Performance analysis of some FACTS devices using Newton Raphson Load Flow algorithm

A comparative study and performance analysis is done for a number of FACTS devices in this paper. The models used are incorporated in an existing Newton Raphson Load Flow (NRLF) algorithm using standard IEEE 5 bus and 30 bus system. Problem of initialization for proper convergence of load flow is studied and findings are presented. Results are presented for comparison of performance analysis and evaluation of degree of suitability of selected FACTS devices.
