【摘要】：综合能源系统(integrated energy system,IES)是实现多能耦合与能量梯度利用的关键技术。工厂是包含多种能源形式的复杂能源系统,存在较大的优化空间。文章针对工厂IES提出一种考虑冰蓄冷空调多种工作模式的多能协同优化模型。首先介绍工厂IES供能架构,并对IES中的各类设备进行建模。然后,以运行维护成本、购电成本、燃料成本和储能折旧成本构成的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。算例分析表明,多能协同优化策略能够有效减少工业用户的运行费用,设备的不同工作模式也将影响工厂的供能策略。优化模型可根据工厂设备工作模式不同,提供更加准确的优化策略,在工程实际中具有很好的参考价值。
[Abstract]:Integrated energy system is the key technology to realize multi-energy coupling and energy gradient utilization.Plant is a complex energy system with multiple energy forms, and there is a large space for optimization.In this paper, a multi-performance cooperative optimization model considering several working modes of ice storage air conditioning is proposed for factory IES.This paper first introduces the IES energy supply architecture of the factory, and models all kinds of equipments in IES.Then, the minimum daily operating cost, which consists of operation and maintenance cost, electricity purchase cost, fuel cost and depreciation cost of energy storage, is taken as the optimization objective, under the constraints of the balance of the cooling and heating power and the physical constraints of the equipment.The mixed integer linear programming method is used to solve the model.The example analysis shows that the multi-energy cooperative optimization strategy can effectively reduce the operating cost of industrial users, and the different working modes of the equipment will also affect the power supply strategy of the plant.The optimization model can provide more accurate optimization strategy according to the different working mode of plant equipment and has good reference value in engineering practice.
