Wind curtailment of China׳s wind power operation: Evolution, causes and solutions

Since 2010 China has faced a worrying phenomenon “wind curtailment” in the development and operation of the wind power industry. This phenomenon has resulted in sharp decline of the utilization hours of the wind power equipment, seriously affected the economic benefits of the wind farms and caused serious energy waste. The wind curtailment in China is seemingly caused by the volatility of the wind power technical characteristics. However, judging from a deep level, the planning, networking management and policies play a critical role. With analysis this paper makes such a conclusion: it is not practical to solve the wind curtailment of China solely with the technical solutions and comprehensive measures must be taken. The paper offers strategies from the planning, policy and technical levels to solve the wind curtailment problem according to the actual situation of China and by referring to experiences of developed countries.
