Service Architecture for Integrating Energy-Flexible Production Rescheduling into Production Planning and Control Systems via the Energy Flexibility Data Model Tobias Koch, Andreas Clement, Daniel Fuhrländer-Völker, Florian Faatz, Matthias Weigold

Abstract

As the share of renewable energy increases, demand-side flexibility becomes essential. Integrating energy considerations into Production Planning and Control (PPC) systems offers great potential, yet most existing PPC solutions lack this capability. To address this gap, we adopt the approach to treat Energy Flexibility (EF) as an add-on to PPC systems, enhancing rather than extensively modifying or replacing established scheduling processes. We refer to this approach as Energy-flexible Production Rescheduling (EFPR). This paper presents a service architecture for EFPR that supports selected EF measures and objectives. It defines the requirements, describes the needed services and modules as well as PPC system extensions and outlines their interconnections. The Energy Flexibility Data Model (EFDM) is used to standardize the description and exchange of EF information, enabling a factory-wide EF management. The architecture is transferred to a research factory, seamlessly integrating with both the production line and a commercial PPC system, demonstrating the practical applicability and potential of EFPR.
