摘　　要：储能系统是微型电网正常运行的关键环节之一。为满足微型电网对储能系统的要求,这里选择铅酸蓄电池作为储能装置。铅酸蓄电池能量密度大、成本低且控制技术相对成熟。通过双向DC/DC变换器和所提出的蓄电池控制策略,成功地实现了蓄电池的能量管理。Matlab/Simulink的仿真结果及微型电网3 kW小功率样机实验充分验证了电路拓扑和控制策略应用于微型电网的合理性和实用性。Energy storage system is one of the vital parts in a microgrid.Compared with other kinds of energy storage devices, Lead-acid battery finally is chosen for its high energy density and low price.To fulfill the requirement of the microgrid to the storage system, a bi-directional DC/DC converter is chosen and designed.To make sure the battery working in a proper way including charging and discharging, a control strategy is also proposed.In the end, simulation and experimental results are displayed which prove that the storage system and the control strategy are applicable and effective for the microgrid.
