Evaluation of residue based power oscillation damping control of inter-area oscillations for static power sources

摘要: Low frequency inter-area oscillations are known stability issue of large interconnected electrical grids. It was demonstrated that additional control loop can be applied for static power sources, like FACTS, HVDC or modern Wind Power Plants, to modulate their output and successfully attenuate these oscillations. Variety design methods were proposed this service. In paper focus is given the most popular technique based on residues. Authors demonstrate a small 4-machine 12-bus grid residues may not provide sufficient information effective damping design. Hence, it give more attention indices transfer function zero location interactions between mode interest other system dynamics. Consequently, rules residue
