Abstract

In view of voltage stability problem

a new kind of reactive power control strategy for the voltage stability based on the trajectory sensitivity analysis method is proposed.With the use of this method

the optimal reactive power compensation point can be located quickly and amount of reactive power compensation can be calculated directly by use of sensitivity information.The method posses such features as simple procedure

small amount of calculation and correct control result.The high efficiency and correctness of the proposed method is verified by the calculation in new England 10-machine 39-node power system.
