摘要
利用PSCAD建立了一个含有风力发电机、光伏阵列、蓄电池及负荷的微电网模型。其中并网运行时,微电网中的风机和光伏电池采用P/Q控制模式或最大功率跟踪模式;孤网运行时,系统采用主从控制模式,蓄电池作为主控单元,采用V/f控制方式。利用建立的模型,对微电网两种运行模式及切换时的过渡状态进行了仿真分析。仿真结果验证了所建立的模型及控制策略的可行性和有效性。
A microgrid model, containing wind turbine, PV arrays, battery and load, is established by using PSCAD. In the process of grid-connected operation, the microgrid wind turbine and PV cells adopt P/Q control mode or tracking control mode with maximum power; in the process of island running, the system uses master-slave control mode, where the battery is the main control unit taking V/f control mode. Based on this model, the simulation of two operation modes and transition state during the microgrid mode-switch is conducted, and the results verify the feasibility and validity of this proposed model and control strategy.
