摘要

从化石燃料向可再生能源的过渡给平衡日益受天气影响的电力供需带来了重大挑战。尽管需求方能源灵活性(尤其是工业企业提供的灵活性)被视为应对这些挑战并为企业带来效益的一种有前途且必要的方法,但其实施尚未普及。通常情况下,面对高度复杂的流程景观和运营系统,流程挖掘在提高实际流程的透明度、发现或反映活动、实例或资源的现有依赖性和相互关系方面具有巨大潜力。它有助于实施能源灵活性措施,并实现与灵活流程操作相关的货币收益。本文介绍了一种名为 PM4Flex 的设计科学研究工具,有助于将能源灵活性成功整合到流程操作中。这是一种规范性流程监控方法,它使用线性规划来生成建议,以便在电价波动的情况下,利用既定的能源灵活性措施优化待定流程。因此,要考虑事件日志和相应的公司以及特定流程约束条件。PM4Flex 的演示和评估基于其作为软件原型的实施、对来自两个真实世界流程的示例数据的应用(与原始执行相比,可节省高达 75% 的电力成本)以及半结构化的专家访谈。PM4Flex 在规范性过程监控和能源领域的界面上提供了新的设计知识,为优化工业能源采购成本提供了决策支持。

Watt’s Next? Leveraging Process Flexibility for Power Cost Optimization

The transition from fossil fuels to renewable energy sources poses major challenges for balancing increasingly weather-dependent power supply and demand. Although demand-side energy flexibility, offered particularly by industrial companies, is seen as a promising and necessary approach to address these challenges and realize benefits for companies, its implementation is not yet common practice. Often facing highly complex process landscapes and operational systems, process mining provides significant potential to increase transparency of actual process flows and to discover or reflect existing dependencies and interrelationships of activities, instances or resources. It facilitates the implementation of energy flexibility measures and enables the realization of monetary benefits associated with flexible process operation. This paper contributes to the successful integration of energy flexibility into process operations by presenting a design science research artifact called PM4Flex. This is a prescriptive process monitoring approach that uses linear programming to generate recommendations for pending process flows optimized under fluctuating power prices by utilizing established energy flexibility measures. Thereby, event logs and corresponding company- as well as process-specific constraints are considered. PM4Flex is demonstrated and evaluated based on its implementation as a software prototype, its application to exemplary data from two real-world processes exhibiting power cost savings of up to 75% compared to the original execution, and based on semi-structured expert interviews. PM4Flex provides new design knowledge at the interface of prescriptive process monitoring and the energy domain providing decision support to optimize industrial energy procurement costs.
