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.

“…In [13], trajectory sensitivities is used for multi-contingency preventive control. The method proposed in [14] is based on the idea that increasing coherency between generators in the transient behavior following a system perturbation gives rise to a more stable system. In [15], the transient energy function (TEF) method is used to check the dynamic security of the system and the coherent behavior of generators is used to find a new generation configuration.…”

Abstract-The increased penetration of wind farm in distribution networks has brought changes in the performance of the whole system. Such disadvantages when connecting one of these distributed generation sources is reduced voltage and power stability of the AC network. This phenomena can cause the connected electricity consumers to suffer from disturbances. This paper investigates the use of a static synchronous compensator (STATCOM) to improve the short circuit current contribution in the network which will include balanced and unbalanced faults. The wind farm is equipped with fixed-speed wind turbines driving squirrel-cage induction generators. The IEEE 30-bus distribution test system is used to see the performance of the system under distribution level. Simulation studies are carried out in the DIgSILENT software.
