ESTIMATION OF STEADY STATE STABILITY LIMITS FOR ON-LINE INTERCONNECTED POWER SYSTEM CONTROL

The present paper describes algorithm for operative evaluation of maximum transmission capacity of power system using a periodic static stability conditions and model parameters specifying current state of the circuit and system regime. Model. parameters are identified in step with the process using teledate obtained in the nodes of intersystem communications. On-line constraints for parameters under control correspond to the current limit of the power system transmission capacity. Results of investigation of adaptive identification algorithm were obtained for real power system.
