【Abstract】 The definition and algorithm of sensitivities of the dominant eigenvalues with respect to the power flow on the interconnection(SDEPF)or a main transmission line of power system are proposed. And it is pointed out that the sensitivities are relative, that is, while regulating different couples of generator active powers (it is called as active power-control couple), the SDEPFs are also different. Regulating the active power-control couples corresponding to the greater absolute value of the SDEPFs, there are greater influences on the dynamic stability of the power system. The study of this paper provides a means of calculation and analysis for comprehensive optimal control of the interconnection.更多还原
