摘要
电池储能(BES)可为电力系统提供快速的响应容量,能有效提高电力系统的稳定性、可靠性和电能质量。为了研究电池在电力系统中的应用,必须建立准确的电池模型。本文在铅酸蓄电池动态模型的基础上进行简化,得到只与荷电状态(SOC)相关的、适于电力系统电磁暂态分析的简化电池模型。仿真结果验证了模型的有效性。
The battery energy storage(BES)could supply fast response capacity for the power system,thus effectively enhancing the stability,reliability and power quality of power grid.For these application researches,an accurate battery model is necessary.In this paper a simplified battery model is proposed for power system electromagnetic analysis based on the dynamical model of lead-acid battery.The parameters of the simplified model are merely related to the state of charge(SOC)of the battery.The simulation results verify the effectiveness of the model.
