摘要：
This paper addresses numerical oscillations encountered in power system dynamic simulation resulting from trapezoidal numerical integration rule. Two methods are presented to eliminate the numerical oscillations: trapezoidal with numerical stabilizer method and Gear's second order method. A detailed comparison is given regarding the accuracy of the trapezoidal rule, trapezoidal with numerical stabilizer method, and Gear's method. The validity of the new methods is demonstrated in the simulation of a power electronic circuit within Virtual Test Bed. The new methods are of great significance in performing a meaningful simulation for power electronics circuits.
