Inter-area oscillations are one of the factors that limit transmission capacity in large interconnected systems. In this paper we investigate the effects of increasing wind generation on inter-area modes and propose the use of additional control schemes for wind plants for mitigation of inter-area oscillations. Control schemes include droop control and inertial emulation, which are originally aimed at improving transient stability. The sensitivities of inter-area modes to droop control and inertial emulation gains are identified. Implementation of suggested controls schemes via collocated energy storage devices is also explored.
