  • Abstract:
  • The FACTS known as flexible ac transmission systems devices are solid state converters designed on voltage source converter and now the approach of engineers towards planning and operations of power systems by the implementation of FACTS devices. It is flexible in the sense that it can modified the impedance of line, control the voltage magnitude, power flow in designated routes and phase angle at chosen bus. It has the benefit of FACTS controller to enhance the power transmission capacity, secure loading up to their thermal capability of lines, power flow control flexibility and enable better utilization of available generation. The FACTS devices to be applied in series, shunt or series – shunt with the transmission line to control the operation parameters of electric power circuits. It has applications in power flow control, enhancement in power transfer capability, reduce the power losses, voltage control, reactive power compensation, stability improvement, improve the security, power quality improvement and interconnections of renewable and distributed generations. Optimal placement of FACTS devices can significantly reduce costs of generation re-dispatch in a Balancing Market, and thus improve system efficiency. The proposed methods are applied on IEEE 14 bus system and results are analyzed.
