| Abstract | ||
| This paper presents a study of static synchronous compensator (STATCOM). One of the Flexible AC Transmission System (FACTS) devices, it can significantly improve power systems stability. Consisting of voltage sourced converters connected to an energy storage device on one side and to the power system on the other, it specifically can provide reactive support to buses. This work presents a simple algorithm for identifying weak buses to determine the best location for STATCOM. Singularity of the power flow Jacobian matrix as an indicator of steady-state stability has used, the sign of the determinant of the load flow Jacobian was used to determine the system stability, by computing eigenvalues, eigenvectors , minimum singular value of load-flow Jacobian Matrix and sensitivity analysis between power flow and bus voltage changes. Load flow analysis of the Iraqi grid 400 KV network has been carried out using Newton- Rephson Method with and without STATCOM. The result of Load flow analysis show improvement in bus voltage with the use of STATCOM in the system. | ||
