| 摘要: |
| 以具备良好可中断潜力的生产型用户为研究对象，提出考虑生产设备轮停和物料库存调节的需求响应优化决策方法。分析水泥生产全作业流程，按生产特性和物料储库配备情况划分可中断和不可中断生产环节及设备。考虑储库对相邻生产设备物料进出的解耦作用，以储库为节点，提出全作业物料流入-流出过程的建模方法。考虑可中断设备启停状态及储库进出料速度的轮流调节，刻画全作业物料进出动态平衡、储库库存及存储空间限制，确定全作业过程可控功率及调控边界。以生产设备用电成本、启停成本和作业速度调节成本最低为目标，满足库存与产量、设备运行约束，提出生产型用户日前需求响应优化决策模型，确定各时段生产设备启停状态及其作业速度。算例结果表明，采用所提方法响应分时、实时电价激励，能够在保证水泥日产量需求下有效实现负荷削峰填谷，避免生产设备频繁启停响应，降低总运行成本。 |

| Abstract: |
| Taking the production-oriented users with good interruptible potential as the research objects, an optimal decision method of demand response is proposed considering the rotating interrupt of production devices and material inventory regulation. The entire production process of cement is analyzed, and the interruptible and non-interruptible production processes and devices are classified according to the production characteristics and material storage facility condition. Considering the decoupling rule of reservoirs on the material flow between adjacent production devices, a modeling method of the material flow-in and flow-out process of entire production is proposed with the reservoirs as the nodes. Considering the start-stop state of interruptible devices and the in turn regulation of material flow in the reservoirs, the dynamic balance of entire production material flow and the limitation of reservoir inventory and storage space are described, and the controllable power and regulation boundary of entire production process are determined. A day-ahead demand response optimal decision model for production-oriented users is proposed to determine the start-stop state and production speed of production devices during each period, which takes the minimum electricity consumption cost, start-stop cost and production speed adjusting cost of production devices as the objects, and satisfies the constraints of inventory, production and device operation. The example results show that when adopting the proposed method to respond to the time-of-use or real-time pricing incentives, the load peak shaving and valley filling can be effectively realized while guaranteeing the daily cement production demand, frequent start-stop response of production devices can be avoid, while reducing the total operation cost. |
