Mapping of feed-in and customer systems in the master data system

The mapping of sub-systems to higher level systems in the master data system essentially involves the introduction of two types of sub-system, feed-in and customer systems. The feed-in system can also be created without a higher level system and is primarily used for the generation of electricity and feeding it into the public distribution network. In the system landscape of the customer, technical systems are regarded as feed-in systems, if they can serve this purpose under the terms of the legal regulations (subsidies). However, electricity from renewable energies can also be immediately consumed at the place where it is generated. Maintenance of data relating to the feed-in and mapping of the associated processes are required to create the preconditions for direct marketing of the electronic energy in accordance with the market premium model. A customer system is a system located within a plant that is supplied with energy, such as a backer in a discount supermarket.
