摘要
风光发电出力的不确定性和电力存储困难制约着新能源的发展.氢能作为一种优质二次能源,具有绿色无污染和能量密度大的优点.为应对新能源出力的波动性与随机性,提出一种考虑氢储的风光氢综合能源系统多时间尺度随机生产模拟方法.首先,考虑在氢储系统模型中加入热能回收环节,构建包含电热氢多元储能的风光氢综合能源系统模型;其次,对风光氢综合能源系统进行多时间尺度随机生产模拟,通过中长期生产模拟得到系统检修安排与氢储季节分配方案,并将中长期模拟结果作为边界进行短期生产模拟,实现电氢热多元储能相互配合平抑风光随机波动性.最后,利用IEEE-RTS79节点算例验证所提方法能够提高系统运行的可靠性、灵活性、低碳性.
The uncertainty of wind power output and the difficulty of power storage restrict the development of new energy.As a high-quality secondary energy,hydrogen energy is green and pollution-free and has a high energy density.In order to cope with the volatility and randomness of new energy output,this paper proposes a multi-time scale probabilistic production simulation method for wind-solar hydrogen integrated energy system considering hydrogen storage.First,thermal energy recovery is considered in the hydrogen storage system model,and the wind-solar hydrogen integrated energy system model including electrothermal hydrogen multiple energy storage is constructed.Then,multi-time scale probabilistic production simulation is conducted for the wind-solar hydrogen integrated energy system,and the system maintenance arrangement and hydrogen storage seasonal distribution scheme are obtained through medium and long-term production simulation.The simulation results are taken as the boundary for short-term production simulation to achieve the cooperation of electrothermal hydrogen multiple energy storage and to smooth the random fluctuation of wind and solar power.Finally,an IEEE-RTS79 node example is given to verify that the proposed method can improve the reliability,flexibility and low-carbon feature of system operation.
