基于逐次逼近法的虚拟阻抗调节方法实现孤岛微电网无功功率精确分配

Due to the mismatched line impedances in islanded microgrids, distributed generation units with conventional droop tend to have barely satisfactory reactive power sharing accuracy. To handle this problem, this article proposes a virtual impedance tuning method based on successive approximation to accurately compensate the mismatch among line impedances. First, in each distributed generation (DG) u...
