Estimation of ATC using PS-NR

Abstract

The recent changes in the power system structure has created renewed interest in power system operation. The open access and deregulation made the operation of system difficult as the power drawl and injection became open for all. This made Available Transfer Capability (ATC) estimation and enhancement an important factor both from commercial as well as operation point of view. In this paper, a PS-NR (pattern search and newton raphson) based technique for estimation of available transfer capability has been proposed. MATLAB and MATPOWER has been used for analysis of IEEE 24 BUS RTS system and IEEE 30 bus system using this technique. © 2017 IEEE.
