Abstract :
This paper presents the calculation of several static indices for voltage collapse on the Vietnamese power system for two configurations. The long-term time simulation, by taking into account dynamic aspects, with the help of the Eurostag program is also presented. From these indices, countermeasures for voltage collapse on the Vietnam power system are proposed. Methods of voltage control and rescheduling of active/reactive power generations are proposed in order to reduce the risk of voltage instability and increase the reactive reserve of generators
