验证。结果表明,该装置可有效应对现代设施农业负荷综合能源利用率低、经济性差、落地难等问题,为边缘控制装置的优化设计提供参考。

Aiming at problems of seasonal overloading of power supply facilities,poor economy of comprehensive utilization of energy,weak capacity of photovoltaic energy consumption,and difficulty of landing in countryside,a smart energy edge control device was de-signed,cloud edge collaborative system control architecture was constructed,and intelligent control of facility agricultural loads in facil-ity agricultural industrial park was realized based on configuration monitoring software,improving utilization rate of renewable energy and economic benefits.Taking a solar greenhouse as research object,edge control device was built with CY-LFC121C equipment as edge control core,taking workshop daily operation cost,PV consumption rate and CO_(2) emission reduction rate as indexes,using im-proved locust optimization algorithm for multi-objective optimization,laboratory simulation experiments and on-site verification in a sol-ar greenhouse in Gansu Province were conducted.Results showed that,the device could effectively deal with problems of low compre-hensive energy utilization,poor economy and difficult landing of modern facility agriculture loads,and results of this study could provide a reference for optimal design of edge control devices.
