| Abstract: | The classification and analysis of nonlinear error of classical Ward equivalent are done An improved extended Ward method, where the effect of some important external shunt reactive compensators on internal network can be considered accurately, is proposed Some results of numerical tests are presented The practical application of the improved extended Ward method to the EMS in He'nan power system control center in China is reported |
