Abstract	Dynamic security region (DSR) is a new method for dynamic security analysis and assessment in an electrical power system which is based on modern nonlinear differential dynamic system and stability boundary theory. Since the DSR is defined in the pre-faults injection parameter space, the idea of "region" in this method is a step-by-step integration method. different from traditional "point by point" method, including step-by-step integration method in time domain, Lyapunov direct method, artificial intelligence method and so on. The characteristics of DSR also show it is more available and practicable for on-line application. In published literature on DSR, the research focuses on theoretical analysis and practical approach in dynamic security analysis. The literature on quantitative analysis of DSR are very few because the relevant measure and margin have not been established. In this paper, a natural measure (or margin) and the relevant sensitivity analysis of DSR is proposed for the first time. Then a new framework that applies DSR method in on-line load dispatch and transient stability control is formed. The respective algorithms and work examples are presented to prove the practicability and validity of the scheme.
