Integrating Energy Storage into Shopfloor Dispatching: A Threshold-Based Energy-Aware Control Approach

Rising energy price volatility and the shift toward renewables are driving the need for energy-aware production planning. This paper investigates the integration of energy storage systems into dynamic dispatching to balance production-logistics and energy costs. Building on prior work that introduced a workload- and price-based dispatching rule, we extend the model to include energy storage loading and unloading decisions. The rule prioritizes storage refill at low prices and lets machines resort to stored energy when grid prices rise and the workload is high. A simulation-based evaluation examines scenarios with different storage capacities whereby decision rule parameters are optimized. Computational results demonstrate that a reduction of operational costs is possible without deteriorating production logistics performance. By decoupling energy sourcing from real-time prices, manufacturers achieve both resilience and cost savings. This research contributes to sustainable manufacturing by offering a practical strategy for integrating energy storage into production planning under volatile energy conditions.
