  4. Abstract:
  5. The size and complexity of modern power systems necessitate the use of Frequency Dependent Network Equivalents (FDNE) for part of the system. In order to give realistic simulation the frequency response of the equivalent must mach that of the system it represents. In this paper a method for developing FDNE is presented and demonstrated by approximation its admittance matrix Y by rational function in the frequency domain based on vector fitting method. The developed FDNE is accurate and efficient. An example showing the accuracy and efficiency of the developed FDNE when used to reduce a radial network is presented. ©2006 IEEE
