Based on an integrated static/dynamic information platform, security analysis functions can be upgraded from static to dynamic aspect for the space-time cooperative framework proposed in the part I of the three-part paper. This part investigates information reliability, optimal allocation of the dynamic data acquisition, data mining of field trajectories and/or simulation ones. The kernel functions of a dynamic energy management system (DEMS) are quantitative analyses of various securities, such as stability index and stability domain for thermal, angle, voltage, frequency and low-frequency oscillation respectively. Based on these early-warning functions, adaptive optimization for preventive, emergency, corrective and recovery controls can be implemented with the connection between the DEMS and control equipments.
