中文摘要：

以电压不越限作为约束条件,将传统的解析法与二分法相结合,有效规避了2种算法各自缺点,提出了用于DG准入容量计算的解析优化二分法。将所提出的方法应用于改进的IEEE 33节点系统。算例表明：该算法在不需要额外增加网络参数的情况下,有效地降低了二分法迭代次数;在保证计算精度的同时,提高了计算速度。

英文摘要：

In order to ensure the voltage constraint was satisfied,analytical and dichotomy was conbined effectively,＂Analytical-improved Dichotomy Method＂ was proposed to solve the problem of calculating the maximum penetration level of DG.The proposed method was applied in the improved IEEE 33 nodes system.The results showed that this method could be quickly and accurately accessed in calculating the maximum penetration level of distributed generators without additional network parements.It was practical in calculting the maximum penertration level of distributed generators.
