摘要
建立合理的蓄电池动态模型对于研究其在微电网运行时的动态性能具有十分重要的意义。介绍了一种基于铅酸蓄电池的3阶动态模型,并在MATLAB/SIMULINK平台中建立了相应的仿真模型,分析了该模型在充放电过程中的动态特性。基于P/Q解耦控制原理实现了蓄电池并网,并将蓄电池应用于平抑分布式电源的功率波动。仿真结果验证了模型的合理性及控制策略的有效性。
For the study of dynamic performance of microgrid operation, to establish reasonable battery dynamic model is very meaning- ful. Introduction was made to a kind of three-order dynamic model based on lead-acid batteries and the corresponding simulation model was established in SIMULINK of MATLAB to analyze the dynamic characteristics of the model in the process of charging and discharging. On the basis of P/Q decoupling control principle, the battery energy storage system was connected to the grid and would be applied to stabilize the power fluctuations of distributed power. Simulation results verify the validity of the model and control strategy.
