摘　　要：基于近似牛顿方向,提出了一种求解动态无功优化问题的解耦算法。将修正方程解耦分解成若干个独立的子修正方程,并对求得的近似牛顿方向用广义最小化残差(GMRES)算法进行修正,保证了算法的收敛性。以广州鹿鸣电网作为算例进行优化计算,取得了理想的结果,并与非解耦算法的结果进行了比较分析,验证了该算法的正确性和可行性。Based on approximate Newton direction,a decomposition dynamic reactive-power optimization method is introduced in this paper.This method decomposes the high-dimension linear correction equation into several sub-correction equations and uses generalized minimal residual algorithm（GMRES） to modify the approximate Newton direction for ensuring the algorithm＇s convergence.Case studies are performed on the local power supply network of Guangzhou to validate correctness and effectiveness of the proposed method,and the results of this method are compared with that obtained by conventional non-decomposition approach.
