Var optimization is core problem of voltage stability and economic operation of electric power system, also important measure to improve voltage quality. This paper introduces briefly the classical arithmetic: Grades, Newtons,Sequential Quadratric, Programmings,and Linearity Programings Agorithm. It analyzes particularly the application of Artifical Intelligence methods, compares the basic thoughtfulness of GA,SA,Tabu,TS,ES,ANN and Dynamic Programming,etc. The paper takes reasonable conclusion finally: GA and their combination method will play a more important role in appliance region of var optimization and controlling.
