考虑能量梯级利用的工厂综合能源系统多能协同优化
|
摘要
工业园区是典型的复杂能源系统,通过利用多能源之间的耦合机制,实现多能互补,可显著提升其经济效益与能源利用率。为此,文中针对工业园区提出了一种考虑能量梯级利用的工厂综合能源系统多能协同优化模型。首先,介绍工厂综合能源系统架构,再对综合能源系统中的能量生产设备、能量转换设备以及能量存储设备进行独立建模。基于此,以日运行费用最低为优化目标,在冷热电功率平衡约束以及设备物理约束下,采用混合整数线性规划法对模型进行求解。所提模型遵循"品位对口,梯级利用"的科学用能思想,按热品位高低进行能量梯级利用,实现工业生产流程与设备运行参数的综合优化。算例分析表明,所提的优化调度策略更契合工程的实际需求,可降低工业用户的运行费用。
The industrial park is a typical complex energy system.Multi-energy complementation can be achieved by making use of the coupling mechanism of multiple energy sources,which can significantly enhance the economic efficiency and energy utilization of plant.Thus,this paper proposes a multi-energy cooperative optimization model of integrated energy system in the plant considering stepped utilization of energy.Firstly,the structure of the integrated energy system in a plant is described.Then,the energy production equipment,energy conversion devices,and energy storage devices in the integrated energy system are independently modeled.Taking the lowest daily operation cost as the optimization objective,the mixed integer linear programming method is used to solve the model under the constraints of cooling and thermal power balance and the physical constraints of equipment.The proposed model follows the idea of scientific energy use of "grade counterparts,stepped utilization",which achieves the stepped utilization of energy according to the grade of heat.Thus the optimization of industrial production process and equipment operating parameters is realized.Finally,the example analysis shows that the proposed optimal dispatch strategy is more suitable for the actual demand of engineering,and can reduce the operation costs of industrial users.
