Abstract

The present invention is directed to a power-grid infrastructure for energy as well as methods for efficiently distributing the energy within the infrastructure that rely on a decentralized approach and the use of intelligent agents to facilitate the communication between different levels of the infrastructure as well as the distribution of the energy across the actual electrical couplings within the infrastructure.
