Collaborative fault-tolerant control of power systems comprising synchronous generator units

The inevitability of actuator faults within power systems, particularly those composed of synchronous generator units, poses a significant challenge. These faults, with the potential to induce frequency fluctuations, can lead to dynamic instability in the power system, emphasizing the critical need to address such issues. Exploring systematic fault-tolerant control mechanisms tailored for power systems with synchronous generator compositions holds paramount theoretical value and bears significant engineering implications. However, the intricate coupling effects between unknown actuator faults and interconnected outputs present a formidable obstacle. Conventional approaches, grappling with these intricate coupling effects, have proven insufficient in establishing a secure and stable control paradigm for power systems with synchronous generator units. In response to these challenges, this paper pioneers a novel distributed controller. Leveraging adaptive parameter design and deploying a sophisticated backstepping approach to estimate actuator fault terms, the controller ensures the stable operation of the power system in the face of actuator faults. To validate the efficacy of the proposed approach, simulations are meticulously executed using a representative large-scale power system as a case study. The simulation outcomes serve to affirm the effectiveness of the devised scheme, providing tangible evidence of its capability to ensure power system. stability amidst actuator faults.
