The renewable sources and their share in electricity production have been increased constantly in recent years. The renewable sources, such as wind, are influenced by atmospheric turbulence, which cause frequent extreme events in power output of wind turbines. Such events can influence the stability of power grids and especially can cause voltage instability in very short term scales. Therefore, understanding and characterization of stochastic behavior of power output has great scientific and practical importance. Our aim is to show that such extreme events are intelligible from interactions between wind turbines in different time intervals. For this purpose, we investigate the power synchronization of different turbines and show that synchronization can explain extreme events in this complex system.
