Steady-State Voltage Stability Enhancement by Using Nonlinear Participation Factor

Abstract:

Reactive power plays a key role in the power systems operation and stability. By using theory of normal forms of diffeomorphism, this paper proposes an index of bus voltage nonlinear factor, used to measure the effect of buses to the steady-state voltage stability. In order to verify the effectiveness of the proposed method, case studies are performed using the New England 39-bus power system. At the view of steady-state voltage stability enhancement, the results show that the bus voltage nonlinear factor is an effective index. It can give the correct indication of reactive power compensation dispatch.
