New Coherency Identification Approach and Its Application to Generator Tripping Algorithm

  • Received Date: 20 Nov 2008
  • In order to forecast the unstable modes of an electric power system,a new generator coherency identification approach was proposed by analyzing the state matrix of the system in unstable state.In this method,the eigenvalues and right eigenvectors of the state matrix are calculated to forecast the dominant unstable mode of the system and identify groups of coherent generators.The stability margin of the system is calculated by extended equal-area criterion.Through sensitivity analysis,generator tripping locations and ratios are searched to produce the optimal emergency generator tripping control strategy.Simulation results on the revised IEEE-39 bus system were provided to verify the proposed method.The results show that the proposed generator coherency identification algorithm is effective,and that the generator tripping control strategy based on sensitivity analysis can successfully prevent the system from transient instability.
