Self-organization of electric power grid dynamics
In future smart grids, the distribution of consumer demands shall be controlled as to efficiently match electric power production. Such control requires a through understanding of how the grid self-organizes its collective dynamics in the absence of control. We are now providing a new perpective using mathematical oscillator models of power grids.
One main conclusion: adding new connection lines may not only help but also prevent power grid synchrony and thus cause power outage.
