The problem of underdamped power oscillations in transmission systems is addressed in this paper. Different algorithms for STATCOM voltage control are designed to inject extra friction in order to eliminate such undesirable oscillating behaviour. In particular, a variable structure control law, combining continuous and discontinuous actions exhibits an especially good performance. The efficiency of the proposed control laws are tested and analysed through computer simulation.
