Abstract

In order to ensure the robustness of decentralized energy systems and suitable distribution of the energy in such networks to a large number of energy consumption units, the novel energy system is provided with corresponding agents. At least one agent is associated with each energy consumption unit and/or energy generation unit in the decentralized energy system. The agents are interlinked in such a way that each agent can communicate with other agents in the energy system. Each change in the power output or power consumption requires a trade act, as a result of which large balance errors are avoided. In order to make this coupling between electrical and monetary acts practicable, current consumption contracts of an extremely wide variety can be drawn up between generators and consumers. The energy system is configured such that the energy is distributed in the system at least partially on the basis of monetary transactions arranged between the agents.

Claims
