ABSTRACT
Wind power, one of the most appealing renewable energy resources, grew rapidly during the last decades. Currently, an increasing number of wind turbines have been installed all over the world. One of the major challenges is to adopt appropriate strategies to smooth the wind power output due to the intermittent and stochastic characteristics of wind resources, The power output increases linearly as the wind speed increases from the cut-in wind speed to rated wind speed. However, when the strong wind speed exceeds the cut-out wind speed, wind turbines are forced to shut down to avoid damage to the structure due to excessive mechanical loads. The wind power output fluctuation due to the volatile and stochastic characteristic of wind speed may gradually threaten the secure and stable operation of the power system. The previous study mainly focuses on the probability analysis when the WTs functions normally and the output wind power is available, however, the operation status of WTs and wind power output fluctuation under adverse condition are seldom discussed. In wind resources abundant area, the extreme weather event is not unusual, the power reduction caused by such extreme wind condition is worth studying.
