摘　　要：气象因素变化以及负荷突变等情况都会影响微电网的稳定运行,本文提出基于超级电容器和全钒液流电池的两层混合储能控制策略。以某园区实际需求为依据,在MATLAB/Simulink仿真环境下建立风光储荷微电网运行系统仿真模型。将典型日的实测风速和光照数据导入模型,分析负荷突变工况下微电网系统并网、离网模式运行状态。仿真结果表明:混合储能可以有效地维持微电网稳定运行,在系统受到干扰后,能快速找到平稳点,从而实现功率平稳输出。The stable operation of microgrid can be affected by the change of meteorological factors and the sudden change of load.A two-layer hybrid energy storage control strategy based on super capacitor and vanadium redox flow battery is proposed in this paper.Based on the actual demand of a park,the simulation model of wind/photovoltaic/storage/load microgrid operation system is established in MATLAB/Simulink simulation environment.Finally,the measured wind speed and light data of typical days are imported into the model to analyze the operation state of the system under such conditions as external environment change and sudden load change.The simulation results show that the hybrid energy storage can effectively maintain the stable operation of the microgrid,and can quickly find the stable point after the system is disturbed,so as to realize the stable power output.
