摘　　要：在光伏发电系统中引入储能技术,为平抑光伏出力的波动提供了可能,合理选择储能容量必须顾及光伏出力波动性要求及电站的经济运行。因此,在考虑调度计划的前提下,提出了一种成本经济函数,该目标函数可充分保证光伏电站的经济性,并最大程度地满足调度中心对于光伏出力波动性的限制,使光伏电站功率尽可能平滑、稳定地输出。通过对该目标函数的优化,确定最优储能容量,并通过算例对不同波动性要求下的储能容量进行了计算比较。The possibility to stabilize photovohaic （PV） output is acquired by introduction of photovohaic energy storage technologies; requirements for fluctuation restraining of PV output and economic operation of PV plant with energy storage are taken into account for a reasonable choice of storage capacity. Therefore, under the condition of scheduling, a cost economy function is proposed in this paper. The objective function can achieve economic operation of PV plant, and satisfy fluctuation restraining demand of scheduling center as much as possible, which makes PV output smoother and more stable. By optimizing the objective function, an optimal storage capacity is determined in this paper. Examples calculating and comparing of the optimal storage capacity are carried out under different fluctuation demands.
