Simulation Study on Flexibilities in the Material and Energy Flows of an Open-pit Mine

Abstract

The progressing introduction of renewable energy sources (RES) in the energy system creates an increasingly difficult market environment for traditional utility companies. While their fossil-fueled power plants are important to secure the supply of electricity, the associated operations are costly and energy intensive. This paper presents a simulation study on an open-pit mine (OPM), where flexibilities are sought for increasing the operator's overall energy efficiency. For this purpose, the OPM's material flows and energy flows are simulated simultaneously. Drawing from discrete production systems in a "cross-learning" approach possibilities for and adjustments to the process control are investigated. Preliminary results show that some opportunities to increase efficiency exist but still require more scrutiny.
