随着光伏发电装机容量的不断扩大，其输出功率的随机性和间歇性给电网稳定运行带来了严峻挑战，配置电池储能系统成为解决这一问题的重要技术途径。本文主要探讨了兼顾平抑效果和电池健康状态的储能控制策略，从而提高光储系统的综合运行效益。从光伏功率波动特性对电池循环寿命的影响机理出发，可建立基于雨流计数法的电池寿命损耗模型。在此基础上，本文提出自适应平抑控制策略，通过动态调节滤波时间常数，并结合荷电状态与充放电倍率的双重限制，实现储能出力的最优分配。

With the continuous expansion of photovoltaic power generation capacity, the randomness and intermittency of output power pose significant challenges to grid stability. Deploying battery energy storage systems has become a critical technical solution to address this issue. This paper primarily explores energy storage control strategies that balance smoothing effectiveness and battery health status, thereby enhancing the overall operational efficiency of photovoltaic-storage systems. power fluctuations affect battery cycle life, a battery life degradation model based on the Rainflow method is established. Building upon this, an adaptive smoothing control strategy is proposed. By dynamically adjusting the filter time constant and incorporating dual constraints on state of charge(SOC) and charge/discharge rate, optimal allocation of energy storage output is achieved.
