A distributed control method for power system rotor angle stability based on second-order consensus

Conventionally, rotor angle stability control is based on centralized manner which exposes an increasing number of disadvantages with the growth in size and complexity of power systems. This paper proposes a distributed control method to enhance power system rotor angle stability based on the second-order consensus. In this method, one generator is selected as the leader and the others are followers. According to the second-order consensus theory, the control protocols for the leader and its followers are proposed. The influences of the coupling strengths and the communication topology on the performance of the proposed distributed control method are discussed with the simulation study on the IEEE 10-generator 30-bus system.
