The wind power has become frequently energy usage in development of green energy. Today, wind turbines which is have sensors and accurate control, Each of turbine blade is continuously adjusted as well. Intelligent controllers expose more of the blade to capture the most wind. If wind mill dangerously strong, the blades can also be rotated to minimize their exposure and the risk of damage. Improvements in weather forecasting are also increasing the output from wind farm. Accurate wind forecasts can increase the power by 10 percent by having a better grip on the wind's intermittent nature. Modern turbines can also provide “ancillary services” such as reactive power and frequency keeping services. These functions help to stabilize the grid or local network a wind farm is connected into, effectively ensuring the lights stay on.
