Improved ANN alpha th-order inverse TCSC controller for enhancing power system transient stability

The paper focuses on studying an improved structure of ANN alpha th-order i nverse, and its application as a TCSC controller in a real power system, co nsisting of 49 equivalent buses and 19 equivalent machines, to increase its transient stability. The ANN alpha th-order inverse, consisting of a singl e static ANN and a number of integrators, is used to eliminate the nonlinea rities of the power system. An additional linear feedback controller is des igned to enhance the stability of the linearised system. With almost the sa me structure (but different weights of ANN), this controller is first used to control a single-machine infinite-bus system and then the real multimach ine system. The satisfactory simulation results show that such a control st rategy has a promising future.
