Dynamic voltage safety measurement and assessment index considering short-term voltage stability

Journal of Physics: Conference Series
Abstract At present, most of the short-term voltage stability criteria used in various power grids are based on voltage waveform, but these criteria can only determine whether the voltage is stable in the power system, but cannot give the relative degree of voltage stability.
