Yousuf Mohammad Younes, Abdul Ghani A. A . Static Voltage Security Analysis of Single Branch Outage Contingency. International Journal of Computer Applications. 181, 35 ( Jan 2019), 22-25. DOI=10.5120/ijca2019918306
This research dealt with the analysis of the static security of the electrical power system according to the security constraints after the transient state of the single outage contingency to recognize the weak points of an electrical power system in future to help the engineers of the operation of the system by taking appropriate decisions to overcome the weaknesses and thus achieve secure systems. The IEEE 14 Bus system was selected as a model for study and representation in MATLAB. This possibility of contingency refers to N-1 Security analysis ( the symbol N represents all branches of the system: transmission lines or transformers, this is known as the Base Case which is secure ), according to Voltage Performance Index (PIV) . By selecting the best ratios for Off Load Tap Transformers and injecting the reactive power to the weakest load bus, the most severe disturbances were overcome.
