Stabilization A High Voltage ACDC Power Systems I. Evaluation Of Control Strategies

Various optimal and suboptimal stabilizing signals for a single machine infinite bus system connected through an ACDC link have been investigated. The controls in order of effectiveness of transient control are the linear state regulator control, a quasioptimal proportional control, output regulator controls from terminal voltage and frequency, and frequency and acceleration. From implementation viewpoint the proportional control is preferred. This scheme can also be easily extended to Include the nonlinearities in the system dynamics.
