STABILIZATION OF POWER-SYSTEMS USING DECENTRALIZED CONTROL

The problem of stabilizing multi-machine power systems following elect rical disturbances is considered and a method for generating stabilizi ng signals is proposed. A two-level computational algorithm is develop ed to determine the state-feedback controller, the stabilizing gains o f which are implemented on-line and in a decentralized fashion. Simula tion studies on a small power system indicate that the proposed method ology does indeed produce stabilizing signals which are effective in i mproving the dynamic behavior of the sample power system studied.
