Abstract

Smart grid is an electric power network which enables an effective use of electric power in a highly parallel distributed manner. We have first formulated the basic equations for the smart grid by inspiring from the mechanisms in biological organism, and controled the power-flow dynamically in the smart grid by monitoring an objective function, which reflects the power-flow and the constraint imposing on the power nodes. To validate the operation of the smart grid, we performed several simulation experiments: which include the operations of a conventional power network, a microgrid (comprises eight power nodes), and a smart grid (comprises three microgrids integrated into the conventional power network) both in for the operation of power nodes. Furthermore, even for the case of power failure such as outage, power recovery can be automatically achieved through bypass connections similar to synaptic interconnections in a dynamic function of brain. This kind of flexible function in the smart grid makes it possible to promote the introduction of renewable energy, such as solar energy, wind energy, and biomass energy rather than fossil energy.
