Tekniskt potentiell efterfrågeflexibilitet hos industriella elkonsumenter : En fallstudie av SSAB:s produktionsanläggning i Borlänge

Sammanfattning: The power grid faces major and escalating challenges in maintaining the power balance whilst society transitions towards increased sustainability. One promising solution to this challenge is found in the concept of demand response, where consumers adapt their energy demand due to some incentive in order to help balance the power grid. This study analyses the technical potential for industrial energy consumers to provide demand response by combining theory on demand response with theory on operations management and puts this to the test through a case study of a Swedish industrial sheet metal plant. In the study relevant factors such as energy and productivity parameters as well as planning and business models are shown to restrict the demand response potential. Different kinds of load shape objectives are analyzed, where peak clipping is shown to be simple but costly whilst load shifting is shown to be more complex but with the potential of offering demand response without affecting the overall productivity of the plant. These results help expand the picture of industrial consumer demand reponse from a static value depending on the economical incentive into a more complex concept that requires further research and optimization.
