The method of ERPC(Equivalent reactive power compensation) is improved to measure the difference among reactive resources.An average method is proposed to define reactive value factors which are introduced to the OPF(Optimized power flow) model.The real-time pricing model of reactive power is presented which involves both reactive power cost and adjustment of reactive power value factors.The simulation result in the Wald-Hale 6-bus system shows this model makes the system get more reactive power from generations with larger value and it also improves security and stabilization of power system.
