Abstract

This paper first analyzes why voltage instability occurs in mature yet competitive power systems, and then investigate diverse voltage stability issues in deregulated power markets using a commercial transient simulation program EUROSTAG. Dynamic behaviors of major power system components, i.e., speed governor, excitation element, inductive motor, ULTC and mechanically switched shunt capacitor et al, are thoroughly examined by a small yet typical equivalent system. The presented simulation results help better understand the mechanism of the voltage collapse phenomena, and highlight the importance of dynamic reactive reserves, like generators, in dynamic voltage stability enhancement.
