| In recent years,the integration of new energy generation into power grid and the wide application of information and communication technology bring new challenges to the transient stability control of power system.For power system after three phase short circuit,the system of the generator rotor frequency and Angle losing,lead to loss balance until the collapse of the system problem,in this paper,based on the consistency of the second-order multi-agent system theory,combined with the dynamics equation of generator model,design of control protocol control related equipment to perform an action,rapid system transient stability,The performance of the controller is verified by simulation.The main contents of this paper are as follows:For three phase short circuit fault in power system transient stability after recovery control,put forward a distributed controller based on consistency algorithm,the controller by the phasor measurement device for generator real-time status information,and use the adjacency matrix said local exchange of information,with quick response energy storage device for generator dynamic restore the stability of the level before failure,The stability margin of the system is improved.Lyapunvo theory is used to prove that the system can be rapidly realized under this controller,and the simulation results are verified in a New England10-machine 39-node system.An adaptive controller based on consistency algorithm is proposed to compensate the external disturbance in the system for the parameter uncertainty problems in practical engineering,such as modeling error and external disturbance.The controller uses the energy storage device to output(or absorb)the active power to the transmission bus to ensure that the power system is restored to the state before the fault and achieve the transient stability of the system.The simulation results verify the effectiveness and rapidness of the proposed control method in restoring transient stability control under actual constraints. |
