可再生能源为主体的农业能源互联网碳循环建模与优化

“双碳”目标对能源领域和农业领域的节能减排提出了更高要求。农业能源互联网作为能源与农业深度耦合的产物,是实现碳中和的重要手段。提出一种面向农业能源互联网碳循环的核算方法以及计及农业柔性负荷及碳交易的农业能源互联网优化运行策略。首先,构建了农业园区内光伏、热电联产等碳排放核算模型。其次,以园区日运行成本最低为目标函数,考虑等式及不等式约束,构建优化调度模型。最后,以某园区农业能源互联网为研究对象对优化模型进行仿真,详细核算园区内碳排放情况,并通过与其他农业园区对比验证碳模型的正确性。结果表明,该优化调度策略可有效降低农业园区碳排放,实现碳中和。

In the context of the “double carbon” goal, higher requirements have been put forward for energy conservation and emission reduction in the energy and agricultural fields. As a product of the deep coupling of energy and agriculture, the Agricultural Energy Internet is an important means to achieve “carbon neutrality”. This paper proposes an accounting method for the carbon cycle of the Agricultural Energy Internet and an optimal operation strategy for the Agricultural Energy Internet that takes into account agricultural flexible loads and carbon trading. Firstly, this paper constructs an accounting model for carbon emissions of photovoltaic generation and cogeneration in agricultural parks. Secondly, taking the lowest daily operating cost of the park as the objective function, considering the constraints of equality and inequality, an optimal scheduling model is constructed. Finally, the optimization model is simulated by taking the agricultural energy internet of a certain park as the research object, the carbon emissions in the park are calculated in detail, and the correctness of the carbon model is verified by comparing with other agricultural parks. The results show that the optimal scheduling strategy can effectively reduce the carbon emissions of agricultural parks and achieve “carbon neutrality”.
