摘要
介绍了直流微电网的结构和控制方法,分析了直流微电网在某智能楼宇中的实践与应用,经过与不同楼层的交流电网进行综合对比分析,结果表明从光伏发电至负载端,直流微电网比交流微电网的光能利用率高,而且电网运行可靠性更高。
The structure and control method of DC microgrid were introduced.The practice and application of DC microgrid were analyzed in a building grid.Through the comprehensive comparative analysis between DC microgrid and AC power grid with different floors,the results show that the DC microgrid has the higher light energy utilization ratio than AC power grid from photovoltaic power generation to load end,and the DC microgrid operation is more reliable.
