计及风光就地消纳的设施农业产业园区综合能源系统多目标优化调度方法

针对设施农业产业园区在生产过程中能源得不到高效利用且能耗费用较高的问题,文章提出了一种计及风光就地消纳的设施农业产业园区综合能源系统(integrated energy system, IES)多目标优化调度方法。首先,建立了包含风-光-沼可再生能源的设施农业产业园区综合能源系统出力模型。然后,考虑多种约束条件,并以能耗费用最低与风光消纳率最大作为目标,利用基于反向学习的改进型多目标正余弦优化算法进行求解。最后,以某设施农业产业园区综合能源系统作为实际算例对所提方法进行了验证。结果表明,所提优化调度方法可有效降低园区日运行费用、提高风光就地消纳率。

A Multi-objective Optimal Scheduling Method for Integrated Energy System of Protected Agricultural Industrial Park Considering Local Consumption Rate of Wind and Solar Engery

In order to solve the problems of inefficient energy utilization and high energy cost in the production process of protected agricultural industrial park, a multi-objective optimization scheduling method for integrated energy system (IES) of protected agricultural industrial park is proposed, which takes into account the local consumption of wind and solar energy. Firstly, the output model of integrated energy system of protected agricultural industrial park including renewable energy such as wind, solar and biogas power is established. Then, considering various constraints, taking the minimum energy consumption and maximum consumption rate of wind and solar energy as the objectives, the improved multi-objective sine-cosine algorithm based on reverse learning is used to solve the problem. Finally, the integrated energy system of a protected agricultural industrial park is taken as an example. The results show that the optimal scheduling method can effectively reduce the daily operation cost of the park and improve the local consumption rate of wind and solar energy.
