Transient Stability Distributed Control of Power System with External Energy Storage

Summary: Aiming at the transient stability control problem when some controllers fail in the power system, a distributed adaptive control method is proposed to improve theTransient Stability of Systems.Leadership based on second-order nonlinear multi-agent systems—Follow the consistency theory, obtain real-time information of neighbor generators through the communication network, and useThe relative power angle and relative speed information between the local generator and its neighbor generators are designed to control the controller, and control the action of the external energy storage device to quickly restore the transient stability of the system after a fault.Convergence proof using Lyapunov stability theory.Finally, in New England39In-depth analysis of the performance of the controller in the node test system, and considering the impact of some controller failures on system performance under information attack, the simulation study further verifies the feasibility of the proposed distributed control methodspan>.
