Abstract

Through the analysis of the numerical solution methods for ordinary differential equations, a concept of varying order control for transient stability calculation is proposed, viz. when computing the system trajectories, the orders of state variables are selected dynamically and separately according to the precision demand. Based on this concept, the method of varying order control in Taylor series expansion technique is presented for transient stability analysis. The validity and precision of this method is verified in the practice of the Transient Stability analysis. The numerical simulation results indicate that this method improves the calculation efficiency and has practical value in Transient Stability analysis for power systems.
