摘要
双碳政策推动下,乡村农业综合能源系统(integrated energy system,IES)的多能耦合关系更加复杂。为实现农业园区可靠运行,提出面向生态农业IES的多能互补与低碳运行优化调度策略。首先,基于农业园区的能量流动关系,建立沼气生产环节、多能耦合供应环节以及柔性负荷需求响应环节的数学模型。其次,考虑光伏、负荷和沼气的不确定性,建立生态农业IES两阶段鲁棒优化模型。模型引入碳排放成本和启停成本,可降低农业生产碳排放,防止机组频繁启停。然后,采用列与约束生成算法(column-and-constraint generation,C&CG),结合强对偶定理与线性化理论实现模型求解。最后,基于江西省某生态牧场IES进行算例仿真,验证所提策略的有效性。仿真结果表明,所提策略可实现生态农业IES的协调运行,提高系统经济性、低碳性和能效性。
Driven by the carbon peak and carbon neutrality goals,the multi-energy coupling relationship of rural agriculture integrated energy system(IES)is more complex.In order to realize reliable operation of agricultural parks,a multi-energy complementary and low-carbon operation optimization scheduling strategy for eco-agriculture IES is proposed.First,considering the energy flow relationship in the agricultural park,the mathematical models of biogas production,multi-energy coupling supply and flexible load demand response are established.Second,considering the uncertainty of photovoltaic,load and biogas,a two-stage robust optimization model of eco-agriculture IES is established.The model introduces carbon emission cost and startup and shutdown cost,which can reduce agricultural carbon emissions and prevent frequent startup and shutdown of units.Then,column and constraint generation algorithm(C&CG)is used to solve the model,combining strong duality theorem and linearization theory.Finally,a numerical example based on IES of an ecological pasture in Jiangxi Province is used to verify the effectiveness of the proposed strategy.The simulation results show that the proposed strategy can realize the coordinated operation of eco-agricultural IES,and improve the system economy,low carbon and energy efficiency.
