The Appliction of Modified Gausse-Newton Method for Improving Accuracy of Regime Parameters State Estimation and Control Action Adjusment in The Centralized Emergancy Control System

The key task of the operational dispatch control is providing the reliable energy supply and quality of electrical energy. The centralized emergency control system (CECS) plays an important role for solving this task, since the main target of the CECS is minimization of the emergency control volume by control actions (CA) identified in real time according to the current regime [1] . Information about the current scheme, regime and location, and, also, type, operational incident severity in the area of emergency control is collected in the central unit. Based on this information, the central unit identifies the required control actions, and then, these CA are transferred to control objects for implementation, increased accuracy of the CA and reduced redundancy of them. The mandatory component of the CECS is the state estimation (SE) module [2] . The power system regime, defined as the result of the SE, is the basic regime for stability problem solving and calculation of control-action adjustments, in cases if the required margin of stability in the post-accident regimes is not achieved.
