Abstract

A dynamic network for energy-distribution can comprise energy converters, communication-and-control modules, power distribution switches, energy storage batteries, light emitters and light receivers located at spatially separated sites connected by optical transmission media, wherein each site can be equipped with energy transmitting, receiving or storage functionalities as well as signal-communication functionalities. The topology of the energy-distribution network can be changed dynamically by activating or deactivating optical links among the sites via software control. Charging vehicles can act as moving sites to remotely deliver energy to or receive energy from devices located at different sites of a network.
