Load Flow Studies by CB Model Approach using UPFC

Sasi Kumar.M | Dr. Shaik Rafi Kiran

Abstract: This paper deals with steady state modeling of unified power flow controller (UPFC) by an alternative proposition. , This paper is focused on the steady-state modeling of UPFC for the direct implementation of the device in the Newton-Raphson (NR) power flow algorithm based on CB (Current Based) model due to current limitations are determinant to FACTS apparatus design, this model due to reduce the complexities of the computer program codes, availability of controlling in active, reactive power and voltage simultaneously or individual, the model overcome on the problem when UPFC is only link between two sub networks, NR power flow based on CB model is considered fast where most Jacobian elements are constant and equal to the terms of the nodal admittance matrix. The proposed UPFC model load flow has been tested using IEEE data test and shows it effectiveness in solving large network containing single or multiple UPFC devices.
