A method for secure control of interconnected synchronous generators based on game processing of fraud attacks

Abstract

The application belongs to the technical field of power grid automatic control, and discloses a kind of interconnected synchronous generator security control method based on game processing fraud attack, which constructs the multi-party dynamic game framework including fraud attack, optimal control input and optimal event triggering mechanism, and converts the security control problem into multi-agent non-cooperative game;By designing a dynamic optimal event triggering condition, and combining the fixed time convergence reinforcement learning algorithm to solve the Hamilton equation online, the optimal control strategy of the interconnected synchronous generator system model is generated.The method can ensure the rapid recovery of state variables such as power angle and speed when subjected to fraud attack, significantly reduce the number of communication triggers, effectively improve the security and resource utilization efficiency of the system, and solve the stable operation and communication resource optimization problem of interconnected synchronous generator under fraud attack.
