摘      要：As power systems experience increased wind penetration,an effective analysis and assessment of the influence of wind energy on power system transient stability is *** paper presents a novel center of inertia(COI)approach to understand how integrated doubly fed induction generators(DFIGs)affect the transient dynamics of a power *** the COI coordinate,the influence of integrated DFIGs is separated into the COI related and individual synchronous generator related *** factors that affect the COI’s dynamic motion as well as the rotor dynamics of each individual synchronous generator with respect to the DFIG integration are *** further validate the analysis,comparative simulations of three different scenarios with varying DFIG capacities,access locations,and the replacement of synchronous generators are *** results show that the dynamics of the COI and the individual generators are affected by the integrated DFIGs via different mechanisms,and are sensitive to different variables in the DFIG’s integration condition.
