Assessment of Sensitive Node for IEEE-30 Bus System by Load Variant

Abstract

Nowadays the load demand increases,these increases need to strengthen the system to fulfill the charge requirement reliably. To overcome such requirements, current systems have become more and more complex in nature. As of today.In this paper, we will have anemphasis on the weakness of most sensitive node in IEEE – 30 bus scheme. For this revision, we are using PSAT, a MATLAB Based Simulink & Simulation toolbox which utilizes L-index method for voltage strength analysis and sensitive nodes determination. For the evaluation of sensitive node, we have analyzed IEEE-30 bus system under the standard test data and then subjected to increase in load data by 5%, 10% and so on up to 40%. Moreover, then all the results are compared with the original power flow results of the IEEE-30 bus system for determining a furthermost sensitive node.
