Stealthy Cyber Attacks on Wide-Area Control Systems for Inducing Broadband Oscillations in Wind Farms
Abstract
This paper proposes a simulated oscillation cyber attack (SOCA) and corresponding defense strategy for wide-area damping control (WADC) of wind farm. SOCA simulates actual broadband oscillations in wind farms by calculating multiple oscillation modes from actual oscillation waveforms, which are then injected into the wide-area measurement signal, thereby degrading the system stability stealthily. Empirical mode decomposition based defense strategy is proposed to mitigate the effects of SOCA and maintains the function of WADC. Simulation studies on a two-area power system with wind farm verify the effectiveness of the proposed attack and defense strategies.
