Energy self-sufficient manufacturing systems – integration of renewable and decentralized energy generation systems

Abstract

Electricity price changes and regulatory operation fees may be non-transparent for manufacturing companies. Furthermore, due to the increasing amounts of renewable energies, grid stability and high grid quality will be less reliable in the future. Taking this into account, self-sufficiency of power supply becomes cost-efficient when being well-adapted to their specific requirements. Therefore, a concept for integration of renewable, decentral energy supply into modern production systems is described. Based on load profiles and further properties of the production system adaptable generation technologies are evaluated. Finally, demand response strategies for energy converters, distributors and storages are applied to minimize the residual power.
