基于安全性及“双碳”目标的设施农业供电系统优化

Optimization of Facility Agricultural Power Supply System Based on Safety and"Double Carbon"Goals

以广泛存在于新型农业中的可时移农业负荷为研究对象,提出了基于安全性及“双碳”目标的设施农业交直流混合供电系统优化模型并通过遗传算法求解得到最优方案。该模型以可时移负荷投切状态、储能SOC值以及电网购售电功率为控制变量,得到初始成本、供电成本、节能减排成本最低的各负荷工作电压等级以及负荷与储能电网协同工作模式,通过合理安排可时移负荷工作时间以及储能出力满足对上级电网削峰填谷、减小负荷季节性扰动以及降低损耗节约成本的要求,在避免了天气因素的影响、保障系统运行安全的同时,助力设施农业“双碳”目标的实现。

Taking the time-movable agricultural load widely existing in the new agriculture as the research object,the optimization model of facility agricultural AC-DC hybrid power supply system based on the goal of safety and"double carbon"is proposed and the optimal solution is obtained from genetic algorithm.The model takes the time-shift load cut state,the SOC value of energy storage and the power purchased and sold from the power grid as control variables to obtain the initial cost,power supply cost,the lowest energy conservation and emission reduction cost of each load working voltage level and the collaborative working mode of the load and energy storage grid.By reasonably arranging the time-shiftable load working time and energy storage output to meet the requirements of cutting peaks and filling,reducing the seasonal disturbance of load,and reducing losses and saving costs of the superior power grid,it helps to achieve the"double carbon"goals of facility agriculture while avoiding the impacts of weather factors and ensuring the safety of system operation.
