At present, the evaluation of voltage stability

\r\nassessment experiences sizeable anxiety in the safe operation of

\r\npower systems. This is due to the complications of a strain power

\r\nsystem. With the snowballing of power demand by the consumers

\r\nand also the restricted amount of power sources, therefore, the system

\r\nhas to perform at its maximum proficiency. Consequently, the

\r\nnoteworthy to discover the maximum ability boundary prior to

\r\nvoltage collapse should be undertaken. A preliminary warning can be

\r\nperceived to evade the interruption of power system’s capacity. The

\r\neffectiveness of line voltage stability indices (LVSI) is differentiated

\r\nin this paper. The main purpose of the indices used is to predict the

\r\nproximity of voltage instability of the electric power system. On the

\r\nother hand, the indices are also able to decide the weakest load buses

\r\nwhich are close to voltage collapse in the power system. The line

\r\nstability indices are assessed using the IEEE 14 bus test system to

\r\nvalidate its practicability. Results demonstrated that the implemented

\r\nindices are practically relevant in predicting the manifestation of

\r\nvoltage collapse in the system. Therefore, essential actions can be

\r\ntaken to dodge the incident from arising.<\/p>\r\n","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 98, 2015"}
