Abstract: | Implementing industrial energy flexibility is a complex challenge within complex production systems. To successfully utilize energy flexibility, it is crucial to ensure product quality, manage production schedules, and understand systemic dependencies. By adapting production processes to volatile energy prices, industrial energy flexibility makes it possible to reduce costs without compromising productivity and minimize the carbon footprint by using renewable energy efficiently. In addition, energy flexibility opens up potential revenue opportunities by trading flexibilities in future dynamic energy systems and markets. One of the most important aspects of this adaptability is the use of a standardized data model to identify and model flexibilities. However, the complexity of industrial processes and the need for extensive domain knowledge make it difficult to model all relevant production assets. This thesis presents a methodology that simplifies the modeling process for describing energy flexibility. Therefore, the aim of the thesis is to develop an automated parameterization methodology for an energy flexibility model, hypothesizing that data-driven, automatically parameterized models and machine learning techniques can be used. Using the Design Research Methodology, this thesis provides a comprehensive understanding of the current state of science and technology related to industrial energy systems, digital production, and energy flexibility modeling. The research identifies a research need in this area, formulates research questions and hypotheses, and develops the Data-Driven Energy Flexibility Modeling (DD-EFMod) method. This method is validated using a use case that confirms the feasibility of using data analytics and machine learning algorithms to parameterize energy flexibility, with batch clustering methods showing promising results. In addition, the work shows the energy and cost savings through energy-flexibility measures based on the detailed modeling of energy flexibility. The prototypical application use case at the ETA Research Factory shows that the energy-flexibility measure change processing sequence enables cost savings of 9.2%. Additional cost savings of up to 69.4% was achieved through a combination of the energy-flexibility measures change processing sequence and shift start of job within the validation of the use case. |
