Analysis of Cyber Attacks on Wind Power Generation Systems in Damping Inter-area Oscillations of Power Systems

With the application of damping controllers developed using remote feedback signals provided by phasor measurement unit (PMU) and wida-area measurement system (WAMS), the wind power generation system (WPGS) can damp the inter-area oscillations of power system. Nevertheless, the damping control system of WPGS may suffer from malicious cyber attacks, which will deteriorate the performance of WPGS and even destabilize the power system operation. This paper considers the various types of cyber attacks, including false data injection attack (FDIA), time-delay attack (TDA), denial of service (DoS) attack, coordinated cyber-physical attack (CCPA), and analyzes the effects of these cyber attacks on WPGS in damping inter-area oscillations of power system. Simulation studies are carried out on a two-area four-machine power system integrated with WPGS to investigate the cyber security of WPGS.
