摘要:To study the influence of load model on voltage stability of the power system,taking the 3-machine 9-node AC/DC hybrid power system as an example, this paper establishes a differential algebraic mathematical model that takes into account the dynamic characteristics of each component of the system. Using the locally parameterized continuation method to track the equilibrium manifold,and nonlinear dynamic system bifurcation analysis method is applied to study.On this basis, the influence of load growth mode and load model adopted by regional dispatching department and planning department of state grid on voltage stability is analyzed and compared. The results show that the voltage instability is most likely to occur when the load nodes of the whole network increase proportionally, and the increase of the induction motor load is not conducive to the voltage stability of the system. © 2019 IEEE.
