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 power output and successfully attenuate these oscillations. Variety of control design methods were proposed for this service. In this paper focus is given to the most popular technique based on residues. Authors demonstrate on a small 4-machine 12-bus grid that residues may not provide sufficient information for effective damping control design. Hence, it is proposed to give more attention to additional indices like transfer function zero location and interactions between mode of interest and other system dynamics. Consequently, additional rules are proposed for residue based damping control design.
