M * M R A N G E Renewable energy sources a challenge for power grids ABB provides reliable stability for you Weather conditions can mean generators need to feed several gigawatts of renewable power into the pubic grid within a short time. These sudden power increases can exceed the grids power control capabilities. The rise of renewable energy sources The rapid expansion of fluctuating renewable energy sources like wind turbines and solar power plants has had a dramatic effect on our power grid. Instead of a relatively small number of high capacity generating plants there are now thousands of small renewable power sources. Influence of fluctuating energy input A sudden power rise, for example on an especially windy day, might exceed the grid power control capabilities. To stabilize the grid, renewable power plants must be disconnected so that the energy generated and the energy consumed can be balanced. Depending on weather conditions, several gigawatts of renewable power might be fed into the public grid within a short time. If both are not in equilibrium, the frequency increases or decreases in the public network, increasing the risk of a blackout. Sudden changes in weather conditions can affect the amount of power being fed into the grid Renewable energy...
