【摘要】 为了抑制光伏、风力发电等间歇式可再生能源输出波动对电网的不利影响,本文提出了用于平滑可再生能源功率输出的储能系统容量优化确定方法。基于可再生能源频谱分析结果,可优化选取满足经储能系统补偿之后目标功率输出波动率约束的储能系统最小容量。算例验证了方法的有效性。更多还原

【Abstract】 A capacity determination method of energy storage system(ESS) in power smoothing operation mode for renewable energy sources(RES) is presented in order to inhibit the adverse effects of its fluctuations on the power grid.The minimum power and energy capacity of ESS that meet the power fluctuation constraints of combined output(the sum output of ESS and RES) can be determined based on output spectrum analysis of RES.The results of case study prove the method proposed in this paper is effective.更多还原
