摘　　要：柔性直流电网由于其安全的特性以及对新能源电能的兼容性而被称为“未来的电网”。文章在多电压需求条件下,对当前柔性直流电网的组网方式进行了简要介绍,并按照用电端定功率和发电端定电压两种路径构建了柔性直流电网模型。通过建模与仿真发现柔性直流电网能够在多电压等级情况下满足稳定且高质量的供电需求,适宜于后续推广使用。Flexible DC power grid is called“future power grid”because of its safety characteristics and compatibility with new energy sources.Based on this,this paper briefly introduces the networking mode of the current flexible DC power grid under the condition of multi-voltage demand,and constructs the flexible DC power grid model according to the two paths of fixed power at the power end and fixed voltage at the power generation end.Through modeling and simulation,it is found that the flexible DC power grid can meet the stable and high-quality power supply demand under the condition of multi-voltage level,which is suitable for subsequent popularization and use.
