Voltage stability of electric power systems is a challenging topic both theoretically and in practice. This entry touches briefly on the main aspects of the problem and highlights theoretical foundations and fundamental methods for voltage stability analysis. The single-load radial system is used to introduce basic concepts, such as the PV curve, and the instability mechanism, while the implications for a meshed, multiple-load system are briefly outlined. Some applications to practical problems are briefly enumerated.
