Activating Industrial Energy Flexibility in Production Planning: A Systematic Pre-Evaluation for Digital Twin-Based Optimization

Addressing grid instability from renewable energy, this paper introduces a method to leverage industrial energy flexibility for both electricity markets and grid support. We propose a pre-evaluation framework to assess the technical and economic potential for energy flexibility within industrial production, paving the way for a digital-twin-based optimization. This method systematically identifies flexible assets and quantifies load-shifting potential. A case study validates the approach, demonstrating successful quantification of economic benefits and providing a roadmap for future implementation of a digital twin framework. This work lays the foundation for integrating industrial energy flexibility into emerging energy markets.
