Decentralized energy management in automated industrial installations using self-organizing networks
First Claim
1. A method for proactively regulating energy flows in an electrical supply network of an automated industrial production plant comprising a conveying installation including workstations interconnected by conveyor belts and having a plurality of connecting devices which are each connected to the supply network, and a plurality of the connecting devices of the conveying installation having an electric motor serving as a generator or as an electric drive, wherein depending on an operating mode of the electric motor, the plurality of connecting devices of the conveying installation exchange information with respect to their energy requirement or their energy supply with one another, the method comprising:
- exchanging, among the plurality of connecting devices of the automated industrial production plant comprising the conveying installation including the workstations, information on an expected variation over time of an energy requirement or energy supply of the plurality of connecting devices of the conveying installation; and
exchanging, among the plurality of connecting devices of the automated industrial production plant comprising the conveying installation including the workstations, energy based on the expected variation over time of the energy requirement or energy supply information;
wherein the information is formed as broadcast messages in accordance with the PROFINET standard;
wherein each of the plurality of connecting devices of the automated industrial production plant comprising the conveying installation including the workstations serves as one of (i) an energy consumer, (ii) an energy producer and (iii) an energy store;
wherein energy flows are regulated such that an energy requirement of energy consumers is covered primarily by an energy supply of energy producers;
wherein the energy supply of the energy producer is fed directly to the energy consumer without being temporarily stored; and
wherein the plurality of connecting devices of the automated industrial production plant comprising the conveying installation including the workstations form a self-organizing device network which functions without a central coordinating energy control unit.
