State estimation of electric power system for new technological systems

The paper presents the software package (SP) for solving the online state estimation (SE) problem. The problems solved in the SP, algorithms for their solution based on test equations and technical characteristics of the SP are listed. Considered are the up-to-date technological system for data acquisition and electric power system control (SCADA/EMS), configuration of its hardware, used in a number of electric power systems (EPS) of Russia. Besides some integration aspects of the SE software package into this system: the problems of SP information support, interaction with databases, development of platform-independent software package version are described. The results of the SP application in the Central Dispatching Board of the Unified EPS of Russia are presented. The prospects for development of the SP are considered.
