Security-constrained Unit Commitment Considering Load Transfer of Large Industrial Consumers

  • 摘要: 工业大用户中的一些负荷可以在不影响整体生产流程的情况下在一定时间范围内移动。这些可转移负荷被看作是启动时间可调节的。本文计及工业大用户可转移负荷的运行特性,建立了考虑工业大用户负荷转移的安全约束机组组合模型。该模型的目标函数为发电成本和负荷转移成本综合最小,在传统安全约束机组组合的约束条件中增加负荷转移相关约束。所建立的模型是一个混合整数线性规划模型,可以调用商用求解器求解。算例分析结果表明机组组合和可转移负荷的联合优化,能够改善系统负荷的峰谷差,降低系统运行的总成本,验证了本文所提出模型和方法的有效性。
    Abstract: Some loads of large industrial consumers can be transferred within a certain time range without affecting the overall production process. The start-up time of these loads are considered to be adjustable. In this paper, the model of security-constrained unit commitment considering load transfer of large industrial consumers is proposed by taking operation characteristics of transferable loads into account. The objective function of this model is to minimize the total cost of power generation and load transfer, and constraint of load transfer are integrated into the constraints of traditional security-constrained unit commitment model. Therefore, the model is a mixed integer linear programming formulation, and a commercial solver is used to solve it. In the end, the results of case study show that the coordinated optimization of unit commitment and transferable loads can decrease the system load difference between peak and valley and reduce the total cost of system operation, which shows that the proposed model and method are effective.
