摘要
针对光伏发电输出功率的随机性和波动性,提出一种适用于光储交直流混合微电网协调控制策略,搭建了光储混合微电网实验平台,完成了硬件电路器件选型和主电路设计,并基于dSPACE1006设计了控制软件,进行了并网模式和孤岛模式下的变载试验。结果表明,所提出的光储微电网协调控制策略可以有效的平滑光伏系统的输出功率,维持交直流母线电压稳定,保证微电网在并网模式和孤网模式下稳定运行。
Focusing on the randomness and fluctuation of the Photovoltaic (PV) power generation output, a new co- ordinated control strategy for PV and energy storage AC/DC hybrid microgrid has been proposed. An experimental plat- form of PV-BESS AC/DC hybrid microgrid has been constructed. The device selection and design for the hardware circuit have been completed. The software has been designed in dSPACE1006, and the changing load experiments in grid-con- nected mode and islanded mode have been performed. The experimental results show that the proposed strategy can smooth the output of PV system effectively, keep the voltage of the DC and AC bus stable, and maintain stable operation in grid-connected mode and islanded mode.
