Using Artificial Bee Colony Algorithm for STATCOM sizing and placement to Prevent Voltage Instability on Pakistan Power System

A Comparative Study of Static VAR Systems for ImprovingVoltage Stability in Expansion of Mining Projects with Gearless Motor Drives

“…Te literature shows some comparative studies of dynamic performance of aforementioned FACTS devices; for example, the authors in reference [4] compared the dynamic response and stability margin of SVC and STATCOM in weak and strong systems, the authors in reference [5] studied the infuence in dynamic voltage stability during LVRT in wind farms, the authors in references [6][7][8] compared SVC and STATCOM in dynamic reactive power support in diferent conditions (wind speed variation and grid fault) in wind turbines, while the authors in references [9][10][11][12] showed the importance of reactive power compensation to improve transient stability margin and power quality. When looking for applications of these FACTSs in electric power networks, the authors in reference [13] read up on the best location of a STATCOM in the Pakistan power system to improve voltage stability, the authors in reference [14] studied diferent voltage variations when the 100/145 MVAr FACTS is connected after the tripping of one overhead transmission line, the authors in reference [15] combined the D-STATCOM and a low THD SVC to enhance power quality, reducing voltage ficker and THD in a distribution grid, and the authors in reference [16] compared the dynamic performance of SVC and STAT-COM, showing reduction of the postdisturbance voltage recovery time after 3 phase faults. In reference [17], several series and shunt FACTS devices are combined in the Bangladesh power system to exploit the thermal limit but without the peculiarities of a mining installation.…”
