摘要:

为实现“双碳”目标,加快发展风电和太阳能等新能源是我国能源绿色低碳转型的必然选择。风能的波动性和随机性会对电网的安全稳定运行造成威胁,实际应用中往往将风力发电与储能技术相结合,相比于传统的风力发电,可在一定程度上减小系统输出电能对电网的冲击。建立了海上风电-水下压缩空气储能系统模型并以此作为研究对象进行系统模型的仿真与分析,采用随机概率和真实数据拟合相结合的方法对系统的能效、经济性进行分析。结果显示:在风速随机波动的条件下,系统发电效率可达65%,理论平均收益为11 675 元/d,在有效寿命期20 a内总利润可达1 346万元。

Abstract:

On the path of dual carbon target, developing new energy, such as solar power and wind power, is the inevitable approach to realize the green and low-carbon transformation of the energy industry in China. But the volatility and randomness of wind energy will threat the stability and security of power grids. Thus, energy storage technology is applied in combination with wind power in practical applications, to smooth the power output from wind farms and alleviate the impact on power grids. The model of an offshore wind power-underwater compressed air energy storage system is established and simulated. The energy efficiency and economic benefit of the system are analyzed by combining random probability calculation and real data fitting. The results show that under volatile wind speeds, power generation rate and theoretical average return of the system can reach 65% and 11 675 yuan/d, respectively, and the total profit of the system can be 13.46 million yuan in its 20-year service life.

Key words: carbon neutrality, new energy, offshore wind power, underwater compressed air energy storage, energy efficiency, economic benefit analysis
