Abstract


Industrial compressed air systems (CAS) embrace significant potential for saving both energy and cost due to their share of 7 % of the total industrial electricity consumption in Germany. In electric energy systems based on renewable generation plants supply and demand often do not occur in the same period of time. Consequently demand side management (DSM) is gaining importance whereby decentralized automation offers opportunities in industrial environments. Supply systems on industrial plants supply manufacturing equipment with compressed air, nitrogen and other technical gases, which partly can be obtained from air by deposition processes. Those systems consist of air compressors, gas separators, reservoirs and lines. With suitable dimensioning and by equipping with automation technology those systems can be used for demand side management purpose. In addition to basic operating parameters like current air pressure and status, those systems can process further information and create, for example, profiles on compressed air consumption over time. By enriching those profiles with data on pressure, volumes, system restrictions and current production requirements, the system control can identify the available potential for demand side management. Evaluation of operational strategies has to optimize conflicting objectives within the triangular relationship of storage design, control of the production according to price prospects and influencing or predicting the use of compressed air and technical gases obtained from air. For economical advantageousness of cyber- physical supply systems time flexible procurement prices for electric energy are required, enabling the utilization of use low prices in times of high supply. Costly production downtime due to inactive supply, caused by high electricity price has to be avoided mandatorily. Within the article, a conceptual approach for connection of CAS to production planning systems (PPS) will be presented and challenges as connecting demand forecasting and compressor control will be outlined.
