摘　　要：风电的波动性与间歇性给风电并网发电带来巨大影响,而储能技术是解决该问题的主要技术之一,通过储能系统可有效改善风电并网不稳定性问题。储氢-氢氧联合循环系统通过电解水将不稳定风能转化为氢能,进行能量储存,在用电高峰期通过氢氧联合循环将氢能转换为稳定的电能,从而实现风电的安全并网。选取某风电场作为案例,通过Aspen建模分析,结果显示该储能系统能明显降低风电的不稳定性,且系统易规模化,无污染,可将间歇性风电在一定时间内转化为稳定电力输出,从而实现大规模风电并网发电。Energy storage system is one of the best solutions for the variability and intermittence performance of wind power connected to power grid.This paper proposes a hydrogen storage system as a means of energy management,the power is stored as hydrogen by an electrolyzer set,and generates electricity to the power grid by hydrogen-oxygen combined cycle during the peak hours.The paper makes a case study for a special wind power plant,and a modeling analysis of the systems by Aspen shows that the energy storage system is absolutely environmental friendly and efficient,can reduce the instability of the wind power and convert the intermittent wind power to stable power in a certain period of time.Therefore,the energy storage system can be useful for breaking the bottleneck of wind power development.
