摘要
考虑光伏发电具有间歇性,用蓄电池储能系统和氢气发生器来调节并网功率,以提高光伏并网运行的稳定性.在光伏发电系统中安装一个高纯度氢氧发生器来产生氢气.用PSCAD/EMTDC对具有储能单元的光伏发电系统进行了建模和仿真.结果表明:在光照强度变化的情况下,采用四象限变流器控制的蓄电池储能系统能够快速平滑光伏发电系统输出的有功功率的波动.
Considering the intermittent property of photovoltaic generation, the battery energy storage system combined with hydrogen generator were used to adjust the grid-connected power for improving the stability of photovoltaic grid-connected operation. The hydrogen generator was installed in photovoltaic generation system to generate high purity hydrogen. The photovoltaic generation system including energy storage unit were modeled and simulated using PSCAD/EMTDC. The simulation results verify that the battery energy storage system adopting four-quadrant converter control is able to quickly smooth the fluctuation of active power output of photovoltaic generation system.
