论文摘要
设计了增强的微电网功率流（EMPF），以纳入层次控制效果。新的贡献是三重的：1）建立了基于高级层次控制的牛顿方法，以准确评估电源共享和电压调节效应； 2）得出一个修改的雅各布矩阵，以结合下垂控制和各种二级控制模式； 3）次级调整是在基于下垂控制的功率流的顶部计算出的，以确保纽顿的强大解决方案。案例研究验证了EMPF有效而有效，可以作为微电网操作和监测的强大工具，尤其是对于城市地区高度网状的微电网而言。
An enhanced microgrid power flow (EMPF) is devised to incorporate hierarchical control effects. The new contributions are threefold: 1) an advanced-hierarchical-control-based Newton approach is established to accurately assess power sharing and voltage regulation effects; 2) a modified Jacobian matrix is derived to incorporate droop control and various secondary control modes; and 3) the secondary adjustment is calculated on top of the droop-control-based power flow results to ensure a robust Newton solution. Case studies validate that EMPF is efficacious and efficient and can serve as a powerful tool for microgrid operation and monitoring, especially for those highly meshed microgrids in urban areas.
