Abstract
Voltage stability is the most important things for a secure power system operation. A plenty of works have been developed to prevent voltage instability. This thesis presents a technique for optimal load shedding in power systems and a study on voltage stability. The main objective of this thesis is to develop an algorithm using MATLAB software to improve voltage stability by using load shedding process. Back tracking search algorithm is used to find the optimum loads to be shed. Contingency cases made by increasing loading using power flow method. Fast Voltage Stability Index (FVSI) and Voltage Collapse Power Indicator (VCPI) are in used to analyse the power flow continuation. The IEEE-14 bus system is simulated to analyse the power flow of the system by increasing the loads. This project have two phases, where the first phase consists literature review on voltage stability, voltage collapse, under voltage load shedding and back tracking search algorithm while the next phase are the development, testing and comparison of the algorithm with the manual calculation. The results indicate the minimum total amount of available load to be shed to make the system back to voltage stability region.
