【摘要】 灵活负荷的调节边界是电网安全运行需提前掌握的关键数据之一。对于面向过程工艺的流程工业(process industry,PI),其全工序负荷调节能力的准确评估受到多能源需求与工序耦合,以及必须满足的流程工艺要求与生产任务等因素限制。为此,提出一种考虑工序精细化建模的PI全工序负荷调节能力评估方法,为电网制定需求响应策略提供边界值参考。首先分析典型PI生产流程,基于工序调节特性建立考虑工序分类的通用化PI等效模型,并提出精细化工序分类建模方法;其次,计及工序耦合、多能源利用、生产计划等多方面生产约束,建立PI全工序负荷调节能力评估模型;最后以水泥工业为例对所提方法的有效性进行验证,探究了工序调节对PI全工序负荷调节能力的影响。

【Abstract】 The regulation boundary of adjustable load is one of the key data that needs to be mastered in advance for the safe operation of the power grid. For process-oriented processing industry(PI), the accurate evaluation of its whole-process load regulation capacity is limited by multiple energy requirements and process coupling, as well as the process requirements and production tasks that must be met. To this end, a method to evaluate the whole-process load regulation capacity of PI considering the refined modeling of processes is proposed,which provides a boundary reference for the power grid to formulate the regulation plan. Firstly, the production process of typical PI is analyzed, and an equivalent model of generalized PI considering process classification is established based on the adjustment characteristics of processes, and a refined modeling method considering process classification is proposed. Secondly, considering the production constraints such as process coupling, multi-energy utilization, and production planning, the model to evaluate the whole-process load regulation capacity of PI is established. Finally, the effectiveness of the proposed method is verified by taking the cement industry as an example,and the effect of process regulation on the whole-process load regulation capacity of PI is explored.
