reactive power optimization ( rpo) of power system can effectively reduce the energy losses caused by power transmission and distribution, which can not only improve voltage quality and power system stability obviously, but also economize energy.

the methods of rpo are presented in this paper, kinds of methods for solving the problem are summarized. the methods fall into two categories, one is the classical methods, the other is the modern methods.
