潮流计算收敛性问题研究综述

A study of load flow calculation when power flow does not converge to a solution

阐述了研究电力系统潮流不收敛问题的重要意义,分析了潮流计算不收敛的两种可能性:潮流病态和潮流无解,然后分别从这两个方面进行了综述。文中通过对已有研究方法的比较,总结了其中的不足,并提出几点建议完善潮流计算不收敛问题的研究,最后指出了以后的研究重点。

The importance of non-convergence in load flow calculation is discussed and two possibilities when power flow does not converge to a solution are analyzed, The two possibilities are ill-conditioned power flow and unsolvable power flow. Then a survey from these two aspects is made. After introducing the differences of the existing methods in the literature, the disadvantages of these methods are concluded later. As a result, several suggestions are proposed to improve the research on this problems. At last, this paper points out the key nroblems in the future.
