摘要

针对可再生能源输出功率波动性大且随机性强的特点，在计及储能电池使用寿命等约束条件的基础上，提出了一种基于实测电池荷电状态的可变滤波时间常数储能控制方法。该方法通过实时调节储能系统的输出功率，对可再生能源输出功率中某一特定频段的波动成分进行补偿;同时根据电池的荷电状态值，对滤波时间常数进行调节，从而使电池的荷电状态值稳定在一定的范围内，避免了电池的过充/放电。在PSCAD中搭建的光储系统仿真模型，验证了所述方法的有效性。

Abstract

According to the large fluctuations and strong randomness of the output power of renewable energy， taking into account the constraints such as battery life cycle， an energy storage control method based on real-time state of charge and variable filter time constant is presented. This method can compensate the fluctuation composition of a particular frequency band in the output power of renewable energy by real-time regulating the output power of energy storage system. At the same time， filter time constant is adjusted according to the state of charge in order to stabilize the value of batterys state of charge in a certain range， while the over-charging and over-discharging of the battery is avoided. A photovoltaic and battery storage system simulation model built in PSCAD shows the effectiveness of the proposed method.
