Study: Solar and wind energy may stabilize the power grid

September 14, 2012 8:49 am | News | Comments

If increasing numbers of wind turbines and photovoltaic systems feed electrical energy into the energy grid, it becomes denser—and more distributed. Researchers in Germany, using model simulations, have discovered that consumers and decentralized generators can easily self-synchronize. Their results indicate that a failure of an individual supply line in the decentralized grid less likely implies an outage in the network as a whole. But care must be taken when adding new lines.
